You have a horizontal cathode ray tube (CRT) for which the controls have been adjusted such that the electron beam should make a

single spot of light exactly in the center of the screen. You observe however that the spot is deflected to the right. It is possible that the CRT is broken. But as a clever scientist you realize that your laboratory might be in teh middle of a electric or magnetic field. Assuming that you do not have a compass, anymagnets, or any charged rods, how do you use the CRT itself to determine if the CRT is broken, in an electric field, or in a magnetic field?You cannot remove the CRT from the room>

Answer:

Explanation:

Rotate it slowly to establish whether the spot moves. If it is broken, it will stay as it is. By rotating it the electrons' path to the centre of the screen will be tilted to another position by any external disturbing field.

If the back of the truck is 1.3 m above the ground and the ramp is inclined at 22 ∘ , how much time do the workers have to get t
solong [7]
Refer to the diagram shown below.

Assume that
(a) The piano rolls down on frictionless wheels,
(b) Wind resistance is negligible.

The distance along the ramp is
d = (1.3 m)/sin(22°) = 3.4703 m

The component of the piano's weight along the ramp is
mg sin(22°)
If the acceleration down the ramp is a, then
ma = mg sin(22°)
a = g sin(22°) = (9.8 m/s²) sin(22°) = 3.671 m/s²

The time, t, to travel down the ramp from rest is given by
(3.4703 m) = 0.5*(3.671 m/s²)*(t s)²
t² = 3.4703/1.8355 = 1.8907
t = 1.375 s

Answer: 1.375 s
