Answer:
E = 1.45 x 10⁹ J = 1.45 GJ
Explanation:
According to the law of conservation of energy:
Potential Energy Lost by Satellite = Kinetic Energy + Internal Energy
where,
E = Internal Energy = ?
m = mass = 400 kg
g = acceleration due to gravity = 9.81 m/s²
h = height = 500 km = 500000 m
v = speed on ground = 1.6 km/s = 1600 m/s
Therefore,
<u>E = 1.45 x 10⁹ J = 1.45 GJ</u>
Answer:
Explanation:
We have given mass m=0.155 kg
Force constant K = 305 N/m
Distance 
Velocity 
The total energy at any position of the motion is give by 
here 
is energy due to motion and 
is energy due to spring elongation
So total energy 
Answer:
1.4 s
Explanation:
Given the following data;
Quantity of charge, Q = 2.5 C
Current = 1.8 A
To find the time required;
Mathematically, the quantity of charge passing through a conductor is given by the formula;
Quantity of charge, Q = current * time
Substituting into the formula, we have;
2.5 = 1.8 * time
Time = 2.5/1.8
Time = 1.4 s
Yes they are balanced because if it has 10 Newtons to the right and then someone pushes 5 Newtons to the left and then another 5 then that means there is 10 Newtons left and 10 Newtons right
