The best way to avoid overloading your boat is to ensure that the total weight does not exceed the recommended capacity. Distribute the weight evenly and keep the center of gravity low. Follow safe boating practices and prioritize everyone's safety.

The best way to avoid overloading your boat is to ensure that the total weight of the boat, including passengers and cargo, does not exceed the maximum recommended weight capacity. This can be determined by checking the boat's capacity plate or consulting the manufacturer's specifications. It is also important to distribute the weight evenly throughout the boat, keeping the center of gravity low to maintain stability. Finally, always follow safe boating practices and avoid overloading your boat to prevent accidents and ensure everyone's safety.

Answer: Move away.

Explanation:

We know that like charges repel each other and unlike charges attract each other. So, when two negatively charged particles are brought close together and then released, they move away from each other because of their similar charge and hence, they repel each other. The electrostatic force of repulsion acts between the two similar charged particles.

The initial speed of the football can be determined using the equations from projectile motion, considering the horizontal distance of the throw and the angle at which the ball is thrown.

The question is asking to determine the initial speed of the football when thrown by the quarterback. This is a projectile motion question and it involves two dimensions. Given that the quarterback is throwing the ball at an angle of 25.0 degrees and the ball lands at the same height, we can find the initial speed using the horizontal distance of the throw (20.0 m) and the equation for horizontal displacement in projectile motion: x = V0 * t * cos(θ).

Here, we do not have the throwing time (t), and hence, we use another equation from projectile motion where time (t) = [2 * V0 * sin(θ)] / g; where g is the gravity. Substituting this time (t) in the first equation, and solving for V0, we will get the initial speed of the thrown football.

The hypothesis about the effect of increasing the total mass of the carts on the final velocity after an inelastic collision will be as follows;

"If the total mass of two colliding carts is increased then the final velocity of the carts drops, because mass and velocity define momentum and momentum is preserved during an inelastic collision".

Explanation:

In an inelastic collision, the two objects stick on each other and move with a common velocity.

If m₁ and m₂ are the mass of two objects. They are moving with initial velocities u₁ and u₂. Let V be the final velocity of both objects.

Using conservation of momentum as :

[tex]m_1u_1+m_2u_2=(m_1+m_2)V[/tex]

[tex]V=\dfrac{m_1u_1+m_2u_2}{m_1+m_2}[/tex]

If the mass of the colliding objects increases then the velocity decreases because there is an inverse relationship between the mass and the velocity.

Answer : Electric potential, [tex]V=1.8\times 10^0\ V[/tex]

Explanation :

It is given that,

Magnitude of electric field, [tex]E=875\ N/C[/tex]

Distance between two plates, [tex]d=0.002\ m[/tex]

The relation between the electric field and the electric potential is given by :

[tex]E=\dfrac{V}{d}[/tex]

[tex]V=E\times d[/tex]

[tex]V= 875\ N/C\times 0.002\ m[/tex]

[tex]V=1.75\ V[/tex]

or

[tex]V=1.8\times 10^0\ V[/tex]

So, the magnitude of electric potential is given by option (2).

Hence, this is the required solution.                                                                                                

final velocity = initial velocity + (acceleration x time) 
3.9 m/s = 0 m/s + (acceleration x 0.11 s) 
3.9 m/s / 0.11 s = acceleration 
30.45 m/s^2 = acceleration 

distance = (initial velocity x time) + 1/2(acceleration)(time^2) 
distance (0 m/s x 0.11 s) + 1/2(30.45 m/s^2)(0.11s ^2) 
distance = 0.18 m

Answer:

(a). The acceleration is  35.5 m/s².

(b). The distance is 0.214 m.

Explanation:

Given that,

Speed = 3.9 m/s

Time = 0.11 s

We need to calculate the acceleration

Using formula of acceleration

[tex]a = \dfrac{v_{f}-v_{i}}{t}[/tex]

Put the value into the formula

[tex]a =\dfrac{3.9-0}{0.11}[/tex]

[tex]a=35.5\ m/s^2[/tex]

We need to calculate the distance

Using equation of motion

[tex]s = ut+\dfrac{1}{2}at^2[/tex]

Put the value in the equation

[tex]s =0+\dfrac{1}{2}\times35.5\times(0.11)^2[/tex]

[tex]s=0.214\ m[/tex]

Hence, (a). The acceleration is  35.5 m/s².

