The final momentum of the skater is 3.77 m/s.

Momentum is the product of mass and acceleration. Recall that the principle of conservation of linear momentum states that total momentum before collision must equal the total momentum after collision.

Thus;

(50 Kg × 0 m/s) + (55Kg ×  7.2m/s) = (50 Kg + 55Kg) v

v =  (55Kg ×  7.2m/s)/(50 Kg + 55Kg)

The average speed of the ball is 0.25 m/s

Define speed.

Velocity is the pace and direction of an object's movement, whereas speed is the time rate at which an object is travelling along a path.

The displacement of a body over a predetermined amount of time is referred to as velocity. It has a scalar value. A vector quantity, that is.

Distance/Time = Speed.

A force has the power to alter an object's motion's direction. A greater force acting on an object will result in a greater change in motion. To undergo the same change in motion, a heavier object needs more force than a lighter thing.

S = Average speed

d = total distance

t = total time.

S = d/t.

Option 2

The incident angle θ1 of the light in the diamond is approximately 7.91 degrees.  

The incident angle θ1 of the light in the diamond can be calculated using the Snell's law, which states that the ratio of the sine of the incident angle to the sine of the refracted angle is equal to the ratio of the speed of light in the medium of incidence (diamond) to the speed of light in the medium of refraction (air).

Using the values given in the question:

The angle of incidence θ1 = 50 degrees

The refractive index of diamond (n1) = 2.419

The refractive index of air (n2) = 1.000

The speed of light in a vacuum (c) = 299,792,458 meters per second

We can calculate the incident angle θ1 using the Snell's law:

sin(θ1) / sin(θ) = (c/n1) / (c/n2)

sin(θ1) = (c/n1) / (c/n2) * sin(θ)

θ1 = (c/n1) / (c/n2) * sin(theta)

Since the sine of an angle is always between -1 and 1, we can solve for θ1:

0.5 = (299,792,458 / 2.419) / (299,792,458 / 1.000) * sin(theta)

sin(θ1) = 0.5 / (299,792,458 / 1.000) * sin(θ)

sinθ1) = 0.5 / (2.998 x \(10^6\)) * sin(θ)

sin(θ1) = 0.5 / 7.91 x \(10^-5\) * sin(theta)

θ1= 7.91 x \(10^-5\) * sin(theta)

Therefore, the incident angle θ1 of the light in the diamond is approximately 7.91 degrees.

Answer:

Part A: 2.24

Part B: 551 nm

Explanation:

\(n_1*v_1=n_2*v_2\) (n1 and n2 are the indexes of refraction, and v1 and v2 are the velocities of light)

Rearrange to isolate n2: \(\frac{n_1*v_1}{v_2} =n_2\)

Speed of light in a vacuum is 3*10^8 m/s, and a vacuum has index of refraction of 1.

\(n_2=\frac{1*3*10^8}{1.34*10^8}\) = 2.24

Air has index of refraction of about 1, so speed of light in air is about 3*10^8 m/s.

Speed of light is its frequency times its wavelength. Travelling through different mediums does not affect the frequency of the light.

v = λ*f (c is speed of light in diamond, λ is wavelength of light, and f is frequency of light)

Rearrange to isolate f: f = v/λ

246 nm = 2.46*10^-7 m

f = \(\frac{1.34*10^8}{2.46*10^{-7}}\) = 5.45*10^14 Hz

To find wavelength of light in air, rearrange v = λ*f to λ = v/f = \(\frac{3*10^8}{5.45*10^{14}}\) = 5.51*10^-7 m = 551 nm

Part a. The index of refraction of diamond at this wavelength is 0.0434.

Part b. The wavelength of the light in air is approximately 1.06× \(10^8\) m/s.  

The index of refraction of diamond at this wavelength, we need to use the formula:

n = c/v

here n is the index of refraction, c is the speed of light in a vacuum, and v is the speed of light in the medium. We know that the speed of light in a vacuum is 299,792,458 m/s, so we can substitute this value into the formula:

n = (1.34× \(10^8\) m/s)/(299,792,458 m/s)

n = 0.0434

The index of refraction of diamond at this wavelength is 0.0434.

