Answer:
It means that the velocity of the machine is 4
Explanation:
The correct is A.
every magnet have two pole
Answer:
40 000 units of momentum
Explanation:
Assuming that the mass is doubled and the velocity stays constant the new momentum will be doubled the original momentum.
<span>If the thermostat gets too hot, it will turn off the heat an turn on the air conditioner. If a thermostat gets too cool it will turn on the heat or turn off the cold air. The human body is similar to a thermostat because if people get cold, they get covered in goosebumps, if they get too hot they begin to sweat.</span>
Answer:
Distance between two point charges, r = 0.336 meters
Explanation:
Given that,
Charge 1, 
Charge 2, 
Electric potential energy, U = -0.5 J
The electric potential energy at a point r is given by :
r = 0.336 meters
So, the distance between two point charges is 0.336 meters. Hence, this is the required solution.
