Answer:
Increase the temperature of juice in Glass A by 20 °C
Answer:
1200N
Explanation:
Suppose a body of mass "m" and its weight on the moon is Wm (where W is the weight and "m" is the moon ;which means weight on the moon).Mass of the moon is "M"
and its radius is "R"
Weight of an object on the moon = "F"(Force)with which the moon pulls.
Wm = GM*m/r2
Weight of the same object on the earth is We(where W is the weight and "e" is the earth; which means weight on the earth).
Mass of the earth is 100 times of that of the moon.
Radius of the moon = R
Radius of the Earth = 4R
Weight of the object on the moon =
We = G100M*m/(4R)2(Pronounced 4 R square)
We = G100M*m/(16R)2(Pronounced 16 R square)
Wm/We = G * M * m * 16R2/R2 * g * 100M * m
=16/100
Therefore, 4800N on earth= 1200N on moon
Answer:
18 m
Explanation:
G = Gravitational constant
m = Mass of planet =
= Density of planet
V = Volume of planet assuming it is a sphere =
r = Radius of planet
Acceleration due to gravity on a planet is given by
So,
Density of other planet =
Radius of other planet =
Since the person is jumping up the acceleration due to gravity will be negative.
From kinematic equations we have
On the other planet
The man can jump a height of 18 m on the other planet.
