Hedea made a study chart about nuclear energy. Which best describes the error in Hedea’s chart? The nuclei of atoms are split ap

art in both fission and fusion. The nuclei of atoms are joined together in both fission and fusion. Fission converts nuclear energy to electrical energy, not thermal energy. Fission and fusion convert nuclear energy to both radiant and thermal energy.

Option (d) is correct.Fission and fusion convert nuclear energy to both radiant and thermal energy.

fission is a process in which bigger nucleus breaks into two or more smaller nuclei with the liberation of a large amount of energy.

Fusion is a process in which two small nuclei fuse together to from an intermediate size nucleus with the liberation of tremendous amount of energy

During fission and fusion, energy is released in the form of both light (radiation) and heat.we can then convert that energy into useful form.

13. An object with a mass of 2.0 kg has a force of 4.0 newtons applied to it.
julsineya [31]

Answer:2m/s²

Explanation: Well F=MA so sice F=4N and M=2kg let's plug in the values

4N=2KG*A

A=4N/2KG

A=2m/s²

If a car races around a 2.3 mile oval track 220 times, what is the displacement of the car in meters when it crosses the finish
Wewaii [24]

Answer: 0 miles.

Explanation:

First let's define what the displacement is:

The displacement is defined as the difference between the final position and the initial position.

So, if for example, you start at your house, then go to a store, and then go back to your house, your total displacement will be zero, because the initial position and the final position are the same.

Then when the car reaches the final line, it will be in the same place that it started (because this is an oval track, so the finish line connects with the starting point)

Then the total displacement is 0miles.

A swift moving hawk is moving due west with a speed of 30 m/s; 5.0 s later it is moving due north with a speed of 20 m/s.
vaieri [72.5K]

Answer:

See explanation

Explanation:

Now we have;

vi = (-30, 0) m/s

vf = (0, 20) m/s

Δvav= vf - vi= (30, 20) m/s

magnitude of Δvav= √30^2 + 20^2 = 36.0 m/s

Direction = tan-1(20/30) = 33.69°

For aav

aav= Δvav/t = (30/5, 20/5) = (6,4) m/s^2

magnitude of  aav = √6^2 + 4^2 = 7.2 m/s^2

direction of aav = tan-1(4/6) = 33.69°

An individual is nearsighted; his near point is 13.0 cm and his far point is 50.4 cm. what lens power is needed to correct his n
Colt1911 [192]

Answer:

= -1.984 Diopters

Explanation:

The lens should form an upright, virtual image at the far point.

Therefore;

The image distance, V will be -50.4 cm, since the image is virtual.

For objects at very far distant the object distance,u, will be ∞ ; This means that focal length, f, will be equivalent to image distance, v, that is -50.4 cm

Therefore; f = -50.4/100 = -0.504 m

But, since Power of a lens, P, is given by the reciprocal of focal length in meters, (1/f)

Then, power will be given by;

Power = 1/f

           = 1/-0.504 m

           =- 1.984

Power is measured in Diopters

Hence          <u>= -1.984 Diopters</u>
