Answer:

\(n=7.05\times 10^9\) waves

Explanation:

Given that,

A wave oscillates with a period of \(4.25\times 10^{-10}\ s\)

We need to find the number of waves that will strike a signal detector in 3 seconds.

We know that,

Frequency = (no. of oscillations)/time

Time period = time/(no. of oscillations)

Let there are n waves that will strike

Explanation:

The acceleration of the eraser is 169.19 m/s².

A body travelling in a circle has centripetal acceleration. Due to the fact that velocity is a vector quantity (i.e., it has both a magnitude and a direction), when a body travels in a circle, its direction is continually changing, which causes a change in velocity, which results in an acceleration.

Given that angular velocity of the eraser: ω = 127 rpm

= 126×2π/60 radian/second

= 13.2 radian/second.

radius of the circle: r = 0.974 meter.

The answer is "1.0748 and 1.0875".

Explanation:

Please find the complete question in the attachment file.

The incidence angle is \(i=45^{\circ}\) for all colors When the angle is r, then use \(\frac{\sin{i}}{\sin{r}}=\frac{n_{o}}{n}\) . Snell's rule Where \(n_{o}\) is an outside material reflectance (same hue index) or n seems to be the crown glass index of the refraction, That index of inclination is \(90^{\circ}\) as the light in color shifted behaver from complete inner diffraction to diffraction.

Whenever the external channel has a thermal conductivity for the red light, that's also

\(n_{o}=\frac{n_{r}\sin{45^{\circ}}}{\sin{90^{\circ}}}=\frac{1.520\times\sin{45^{\circ}}}{\sin{90^{\circ}}}=1.0748\)

When outside the material has a refractive index, this happens with violet light.

\(n_{o}=\frac{n_{r}\sin{45^{\circ}}}{\sin{90^{\circ}}}=\frac{1.538\times\sin{45^{\circ}}}{\sin{90^{\circ}}}=1.0875\)

In point a, The only red light flows out from the leaned face and the residual colors are mirrored mostly on prism for the primary benefits \(n_{o}=1.0748\) (and slightly larger than that).

In point b, The only violet light is shown in the prism with the majority of the colors coming out from the sloping face for a scale similar to \(n_{o}= 1.0875\) (and slightly smaller than this).

The gazelle has zero average acceleration because it's moving at a constant speed. Constant speed means no change in speed means zero acceleration.

The cheetah, on the other hand, changes its speed from 0 m/min to 1820 m/min in a matter of 3 seconds, so its average acceleration is

a[ave] = (1820 m/min - 0 m/min) / (3 s)

… = (1820 m/min) / (3/60 min)

… = 36,400 m/min²

… = (36,400 m) / (60 s)²

… = 91/9 m/s² ≈ 10.1 m/s²

The power supplied by the boiler to heat the house is 25000 Watts(W) or 25 Kilowatts (KW).

Power is the rate of doing work. It is the energy supplied to the body per unit of time. It is of two types, instantaneous power which is calculated for a particular instant, and average power which is calculated over an interval of time Its S.I. unit is watts (W).

One watt is equal to one joule of energy transfered per second.

Given in the question

Energy transferred = 15 MJ

Time interval = 10 minutes

Before calculating the power, We need to convert the given values into their S.I. unit

1MJ = 1000000 J

So 15 MJ = 15 × 1000000 J

15 MJ = 15000000 J

Similarly,  1 minute = 60 seconds

So 10 minutes = 10 × 60 seconds

10 minutes = 600 seconds

Now,

Power =  Energy transferred/ Time Interval

Power = 15000000 / 600

Power = 150000/6

Power = 25000 Watts or W

Power = 25 kilowatts or KW

Therefore, the power supplied by the boiler to heat the house is 25000 Watts(W) or 25 Kilowatts (KW).

A) The force on a particle can be found by taking the negative of the derivative of the potential energy function with respect to x. For U = Ax^2 + Bsin(πx/L), let's find the derivative:

dU/dx = d(Ax^2)/dx + d(Bsin(πx/L))/dx = 2Ax + B(π/L)cos(πx/L)
Now let's find the force at x=0:
F(x=0) = -dU/dx(0) = -[2A(0) + B(π/L)cos(π(0)/L)] = -[0 + B(π/L)] = -B(π/L)
B) The force on the particle at x=L/2:
F(x=L/2) = -dU/dx(L/2) = -[2A(L/2) + B(π/L)cos(π(L/2)/L)] = -[AL + B(π/L)cos(π/2)] = -[AL + 0] = -AL
C) The force on the particle at x=L:
F(x=L) = -dU/dx(L) = -[2A(L) + B(π/L)cos(π(L)/L)] = -[2AL + B(π/L)cos(π)] = -[2AL - B(π/L)]

Using conservation of momentum

5(4)  + 1(0)   = (4+1) v

The average force acting on the billiard ball during the 4.0 ms time interval is 1590 Newtons.

To calculate the average force acting on the billiard ball during the given time interval, we can use Newton's second law of motion:

F = m * Δv / Δt

Where:

F is the average force,

m is the mass of the ball (0.53 kg),

Δv is the change in velocity (final velocity - initial velocity),

Δt is the time interval (4.0 ms).

