Insect A moves 5.0 m/min and insect B moves
mezya [45]

Answer:

insect B by 12m

Explanation:

30min = 1800s (times by 60)

5m/min x 30min = 150m

9cm/s x 1800s = 16,200cm = 162m

162m - 150m = 12m

Two round concentric metal wires lie on a tabletop, one inside the other. The inner wire has a diameter of 18.0 cm and carries a
Helen [10]

Answer:

Explanation:

The wires are in circular shape . They have common center .

magnetic field due to circular wire is given by the formula

B = \frac{\mu_0\times I }{2r}

 where I is current , r is radius of the coil .

magnetic field due to inner wire

= \frac{\mu_0\times 10 }{2\times.09}

magnetic field due to outer wire

= \frac{\mu_0\times I }{2\times.15}

These should be equal  and opposite so that by cancelling each other , they create zero field.

\frac{\mu_0\times 10 }{2\times.09}  = \frac{\mu_0\times I }{2\times.15}

I = 16.66  A

Direction of current should be in opposite direction ie anticlockwise when looking from above.

Which electrode in Thomson’s vacuum tube was positively charged
Taya2010 [7]

Anode

Explanation:

The anode in the gas discharge tube used by Thomson in his experiment was the positively charged electrode.

Using the gas discharge tube, Thomson made the remarkable discovery of cathode rays.

The rays moves from the negatively charged cathode to the positively charged anode. This indicated that the rays carry positive charges.

Some parts of the tube are:

  • Cathode - negatively charged electrode
  • Power source
  • Gas at low pressure
  • Outlet to vacuum pump
