Transfer of Energy from the Ocean to the Atmosphere
When air in contact with the ocean is at a different temperature than the sea surface, heat transfer by conduction takes place. The ocean also absorbs and stores energy from the sun, and when precipitation falls, it releases heat energy into the atmosphere.
So i would say the answer is true :)
Answer:
correct option is d) 7.0 x 10^-7 N
Explanation:
given data
distance = 175 picometers = 1.75 × m
to find out
electrical force
solution
we know atomic no of uranium is 92
and charge on electron is = 1.6 × C
and electrical force is express as
electrical force = .............1
put here value we get
electrical force =
electrical force = 6.921 × N
so correct option is d) 7.0 x 10^-7 N
A, and D are two correct answers im not sure about the third sorry
mass lol ion kno man can i have the answer choices
The velocity of the combined mass after the collision is 0.84 ms-1.
<u>Explanation:</u>
According to law of conservation of momentum, the change in momentum before collision will be equal to the change in momentum of the objects after collision in isolated system.
But as it is perfectly inelastic collision in the present case, the final momentum will be based on the product of total mass of both the object with the velocity with which the collision occurred. This form is attained from the law of conservation of momentum as shown below:
So as law of conservation of momentum,
Here = 3 kg and = 2 kg are the masses of objects 1 and 2, = 1.4 m/s and = 0 are the initial velocities of object 1 and object 2, and are the final velocities of the objects.
So after collision, object 1 get sticked to object 2 and move together with equal velocity = = . Thus the above equation will become,
So the final velocity is
Thus,
= 0.84 ms-1.
