Answer:
the Power required is 300 W
Explanation:
We know that the definition of work is given by the following expresion:

the distance is 1.5 meters and the Force is equal to 1000 N.
Replacing this values in the work expresion

And the power is equal to the amount of work done in a given time, therefore we have:

Time in seconds

Answer:
D. 75 watts

brainliest please? i've just answered 3 of your questions and they were all correct! :) i hope i helped!
The change in internal energy of the gas is

.
In fact, the 1st law of thermodynamics states that the change in internal energy of a system is equal to the amount of heat given to the system (Q) plus the work done on the system (W):

In this example, no work is done on the bottle so W=0, while the heat given to the system is

, so the change in internal energy of the gas is
Explanation:
Given that,
(a) Frequency, 
All electromagnetic wave moves with the speed of light. It is given by :


(b) Frequency, 
All electromagnetic wave moves with the speed of light. It is given by :


Hence, this is the required solution.
