Who created E = mc2? (What is it)?

1 answer:

5 0

Albert Einstein created this equation. It means that the formula $E= mc^{2}$ shows that mass can be converted into energy, and energy can be converted into mass. Einstein made this equation 100+ years ago, and yes, he was right with the theory.

(Mark this as the brainliest if this answer helps!)

The only two forces acting on a body have magnitudes of 20 N and 35 N and directions that differ by 80°. The resulting accelerat

pantera1 [17]

Answer:

b) 2.2 kg

Explanation:

Net force acting on an object is the sum of the two forces acting on the body.

The net force is calculated using the parallelogram law of vectors.

F = $\sqrt{{A^{2}} + B^{2}+2 A B cos \theta}$

Here A = 20 N , B = 35 N and θ =80°

Net Force = F = 43.22 N

Acceleration = a = 20 m/s/s

Since F = ma, m = F/a = 43.22 / 20 = 2.161 kg = 2.2 kg

If you borrow your mom's car to drive 128 m to the store, but you go cruising

valina [46]

Answer:

v = 0.349 m/s

Explanation:

If you borrow your mom's car to drive 128 m to the store, but you go cruising instead and drive a total distance of 1256 m in 3600s.

We need to find your speed during the trip. It is equal to the total distance divided by time taken.

He has done cruising instead and drive a total distance of 1256 m.

So,

$v=\dfrac{d}{t}\\\\v=\dfrac{1256\ m}{3600\ s}\\\\v=0.349\ m/s$

So, the speed of the person during the trip is 0.349 m/s.

aleksklad [387]

Answer:

open source Software

Explanation:

An open source software can be any software made available within an open source license which means that anyone can access its source code, see that it was created and, as the question says, "study, change and improve it."

This is contrary to copyrighted or closed source software where you would require a license to use the software, however, we can not see or amend in the "building blocks" (i.e. code)

If an object of mass 6 kg has an acceleratoon of 9 m/s2, what is the unbalanced force acting on it?

Nikitich [7]

So long as an object is accelerating, it means there is an unbalanced force acting on it.

Force = mass * acceleration
F = ma
F = (6)(9)
F = 54N
