If you're going 80 mph how long does it take to 80 miles

Increasing the two objects will cause the gravitational force between the objects to decrease.

Bears and coyotes both consume large plant-eating mammals such as deer. When the deer are in short supply, bears and coyotes may fight over the prey. This type of biological interaction is called

A particle's velocity is described by the function vx=kt2m/s, where vx is in m/s, t is in s, and k is a constant. The particle's position at t0=0s is x0 = - 8.10 m. At t1 = 2.00 s, the particle is at x1 = 8.00 m.

The contribution of Tycho Brahe was primarily his calculations observation inventions theories

Which of these is most likely a characteristic of a parent isotope before it releases radioactive particles? Select one: a. stable nucleus b. stable electrons c. unstable electrons d. unstable nucleus

A 0.12 kg paper airplane flies in a straight line at a speed of 1.3 m/s. How much kinetic energy does the airplane have?

Each atom is composed of electrons and positive material. The mass of the atom is evenly spread throughout the atom. Neutrons are located in the center of the atom. Positive charge occupies a very small volume in the atom.

A hot-air balloon is ascending at the rate of 14 m/s and is 84 m above the ground when a package is dropped over the side. (a) How long does the package take to reach the ground? (b) With what speed does it hit the ground?

Now assume that the pitcher in Part D throws a 0.145-kgkg baseball parallel to the ground with a speed of 32 m/sm/s in the + x direction. The batter then hits the ball so it goes directly back to the pitcher along the same straight line.

How far away is a cliff if an echo is heard 0.486 s after the original sound? Assume that sound traveled at 343 m/s on that day.
