The answer is
Pitch of the buzzer increased (higher tone) as it moves towards the observer
Answer:
14 billion years
Explanation:
The Hubble – Lemaître law, previously called the Hubble law, is a law of physics that states that the redshift of a galaxy is proportional to the distance it is, which is the same as, the further one galaxy is found from another, more quickly it seems to move away from it.
The Hubble constant is the value that measures the rate at which the expansion speed of the Universe varies with distance, and is one of the fundamental parameters of the Universe and allows, in particular, to determine the age of the Universe as we will see.
D-a is the answer can I get braillist
Answer:
This is what you know: Force= 3150N
Distance= 75.5m
This is what you need to find: Work(W)
Use this formula: W=Fd
W= (3150N) × (75.5m)=237,825 Joules (J)
<span>The change in the kinetic energy of the object as the speed changes is proportional to the square of the factor by which the speed changes. For example if the speed of the object becomes double, its kinetic energy changes to four times the initialkinetic energy. Please put brainliest ! :D
