Explanation:
Distance divided by time gives average speed.
You would use distance an time formula to mathmaticly solve
Answer:
it will travel 69 m long consuming. it is totally wrong
Answer:
Explanation:
The electric field applies a force qE, but only in the y direction. This means that the x component of the
momentum must be conserved:
0 = Fx =dpx/dt
=⇒ px is conserved
pxi = γimvxi = pxf = γfmvxf (see the attactments)
the particle will acquire a velocity in the y
direction, and vxf <vxi. The x-component of the velocity, and thus the x-component of the momentum
must decrease.
The piece of metal will feel hotter to touch because of its heat conductance. whereas the brick does not conduct heat as well as the metal. Hence the piece of metal feeling hotter to touch.
