What is the basic functions of the blood in the cardiovascular system

A pulley system used to lift car tires has a mechanical advantage of 8.1. If you pull on the pulley with a force of 540 N, how much force does the pulley exert on the tire?

A force of 25N pushes an object at an angle of mass 50kg at an angle 40 degrees to the horizontal. Calculate the coefficient of friction

Without Newton's third law of motion, what would an object sitting on a table do?

A particle moves along the x axis. It is intially at the position 0.270 m, moving with velocity 0.140 m/s and acceleration - 0.320 m/s^2. Suppose it moves as a particle under constant acceleration for 4.50m/s^2. Find its position.

Which describes the two parts of a measurement?

2. How is temperature related to kinetic energy?

As stream velocity decrease, which factor will likely increase? A) erosion of the stream bank B) deposition of material in the stream C) amount of material carried downstream D) size of the particles carried downstream

What cells in the nervous signals travel through the nervous system

A mechanic pushes a 3.60 ✕ 103-kg car from rest to a speed of v, doing 5,130 j of work in the process. during this time, the car moves 21.0 m. neglecting friction between car and road, find v and the horizontal force exerted on the car.

Anika asks Eva to roll a basketball and then a bowling ball to her. Which requires more force to roll, and why?
