Answer: the two states that are fluid are;-
<u>#{1} liquid</u>
<u>#{2} gas </u>
Explanation:
as we know that there are mainly three states of substance
but among them only two of them can fluid and takes the shape of the container that are liquid and gas
Answer:
29274.93096 m/s




Explanation:
= Distance at perihelion = 
= Distance at aphelion = 
= Velocity at perihelion = 
= Velocity at aphelion
m = Mass of the Earth = 5.98 × 10²⁴ kg
M = Mass of Sun = 
Here, the angular momentum is conserved

Earth's orbital speed at aphelion is 29274.93096 m/s
Kinetic energy is given by

Kinetic energy at perihelion is 
Potential energy is given by

Potential energy at perihelion is 

Kinetic energy at aphelion is 
Potential energy is given by

Potential energy at aphelion is 
I think this is correct, but I am not entirely certain.
Find the force constant of the spring:
F = - KX
(0 - 62.4) = -K(0.172m)
-362.791 = -K
362.791 N/m = K
Find the work done in stretching the spring:
W = (1/2)KX
W = (1/2)(362.791)(0.172m)
W = 31.2 J
Answer:
The Doppler red-shift of light observed from distant stars and galaxies gives evidence that the universe is expanding (moving away from a central point). This allows for Big Bang Theory, because after a “bang” occurs all of the matter moves away from the point of origin.
