Two point charges of -40.0 x 10^-6 C and 50.0 x 10^-6 C are placed 12.0 cm apart in air. What is the electric field intensity at a point midway between them?
My answer was 2.25 x 10^8 N/C, however, t
What happens when a train traveling at the speed of light turns on its headlights? If they illuminate anything, then wouldnt the light coming from then be going faster than the speed of light? Is it e

Ive been given 3 different cartoon drawings that are meant to be humorous and relate to one of Newtons 3 laws of motion, inertia, definition of force and reciprocity. I was just wondering if somebody
Rennata Gas is driving through town at 25.0 m/s and begins to accelerate at a constant rate of -1.0 m/s2. Eventually Rennata comes to a complete stop.-Vf^2=Vi^2+2adwhere Vf=0, Vi=25m/s, a = -1m/s^2, d
well this is probably a stupid question :$ but is there any difference between gravitational potential energy and potential energy. i am not sure :)
thank you! any answer is appreciated-Gravitational
A stationary trolley of mass 1.0kg is free to move along a frictionless horizontal surface. For the first 10s, a steady horizontal force of 0.5N is applied to the trolly.

Jane walks 400 metres due South, then 250 metres in the direction S85W and finally 180 metres in the direction N20E. Determine the magnitude and direction of her resulting displacement, relative to he
calculate his speed. b) calculate the period of this motion
any help would be appreciated to help solve this practice problem. I am unaware how to begin... thank you!-Use the relationship a = v^2 / R
There are physical events which do not have well-defined causes in the manner of the everyday world. These events belong to a weird branch of scientific inquiry called quantum physics.

For my coursework, there is a transformer in a circuit with only an AC power supply of 20 volts. It has a ratio of 1:1 and the energy is transferred to another circuit. What use or benefits does this
1. Find the Gravitational Force of attraction between a 2200 kg truck and 1100 kg car that are located fifteen meters apart? How large is this force compared to the force of a person pushing a button
Im being an idiot! please help!-1 hour - 3600 s
300km/h = 300000/3600 = 83.33 m/s-1km = 1,000 m
1 hr = 60 min.
60 min. = 60 sec.
convert: 300km x 1000m/1km = 300,000 m1 hr x 60 min./1 hr. x 60 sec./1
