Explanation:
Solids have a definite shape and definite volume.
Length of the copper rod = 2.5 meters
Speed at which sound travels through copper = 3560 meter per second
Let us assume the time taken
by sound to cover the given distance = x seconds
We already know that
Speed = Distance/ Time
Then
Time = Distance/ Speed
x = 2.5/3560 seconds
= 0.0007 seconds.
This can ve done by hitting one end of the rod and then receiving the sound at the other end and using the stop clock to measure the time taken.
Answer:
he electron is directly transferred to NADP+ to NADPH, but electron flow is used to generate a proton gradient for ATP synthesis. Electron is not directly transferred to ATP
NADP= Nicotin amide adenine dinucleotide phosphate
NADPH =Nicotinamide adenine dinucleotide phosphate is the reduced form of NADP
therefore electron is not directly transferred to ATP
