Earth exerts a 1.0 N gravitational force on an apple. Does the apple accelerate toward Earth, or does Earth accelerate toward the apple? Explain your answer.

What is the acceleration lane?

Which is most likely responsible for the formation of cancer cells? A. An antibiotic B. A Mutagen C. A Bacterium D. A Parasite

Nearly all liquids and solids are nearly opaque to radiation at nearly all wavelengths. why is that

What is the magnitude and direction of an electric field that exerts a 2.00*10-5N upward force on a - 1.75μC charge?

A car is moving with a velocity (3.0 m/s) € x ˆ + (1.0 m/s) € y ˆ and 3.0 seconds later its velocity is (6.0 m/s) € x ˆ - (3.0 m/s) € y ˆ. What is the direction of the average acceleration of the car?

When water vapor condenses on the inside of a window, the window becomes

Try this out. Use a calculator! We can use the formula KE=0.5m*V^2. To find the kinetic energy (KE) of a payload of mass (m) 100 kg as it flies through the air at the velocity (v) of 55 m/s. (Multiply 0.5 x the mass x velocity squared.
