A boeing 727-200 jet taking off from lansing airport accelerates from rest for 31.0 s before leaving the ground. its acceleration is 2.19 m/s2. assuming that the acceleration is constant, calculate the plane's speed at take off.

Imagine a gas made up entirely of negatively charged electrons. Like charges repel, so the electrons exert repulsive forces on each other.

You perform a double‑slit experiment in order to measure the wavelength of the new laser that you received for your birthday. You set your slit spacing at 1.17 mm and place your screen 8.95 m from the slits.

A pool player hit a ball with a mass of 0.25kg. The ball travels at a velocity of 15 m/s for 0.75 s until it hits the side of the pool table. What additional information is required to determine the ball's weight? A.

What is the acceleration of a spaceship that is initially at rest and then speeds up to 220 m/s in 20 seconds

Between a substance and a mixture.

Two massive objects are fixed in position. A third object is placeddirectly between the first two at the position at which the totalgravitational force on the third object due to the two massiveobjects is zero.

Which statement best describes the magnetic properties of a material? Magnetic materials have many spinning, unpaired electrons Paired electrons of magnetic materials can move to other atoms Electrons of magnetic materials are strongly held by

when we examine the structures of the other terrestrial planets in our solar system, we see that their structure is similar to Earth's. Why do you think this is the case?

An ant is crawling along a straight wire, which we shall call the x axis, from A to B to C to D
