Answer:
Explanation:
Given
mass of person
=68 kg
car dips about 1.2 cm
We know
F=kx
Where k=combined spring constant
mg=kx
Answer:
B. does it transfer energy
A wave is a disturbance in a medium. Particles vibrate and TRANSFER their ENERGY to their neighbors.
Answer: 4100 Mpc
Explanation:
Since H o = 70 km/s/Mpc
Redshift z = 5.82
Recessional velocity vr = 287,000 km/s
Then, the distance to the galaxy in light years will be:
= Recessional velocity / H o
= 287000 / 70
= 4100 Mpc
Electric generator is a device that converts mechanical energy obtained from an external source into electrical energy as an output. It was discovered that the above flow of electric charges could be induced by moving an electrical conductor such as a wire that contains electric charges in a magnetic field
