Answer:
Ender's mass = 2.25 kg
Explanation:
using law of conservation of momentum .
since there is inelastic collision
given.
At a sudden contraction in a pipe the diameter changes from D1 to D2. The pressure drop, Δp, which develops across the contracti
on is a function of D1 and D2 as well as the velocity, V, in the larger pipe, and the fluid density, rho, and viscosity, μ. Use D1, V, and μ as repeating variables to determine a suitable set of dimensionless parameters. Find how many pi terms are required to describe this problem. Why would it be incorrect to include the velocity in the smaller pipe as an additional variable?

A charged particle moving in a magnetic field experiences a force equal to:
Thus, the magnitude of the force that the proton experiences is given by:
The magnetic field is perpendicular to the proton's velocity, therefore, we have . Replacing the given values, we obtain:
