The state of the atmosphere at a given place and time as regards to heat, dryness sunshine, wind, rain, etc.
Answer
given,
mass of raindrop = 5.4 × 10⁻⁷ kg
acceleration due to gravity = 9.8 m/s²
a) magnitude of gravitational force on the rain drop
Force on the rain drop = m g
Force on the rain drop = 5.4 × 10⁻⁷ x 9.8
= 5.292 x 10⁻⁶ N
Hence, force on raindrop by earth is equal to 5.292 x 10⁻⁶ N
b) by newtons third law
Force by the earth on the raindrop will be opposite to the force by raindrop on earth.
Force on earth by raindrop = - 5.292 x 10⁻⁶ N
negative sign represent that force is acting in the opposite direction.
answer
6000 N
explanation
every force has an equal and opposite reaction force, so the force exerted by the truck on the car is the same as the force exerted by the car on truck
the force is 6000 N
