B, heat, is the correct answer. Heat is represented by a capital q in thermodynamic equations.
70kg
1 earth gravity
80 M of height

54917.2 Joules of energy
Mrs. Stark has 54,917.2 Joules of energy.
Ground state, since electrons want to be in the lowest energy position as possible, which is closer to the nucleus of the atom.
Answer:
(A) it's acceleration is negative but but it's velocity is positive
Explanation:
In the question it is given that begins to slow down so its speed is decreasing it is does not means that its speed is negative
For example let first the velocity of the car is 30 m/sec and when its velocity decreases it becomes 20 m/sec in 5 sec
So it is not negative at all
Now the acceleration is the rate of change of velocity


So acceleration is negative here
So option (a) will be the correct option
If you are given time and distance, you can determine power if you know
force. watts. energy. joules.
Answer is joules.
Power is defined as the rate of
doing work. Hence power = work / time then you obtain watts. Work is the
product of force and displacement (distance). Hence in formula, w = F x s. In
which the S.I unit of work is joule in the product. This is what you have to
obtain in order to calculate for power.
