Answer:
3 x 10^18 kg
Explanation:
Time period, T = 3 days = 86400 x 3 = 259200 seconds
r = 7 x 10^5 m
Let M be the mass of planet
Use the formula of time period of satellite
Where, G be the universal gravitational constant.
By substituting the values
M = 3 x 10^18 kg
Thus , the mass of planet is 3 x 10^18 kg.
Hello! There are four types of non-contact forces I think.
-Gravitational force.
-Magnetic force.
-Electrostatics.
-Nuclear force.
Hope this helps! :)
Answer:
121 N
Explanation:
The component of the weight parallel to the inclined plane is:
mg sin θ
Given mg = 200.2 N and θ = 37.1°:
200.2 sin 37.1°
121
The metallic elements which all react to water are found in the same group, the groups name is the Alkali metals, or also known as group one.
The greater mass the object has the greater its inertia would be. As inertia becomes greater, the same happens with the force which is needed stop motion. Linear motion and rotational motion are quite different, because the first one depends only on mass while the second embraces mass, size and shape of an object. According to the information I shared, one will not be able to stop 10 kg mass due to far greater inertia than object of 1kg mass.
Hope you will find it helpful.
