Which type of radiation has a negative charge? alpha beta gamma which type of natural radiation is pure energy? beta alpha gamma which type of natural radiation has the most massive particles? gamma alpha beta?

What factors increase a wave's amplitude?

Infrared observations of the orbits of stars close to the galactic center indicate a small object at the center with a mass of about how many solar masses?

A box of mass 15.1 kg with an initial velocity of 2.33 m/s slides down a plane, inclined at 23◦ with respect to the horizontal. The coefficient of kinetic friction is 0.56. The box stops after sliding a distance x.

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.

How are mass and weight different? a. Mass is the space an object takes up and weight is the effect of gravity on mass. b. Mass is the amount of matter and weight is the effect of gravity on mass. c.
