The big bang theory describes and claims that the universe has been created through cosmic expansion originating from a single point.
Where it was explained that the nature of now objects in space being in constant space was due to once a high density and high density point produce a scattering or explosion of the cosmic energy . Other theories have also supported this theory originally and first documented by Georges Henri Joseph Édouard Lemaître an astronomer and physicist.
It would be true. Excess radiation causes cancer.
Answer:
The second one
Explanation:
It caused both to change speed because they have both the same mass.
Answer:
(a) 0.061 m/s
(b) 0.103 m/s
Explanation:
From the law of conservation of momentum, the sum of initial momentum equals the sum of final momentum
Momentum, p=mv where m is the mass and v is the velocity
where 
is the common velocity, 
is the velocity of the ball 
and 
are masses of the ball and person respectively
Substituting the given values then
(b)
Momentum, p=mv where m is the mass and v is the velocity
is the velocity of the ball , 
is the velocity of ball afterwards and 
is your speed, and are masses of the ball and person respectively. Since it bounces back, we give it a negative value hence
