What results from splitting an atomic nucleus?
2 atoms identical to the original atom are formed
2 new atoms different from the original atom are formed
2 atoms are chemically joined
1 new atom different from the original is formed

Answers

"2 new atoms different from the original atom are formed" because the results of splitting an atomic nucleus is two *smaller* nucleus.
Final answer:

Splitting an atomic nucleus, also known as nuclear fission, results in the formation of two new atoms different from the original. These new atoms are often smaller, more stable, and radioactive.

Explanation:

When an atomic nucleus is split, the process typically results in the formation of two new atoms which are different from the original atom. This process is referred to as nuclear fission. It's important to note that nuclear fission often results in atoms that are smaller and more stable than the original, but they are not necessarily identical. These new atoms are often radioactive, meaning they emit radiation. Additionally, an enormous amount of energy is usually released during the process.

After the fission of U-235 takes place, how many neutrons does the missing nucleus have?

A) 84

B) 85

C) 141

D) 143

Answers

Answer:

B) 85

Explanation:

In the nuclear fission of uranium-235, a nucleus of uranium-235 absorbs a slow-moving neutron and then decays into a nucleus of Kripton-92, a nucleus of Barium-141 (which is the missing nucleus in the figure) and three more neutrons.

Knowing that:

- Uranium has atomic number 92, so it has 92 protons

- Kripton has atomic number 36, so it has 36 protons

- Barium has atomic number 56, so it has 56 protons

We can calculate the number of neutrons in the nucleus of barium, since we know that the total number of neutrons must be conserved. We have:

- On the left side of the reaction: (235-92) neutrons of the uranium + 1 neutron absorbed = 144 neutrons

- On the right side of the reaction: (92-36) neutrons of the krypton + X neutrons of the barium + 3 neutrons = 144

So we get:

56 + X + 3 = 144

X = 85

So, the nucleus of barium has 85 neutrons.

Only one force acts on an object. can the object have zero acceleration? can it have zero velocity? explain

Answers

If only one force is acting an object it can have zero acceleration but it cannot have zero velocity. This occurs because acceleration is a change in speed, therefore when one force is acting upon the object the speed will remain constant. It can't have zero velocity because if one force is acting upon it then it is moving and no matter what that means it will have a velocity that isn't zero.
Final answer:

An object with only one force acting can indeed have zero acceleration and zero velocity. According to Newton's first law, zero net external force on an object will maintain its state of motion, implying constant velocity (including a zero velocity) and zero acceleration.

Explanation:

Yes, an object with only one force acting on it can have both zero acceleration and zero velocity. Based on Newton's first law, if the net external force acting on an object is zero, the object will maintain its state of motion. This implies it can have a constant velocity, including zero velocity. Acceleration is a measure of the change in velocity, thus, if the velocity of the object remains constant, the acceleration is zero.

For instance, consider a car parked on a flat road. The car experiences forces: gravity pulling it down and the normal force (the force exerted by the surface that opposes the weight) pushing it up. These forces are balanced, making the net force zero.

Hence, the acceleration of the car is zero, and in this case, the velocity is also zero as the car is at a standstill. However, when the car is moving at a constant speed, despite any existing forces, if they are balanced and the net external force is zero, the velocity remains constant and acceleration is zero.

a pebble is dropped down a well and hits the water 1.5 seconds later. using the equations for motion with constant acceleration, determine the distance from the edge of the wall to the water's surface.

Answers

Let h = the distance from the edge of the wall to the water surface (m).

Use g = 9.8 m/s² and neglect air resistance.

The initial vertical velocity of the pebble is zero.
Because the pebble hits the surface of the water after 1.5 s, therefore
h = (1/2)*(9.8 m/s²)*(1.5 s)² = 11.025 m

Answer:  11.025 m

Answer: 11.025

Explanation:

Let h = the distance from the edge of the wall to the water surface (m).

Use g = 9.8 m/s² and neglect air resistance.

The initial vertical velocity of the pebble is zero.

Because the pebble hits the surface of the water after 1.5 s, therefore

h = (1/2)*(9.8 m/s²)*(1.5 s)² = 11.025 m

Light rays that enter the hole of a pinhole camera form _____ on the back wall of the camera.

Answers

That's an inverted real image.
Final answer:

Light rays entering a pinhole camera form an inverted image on its back wall; the idea is inverted because light travels in straight lines and doesn’t reorient upon entering the pinhole.

