A glass marble is rubbed against a piece of silk. As a result the piece of fabric acquires extra electrons. What happens to the
Natalija [7]

Answer:

There was an electron transfer where the marble has lost the same amount of electrons (being positively charged) that the piece of silk has gained (being negatively charged).

Explanation:

As a result of this transfer of electrons and the charges induced in the objects they will attract.

When a body is endowed with electrical properties, that is, it acquires electrical charges, it is said to have been electrified.

Electrification is one of the phenomena that studies electrostatics.

To explain how static electricity originates, we must consider that matter is made of atoms, and atoms of charged particles, a nucleus surrounded by a cloud of electrons. Normally, matter is neutral (not electrified), it has the same number of positive and negative charges.

Some atoms are easier to lose their electrons than others. If a material tends to lose some of its electrons when it comes into contact with another, it is said to be more positive in the Triboelectric series. If a material tends to capture electrons when it comes into contact with another material, that material is more negative in the triboelectric series.

5. A sample of gas occupies 1.55 L at 27 degrees Celsius and 1.00 atm pressure. What will the volume be if the pressure is incre
Sergio039 [100]

Answer:

The volume will be 0.031 L

Explanation:

Since temperature is constant, Boyle's law is applied in this case.

Boyle's law States that at constant temperature, the volume of a given mass of a gas is inversely proportional to it's pressure.

From this statement it was deduced that P1V1 = P2V2

From the question, P1 = 1atm, V1 = 1.55L, P2 = 50 atm and V2 is to be calculated.

V2 = P1V1/P2

= 1×1.55÷50

=0.031 L

A home remodeling company charges $10 per square yard for installing new carpets. What is the cost for installing a carpet for a
balu736 [363]

Answer:

$200.0 is the cost for installing a carpet for a room that measures 12.0 feet by 15.0 feet.

Explanation:

Length of the room = l = 15.0 ft = \frac{15.0}{3} yard=5.0 yard

Width of the room = w = 12.0 ft = \frac{12.0}{3} yard=4.0 yard

(1 yard = 3 feet)

Area of the room = l × w = 4.0 yard\times 5.0 yard = 20.0 yard^2

Cost for installing a carpet for a room = $10 per square yard

Cost for installing a carpet for a room wit area 20.0 square yard :

20.0 yard^2\times $10/ yard^2=$200.0

$200.0 is the cost for installing a carpet for a room that measures 12.0 feet by 15.0 feet.
