Answer:

The average linear velocity (inches/second) of the golf club is 136.01 inches/second

Explanation:

Given;

length of the club, L = 29 inches

rotation angle, θ = 215⁰

time of motion, t = 0.8 s

The angular speed of the club is calculated as follows;

[tex]\omega = (\frac{\theta}{360} \times 2\pi, \ rad) \times \frac{1}{t} \\\\\omega = (\frac{215}{360} \times 2\pi, \ rad) \times \frac{1}{0.8 \ s} \\\\\omega = 4.69 \ rad/s[/tex]

The average linear velocity (inches/second) of the golf club is calculated as;

v = ωr

v = 4.69 rad/s  x  29 inches

v = 136.01 inches/second

Therefore, the average linear velocity (inches/second) of the golf club is 136.01 inches/second

Answer:

I would need to see the part a to be more specific but this may help:

resources like solar, water, wind are considered renewable because they will never run out, they can be replenished over and over again. There will always be a sun (and if there wasn't then we'd have bigger conserns than renewable energy) and the wind will always blow. It can never run out because you use too much unlike coal and fossil fuels.

Hope this helps!

Answer:

Explanation:

Answer:

the observed frequency will reduce but the wavelength will increase

Explanation:

As we know

fo = fs (v/(v-vs))

fo = observed frequency

vs = velocity of source

As per this equation,  

When an observer moves away from the stationary source, the observed frequency reduces. Since the observer in the balloon is moving away from the source which itself is moving in opposite direction, the observed frequency will reduce.  

Since wavelength = V/fs . The source frequency is unchanged but the velocity is increasing as it is moving in downward direction. Hence, the wavelength will increase

kilogram is a fundamental unit because it is one of the 7 fundamental units that serve as a building block for derived units.

Explanation:

Fundamental units are used to measure fundamental quantities. They are fundamental units because they serve as a building block for derived units.

7 fundamental quantities and their corresponding units;

Length – meter

Mass – kilogram

Time - seconds

Temperature - Kelvin

Amount of substance - Moles  

Electric Current - Ampere  

Luminous intensity -  Candela

Thus, kilogram is a fundamental unit because it is one of the 7 fundamental units.

Answer: Hi your question is incomplete below is the complete question

A 2.0-m long rod has a density in kilograms per meters λ = a + bx, where a=1.0kg/m, b=1.0kg/m2, and x is the distance from the left end of the rod. The rod rests horizontally with each end supported by a scale. The force exerted by the left scale is?

answer : 13.08 N

Explanation:

Determine the force exerted by the left scale

Length of rod = 2.0 m

Density of rod ( λ )= a + bx = 1 + 1x

First step ; Determine the moment

∑ moment = 0 =  F * 2 - (( 1 * 2 * g * 2/2) + (1/2 * 2 * 1 * g * (2/3 ) )

∴ F = 4g / 3

     = 4 * 9.81 / 3 =  39.24 / 3 = 13.08 N

Answer:hi

Explanation:

Answer:

Explanation:

screen distance D = 6 m .

wavelength of light λ = 633 nm.

slit width = d .

Distance between first minima on either side is width of central maxima

= 2 x λD /d

Given

32 x 10⁻³ = 2 x λD /d

d = 2 x λD /32 x 10⁻³

= 2 x 633 x 10⁻⁹ x 6 / 32 x 10⁻³

= 237.37 x 10⁻⁶ m

= .23737 x 10⁻³ m

= .24 mm .

The block comes to a rest from 12 m/s with acceleration 3 m/s^2, which is carried out over a distance x such that

(12 m/s)^2 - 0^2 = 2 (3 m/s^2) x

=>   x = (12 m/s)^2 / (2 (3 m/s^2)) = 24 m

The force itself has a magnitude F such that

F = (4 kg) (3 m/s^2)

=>   F = 12 N

This force is pointing opposite the direction in which the block is moving, so the work it's performing is negative, and the work done is

W = - (12 N) (24 m) = -288 Nm = -288 J

which makes C the answer.

