Need the solutions to the problem. I was able to get an answer of: Velocity (B) = 7.8m/s ---> Q= 245L/s however when i tried to get the Pressure at summit, I get the wrong answer can someone please ...

I dont understand how to do the question I attached.

if you brought a negatively charged balloon near a plastic water bottle would it be attracted or repelled

Three identical charges q = -1 nC are placed in the xy- plane at coordinates (-1, 0), (1, 0) and (0, 1). Find the work needed to move the last charge in the list to (a) a new position (0, 0) and (b) infin ...

A loop is formed by two parallel conductors connected by a solenoid with inductance L and a connecting rod of mass m which can freely (without friction) slide over the conductors. The conductors are located in ...

What can the structure of of a skeleton tell us about the relationship between organisms?

1 You start pushing a 5 kg block from rest on a horizontal surface with a horizontal force of 40 N. If the friction has a friction coefficient of u = 0.2, how much movement energy does the block get when you p ...

Supposed instead of giving the mass an initial displacement of 5cm you gave it 10cm. How would this affect the period of oscillation and frequency of the oscillating system.

A student drops a rock from a bridge to the water 12.4 m below. With what speed does the rock strike the water? The acceleration of gravity is 9.8 m/s^2 . Answer in units of m/s

A 40-N crate rests on a rough horizontal floor. A 12-N horizontal force is then applied to it. If the coefficients of friction are μs = 0.5 and μk = 0.4, the magnitude of the frictional force on the crate is

Why two vectors cannot be divide? Explain and give a reasonable example

on a frictionless surface. a boy pushes a girl, causing a girl to accelerate at 3.2 m/s to the right. mb= 72 kg; mg=63 kg. find F exerted by boy on girl and F exerted by girl on boy. Find the acceleration of th ...
