Opposite Poles in Magnets Attract Each-other
Answer:
Explanation:
the resistance of a electrical device
R = V² / P where V is volt and P is power .
The devices are in parallel so same volt will apply on them
So R₁ = 12² / 32.5 = 4.431 ohm
R₂ = 12² / 2 x 10³ = .072 ohm
when they are in series
Common Current in them = 12 / 4.431 + .072
= 2.6649 A
power consumed by first device when they are in series
= current² x resistance
= 2.6649² x 4.431 = 31.46 W
power consumed by other
= 2.6649² x .072 = .511 W
The correct explanation for the process of formation of dew from the water vapour is The water releases energy which causes the water molecules to have less kinetic and potential energy, changing their configuration from gas to liquid.
vapour is a gaseous form, while dew is a liquid state of matter therefore it's clear that vapour has to release energy to come in the liquid state, and in this process vapour, water molecules lose their kinetic and potential energy.
Answer
given,
mass of car = 800 kg
mass of truck = 1900 kg
force acting = 4900 N
a) F = (m₁+ m₂ ) a
a = 1.815 m/s²
a) force exerted by the car on the truck
F = 3448.5 N
b) According to newtons third law
Force exerted by the truck on the car will be same.
Force of the truck on the car = F = 3448.5 N
