A 3.8 kg object to is lifted 12 meters. approximately how much work is performed during lifing? A) 45.6 J B) 588 J C) 466.9J D) 372.4 J

Sixty miles is how many sec?

A plucked guitar string produces a sound wave with a wavelength of 0.15 m and a velocity of 10.5 m/s, what is the frequency of the wave?

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.

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

Can you chemical change or alter DNA

Give an example in which velocity is zero yet acceleration is not.
