The system schema goes person<string<cart

Then beneth that place earth and dram arrows pointing at person and cart because they r the only ones touching the earth. I do not know what the force diagram would look like so please dont ask

The lesser the mass, the greater the acceleration for the given value of force. Why does this happen?

Tju [1.3M]

Newtons law states F=ma
so F/m=a
in addition it makes logical sense the lighter an object the easier it is to accelerate its velocity form 0 to some quantity

The radioactive isotope U-238 has protons and neutrons.

Archy [21]

Answer:

92 protons, 146 neutrons

Explanation:

Uranium will always have the same amount of protons, because that is what defines the element. Uranium has 92 protons, meaning that the rest of the mass of the atom comes from neutrons. 238-92=146 neutrons. Hope this helps!

Answer:

$v=3.47m/s$

Explanation:

The speed is by definition the distance traveled divided over the time it takes to travel that distance. In this case, this distance is the circumference of the wheel, so we have:

$v=\frac{C}{t}=\frac{2\pi r}{t}$
