A particle with charge 5 . 0- µ C is placed at the corner of a cube. (Physics Help)? A particle with charge 5.0-µC is placed at the corner of a cube. The total electric flux in N * m^2 C through all sides of the cube is: B) 7.1 x 10^4 D) 1.4 x 10^5
Gauss law states that the electric flux through any closed surface is proportional to the net electric charge inside the surface. This is expressed mathematically in the form of:
Φ = Q / εo
Where,
Φ = the electric flux = unknown (which we have to find for)
Q = the net electric charge = 5.0 µC = 5 E-6 C
εo = the permittivity of free space = a constant value = 8.85 E-12 C^2 / N m^2
Plugging in the values into the equation will result in:
Φ = 5 E-6 C / (8.85 E-12 C^2 / N m^2)
Φ = 564,971.75 Wb = 5.6 x 10^5 Wb

A young boy was riding his bicycle down the street when he hit a parked car. what was the second collision?
The second collision in this scenario is likely to be when the boy's body hits some interior part of the car after he initially impacts with the car. This is because of the conservation of momentum which needs to go somewhere after the initial collision, often resulting in a further collision.
Explanation:In the scenario you explained, a young boy was riding his bicycle and hit a parked car. This is referred to as the first collision. The second collision in this context would be the boy's body hitting some interior part of the car (like the car door or windshield) after the initial impact with the car.
This is an application of the physics principle of conservation of momentum. Initially, the bike and the boy have some momentum, and after hitting the parked car, that momentum needs to go somewhere - which often results in a second collision. However, the exact nature of the second collision could depend on a few factors such as the speed of the bicycle and the angle at which the bicycle hit the car.

For maximum visibility while backing a vehicle, the driver should use all mirrors, check blind spots, ensure rear visibility is unobstructed, and back slowly. It is also crucial that the vehicle is well-maintained with functioning lights and signals.
For maximum visibility when backing a vehicle, a driver needs to be highly alert and use all available visual aids. This includes checking all mirrors, turning to look over each shoulder for blind spots, and using the rear-view camera if the vehicle is equipped with one. It's important to have a clear view of the path behind the vehicle, which means ensuring that the rear windshield is free of obstructions like stickers, dirt, and snow. Furthermore, it's essential for the driver to move slowly and smoothly, allowing more time to react if an obstacle appears. A step-by-step approach includes:
Adjusting all mirrors for the widest field of vision.Checking for obstacles around the vehicle before getting in.Ensuring the rear windshield is clear.Turning to physically check blind spots.Backing slowly to maintain control and react to changes.It's also crucial that the vehicle is in good condition, as noted in 'KNOW YOUR HIGHWAYS and BE SURE TO HAVE YOUR CAR IN GOOD CONDITION', including functioning lights and reverse signals to alert nearby pedestrians and motorists. Being aware of the surrounding environment, such as obeying unknown speed limits as inferred from the scenario with the test car, increases safety while maneuvering.
Determine the displacement of a plane that is uniformly accelerated from 66 m/s to 88 m/s in 12 sec
The displacement of a plane that is uniformly accelerated is equal to 925.7 m.
What is the equation of motion?The equations of motion can be described as the relationship of the motion of any physical system as the function of time and set up the relationship between the acceleration, velocity, time, and displacement of a moving system.
Given, the initial velocity of the plane, u = 66 m/s
The final velocity of the plane, v = 88 m/s
The time taken by the plane, t = 12 sec
From the first equation of motion we can calculate the acceleration:
v = u + at
88 = 66 + a(12)
a = 1.83 m/s²
From the second equation of motion we can calculate the displacement of the plane:
S = ut + (1/2)gt²
S = 66 × 12 + (1/2)× 9.8× (12)²
S = 925.7 m
Therefore, the displacement of the plane is 925.7 m.

An object has a mass of 15 kg. on planet x, the object weighs 126 n. the force of gravity on planet x is _____. 0.12 m/s2 8.4 m/s2 1875 m/s2
The force of gravity on planet x is equal to 8.4 m/s². Therefore, option (B) is correct.
What is the weight of the object?The weight of a body can be defined as the force acting on the body due to the gravity of the earth or any planet. Weight can be described as a vector parameter if the gravitational force is exerted on the object.
The measurement unit for weight is similar to that of force, which (SI) is the newton (N). A body with a mass of 1 Kg has a weight of 9.8 N on Earth's surface, and about 1/6th as much on the Moon.
The mathematical expression to determine the weight of an object is written as follows:
W = mg
Given the mass of the given object, m = 15 Kg
The weight of the object, W = 126N
The force of gravity on planet x will be equal to:
126 N = 15 Kg × g
g = 126/15
g = 8.4 m/s²
Therefore, the force of gravity on planet x is equal to 8.4 m/s².

