What is the difference between the nuclear material in a bomb, versus a reactor? A nuclear reactor works by using the energy that is released when the nucleus of a heavy atom splits. That process is called fission. In reactors, fission occurs when uranium atoms are hit by slow-moving neutrons.
Density is a material property, so the second cube will have the same density as the first.
Explanation:
The given data is as follows.
mass (m) = 0.160 kg, spring constant (k) = 8 n/m,
Maximum speed (
) = 0.350 m/s
Formula for angular frequency is as follows.
= 7.07 rad/sec
(a) Formula to calculate the amplitude is as follows.
A = 
= 
= 0.05 m
Hence, value of amplitude is 0.05 m.
(b) Displacement = 0.030 m
Formula for mechanical energy is as follows.
M.E = 
Putting the values into the above formula as follows.
M.E =
= 
= 
Joule
For x = 0.03,
As, P.E = 
= 
= 
Hence, calculate the kinetic energy as follows.
K.E = M.E - P.E
= ( - ) J
= 
J
Thus, we can conclude that kinetic energy of the puck when the displacement of the glider is 0.0300 m is J.
The question to the above information is;
What is the best use of an atomic model to explain the charge of the particles in Thomson's beams?
Answer;
An atom's smaller negative particles are at a distance from the central positive particles, so the negative particles are easier to remove.
Explanation;
-Atoms are comprised of a nucleus consisting of protons (red) and neutrons (blue). The number of orbiting electrons is the same as the number of protons and is termed the "atomic number" of the element.
J.J. Thomson discovered the electron. Atoms are neutral overall, therefore in Thomson’s ‘plum pudding model’:
- atoms are spheres of positive charge
- electrons are dotted around inside
Answer: temperature of the hot reservoir is 303.52K
Explanation:
Th=temperagture of hot reservoir
Tc=temperature of cold reservoir 263K
Eff=efficiency of the refrigerator
Cop=coefficient of performance
7
Eff=1/cop
Eff=1/7
Eff=0.142
Eff=1-263/th
0.142-1=-263/th
-0.858=-263/th
Th=303.52K
