Heat energy required to change the temperature is given by
here we know that
now from above formula we will have
So it will remove 28255.5 J heat from the water
A. 1.8600 x 105 mi/s
Explanation:
The problem gives us the value of the speed of light in ft/s:
We know the conversion factor between feet and miles:
So we can apply this conversion factor to the speed of light:
Answer:
In animations, usually the sizes of the objects are does not appear to be right because they are made to show the basic features and what's generally happening in the above mentioned case. These inaccuracies are consciously made for the better understanding of the audience. So following are the inaccuracies,
B.The astronaut is too big compared to the moon.
D.The moon is too big compared to its orbit.
F.The moon is too big compared to earth.
Answer:
The speed of the car when load is dropped in it is 10.90 m/s.
Explanation:
Given that,
Mass of the railroad car, m₁ = 11600kg
Mass of the load, m₂ = 5420kg
It can be assumed as the speed of the car, u₁ = 16 m/s
Initially, it is at rest, u₂ = 0
The additional load is dropped onto the car.
Let v is the speed of the car. It can be calculated using the conservation of momentum as :
So, the speed of the car when load is dropped in it is 10.90 m/s.