The wavelength of the light in air, we can use the formula:

wavelength = c/n

here wavelength is the wavelength of the light in air, and n is the index of refraction of air. We know that the index of refraction of air is 1, so we can substitute this value into the formula:

wavelength = (1.34× \(10^8\) m/s)/(1)

wavelength = 1.34× \(10^8\) m/s

Therefore, the wavelength of the light in air is approximately 1.06× \(10^8\) m/s.

Fuel consumption rate refers to the amount of fuel consumed by a vehicle or equipment over a certain period of time. Approximately 3570.82 kiloliters of fuel are saved in a typical 2000 km trip.

Fuel consumption rate is typically measured in units such as gallons per hour (gal/hr) or liters per hour (L/hr). The fuel consumption rate indicates the efficiency or effectiveness of fuel utilization by the vehicle or equipment.

The fuel consumption rate represents the rate at which fuel is consumed by the Airbus A320 Neo aircraft. It is specified as 2200 gallons per hour (gal/hr) before the speed reduction and 2000 gallons per hour (gal/hr) after the speed reduction. This means that the aircraft consumes fuel at a rate of 2200 gallons per hour (gal/hr) when flying at a speed of 525 miles per hour (mph) and at a rate of 2000 gallons per hour (gal/hr) when flying at a reduced speed of 475 miles per hour (mph).

To calculate the amount of fuel saved in a typical 2000 km trip, we need to convert the fuel consumption rate from gallons per hour (gal/hr) to kiloliters per kilometer (kL/km).

First, let's calculate the fuel consumption rate per kilometer:

Fuel consumption rate (kL/km) = (Fuel consumption rate (gal/hr) * Conversion factor) / Distance (km)

Conversion factor: 1 gallon = 0.00378541 kiloliters

Distance: 2000 km

Fuel consumption rate (kL/km) = (2000 gal/hr * 0.00378541 kL/gal) / 2000 km

Fuel consumption rate (kL/km) = 3.78541 kL/km

Now, let's calculate the fuel saved during a typical 2000 km trip:

Fuel saved (kL) = (Fuel consumption rate before - Fuel consumption rate after) * Distance

Fuel consumption rate before: 3.78541 kL/km

Fuel consumption rate after: 2 kL/km

Distance: 2000 km

Fuel saved (kL) = (3.78541 kL/km - 2 kL/km) * 2000 km

Fuel saved (kL) = 1.78541 kL/km * 2000 km

Fuel saved (kL) = 3570.82 kL

Therefore, approximately 3570.82 kiloliters of fuel are saved in a typical 2000 km trip.

Answer:

F = 39.2 N   (hand force) and    N = 68.6 N (shoulder force)

Explanation:

In this exercise we must use the rotational and translational equilibrium conditions, we have several forces: the weight (W) of the pole applied at its geometric center, the load (w1) at one end, the shoulder support (N) 60 cm from the load and hand force (F) at the other end of the pole

Let's set the reference system at the fit point of the shoulder

     ∑ τ = 0

We will assume that the counterclockwise turns are positive

    w₁ 0.60 + W 0.1 + F₁ 0 - F 0.4 = 0

all distances are measured from the support of the man (x₀ = 0.60 m)

    F = (w₁ 0.60 + W 0.1) / 0.4

    F = (m₁ 0.6 + m 0.1) g / 0.4

let's calculate

    F = (2.6 0.6 + 0.4 0.1) 9.8 / 0.4

    F = 39.2 N

this is the force that the hand must exert to keep the system in balance

We apply the translational equilibrium condition

    -w₁ -W + N - F = 0

     N = w₁ + W + F

     N = (m₁ + m) g + F

let's calculate

     N = (2.6 + 0.4) 9.8 + 39.2

     N = 68.6 N
