Is it possible for speed to be constant while acceleration is not zero?

Sure enough !

Acceleration means any change in speed OR DIRECTION of motion.

So if something is moving in a circle or around a curve, even at constant
speed, its direction is changing, so acceleration is not zero.

Answer:

A) Energy is dissipated into heat and sound energy due to Friction

B) The energy goes into heat and sound energy due to friction again, otherwise the cart would accelerate due to an unbalanced force. Therefore, we know there's friction, and the friction causes energy loss.

A 900 kg car travelling at 12 m/s due east collides with a 600 kg car travelling at 24 m/s due north. As a result of the collisi
katrin [286]

Calculate force of each car:

P1 = 900 kg x 12m/s = 10,800

P2= 600 x 24 = 14,400

Degree of travel = arctan(14,300/10800)

Degree of travel = 53.1 N of E

An Aeolian harp (named after Aeolus, the Greek god of the wind) consists of several strings fixed to a frame or a sounding box.
Mashcka [7]

Answer:

0.434 m

Explanation:

We are given that

Mass per unit length=\mu=\frac{m}{l}=2.4 g/m=2.4\times 10^{-3} kg/m

1 kg=1000 g

Tension=350 N

Fundamental frequency=f=440 Hz

We have to find the length you should make it.

We know that

l=\frac{1}{2f}\sqrt{\frac{T}{\mu}}

Using the formula

l=\frac{1}{2\times 440}\times\sqrt{\frac{350}{2.4\times 10^{-3}}}

l=0.434 m

Hence, you should make it 0.434 m long.
