Answer:
The net force should be of a magnitude of 64 N
Explanation:
We use Newton's second Law for this:
which for our case gives:
Answer:
Weight measurement at poles will be slightly more than at equator.
Explanation:
Firstly earth bulges at equator. This makes the body far from earth center at equator than poles. Secondly, the surface centrifugal forces of earth due to rotation also plays vital role in disturbing the gravity value. The centrifugal forces cancel the effect of gravity more at equator than at poles.These factors combine to create difference of about 0.5% in gravity values at pole and equator.
gravity at pole=9.832 m/s^2
gravity at equator=9.780 m/s^2
The flux will be 4 times stronger ( due to the inverse square law )
Answer
The image formed by a concave mirror will be virtual, erect and magnified when the object is placed only between the pole and the principal focus of the mirror.
Hope it helped u if yes mark me brainliest!
Tysm!
The pressure in a liquid at a given depth is called the hydrostatic pressure. This can be calculated using the hydrostatic equation:
P = ρgh
P = (1000 kg/m³)(9.8 m/s²)(4 m)
<h2>
P = 39200 Pa</h2>
