In order to see what the problem is, I will attempt to find this speed. 350keV=5.6110^-14 J E_k=1/2 * mv² =>  v=sqrt(2E_k/m) By plugging in numbers, we...

Humans have a logarithmic perception of the majority of uncountable and some countable things. A₀, which is percieved as the basic note, has a frequency of 27.50 Hz. A₁=55 Hz, and A<...

Since we are neglecting air resistance the energy of the ball is conserved. We set the gravitational potential energy to be U=0 at h=0. Applying conservation of energy at h=0 and h=h_max , we ge...

Apparatus: The wire is secured by a clamp and clamp stand A hanging mass is attached to the end of it, where the mass hung can...

Let's begin with the definition of stress:

Stress = F/A

First, we need to recall that the force the weight of the crate will exert on the cable will be equal to:

F= m*g

We know...
