Ahh, ok. I just remembered that you divide the distance by speed to get time taken. So the answer would be 1.5 / 75 = 0.02 seconds.
The wavelength is the size of the wave in meters. The frequency is the number of waves that occur in a scond.
It takes the weight of that much ice to cause the plastic flow.

Yes. If the force of momentum is equal in both directions, the momentum will cancel. This can occur if two objects with equal momentum traveling in different directions collide.
The action is throwing the ball up in the air and the reaction is catching it in your hands. Further, the action caused the reaction to occur; forces acted in pairs.

One important aspect of reflex action is to help protect us without having to think. Reflex actions are involuntary and quick. They are done to meet an emergency and occur at the level of the spinal cord. Examples include the gag reflex clearing unplanned foreign objects or your eyelid closing when something gets near your eye.
A reflex action is an action that happens almost instantly without conscious thought. Grasp a very hot handle of a saucepan on the stove, and you immediately release the handle to avoid further burning by reflex action.

Involuntary actions are movements or processes that occur automatically without conscious control, such as heartbeat or digestion. Reflex actions are quick, automatic responses to a stimulus that involve a specific neural pathway, like withdrawing your hand from a hot stove.

Instead of being processed in the brain, a reflex arc is processed in the vertebra, this allows for faster reflexes. Example of when the reflex arc is used is when a person touches a hot stove. The immediate response (which the reflex arc causes) is to pull away, but it doesn't really hurt till a few seconds after. This is because the brain was first bypassed, but has now had time to process what happened.
The Achilles reflex is also known as the ankle jerk reflex. If the Achilles tendon is tapped, the foot should jerk towards its plantar surface.
The reflex arc allows sensory neurons to synapse in the spinal cord instead of the brain, allowing actions to occur relatively quickly by activating spinal motor neurons without needing to send signals through the brain. For example, a person touching a hot stove would flinch before thinking about it, and protect tissues from further damage.
Reflex action means a reaction you have given involuntarily. If you touch the immensely painful object, the touching hand or foot is removed away with out your knowledge. Here three neurons are involved. 1) Afferent 2) In the spinal cord 3) Efferent. This is called as reflex arc. Simultaneously information goes to higher centers and you notice the the problem, later on. So reflex action occurs at the level of spinal cord only.
Yes, it is possible to burp in your sleep. Burping is a reflex action that can occur when excess air in the stomach is expelled. If you swallow air before going to sleep or have certain medical conditions, you may burp while sleeping.
A somatic reflex is where the body responds to stimulus. The message from the stimulus is sent through the central nervous system via the spine, and from there it travels to the brain.
