Answer:
Explanation:
The troposphere is hotter near the Earth's surface because heat from the Earth warms this air. ... Mesosphere: As the altitude increases, the air temperature decreases. The Mesosphere, like the troposphere layer, has a decrease in temperature with altitude because of the decreases in the density of the air molecules.
when current is reversed in the direction the force due to magnetic field is also reversed
As we know that the formula of force will be given as
so here if the direction of current is reversed the the force vector also reverse its direction
So we will have the direction of force is also reverse and it will move downwards now
Answer:
29 m/s
Explanation:
Acceleration is the rate of change of velocity, i.e, the change in velocity per unit time.
The driver made the car to accelerate at 3 m/s^2. That means than in every second the velocity of the car increased by 3 m/s. Therefore in four seconds its velocity would increase by 3m/s x 4 = 12m/s. Starting with an initial velocity of 17 m/s the final velocity would be 17 m/s + 12 m/s = 29 m/s.
Answer:
Explanation:
give data:
inside diameter = 5.0 cm
charge q = 0.25 nC
Outside diameter = 15 cm
potential V at inside sphere is =
potential V at outside sphere is =
k is constant whose value is =
then potential difference between two point is
