If the amplitude of a wave is increased the frequency of the wave will

A car travels at a constant velocity of 70 mph for one hour. At the second hour, the car's velocity was 60 mph. At the third hour, the car's velocity was 80 mph.

What is the most work that can be done with 100 joules if energy

When you measure the current and voltage in a ac circuit with a multimeter, is your result the peak value or the rms value?

How fast would the moon need to travel in order to escape the gravitational pull of Earth, if Earth has a mass of 5.98 X 1024 kg and the distance from Earth to the moon is 3.84 x 108 m?

Water vapor sometimes condenses to form water droplets called dew. When this occurs, what type of change is it? A. physical only B. chemical only C. physical and chemical

The intrapleural pressure is - 4 mmHg relative to atmospheric and the transpulmonary pressure is 5 mmHg relative to atmospheric.

A hot-air balloon is 150 feet above the ground when a motorcycle passes directly beneath it (traveling in a straight line on a horizontal road). The motorcycle is traveling at 40 mph.

How do I calculate initial speed by using the slope of a graph? The graph shows the relationship between S { (sin2ϴ) / g} and the average range of a projectile in meters.

You push a 50 kg wooden box across a wooden floor at a constant speed of 1.0 m/s. The coefficient of kinetic friction is 0.15. Now you double the force on the box. How long would it take for the velocity of the crate to double to 2.0 m/s?

A star is in hydrostatic equilibrium when the outward push of pressure due to core burning is exactly in balance with the inward pull of gravity.
