Answer:
There is no force in space.
Explanation:
Weight is the gravitational force acting on the mass as in space there is no gravity so weight appeares as zero
Hello,
Here is your answer:
The proper answer to this question is that you find the velocity by "you have to divide the distance by time of the object".
If you need anymore help feel free to ask me!
Hope this helps!
Answer:
Power = 2940 Watts
Explanation:
Given the following data;
Mass = 60 kg
Height = 300 meters
Time = 1 minutes = 60 seconds
To find the power;
First of all, we would determine the potential energy possessed by the person due to height.
We know that acceleration due to gravity is equal to 9.8 m/s².
Potential energy can be defined as an energy possessed by an object or body due to its position.
Mathematically, potential energy is given by the formula;
Where,
P.E represents potential energy measured in Joules.
m represents the mass of an object.
g represents acceleration due to gravity measured in meters per seconds square.
h represents the height measured in meters.
Substituting into the formula, we have;
P.E = 60 * 9.8 * 300
P.E = 176400
Next, we find the power using the following formula;
Power = energy/time
Power = 176400/60
Power = 2940 Watts
Explanation:
It is given that,
Let are the masses of two objects such that,
............(1)
Force between them,
Distance between masses, d = 19 cm = 0.19 m
The gravitational force between two masses is given by :
.............(2)
On solving equation (1) and (2),
Mass of heavier object,
Mass of lighter object,
Hence, this is the required solution.
