Answer:
1) Energy transfer is the movement of energy from one location to another. ... Energy transformation is when energy changes from one form to another – like in a hydroelectric dam that transforms the kinetic energy of water into electrical energy.
2)A swinging pirate ship ride at a theme park. Kinetic energy is transferred into gravitational potential energy.
A boat being accelerated by the force of the engine. ...
Bringing water to the boil in an electric kettle.
3)Common examples of energy storage are the rechargeable battery, which stores chemical energy readily convertible to electricity to operate a mobile phone, the hydroelectric dam, which stores energy in a reservoir as gravitational potential energy, and ice storage tanks, which store ice frozen by cheaper energy at night
Explanation:
PLEASE MARK ME AS BRAINLIEST
To solve the exercise it is necessary to apply the concepts given in Newton's second law and the equations of motion description.
Let's start by defining acceleration based on speed and time, that is
On the other hand according to Newton's second law we have to
F=ma
where
m= Mass
a = Acceleration
Replacing the value of acceleration in this equation we have
Substituting with our values we have
Re-arrange to find v
Therefore the speed of the glider is 2m/s
Answer:
This is the answer
Explanation:
You can find the ans in the photo I attached.
Electromagnetic waves don't require a medium to travel.
The waves would combine to form a wave with a displacement equal to the sum of the two initial waves. This is called constructive inteference.