Explanation:

Light rays that enter the hole of a pinhole camera form an inverted image on the back wall of the camera. This occurs as the light rays from an object diverge, and only a tiny portion of these rays enter the pinhole, causing them to form an image. Notably, this image is flipped upside down - or inverted - because light travels in straight lines, and the rays do not reorient themselves after entering the pinhole. An important aspect to understand is that these rays do not cross each other upon entering the pinhole, thereby ensuring the formation of a clear and inverted picture on the back wall of a pinhole camera. This is fundamentally akin to how light enters the human eye to form an image on the retina, where a similar effect is also observed, resulting in the need for the brain to flip the image right-side up for us to perceive our surroundings correctly.

An elevator accelerates upward at 1.2 m/s 2 . the acceleration of gravity is 9.8 m/s 2 . what is the upward force exerted by the floor of the elevator on a(n) 76 kg passenger? answer in units of n.

Answers

We can find the force by using the following formula;
N = ma +  mg
Fa = ma = 76 x 1.2 = 91.2
Fg = mg = 76 x 9.8 = 744.8
N = 91.2 + 744.8 = 836
So, the force is 836 N.

The upward force exerted on the passenger is 836 N.

The given parameters;

acceleration of the elevator, a = 1.2 m/s²acceleration due to gravity, g = 9.8 m/s²mass of the object, m = 76 kg

The upward force on the object can be determined by applying Newton's second law of motion.

Since the elevator is ascending upwards, the force on the elevator will become greater and the passenger feels a heavier weight.

∑F = ma + mg

F = m(a + g)

F = 76(1.2 + 9.8)

F = 836 N.

Thus, the upward force exerted on the passenger is 836 N.

What causes the vivid bands seen in jupiter's upper atmosphere?

Answers

Jupiter has two types of bands around it; the zones and the belts.

The zones are the light-colored bands that are formed when the gases of Jupiter's atmosphere rise upwards.

The belts, on the other hand, are the dark-colored bands that are formed when the gases of Jupiter's atmosphere fall downwards.

The colors in these bands are formed as a results of the slight difference between their temperatures as well as the difference in the chemical composition.

A particular lever can lift a load with 80 percent efficiency. If 40 N of effort is applied 2.5 meters from the fulcrum, then what is the maximum load that can be lifted 1.5 m from the fulcrum?

A) 5333 N
B) 1920 N
C) 66.7 N
D) 53.3 N

Answers

Refer to the diagram shown below.

For dynamic balance,
1.5W - 2.5F = 0
W = (2.5*F)/1.5
     = (2.5*40)/1.5
     = 66.667 N

Because the lever is 80% efficient, the actual maximum load that can be lifted is
0.8*66.667 = 53.3 N

Answer: D.  53.3 N

Final answer:

To find the maximum load a lever can lift given its efficiency and distances from the fulcrum, calculate the mechanical advantage, then adjust for efficiency. The maximum load with 80 percent efficiency is 53.3 N, answer D.

Explanation:

The question is about calculating the maximum load that a lever can lift, given its efficiency, the effort applied, and the distances from the fulcrum on both the effort and the resistance arms. To solve this problem, we use the concept of mechanical advantage (MA) and take into account the efficiency of the lever.

The mechanical advantage (MA) of a lever is the ratio of the effort arm length to the resistance arm length. Therefore, MA = Effort Arm / Resistance Arm. In this case, MA = 2.5m / 1.5m = 1.6667.

Since the lever is at 80 percent efficiency, the actual maximum load will be less than the theoretical maximum load. If the effort is 40 N, then theoretically, the lever could lift a load of MA × Effort = 1.6667 × 40 N = 66.667 N. Considering the 80 percent efficiency, the actual maximum load that can be lifted is 0.8 × 66.667 = 53.3 N. Therefore, the correct answer is D. 53.3 N.

Answers

So what the thermal energy equation tells you is the internal heat energy a system gives you due to the movement of particles/temperature. This heat is due to the kinetic energy in the particles. Q represents the heat transfer of a material that has a specific mass, m, specific heat, c, and some temperature or change in temperature, ΔT. For example, say you have an object of mass 1kg, specific heat 0.5J/kg°C and the temperature changes from 50°C to 100°C. To find the heat transfer you would use the equation Q= 1kg*0.5J/kg°C*(100°C-50°C). This would tell you that the heat transfer of this particle is 25J which means that 25J of energy are transferred from one point to the other in this system.
