Which is faster, light or sound? Explain.

The law of motion that states that an object's acceleration is directly related to the net force applied and inversely related to the mass of the object is

6) A 7.9 kg block is placed on an inclined plane that is 29 degrees from the horizontal. What is the acceleration of the block? Ignore friction.

Give an example of how the apparent motion of an object depends on the observer's motion.

What is the magnitude of velocity called?

To determine the amplitude of a wave, you would need to know the

In what way would a digital thermometer be preferable to those from a liquid-based thermometer? Digital thermometer readings are easier to use when performing calculations.

Why does the core of the sun contain more helium and less hydrogen than the surface of the sun?

What happens to a light ray passing through the center of a lens?

A spider crawling across a table leaps onto a magazine blocking its path. The initial velocity of the spider is 0.870 m/s at an angle of 35.0° above the table, and it lands on the magazine 0.0770s after leaving the table. Ignore air resistance.

A force of 5 N accelerates an object. The object's mass is 50 g. What is the acceleration of the object? (Formula: F=ma)
