Answer: b. infrared

Explanation:

The visible light with the smaller frequency is associated with the color red.

While the blue is the one with the larger frequency.

Now, as the name says, infrared waves are the ones with a frequency just below the one of the red visible light.

Where the frequency of the red light is something around (4.3*10^14 Hz)

and the frequency of the infrared waves is in the range between (10^12 Hz and 10^14 Hz)

Then the correct option is b, infrared.

how much energy is transferred when 1 gm of boiling water at 100 degree celcius condenses to water at 100 degree celcius?

Mademuasel [1]

The latent heat of vaporization for water is 2257 KJ per Kg . I'm pretty sure that's exactly the same as 2257 joules per gram. So ... When 1 gm of STEAM at 100 C condenses to 1 gm of liquid water at 100 C, it releases 2257 joules of heat energy to its environment.

The pressure of a 1.0 liter balloon is at 1 atm at 293 K if you were to take the balloon into a freezer that is still at One ATM

Fofino [41]

Here we can say that number of moles as well as pressure will remain same for the balloon

so here we can say by ideal gas equation

$PV = nRT$

so here for constant pressure and constant number of moles we have

$\frac{V_1}{T_1} = \frac{V_2}{T_2}$

$\frac{1}{293} = \frac{V}{263}$

now by rearranging the equation we have

$V = \frac{263}{293}$

$V = 0.89 Liter$

so final volume will be 0.89 liter

What is your average velocity after going 15 meters east followed by 20 meters

adelina 88 [10]

Answer:

0.5 m/s

Explanation:

Velocity = displacement/time taken

going 15 meters east and then 20 meters west gives a displacement of 5 meters.

Velocity v = 5/10

= 0.5 m/s

Calculate the momentum of of a 1,5000 kg car traveling at 6 m/s

ANEK [815]

Answer: 90000 kgm/s

Explanation:

Given that,

Momentum of car = ?

Mass of car = 1,5000 kg

Velocity of car = 6 m/s

Recall that momentum is the product of mass of the moving object by its velocity

i.e Momentum = mass x velocity

Momentum = 15000kg x 6m/s

= 90000kgm/s

Thus, the momentum of the car is 90000 kgm/s

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:

$p_1 V_1 = p_2 V_2$
