As the velocity of the sound source approaches the speed of sound, the wave fronts ahead of the object begin to appear as a single wave front and when the velocity of the sound source exceeds the speed of sound, the wave fronts form a cone shaped shockwave.

According to newton’s first law of motion, which force is expected to cause a body to accelerate?

Two masses are connected by a rope that hangs over a pulley as shown below. the pulley is a uniform cylinder of radius 푅=0.381meters and mass 푀=3.1푘푔. initially 푚"is on the ground and 푚#rests 2.5 meters above the ground. if the system is released, use conservation of energy to determine the speed of 푚#just before it strikes the ground. assume the pulley bearing is frictionless.

It takes a lot of energy to get the temperature of water to increase and eventually boil because water has a high heat.
