How many stairs?
You can use this to find the work
U
W=mgh
And the power by
P=W/T
Probably 90 j but im not sure I haven’t done any work like this in a while
As per Newton's III law we can say that
Force applied by object 1 on object 2 is always equal in magnitude and opposite in direction of the force that object 2 apply on object 1.
So we can say it as
now here above question is based upon the same
if a bag of vegetables applied a force F = 22.5 N of the surface stand the the same surface will apply same magnitude of force in opposite direction on the vegetables bag
So our answer will be F = 22.5 N (upwards).
Answer:
Explanation:
Altitude of the Sun and the latitude position on the earth play an important role in the season change on the earth.
When the altitude of the sun is high then the average temperature of the earth is higher because the luminous intensity of the sun rays is higher due to the focusing of high energy sun rays over a small area.
But when the sun is at higher altitudes we receive less denser rays of the sun and hence we have less heat on the earth on an average.
- But despite of the altitude some places on the earth have distinct temperature than the other place at the same time of the year. This is due to their latitudinal location. The places near the equator are warmer most of the times throughout the year because they receive the most direct rays while the poles receive slanting rays and hence are colder even in summer when the earth is at lower altitudes.
