Answer:
The amount of mass that needs to be converted to release that amount of energy is 
Explanation:
From Albert Einstein's Energy equation, we can understand that mass can get converted to energy, using the formula

where
= change in mass
c = speed of light = 
Making m the subject of the formula, we can find the change in mass to be

There fore, the amount of mass that needs to be converted to release that amount of energy is 1.122 X 10 ^-7 kg
Jack Kilby invented the circuit
Answer:
4 m/s²
Explanation:
When the elevator is 1 m below point of contact , compression will be 1 m.
Restoring force in the spring will be 10600 N. Friction force of 17000N will also act in upward direction . The weight of 2000 x 9.8 N will act downwards
Force in down ward direction = 2000 x 9.8
= 19600 N
Force in upward direction
= 10600 + 17000
= 27600 N
Net force in upward direction
= 27600 - 19600
= 8000 N
Acceleration in upward direction
= 8000 / 2000
= 4 m/s²
Well Psychologists are people who are paid to talk to people about their problems or to find out if someone is a danger to themselves or even others. A psychologists investigates the mental state of an individual.
