6. Current in length of copper wire. Two students hold a 7.6 m length of copper wire horizontally, in an east-west direction, in the school yard. The wire is
moved vertically downwards at a speed of 0.30 ms?
Given that, in this yard, the horizontal component of the Earth's magnetic field is 4.0 x 10-5 T, and perpendicular to the
wire, calculate the emf detected, to two significant figures, by a very sensitive meter placed across the ends of the wire.

Explain how the energy of rubber ball is tranforned as it roll down a ramp. give evidence that the energy of the og the ball remains the same at all points on the ramp

What property of an object determines its inertia?

One hazard of space travel is debris left by previous missions. there are several thousand masses large enough to detect by radar orbiting the earth, but there are far greater numbers of very small masses such as flakes of paint. calculate the force exerted by a 0.110 mg chip of paint that strikes a space shuttle window at a relative speed of 5.00 ✕ 103 m/s and sticks, given the collision lasts 6.00 ✕ 10-8 s. such a collision chipped the window of the ill-fated challenger in june 1983, causing $50,000 of damage.
