Explanation:
Dark Energy. Dark Energy is a hypothetical form of energy that exerts a negative, repulsive pressure, behaving like the opposite of gravity. It has been hypothesised to account for the observational properties of distant type Ia supernovae, which show the universe going through an accelerated period of expansion
4 times as much distance to stop
Answer:
Explanation:
Given
radius of Planet is equal to radius of Earth
Weight of body on Planet 
where m=mass of body
Weight of body on earth 
acceleration due to gravity is given by
where G=gravitational constant
M=mass of Planet
r=radius of planet
for earth 
for planet 
substituting these values in 
and 
divide 1 and 2
Answer:
Yes, in case of uniform velocity
Explanation:
This is the case of uniform velocity. If a body covers equal displacement in equal intervals of time, then the velocity of a body is said to be ‘Uniform Velocity’. It meas that the velocity of a body remains constant during the motion and it does not change.
Since, acceleration is defined as the rate of change of velocity.
Therefore, if there is no change in velocity or in other words the change in velocity is zero, then the acceleration is also zero.
a = ΔV/t = 0/t
a = 0 m/s²
So, the acceleration of the body is 0 m/s², but it has a uniform velocity
<u>Hence, it is possible for an object that, object with zero acceleration have velocity, which is the case case of uniform velocity.</u>
