The answer for Plato users is C. It is the energy that is required to overcome mass defect.
From Plato "Nuclear binding energy is the energy that is required to overcome the energy that is used to keep the nucleus together, the mass defect."
Answer:
The average acceleration of the rocket, a = 8.5 m/s²
Explanation:
Given that,
The upward force of the rocket, F = 1700 N
The time duration of rocket exerted the force, t = 8 s
The mass of the rocket, m = 200 Kg
The force exerted by the rocket is equal to the product of its mass and acceleration.
Therefore, the formula for force
<em> F = m x a</em>
a = F / m
Substituting the given values in the above equation
a = 1700 N / 200 Kg
= 8.5 m/s²
Hence, the acceleration of the rocket is, a = 8.5 m/s²
<span>You do these things before a job interview because you want to benefit from primacy effect. Primacy effect refers to the fact that the things that people notice first about other people are likely to be remembered more easily, meaning that first impressions matter. So if you turn up to your job interview in a neat manner, and you are very presentable, you will be more likely to get that job than if you looked like a hobo. </span>
