If the above object is moving already, and a tension force of 1500 N to the right is pulling it, what will be the NET Force on the object?

How can you increase the strength of an electromagnet?

Arrange the images in order to show how lake-effect snow occurs.

The period of a pendulum varies directly as the square root of the length of the pendulum and inversely as the square root of the acceleration due to gravity. find the period when the length is 144 cm and the acceleration due to gravity is 980 cm per second squared, if the period is 7pi seconds when the length is 289 cm and the acceleration due to gravity is 980 cm per second squared.
