A rock hits the ground with a speed of 7 m/s and a kinetic energy of 100 J. What is the rock's mass?

While exploring a section of land far from the sea, an explorer discovers a dome-shaped geologic structure with gently sloping sides. Which of the following has the explorer most likely discovered?

Calculate the inductance of a solenoid that is 1.7 cm long and 3.3 mm in diameter, with 195 turns of wire.

If R1 = 6 Ω, R2 = 8 Ω, R3 = 2 Ω, ε1 = 4 V, and ε2 = 14 V, what is the current in R

What is the electric power used by an appliance if the current is 2 A and the voltage is 50 volts? Show work and include all units

In class you learned that physics needs only seven (7) basic quantities to measure everything in the known universe. However, it is combinations of these quantities that we use mostly, especially in our everyday lives.

What is one way to increase the amplitude of a wave in a medium

A net force of 3000 N is accelerating a 1200 kg elevator upward. If the elevator starts from rest, how long will it take to travel up 15 m?

The frequency of a given region of the electromagnetic spectrum ranges from 3 _ 1016 _ 3 _ 1019 hertz. Which type of wave is found in this region?

A student is testing the kinematic equations for uniformly accelerated motion by measuring the time it takes for light-weight plastic balls to fall to the floor from a height of 3 m in the lab. The student predicts the time to fall using g as 9.

Newton's Second law of Motion (F = ma) is one of the basis of forces and motion. How is it very similar to his First law and why is finding the acceleration of the system (the main reason we use it) so important to solving physics and real world