(b). The distance is 0.214 m.

We are given that:

A) Mechanical energy

Explanation:

I got it right on Edge 2022

The acceleration produced by a net force on a body is inversely proportional to the mass of the body is true.

A net force acting on an object causes it to accelerate, which would be inversely proportional to such mass of the object and therefore directly proportional to the force's size as well as direction.

A physical body's mass would be the total amount of matter it contains. Inertia, or the body's susceptibility to acceleration when a net force would be applied, is another property that may be measured.

It is known that F = ma, hence the acceleration produced by a net force on a body is inversely proportional to the mass of the body.

The maximum height is approximately 602.878 feet, and the range is approximately 1,204.755 feet, rounded to three decimal places.

Certainly, let's calculate the maximum height and range of the projectile.

Given:

Initial height (h₀) = 4 feet

Initial velocity (v₀) = 600 ft/s

Launch angle (θ) = 45 degrees

Acceleration due to gravity (g) = 32 ft/s² (assuming downward as positive)

Vertical Motion:

h = h₀ + v₀ sin(θ) t - 1/2 gt²

At the maximum height, v_y = 0:

v_y = v₀ sin(θ) - gt = 0

Solving for t, we get the time of flight. Once we have t, we can substitute it back into the vertical motion equation to find the maximum height (h).

t = v₀ sin(θ) / g

h = h₀ + v₀² sin²(θ) / (2g)

Horizontal Motion:

R = v₀ cos(θ) * time of flight

R = v₀ cos(θ) * v₀ sin(θ) / g

Now, let's perform the calculations:

t = 600 sin(45°) / 32

t ≈ 5.774 seconds

h = 4 + 600² sin²(45°) / (2 * 32)

h ≈ 602.878 feet

R = 600 cos(45°) * 5.774

R ≈ 1,204.755 feet

Answer:

Acceleration of ball (a) = 9.8 m/s^2 Speed (v) = 24.5 m/s Time (t) = Acceleration / Time = v / a = 24.5/9.8 = 2.5 s So it will take 2.5 seconds to reach that speed.

Explanation:

Final answer:

Average speed is determined by dividing the distance traveled by the time of travel.

Explanation:

Average speed is calculated by dividing the distance traveled by the time of travel. It is a scalar quantity and does not have a direction associated with it.

To convert 3.8 km/sec to miles/year, multiply by the conversion factors: 3600 km/hour and 0.621 miles/km.

To convert 3.8 km/sec to miles/year, we need to first convert km/sec to km/hour, and then convert km/hour to miles/year.

1 km/sec is equal to 3600 km/hour (since there are 3600 seconds in an hour). So, 3.8 km/sec is equal to 3.8 x 3600 = 13,680 km/hour.

Now, to convert km/hour to miles/year, we can use the conversion factor of 0.621 miles/km. Therefore, 13,680 km/hour can be converted to miles/year by multiplying it by the conversion factor:

13,680 km/hour x 0.621 miles/km = 8,498.68 miles/year.

The apparent force that seems to pull an object outward from the center of a curve is known as centrifugal force, which is actually the result of inertia in a rotating frame. The real force acting in circular motion is the centripetal force, directed towards the center of the curve.

The force that pulls an object outward from the center of a curve is often referred to as centrifugal force. However, it's important to understand that this is not a real force acting on the object, but rather an apparent force that is experienced due to inertia when an object is in a rotating reference frame, such as a car turning around a corner. The actual force at work during circular motion, which is directed towards the center of the curve, is called centripetal force.

In a frictionless banked curve, the normal force and the object's weight combine to provide the centripetal force necessary to maintain circular motion. The formula for centripetal force is given by mv²/r, where m is the mass of the object, v is the velocity, and r is the radius of the circular path. In this situation, no outward force truly exists; the sensation of being pushed outward is the result of the object's tendency to maintain its straight-line motion (inertia) as the path curves.
