An explorer in Antarctica leaves his shelter during a whiteout. He takes 40 steps northeast, next 80 steps at 60o north of west,

and then 50 steps due south. Assume all of his steps are equal in length. (a) Sketch, roughly to scale, the three vectors and their resultant. (b) Save the explorer from be-coming hopelessly lost by giving him the displacement, calculated by using the method of components, that will return him to his shelter.

Agata [3.3K]
The potential energy as it reaches a height of 0.63 meters is mgh
Since total mechanical energy is conserved, Set that equal to the initial kinetic energy which is 0.5mv^2

2*9.8*0.63 = 0.5*2*v^2
12.348 = v^2
3.51 = v

That's it's initial speed.

What is the force between two proton’s that are 0.005m apart?
Jet001 [13]

Answer:

Force, F=9.21\times 10^{-24}\ N

Explanation:

Distance between proton is 0.005 m

It is required to find the force between two protons. Protons have of positive charge of 1.6\times 10^{-19}\ C. Two protons will have a force of repulsion between them. The force is given by :

F=\dfrac{kq^2}{r^2}\\\\F=\dfrac{9\times 10^9\times (1.6\times 10^{-19})^2}{(0.005)^2}\\\\F=9.21\times 10^{-24}\ N

So, the force between two protons is 9.21\times 10^{-24}\ N.
