Answer:
Magnets are employed to generate electricity.
Explanation:
Magnets' characteristics are employed to generate electricity. Electrons are pulled and pushed by moving magnetic fields. When you move a magnet around a coil of wire, or a coil of wire around a magnet, the electrons in the wire are pushed out and an electrical current is created.
Answer:
Static friction prevents the motion of an object while sliding friction is a type of frictional motion between two surfaces in contact.
Explanation:
Gravity is the force that pulls us to the surface of the Earth, keeps the planets in orbit around the Sun and causes the formation of planets, stars and galaxies.
Answer:440.03 N
Explanation:
Given
horizontal component of acceleration
vertical component of acceleration
mass of ball =0.37 kg
Force in horizontal direction
Force in vertical direction
Therefore net force is
|F|=440.03 N
We can use Newton's second law to find out. This says F=ma, where m is the mass we seek:
So we see the mass is 3kg
