Answer:

A. When it is in a magnetic field, it becomes a temporary magnet.

Explanation:

An iron bolt is attracted to a magnet because when in a magnetic field, the iron becomes a temporary magnet.

This is because the iron aligns their electrons in the magnetic fields.

  • This causes that attraction between the magnet and the iron.
  • Metals like iron are said to be ferromagnetic
  • Unpaired electrons in iron spin in such a way that they align with the magnetic fields of the magnet.

How does temperature affect Brownian motion
Elan Coil [88]

Answer:

Explanation:

Temperature is the measure of average kinetic energy or energy in motion in a molecules. Brownian motion measure kinetic energy or how energetic the motion is and it is proportional to temperature.

Therefore, an increase in Temperature will bring about increase in kinetic energy of brownian motion. It will speed it up.

A scientist who studies teenage behavior was interested in determining if teenagers spend more time playing computer games then
natita [175]

Answer:

greater than 0.10

Explanation:

The null hypothesis is:

H_{0} = 10.2

The alternate hypotesis is:

H_{1} > 10.2

Our test statistic is:

t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}

In which X is the statistic, \mu is the mean, \sigma is the standard deviation and n is the size of the sample.

We have that:

t = 0.45

We are testing if X is greater than 0.45, so our pvalue is 1 subtracted by the pvalue of z = t = 0.45.

z = 0.45 has a pvalue of 0.6736

1 - 0.6735 = 0.3264

So our pvalue is 0.3264, which is greater than 0.10.

So the correct answer is:

greater than 0.10

A toy car has a 1.5-A current, and its resistance is 2 . How much voltage does the car require?
oee [108]

Voltage = (current) x (resistance)

Voltage = (1.5 A) x (2 ohms)

In order to MAKE 1.5 A of current flow through the toy car, you have to PROVIDE <em>3 volts</em> from the battery.
