Answer:
The correct answer for this problem is conduction.
Explanation:
I just did the test and conduction was the correct answe.
Answer:
Time taken, t = 2.37 seconds
Explanation:
It is given that,
Height of an object at time t is given by :
Where
v₀ is initial velocity of object
h₀ is initial height of the object
The feather is dropped from the top of the bridge 90 feet above a river. we have to find the time taken by the feather to reach the water.
At the surface of water, h(t) = 0 and v₀t = 0
So,
t = 2.37 seconds
The feather will take 2.37 seconds to reach the water surface.
Answer:
Explanation:
We know that,
Where m is mass and v is velocity or speed.
Putting the required values,
divide both side by 144
So the mass of the diver is 70 kg respectively.