Answer:

interference is between destructive  and constructive

Explanation:

The interference of two sound waves periodicity in phase by the speakers is

          Δr = [tex]\frac{\phi }{2\pi } \ \lambda[/tex]

in this case they indicate that the frequency is f = 700 Hz, the wave speed is

            v =λ f

            λ = v / f

            λ = 341/700

            λ = 0.487 m

Let's use the Pythagorean theorem to find the distance that each wave travels

        r₁ = [tex]\sqrt{x^2 + y^2}[/tex]

let's measure the distance from speaker 1

          r₁ = [tex]\sqrt{5^2 + 1^2}[/tex]

          r₁ = 5,099 m

the distance from the second speaker

          r₂ = \sqrt{x^2 + y^2}

          r₂ = [tex]\sqrt{5^2 +3^2}[/tex]

          r₂= 5.831 m

the difference in the way is

          Δr = r₂ -r₁

          Δr = 5,831 - 5,099

          Δr = 0.732 m

         [tex]\frac{ \phi }{2\pi }[/tex] = Δr /λ

         \frac{ \phi }{2\pi } = 0.732 / 0.487

         \frac{ \phi }{2\pi } = 1.50

this is the phase difference this phase difference is approximately

            Ф= [tex]\frac{\pi }{2}[/tex] =1.57,

so the interference is between destructive ( Ф = π) and constructive (Ф=2π)

Answer:

[tex]81:256[/tex].

Explanation:

Let [tex]T[/tex] denote the absolute temperature of this object.

Calculate the value of [tex]T[/tex] before and after heating:

[tex]T(\text{before}) = 27 + 273 = 300\; \rm K[/tex].

[tex]T(\text{after}) = 127 + 273 = 400\; \rm K[/tex].

By the Stefan-Boltzmann Law, the energy that this object emits (over all frequencies) would be proportional to [tex]T^4[/tex].

Ratio between the absolute temperature of this object before and after heating:

[tex]\displaystyle \frac{T(\text{before})}{T(\text{after})} = \frac{3}{4}[/tex].

Therefore, by the Stefan-Boltzmann Law, the ratio between the energy that this object emits before and after heating would be:

[tex]\displaystyle \left(\frac{T(\text{before})}{T(\text{after})}\right)^{4} = \left(\frac{3}{4}\right)^{4} = \frac{81}{256}[/tex].

Explanation:

Let's propose the solution of this exercise, let's use the relationship between momentum and momentum

       I = Δp

       F t = m v_f - m v₀

indicates that the carriage stops v_f = 0

       F t = - m v₀

Therefore, if the impact time decreases, the force must increase and therefore the damages also

Car A collides with a concrete wall that is rigid, therefore the collision occurs in a very short time, car B collides with area, so the collision time is extended, now we can complete the sentences

1) Stunt Car A experiences a _HIGH IMPULSE_ over a SHORT INSTANT__ of time.

2)Stunt Car B experiences a _SMALL IMPULSE_____ over a _MORE INSTANT__ of time.

3) Because of the force experienced by Stunt Car A, it will sustain __MORE____ damage than Stunt Car B.a

Answer:

$ 0.077

Explanation:

We'll begin by calculating the equivalent resistance of the three 300 Ω resistors connected in series. This can be obtained as follow:

Equivalent resistance of the three 300 Ω (R₃₀₀) = 300 + 300 + 300

= 900 Ω

Next, we shall determine the equivalent resistance of the two 100 Ω resistors connected in series. This can be obtained as follow:

Equivalent resistance of the two 100 Ω (R₁₀₀) = 100 + 100

= 200 Ω

Next, we shall determine the equivalent resistance in the circuit. This can be obtained as follow:

Equivalent resistance of the three 300 Ω (R₃₀₀) = 900 Ω

Equivalent resistance of the two 100 Ω (R₁₀₀) = 200 Ω

Equivalent Resistance (R) =?

R = R₃₀₀ × R₁₀₀ / R₃₀₀ + R₁₀₀ (since they are in parallel connections)

R = 900 × 200 / 900 + 200

R = 163.64 Ω

Next, we shall determine the energy in KWh. This can be obtained as follow:

Voltage (V) = 10 V

Resistance (R) = 163.64 Ω

Time (t) for 30 days = 12 × 30 = 360 h

Energy (E) =?

E = V²t / R

E = 10² × 360 / 163.64

E = 100 × 360 / 163.64

E = 36000 / 163.64

E = 220 Wh

Divide by 1000 to express in KWh

E = 220 Wh / 1000 = 0.22 KWh

Finally, we shall determine the amount paid for 1 month (30 days). This can be obtained as follow:

Cost per KWh = $ 0.35

Energy (E) = 0.22 KWh

Cost for 30 days =?

Cost for 30 days = Energy × Cost per KWh

Cost for 30 days = 0.22 × 0.35

Cost for 30 days = $ 0.077

Therefore, the amount that must be paid for 1 month is $ 0.077
