Suppose the ice caps at the South and North poles melted due to the global warming and the water was distributed uniformly over

the earth's oceans. Would the earth angular velocity increase, decrease, or remain the same? Would each day get shorted or longer as compared to the current days? Explain.

Answer:

Explanation:

The Earth rotates about its axis once a day. Instead, the rate of rotation varies by up to a millisecond per day. The speed of the Earth’s rotation will increase if its mass is brought closer to its axis of rotation, that is net movement of mass. Conversely, the speed of the Earth’s rotation will decrease if its mass is moved away from the rotation axis.

Yes the days would be longer. Since the ice that was at the South Pole is now distributed around the world, there is a change in the distribution of mass.

As an object falls freely near the surface of the earth, its velocity?
Vsevolod [243]

If it were possible for an object to fall freely near the surface of the Earth,

-- The direction of its velocity would always be "down"; that is, toward the center of the Earth.

-- The size of its velocity would continually increase, at the rate of 9.8 meters per second for every second it falls.

A circuit has an overall resistance of 40 ohms and a current of 200mA.
svetoff [14.1K]

Answer:

Hey!

_________________

Voltage (V) = 0.8V

Current (I) = 200 mA = 200/10^3 = 2/10

Resistance = ?

Resistance = Voltage / Current

Voltage = Current × Resistance

0.8 = 2/10 × Resistance

0.8×10/2 = Resistance

8/2 = Resistance

Resistance = 4 ohm

If BHALA AHMAD KHAN applied the 20N force is applied on an object moving with the velocity 30 m/s. calculate the power in KW.
Leokris [45]

Answer:0.6kw

Explanation:

Power=force×velocity

Power=20×30=600w

In kw it's going to be 600/1000=0.6kw
