What is the wavelength in nm of a light whose first order brightband forms a diffraction angle of 19.0°, and the diffraction grating has 600.0 lines per mm? round to the nearest whole number. nm

Answers

The wavelength of light will be 195.34 nm.

What is wavelength?

The distance between two successive troughs or crests is known as the wavelength. The peak of the wave is the highest point, while the trough is the lowest.

The wavelength is also defined as the distance between two locations in a wave that have the same oscillation phase.

The wavelength from the diffraction grating formula is found as;

[tex]\rm m \lambda= d sin\theta \\\\ \lambda= \frac{dsin \theta }{m}\\\\ \lambda= \frac{600 \times sin 19^0 }{1} \\\\ \lambda= 195.34\ nm[/tex]

Hence the wavelength of light will be 195.34 nm.

A solid cylinder with diameter 20cm has an angular velocity of 10m/s and angular momentum of 2kgm^2/s. What is its mass?

Answers

Hi there!

Recall the equation for angular momentum:
[tex]L = I\omega[/tex]

L = Angular momentum (kgm²/s)
I = Moment of Inertia (kgm²)
ω = angular velocity (rad/s)

We know that the Moment of Inertia of a solid cylinder is equivalent to:
[tex]I = \frac{1}{2}MR^2[/tex]

M = mass (kg)
R = radius (m)

Plug in the givens to solve for the moment of inertia. Remember to divide the diameter by 2 for the radius, and to convert to meters.

[tex]r = \frac{d}{2} = 20/2 = 10 cm \\\\10 cm = 0.1 m[/tex]

[tex]I = \frac{1}{2}M(0.1^2) = 0.005 M[/tex]

We can rearrange the equation of angular momentum to solve for mass.

[tex]L = 0.005M * \omega\\\\\frac{L}{0.005 \omega} = M \\\\M = \frac{2}{0.005(10)} = \boxed{ 40 kg}[/tex]

Complete Question

Air in a piston-cylinder assembly undergoes a process from state 1, where T1 = 300K, P1 = 100 kPa, to state 2, where T2 = 500K, P2 = 650 kPa. Using the ideal gas model for air, determine the change in entropy between the two states, in kJ/kg-K

The change in entropy between the two states, in a piston cylinder assembly, undergoes a process from state 1 where t1=300k is 2.36 kJ/kg K.

How to find change in entropy?

The change in entropy can be find out using the following formula,

[tex]S1-S2=s^oT_1-R\ln \dfrac{p_2}{p_1}[/tex]

Here, (p1 and p2) are the pressure at state 1 and 2 and R is the gas constant. The value of R is,

R=(8.314/28.97).

Air in a piston-cylinder assembly undergoes a process from state 1, where T1 = 300 K, p1 = 100 kPa, to state 2. where T2 = 500 K, p2 = 650 kPa.

Put these values,

[tex]S_2-S_1=1.70203_1-\dfrac{8.314}{28.97}\ln \dfrac{10\text { bar}}{1\text { bar}}\\S_2-S_1=2.36\rm\; kJ/kg K[/tex]

Thus, the change in entropy between the two states, in a piston cylinder assembly undergoes a process from state 1 where t1=300k is 2.36 kJ/kg K.

What does the area of an acceleration time graph represent?

Answers

The area under the acceleration time graph represents change in velocity


The graph is plotted with acceleration on the vertical axis and time on the horizontal axis. The area under such graph represents change in velocity

The area of an acceleration- time graph represents the change in velocity. The pace at which a body's velocity varies is represented by acceleration, which is a vector quantity.

What is acceleration?

The rate of change of velocity with respect to time is known as acceleration. According to Newton's second law, the eventual effect of all forces applied to a body is its acceleration.

The formula for acceleration is;

What are the seasonal changes in the weasel in florida and the weasel in wyoming

Answers

Answer:

The differences between the Florida's weasel and in Wyoming's is that I can see that in Wyoming it has a lot of snow so Wyoming's weasel fur is more thicker than Florida's weasel.

Explanation:

Overmore, in Florida's weasel the weasel's fur is much more less then Wyoming's weasel's fur. Subsequently, their fur color is very different. In Wyoming's weasel fur, it's white fur help them blend in the snow. In Florida's weasel fur, it's brown and help blend in the grass(soil).

Weasels are small animals with long tail. Their diet will change in each seasons and will causes consecutive changes in body weight also.

What is seasonal change?

The changes occurs in a living body or in a material with respect to different seasons is called seasonal changes.Weasels have coats that change from light brown to white in the winter. They are also known as ermines or short-tailed weasels.

In both the spring and the fall, the hue of their bodies changes, starting at their belly and moving outward. Long-tailed weasels and other species may also turn at least partially white.

The hue shift is caused by daylight duration rather than temperature. Weasels may therefore appear dazzling white in the winter against a brown environment before snow begins to fall. This makes them easy prey for larger predators like foxes, martens, and badgers during milder winters.

These little creatures eat a lot. Winter weasels forage often and consume roughly 40% of their body weight each day. Winter weasels have coats that change from light brown to white in the winter.

These pests, which can weigh as little as two ounces, are vicious and may attack prey that is larger than themselves. Weasels have excellent senses and are highly nimble. Because of this, they are difficult to catch and remove, both for humans and for predators.

Weasels are a sign of a healthy population of rodents or other prey on a property in the winter. The pests frequently reserve a portion of their meals for later.

A wave pulse on a spring is 5.40 cm high and oriented upward. This pulse meets another pulse of the same shape which is 1.10 cm high but oriented downward.
At the moment when the two pulses come together, what is the amplitude of the resulting pulse? Note: if the pulse is oriented upward, make its amplitude positive. If it is oriented downward, make its amplitude negative.

Answers

The resulting positive amplitude of the two waves after the superimposition is 4.30 cm.

Amplitude of the waves

The amplitude of the waves is the maximum displacement of the wave. This is the vertical position of the wave measured from the zero origin.

After the superimposition of the two similar waves, the resulting amplitude will be less than the initial amplitude of the wave with the highest vertical height since the superimposition creates destructive interference.

Resulting amplitude of the two waves is calculated as;

A = 5.4 cm - 1.10 cm

A = 4.30 cm

Thus, the resulting positive amplitude of the two waves after the superimposition is 4.30 cm.

Then, Momentum before = Momentum after;

Momentum before = m1v1 + m2v2 = 4000(.83) + 8000(0)

Momentum after: (m1 + m2)v3 → (4000 + 8000)v3
