Which electromagnetic wave transfers the most
energy?
infrared
microwaves
radio waves
Xrays

X-rays

Explanation:

X-rays from the given choices have the most energy and the highest frequency. Think the spectrum as waves on a beach. If the wave lengths are long (radio waves) the waves would hit you more periodically. If the wave lengths are short (gamma rays) they would hit you a lot more and more constantly causing you to fall over because of how much power they are hitting you at. Gamma rays have the shortest wavelengths, which means they have the most energy and highest frequency, where as radiowaves and long, have low energy and low frequency.

the answer is kevlar

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
