Question 7 (1 point) A box weighing 43.2 N is pulled horizontally until it slides uniformly (at a constant
speed) over a level floor. The applied force is 6.30 N. Draw a force diagram (FBD)
showing all forces acting on the box. What is the force of friction, in Newtons,
between the box and the floor?

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.