The distance, in feet, a moving object has traveled after t seconds is given by 2t/(4 + t). find the acceleration of the object after 5 seconds. (round your answer to three decimal places.)
Final answer:
To find the acceleration of a moving object after 5 seconds, given the distance function 2t/(4 + t), we first find the velocity by differentiating the distance function, then find the acceleration by differentiating the velocity. The acceleration after 5 seconds is approximately -0.022 m/[tex]s^2[/tex].
Explanation:
The question involves finding the acceleration of a moving object after 5 seconds, given that the distance it has traveled after t seconds is represented by the function 2t/(4 + t). To find the acceleration, we first need to determine the velocity function by differentiating the distance function with respect to t, and then find the acceleration by differentiating the velocity function with respect to t again.
The velocity v(t) is the first derivative of the distance function s(t) = 2t/(4 + t). Using the quotient rule for differentiation, v(t) = d/dt [2t/(4 + t)]. Calculating the derivative gives us v(t) = 8/(4 + t)^2.
The acceleration a(t) is the derivative of the velocity function. So, a(t) = d/dt [8/(4 + t)^2]. Differentiating this gives a(t) = -16/(4 + t)^3.
Plugging t = 5 into the acceleration function, a(5) = -16/(4 + 5)^3 = -16/729. Therefore, the acceleration of the object after 5 seconds is approximately -0.022 m/[tex]s^{2}[/tex], rounding to three decimal places.

In a typical rear-end collision, the victim's ________ is accelerated faster and harder than the torso.
Answer: In a typical rear-end collision, the victim's head is accelerated faster and harder than torso.
Explanation:
When a vehicle crashes into the one in front of it then this type of collision is called rear-end collision.
The lighter part of the victim would have more acceleration than the lower heavy part of the victim. Here, the lighter part of the victim is head and the heaver part of the victim is torso.
Therefore, in a typical rear-end collision, the victim's head is accelerated faster and harder than torso.
A drowsy cat spots a flowerpot that sails first up and then down past an open window. the pot was in view for a total of 0.49 s, and the top-to-bottom height of the window is 1.80 m. how high above the window top did the flowerpot go?
Final answer:
To determine the height above a window a flowerpot reached, we use kinematic equations for motion under gravity. By dividing the time the pot was in view by 2, and knowing the window's height, we calculate the initial velocity and then the additional height the pot reached above the window.
Explanation:
The question concerns a flowerpot moving past a window and how high it goes above the window after being in view for 0.49 seconds. To solve this, we can use kinematic equations of motion under constant acceleration due to gravity. We assume the pot goes up and then comes down passing the window twice, once going up and once going down. The time it takes to pass the window should be the same in both directions.
Divide the total time in view by 2 to find the time for one pass: 0.49 s / 2 = 0.245 s. Next, use the kinematic equation s = ut + 1/2at^2, where s is the distance, u is the initial velocity (0 m/s at the top of the window for the upward direction), a is the acceleration (gravity, which is -9.8 m/s^2 here), and t is the time the pot is in view. We can calculate the initial velocity needed to reach the top of the window in 0.245 s and then use that to find how high above the window top the flowerpot went.
Since the flowerpot was seen passing the entire height of the window (1.80 m), we use this distance to find the initial velocity it had when it first appeared at the bottom of the window. Using the kinematic formula u = (s - 1/2at^2) / t, we can solve for u. Then, apply this as the final velocity in the equation for its journey starting from the top of the window on its way up. With the final velocity at the top being zero (at the peak of its trajectory), we can now find the displacement above the window using the kinematic formula s = ut - 1/2at^2, and solve for s, where this time u is our previously calculated initial velocity and a is -9.8 m/s^2 (upward direction).

What is connector called on a car radio antenna?
Motorola connecter or a Motorola antenna plug is a connector used on a car radio antenna. It is a common coaxial cable RF connector used mainly in the locomotive trade for linking coaxial feed line from the antenna to the radio receiver. The pin of the connector is fused to the middle of the conductor of the coaxial cable starting the antenna. Its adjacent ground forms a 1.5inch long sleeve all over the coax. By rubbing the male plug alongside the female socket, the sleeve contains one or more longitudinal spring that offer sufficient electrical contact.
The connector on a car radio antenna is typically attached to the base of the antenna rod, facilitating the transmission and reception of radio waves.
The connector on a car radio antenna is typically attached to the base of the antenna rod.
The rod of the antenna is fed by a coaxial cable, where the center conductor is connected to the base of the rod, and the sheath is attached to the car body.
Antennas on cars, such as the commonly seen whip antenna, are important for converting electric power into radio waves for transmission and reception.

Which condition describes an object having terminal velocity?
a. gravity > air resistance
b. gravity < air resistance
c. gravity = air resistance
Answer:
C. Gravity = air resistance
Explanation:
An object falling down has two forces acting on him:
- Gravity, which acts downward --> the magnitude of this force is constant (equal to [tex]mg[/tex], where m is the mass of the object and g is the gravitational acceleration)
- Air resistance, which acts upward --> the magnitude of this force is directly proportional to v, the speed of the object
When the object starts its fall, the speed is zero (v=0) so only gravity acts and it accelerates the object downward. Therefore, the speed of the object increases, and so does the air resistance, until a point where the air resistance becomes equal to gravity (which is constant): when this occurs, the acceleration of the object becomes zero (because forces are balanced), so the object continues its fall at constant velocity, called terminal velocity.
