Answer:
A. it will move faster than the large object was moving initially
Answer:
.c. −160°C
Explanation:
In the whole process one kg of water at 0°C loses heat to form one kg of ice and heat lost by them is taken up by ice at −160°C . Now see whether heat lost is equal to heat gained or not.
heat lost by 1 kg of water at 0°C
= mass x latent heat
= 1 x 80000 cals
= 80000 cals
heat gained by ice at −160°C to form ice at 0°C
= mass x specific heat of ice x rise in temperature
= 1 x .5 x 1000 x 160
= 80000 cals
so , heat lost = heat gained.
We know that 20 m/s N is a vector quantity because N in the expression signifies the direction
<h3>What is a vector quantity?</h3>
This is a which have both magnitude and direction. Example include:
- Velocity
- Displacement
- Force
- Acceleration
- Moment
- Weight
<h3>How to determine whether 20 m/s N is a vector quantity</h3>
- 20 m/s indicates just the speed i.e magnitude
- 20 m/s N indicates the speed i.e magnitude why the N indicates the direction.
Thus, we can conclude that 20 m/s N is a vector quantity because it has both magnitude and direction.
