The temperature of a system rises by 45 °C during a heating process. Express this rise in temperature in Kelvin and Fahrenheit.

Two rather unequal cars are competing in a drag race. For simplicity, let's assume that the accelerations of the cars are constant. Car 1 has an acceleration of 3.3 m/s2, while Car 2 has an acceleration of 5.9 m/s2. Car 2 gets off to a late start, 0.

Tech A says that as engines gain miles, the spark plug gap increases, which raises the ignition system's available voltage. Tech B says that misfire occurs when required voltage is higher than available voltage.

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?

Why does a buoyant force act on every object in a fluid? Pressure pushing up on the bottom of the object is greater than the pressure pushing down on the top.
