Answer:
They are able to balance torques due to gravity.
Explanation:
When two friends of different masses will balance themselves on see saw then at equilibrium position the see saw will remain horizontal
This condition will be torque equilibrium position where the see saw will not rotate
Here we can say
here we know that force is due to weight of two friends
and their positions are different with respect to the lever about which see saw is rotating
since both friends are of different weight so they will balance themselves are different positions as per above equation
When a magnet is moved into a coil of wire, changing the magnetic field and magnetic flux through the coil, a voltage will be generated in the coil according to Faraday's Law.
Answer:
Thermal heat
Explanation:
The water heats up which it means it is thermal (heat/hot)
Answer: summer and greater than 66°N
Explanation:
Summer is the most appropriate season in which the sun does not set. It is a typical situation for the Arctic Circle. It is the latitude in which the sun does not set in the day and typically during the month of July. The north of this circle is a period of sunshine which last for a period of about six months in the North Pole. Summer never rises in the winter solstice (December).
Answer:
Work done by the little rocket engine = 19.6 Joules.
Explanation:
We know that work = force x displacement.
Force = weight of rocket = 4.9 N
Displacement = 5 meter.
So work done by the little rocket engine = Weight of rocket x displacement.
Work done by the little rocket engine = 4.9 x 4 = 19.6 J
Work done by the little rocket engine = 19.6 Joules.
