miv72 [106K]

Answer:

The time is 2.8 ms.

Explanation:

Given that,

Capacitor = 0.12 μF

Resistance = 10 kohm

Voltage = 12 V

Charge Q = 0.9 Q₀

We need to calculate the time constant

Using formula of time constant

T=RC

Put the value into the formula

T=10\times10^{3}\times0.12\times10^{-6}

T=0.0012\ sec

We need to calculate the time

Using formula of time

Q=Q_{0}(1-e^{\frac{-t}{T}})

Put the value into the formula

0.9Q_{0}=Q_{0}(1-e^{\frac{-t}{0.0012}})

ln (0.1)=\dfrac{-t}{0.0012}

t=0.00276\ sec

t=2.8\ ms

Hence, The time is 2.8 ms.

How does incident light that falls on an object affect the motion of electrons in the atoms of the object?
KonstantinChe [14]

Explanation:

Incident light makes an electron oscillate. The electrons emit light or absorb the light, collide with other electrons, thereby converting light energy to more internal energy. and convert it to heat.

Light wave of a given frequency is incident on a material with electrons having the same vibrational frequencies, then electrons absorb the energy of the light wave and transform it into vibrational motion.

The volume of a gas is reduced from 4 l to 0.5 l while the temperature is held constant. How does the gas pressure change?
shusha [124]

Answer:

The pressure increases by a factor 8

Explanation:

For a gas held at constant temperature, Boyle's law can be applied. It states that the product of the gas pressure and the gas volume is constant, so we can write:

p_1 V_1 = p_2 V_2

where

p_1 is the initial pressure

p_2 is the final pressure

V_1 is the initial volume

V_2 is the final volume

For the gas in this problem, the volume is reduced from

V_1 = 4 L

to

V_2 = 0.5 L

so we can rewrite the equation as

\frac{p_2}{p_1}=\frac{V_1}{V_2}=\frac{4 L}{0.5 L}=8

this means that the pressure of the gas will increase by a factor 8.
