Answer:
decibel gain is 10 db
Explanation:
given data
voltage v1 = 5 volts
voltage v2 = 15 volts
to find out
decibel gain
solution
we have given that 5 volt voltage that is increase to 15 volts
so
we know here decibel gain formula that is
decibel gain = 20 log(v2/v1) ....................1
put here value of v1 and v2 in equation 1
decibel gain = 20 log(15/5)
decibel gain = 20 log3
decibel gain = 20 × 0.4771
decibel gain = 9.54 db = approx 10 db
so decibel gain is 10 db
Answer:
1. Walking
2. Pushing the basketball with hand
3. Ball bouncing off the ground
Explanation:
As per Newton's third law of motion every action has an equal and opposite reaction. Looking at the given scenario following are the pairs of action-reaction forces:
1. Walking: When you walk, you apply action and push the ground and the ground pushes you back with the same force.
2. Pushing the basketball with hand: when you push the ball that is action, the ball also applies force on your hand which is the reaction.
3. Ball bouncing off the ground: When ball hits the ground, it applies force i.e. action and the ground pushes it back with the same force which is the reaction.
Answer:
anabolism
Explanation:
Anabolic processes are basically construction, growth or synthesis processes, in which large molecules are obtained from other smaller molecules.
Through anabolic processes, molecules that form new cells are obtained. During these construction processes, a large amount of energy is consumed, for example, through protein building reactions, from amino acids. Anabolism is the metabolic process responsible for the formation of cellular components, muscle tissues and, therefore, growth.
