Sun fives off both of them
Answer:
Q = 116.8 J
Explanation:
Here given that the temperature of 1 L hydrogen is increased by 90 degree C at constant pressure condition.
So here we will have
here we know that
n = number of moles
for ideal diatomic gas molar specific heat capacity at constant pressure is given as
now we have
Answer:
This question is incomplete, a possible question would be to calculate the work done by the ball.
Work done = 8J
Explanation:
Work done by an object is calculated my multiplying the force by the distance.
The weight of this ball is 2.0N, which also represents the force exerted by the ball. The ball travels through a distance of 4m
Hence, work done = F × d
Work done = 2N × 4m
Work done = 8Nm or 8J
Answer: 226.2 m
Explanation:
If we want to find the new total height 
of the building, we have to add to its initial height 
the height of the antenna 
, as follows:
Then:
This is the new total height of the building.
3. Distance is a quantity that is always a vector.
B.
