The formula applicable:

Period, T = 1/f --- Where T = period (s), and f = frequency (Hz).

Substituting by use of the values of frequency given in the current scenario,

T = 1/440 = 2.27*10^-3 seconds

Question
Which of the following will induce a reduced emf in the secondary coil of a generator? fewer number of loops in the secondary coil. greater number of loops in the primary coil. larger area in the secondary coil. constant potential in the primary coil.
Solution 1

Answer:

fewer number of loops in the secondary coil.

Explanation:

The transformer equation states that:

\frac{V_p}{N_p}=\frac{V_s}{N_s}

where

Vp is the voltage in the primary coil

Np is the number of loops in the primary coil

Vs is the emf induced in the secondary coil

Ns is the number of loops in the secondary coil

Solving the expression for Vs,

V_s = \frac{N_s}{N_p}V_p

Therefore, we see that in order to reduce the emf in the secondary coil, we can reduce Ns, the number of loops in the secondary coil. So the correct option is

fewer number of loops in the secondary coil.

Question
Andre heated several solid crystals of a substance called iodine, and the iodine changed directly to a gas. The iodine gas then cooled and changed into droplets. Which two processes did the iodine undergo? A. condensation, then vaporization B. sublimation, then condensation C. deposition, then sublimation D. vaporization, then deposition
Solution 1

The correct choice is

B. sublimation, then condensation

Sublimation is the name of the process where a solid directly converts into gas on heating. on heating solid crystals of iodine directly change into gas. hence this is sublimation.

condensation is the process where gas is converted into liquid on cooling.

here iodine gas is being converted into droplets on reducing the temperature. hence this is condensation.


Solution 2
The answer in B)sublimation, then condensation.

Question
a 10.0 kg ball falling at 10.0 m/s hits a mattress and comes to a complete stop in 1 s. what force does the mattress exert to stop the ball
Solution 1
Using Newton's second law;

F = ma, where m = mass, a = acceleration or deceleration

a = Δv/t = (v-u)/t, but v= 0, u = 10 m/s, t = 1.
Then,
a = (0-10)1 = -10 m/s^2

Substituting;
F = ma = 10*-10 = -100 N

The  mattress exerts 100 N to stop the ball.
Question
If the building absorbed so much heat that it turned into a liquid, then it would have undergone a phase change known as _____. freezing vaporizing condensing melting
Solution 1

Answer:

Melting

Explanation:

If the building absorbed so much heat that it turned into a liquid, then it would have undergone a phase change known as:

  • freezing. NO. Freezing is the process in which a liquid turns into a solid.
  • vaporizing. NO. Vaporizing is the process in which a liquid turns into a gas.
  • condensing. NO. Condensing is the process in which a gas turns into a liquid.
  • melting. YES. Melting is the process in which a solid turns into a liquid.
Solution 2
When something gets to hot it reaches its melting point, meaning it melts. the the answer would be D melting
