Answer:
6.86 N
Explanation:
Applying,
F = mg............... Equation 1
Where F = Force exerted by gravity on the mass, m = mass, g = acceleration due to gravity
Note: The Force exerted by gravity on the mass is thesame as the weight of the body.
From the question,
Given: m = 700 g = (700/1000) = 0.7 kg
Constant: g = 9.8 m/s²
Substitute these values into equation 1
F = 9.8(0.7)
F = 6.86 N

The skier's speed at time <em>t</em> is
<em>v</em> = (23 m/s²) <em>t</em>
To reach a speed of 9.3 m/s, the skier would need
9.3 m/s = (23 m/s²) <em>t</em>
<em>t</em> = (9.3 m/s) / (23 m/s²)
<em>t</em> ≈ 0.404 s
Answer: A. The total number of protons and the total number of neutrons both remain the same.
Explanation:
Nuclear fission is the process in which a large nucleus splits into two smaller nuclei with the release of energy. In other words, fission is the process in which a nucleus is divided into two or more fragments, and neutrons and energy are released.
