The formula for the functional group is NH2
Answer:
40
Explanation:
because of the force acting on it
Answer:
78.4 J
Explanation:
Given:
Mass of the object (m) = 2.0 kg
Height or displacement of the mass (h) = 4.0 m
Now, change in gravitational potential energy (ΔU) = ?
Change in gravitational potential energy of an object is the energy stored by the object when it is raised to some height above the reference ground level.
Change in gravitational potential energy of an object of mass 'm' raised to a height 'h' above the ground is given as:
Where, 'g' is the acceleration due to gravity and has a value of 9.8 m/s².
Now, plug in all the given values and solve for ΔU. This gives,
Therefore, the change in gravitational potential energy is 78.4 J.

.
As the radius of the earth's very nearly circular orbit around the sun is 1.5 x 10^11 m.
Therefore, the magnitude of the earth's velocity
.
The magnitude of the earth's angular velocity is
