Explanation:
(9) Acceleration due to gravity is defined as the acceleration between two massive bodies when they are moving under free fall.
The relation between g and G is given by :

Where
G is universal gravitational constant
M is mass of the earth
r is distance
(10) The unwanted product that can toxify the crops are called weeds. To control weeds, a chemical called weedicides are sprayed in the field. Some other methods to control them are Ploughing or tilling of soil etc.

Answer:
Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement.
We need to subtract his current status by his goal:
goal - current = needed
6.12 - 5.73 = 0.39 m.
Now, we need to convert to cm. Since there is 100 cm in 1 m:
0.39 * 100
39 cm
Hope this helps!
Answer:
Electric potential, 
Explanation:
It is given that,
The magnitude of electric field, 
Distance between automobile engines that consists of metal conductors, 
Let V is the magnitude of the potential difference between the conductors. The relation between the electric field and the electric potential is given by:



So, the magnitude of the potential difference between the conductors is
. Hence, this is the required solution.
