If the radius of a star increases by a factor of 6 the surface area of the star increases how many times?
1 answer:
Answer:
When radius of star increase by 6 factor then area of star will increase by a factor of 36.
Explanation:
As we know that
Area of star A given as
Where R is the radius of star.
Area of star when radius become 6 times
So
We can say that when radius of star increase by 6 factor then area of star will increase by a factor of 36.

Answer:
Explanation:
Given:
force applied,
displacement caused,
<u>Work done by the force on the cart:</u>
Negative work means that the force and displacement have an obtuse angle between them.
P = m/v
6000 kg/m3 = m/4x10^-4
m = 2.4 kg
P = m/v
5000 kg/m3 = 2.4kg/v
V = 4.8 x 10^-4
0.7N x 10 = 7kg
P = m/v
P = 7/4.8 x 10^-4
P answer = 1458.3
It is right?
It takes sunlight 8 minutes to reach earth , so yes
work done = force * distance moved (in direction of the force)
force= mass* acceleration
force=58.1N
58.1*(5.8*10^4)
=3,369,800 J
