Explain whether a car can move with changing velocity while maintaining constant speed?
Velocity is a quantity that has magnitude and direction. The magnitude of velocity is what we call "speed".If the velocity is constant, then its magnitude and direction are both constant.Constant magnitude means constant speed.So the answer to the question is "Yes".
Explain why parachutist and snowflakes donot fall with a constantly accelerating motion?
Parachutists and snowflakes do not fall with constantly accelerating motion because of air resistance. As they fall through the air, they experience a drag force that counteracts the force of gravity, eventually reaching a terminal velocity where the forces are balanced and they fall at a constant speed. This prevents them from accelerating indefinitely.
How would you explain a bottle moving across the water in the same direction that the waves are traveling?
The bottle is likely being carried by the current or the movement of the water caused by the waves. The direction of the waves propels the bottle forward, moving it in the same direction as the waves.
Explain the motion of the air particles that carry a sound wave include the direction that the sound is traveling in your explanation?
In a sound wave, air particles vibrate back and forth in the same direction that the sound wave is traveling. This means that when a sound is produced, it creates a series of compressions and rarefactions in the air as the energy carried by the particles moves through the medium in a longitudinal direction.
When is velocity parallel to acceleration?
Velocity is parallel to acceleration when an object is moving with constant speed in a straight line, as the direction of the velocity and acceleration vectors are aligned. This means that the object's speed may be constant, but its direction can change.
An ice skater glides around a rink at a constant speed of 2 ms is the skater acceleratng explain your answer?
Acceleration is change in velocity. These are vectors that have magnitude and direction. Changing either magnitude (speed) or direction will have the skater be accelerating. SO, if the skater is going at a constant speed of 2m/s in a straight line, he is not accelerating. If he is at a constant speed of 2m/s traveling in a circle (you gave the word "around"), he is accelerating. Going around in circles means there is a force constantly changing your direction. Obviously that force is coming from the skaters legs.

What is an accelerating universe?
An accelerating universe is a theory which describes and seeks to explain the increasing rate of the expansion of the universe.

Can an object have a constant speed and the varying velocity at the same time explain?
Velocity is a vector. A vector has a magnitude and a direction. The scalar or magnitude portion of velocity is speed. Velocity is a constant only when both the speed and direction are not varying. Hence, when the speed is changing, the velocity cannot be a constant.

If you are applying the brakes on your bicycle are you accelerating explain?
Using brakes slows your speed.
Can your body sense constant velocity and explain?
Your body cannot sense constant velocity. For example, you cannot sense that the earth is turning nor can you sense that the earth is orbiting around the sun. And, if you are in a vehicle that is traveling with a constant velocity, you cannot sense that you are moving unless your eyes sense a change in position.
Can an object be accelerated if it is moving with constant speed if yes explain giving examples?
Yes, an object can be accelerated even if it is moving at a constant speed if the direction of its velocity changes. This change in velocity, even if the magnitude of speed remains constant, indicates acceleration. For example, if a car is moving around a circular track at a constant speed, its direction is changing constantly, resulting in acceleration.
