Stars of which color have the coolest surface temperature?

ppose that you hold a vibrating 340 Hz tuning fork near a guitar string that is vibrating at 350 Hz. What you hear is?

Jesse is swinging miguel in a circle at a tangential speed of 3.50 m/s. if the radius of the circle is 0.600 m and miguel has a mass of 11.0 kg, what is the centripetal force on miguel? round to the nearest whole number.

If the distance between two objects is decreased to one fourth the original distance, what happens to the force?

10 PTS. If an electromagnetic wave has a frequency of 8 ⋅ 10^14 H z, what is its wavelength? Use λ=V/F. The speed of light is 3 ⋅ 10^8 m/s.

You lower a 2.50 kg textbook (remember when textbooks used to be made out of paper instead of being digital?) from a height of 1.85 m to 1.50 m. What is its change in potential energy?

If a magnetic field is to exert a force on a current-carrying wire, the field must have some vector component:

What advantages does locomotion give to an animal

In a physics lab, a 0.500-kg cart (Cart A) moving with a speed of 129 cm/s encounters a magnetic collision with a 1.50-kg cart (Cart B) that is initially at rest. The 0.500-kg cart rebounds with a speed of 45 cm/s in the opposite direction.
