I have been given this question An ultrasound wave vibrates 30 000 times a second. State the frequency of the wave help would be much appreciated Thank you in advance
Can someone give me four examples of how energy has the ability to cause motion or create change. Thanks❤
Explain,based on the motion of the gas particles,how the gas is causing the tubes to spin around as shown in the diagram above.
if the force of friction is acting on the sliding crate is 100 N how much force will be applied to maintain a constant velocity? what will the net force be acting on the crate? what will be the acceleration?
Is it possible for an object that has a constant negative acceleration to change the direction in which it is moving? Explain why or why not.
Would the friction force increase, decrease, or stay the same if Marco added two more blocks to the sled or wagon? Explain your answer.
