Answer:
A. Kinetic energies are equal.
Explanation:
The kinetic energy of the bodies will be equal since the mass and speed are the same.
Kinetic energy is the energy due to the motion of a body.
Mathematically;
K.E = m v²
m is the mass
v is the speed
The kinetic energy is a scalar quantity with no regard for direction.
Answer: If i'm not mistaken I think it A) potential
The equation for calculating the Work is very simple that is Work=Force x Displacement. We have a Force given as 209N and displacement = 10 meter.
Putting these values directly in the formula gives us Work = 209N x 10m
Work = 2090 Joule.

What is an agn outburst
?</h3>
An active galactic nucleus (AGN) is a compact area at the core of a galaxy with much higher-than-normal brightness throughout at least some section of the electromagnetic spectrum and features indicating that the luminosity is not created by stars. Excessive non-stellar emission has been reported in radio, microwave, infrared, optical, ultra-violet, X-ray, and gamma ray wavebands. The non-stellar radiation emitted by an AGN is thought to be the product of matter accretion by a supermassive black hole at the heart of its host galaxy.
Active galactic nuclei are the most brilliant and enduring sources of electromagnetic radiation in the cosmos, and as such, they may be utilised to find faraway objects.