Given that the initial velocity (vᵢ) is 0 m/s (since the ball is initially at rest) and the final velocity (v) is 12 m/s, we can calculate the change in velocity:

Δv = v - vᵢ = 12 m/s - 0 m/s = 12 m/s

Δt = 4.0 ms = 4.0 x 10⁻³ s

Now, we can substitute the values into the formula to calculate the average force:

F = (0.53 kg * 12 m/s) / (4.0 x 10⁻³ s)

F = (6.36 kg·m/s) / (4.0 x 10⁻³ s)

F ≈ 1590 N

The time rate of increase of pressure in the reservoir at this instant is approximately 9.56 Pa/s.

To calculate the time rate of increase of pressure in the reservoir, we can use the Ideal Gas Law:
PV = nRT

where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature. We can rearrange this equation to find n:
n = PV / RT

Since air is being pumped into the reservoir at a rate of 1 kg/s, we can convert this mass flow rate to a molar flow rate using the molar mass of air (M_air = 28.97 g/mol or 0.02897 kg/mol):

Molar flow rate = mass flow rate / molar mass

Molar flow rate = 1 kg/s / 0.02897 kg/mol

Molar flow rate ≈ 34.51 mol/s

Now, we can find the time rate of increase of moles in the reservoir:
dn/dt = 34.51 mol/s

Next, let's differentiate the Ideal Gas Law with respect to time:
d(PV)/dt = R * d(nT)/dt
Since V and T are constants, we get:
dP/dt = R * dn/dt / V

Substituting the values:
dP/dt = (8.314 J/mol*K) * (34.51 mol/s) / (30 m³)
dP/dt ≈ 9.56 Pa/s
At this instant, the time rate of increase of pressure in the reservoir is approximately 9.56 Pa/s.

A fuel-filled rocket is at rest. It burns its fuel and expels hot gas. The gas has a momentum of 1,500 kg m/s backward. So, The momentum of the rocket is -1500 kg m/s.

According to the law of conservation of momentum, in a closed system, the total momentum before and after a process remains constant.

A fuel-filled rocket that is initially at rest expels hot gas as it burns its fuel. The gas has a momentum of 1500 kg m/s backward.

We are required to determine the momentum of the rocket.

Consider the fuel-filled rocket as a system.

We have: Momentum before the burn = 0 kg m/s (since the rocket was at rest initially)Momentum after the burn = momentum of the expelled gas

We can therefore say that the initial momentum of the system was zero (0), and after the burn, the total momentum of the system remains the same as the momentum of the expelled gas.

Therefore: Momentum of rocket = - momentum of expelled gas

The negative sign signifies that the rocket's momentum is in the opposite direction of the expelled gas.

Hence, the momentum of the rocket is -1500 kg m/s.

Service-entrance conductors are conductors between the service point and the primary disconnect of a structure or power source conduit system. The service point refers to the point of the property where the utility's system ends and the customer's electrical system begins. Service-entrance conductors are commonly seen in residential homes or commercial buildings.

Service-entrance conductors that are rated 1000 are those that can handle a current capacity of 1000 amperes. These service-entrance conductors are important as they transmit electric power from the utility's point of connection to the primary electrical panel, where it is then distributed throughout the building or house. PVC, Type NM Cable, and Type MC Cable are permitted wiring methods for service-entrance conductors rated 1000.

ENT, on the other hand, is not allowed as a wiring method for service-entrance conductors rated 1000.ENT or Electrical Non-Metallic Tubing is a flexible plastic conduit made of polyvinyl chloride, which is used for indoor and outdoor applications.

Answer:

345.60N

Explanation:

The magnitude of the force parallel to the ramp that will push the box up the ramp are the frictional force(Ff) and the moving force Fm

Total force = Ff + Fm

Ff = ηR

Ff = ηmgcosθ

Fm = Wsinθ

Fm = mgsinθ

Total force = ηmgcosθ + mgsinθ

Total force = mg(ηcosθ + sinθ)

Given

mass m = 71kg

acceleration due to gravity g = 9.8m/s²

angle of inclination θ = 16°

coefficient of friction η = 0.23

Substitute into the formula;

Total force = 71(9.8)(0.23cos16 + sin16)

Total force = 695.8(0.2211+0.2756)

Total force = 695.8(0.4967)

Total force = 345.60N

Hence the magnitude force parallel to the ramp that you should push on the box so that it moves up the ramp at a constant speed is 345.60N

A wave's period is the amount of time it takes for two crests to pass one wavelength apart at a certain location.

The formula for wave period is wavelength divided by velocity since the periods indicate that a wave's period is the inverse of its frequency. The frequency of a wave is measured in 1/s, often known as Hertz, whereas the period of a wave is measured in seconds (s) (Hz).

Each wave, period is typically expressed in seconds. Speed (V) divided by wavelength (V) yields the period (T) (S). Divide the length by the speed, for instance, 12 m divided by 6 m/s = 2 s to determine the period of a wave with a speed of 6 m/s and a wavelength of 12 m.
