Answer:
98.4 N
Explanation:
Given that the body weighs 800 N on earth.
Thus,
Weight = mass x acceleration due gravity
i.e W = mg
800 = m x 10
m =
= 80 kg
The mass of the body is 80 kg.
To be able to determine its weight on the planet, we have to first calculate the gravitational pull of the planet.
But,
g =
Where: G is the Newton's universal gravitation, M is the mass of the planet and r is the radius of the planet.
g =
=
= 1.2275
g = 1.23 m/
Thus,
Weight of the body on the planet = mg
= 80 x 1.23
= 98.4 N
The weight of the body on the planet is 98.4 N
Hey there!
I believe the answer is A. The boiling temperature did not change
Hope this helps you!
God bless ❤️

Answer:
James Webb has been designed to focus on the infrared part of the spectrum from 0.6 (red light) to 28 microns (infrared). This means it won't be able to see in ultraviolet light like Hubble, but will be able to focus on infrared bright objects like extremely distant galaxies.
Power = energy transfer/ time
During the climb, gravitational potential energy increases.
Increase in potential energy = mass x gravity x height
= 55 x 9.81 x 1.5
= 809.325J
Power = 809.325 / 2
= 404.6625W
Answer:
Value of each charge is given as
Explanation:
As we know that electrostatic force between two charges is given as
here we know that
r = 0.100 m
now we have
