The diagram should show a negative point charge with the electric field lines pointing towards the point charge. The separation of the lines should decrease as you get closer to the point charge. The line...

The centripetal acceleration is the acceleration a body experiences in centripetal motion (moving in a circle or along an arc). Centripetal acceleration always points towards the centre of the circle, hen...

(Lets consider a simple planetary system composed of a planet orbiting a star. the gravitational force between the two is given by F=(GMm)/(r²). Assuming the planet also moves in a circular orb...

Waves that go up and down in a curvy shape like you would draw on a piece of paper are called transverse waves. Scientifically, these are when the particles move in a direction that is perpendicular (90) ...

Stress = Force/Area and cross sectional area of a cyclinder = pi.r²
As diameter = 10.0cm=0.1m r=0.05m so area = 3.14*0.05² = 0.00785m²
As the force is 50.0N the...
