What is the distance between lines on a diffraction grating that produces a second-order maximum for 760-nm red light at an angle of 60.0º

Answers

The condition for maximum intensity is the same as that for a double slit. However, angular separation of the maxima is generally much greater because the slit spacing is so small for a diffraction grating. For a diffraction grating with lines/mm = lines/inch, the slit separation is d = micrometers = x10^ m.

The distance between lines on a diffraction grating that produces a second-order maximum for 760-nm red light at an angle of 60.0º will be 0.0000034 m.

What is diffraction grating?

A diffraction grating is a type of optical instrument obtained with a continuous pattern. The pattern of the diffracted light by a grating depends on the structure and number of elements present.

The distance between lines on a diffraction grating that produces a second-order maximum for 760-nm red light at an angle of 60.0º is;

The equation of diffraction grating is given as;

[tex]\rm d sin \theta = n \lambda \\\\ dsin60=2 \times 760 \times 10^{-9} \\\\ d=0.00000304 \ m[/tex]

Hence,he distance between lines on a diffraction grating that produces a second-order maximum for 760-nm red light at an angle of 60.0º will be 0.0000034 m.

5One end of a wire is attached to a ceiling, and a solid brass ball is tied to the lower end. The tension in the wire is 120 N. What is the radius of the brass ball?​

Answers

Answer:

Explanation:

Force of Tension = (m)(g)

120 = (m)(9.8)

m = volume(density)

120 = (4/3)πr³(0.308)(9.8)

[tex]\frac{(120)(3)}{(pi)(0.308)(9.8)}[/tex] = r^3

solve

The radius of the brass ball is equal to 6.94 × 10⁻² m when the tension in the wire is 120 N.

What is tension?

Tension can be demonstrated as the pulling force transmitted by the means of a string, or a rope or can be described as the action-reaction pair of forces acting at each end of said elements.

The tension in the wire attached to the ceiling will be given by:

T = mg ⇒m = T/g

The radius of the brass ball is given by: [tex]r =\sqrt[3]{\frac{3V}{4\pi } }[/tex]

The density is given by: ρ = m/V = T/gV

V = T/gρ

Therefore, the expression for the radius can be written as:

[tex]r =\sqrt[3]{\frac{3T}{4\pi\rho g } }[/tex]

Given the tension in the wire, T = 120 N

The density of the brass is = 8730 Kg/m³

[tex]r =\sqrt[3]{\frac{3\times 120}{4\times 3.14 \times 8730 \times 9.81 } }[/tex]

r = 6.94 × 10⁻² m

A tortoise challenges a hare to a four-hour race. The hare is so confident of winning that he allows the tortoise to start with a 10-km lead. The hare runs at a speed of 14 km per hour, but stops for a two-hour nap in the middle of the race. The tortoise plods along at 4 km per hour the whole race. Who gets farther in four hours?

Answers

Answer: The tortoise made it.
Explanation: Because in the first place the challenge was to run a four hour race. So the focal point was to make it in 4 hrs, we see the tortoise continuously running in the race for four hours in which he covers a distance of 4km per hour which when we multiply the 4hrs with 4km distance he covered, we will discover that he covered a distance of 16km in 4hrs, so for him its mission accomplished. On the other hand the hare only covered a distance of 14km which he covered in an hour, but that wasn't the challenge, the challenge was to run for 4hours. So not only did the tortoise cover a longer distance, but he also achieved the four hour challenge.

A force of 600N is applied to an object that accelerates at a rate of 15m/s/s. What is the mass of the object?

Answers

Answer:

Because Force = mass x acceleration or F = m a, we can say Force divided by mass or F/a = m or mass so 600 divided by 15 equals 40 kg.

A projectile is fired from the ground with an initial velocity of 250 m/s at an angle 60 degrees above the horizon. Calculate the horizontal and vertical components of the velocity.

Answers

The vertical and the horizontal component of the velocity are 216.51 m/s and 125 m/s respectively.

What is velocity ?

Velocity is the rate of change of displacement.

To calculate the horizontal component of the projectile we use the formula below.

Formula:

Vx = Vcos∅........... Equation 1

Where:

Vx = Horizontal velocity of the projectileV = Velocity of the projectile∅ = Angle of the projectile

From the question,

Given:

V = 250 m/s∅ = 60°

Substitute these values into equation 1

Vx = 250(cos60°)Vx = 125 m/s

Similarly, to calculate the vertical velocity, we use the formula below

Vy = Vsin∅................. Equation 2

Where:

Vy = Vertical component of the velocity.

Also Substitute the values into equation 2

Vy = 250(sin60°)Vy = 216.51 m/s

Hence, the vertical and the horizontal component of the velocity are 216.51 m/s and 125 m/s respectively.

The cart is then pushed up the ramp, compressing the spring a distance A from equilibrium. When
released from rest, the cart oscillates up and down the ramp with a period of T₁. Assume that any friction
is negligible.
The spring is then replaced with a second spring that has a constant k2 = 2k₁, and the new period, T2, is
measured.
Determine the period of T2 in terms of T₁.

Answers

When the spring is replaced with a spring with double of initial spring constant k2 = 2k₁, the new period, T2, is [tex]\sqrt{\frac{1}{2} } \ T_1[/tex].

Period of the mass oscillation

The period of the oscillation of the mass or cart on the spring is given by the following formula;

[tex]T = 2\pi \sqrt{\frac{m}{k} } \\\\[/tex]

at a costant mass;

[tex]T_1\sqrt{k_1} = T_2\sqrt{k_2} \\\\T_2 = \frac{T_1\sqrt{k_1} }{\sqrt{k_2} }[/tex]

when spring constant is doubled, k2 = 2k1. the new period, T2 is determined as follows;

[tex]T_2 = \frac{T_1\sqrt{k_1} }{\sqrt{2k_1} } \\\\T_2 = \frac{T_1\sqrt{k_1} }{\sqrt{2} \times \sqrt{k_1} } \\\\T_2 = \frac{T_1}{\sqrt{2} }\\\\T_2 = \sqrt{\frac{1}{2} } \ T_1[/tex]

Thus, when the spring is replaced with a spring with double of initial spring constant k2 = 2k₁, the new period, T2, is [tex]\sqrt{\frac{1}{2} } \ T_1[/tex].

Will the positioning of your Slinky along the east-west, north-south, or some other orientation affect your readings? Why?

Answers

Positioning your Slinky along any direction different from its initial position will affect your reading, because there will be change in the magnetic field.

Effect of magnet on Slinky

If the Slinky is made of an iron alloy, it can be magnetized by itself. Moving the Slinky around can cause a change in the magnetic field, even if no current is flowing.

When there is a change in the magnetic field, the reading changes.

At any point, you change the orientation of the Slinky, you will need to zero the reading or adjust the Slinky back to its initial position, even if the sensor does not move.

Thus, Positioning your Slinky along any direction that is different to its initial position will affect your reading because there will be change in the magnetic field.
