What type of relationship (direct or inverse) exists between wave- length, frequency, and photon energy

Answer:

The time between the emission of the wave and it's reception was 0.4 seconds.

Explanation:

The sound wave emitted by the sonar traveled from the boat to the fishes and came back, therefore the distance of it's total route is twice the distance from the boat to the fishes. We can apply the average speed formula in order to solve this problem, this is done below:

\(\text{speed} = \frac{\text{distance}}{\text{time}}\)

We were given the distance traveled by the wave and it's speed, therefore we can solve for the time:

\(\text{time} = \frac{\text{distance}}{\text{speed}}\\\\\text{time} = \frac{(2*300)}{1500}\\\\\text{time} = \frac{600}{1500} = 0.4 \text{ s}\)

The time between the emission of the wave and it's reception was 0.4 seconds.

Answer:

D.Measurements made on these particles will be correlated.

Explanation:

If \(\vec A\) and \(\vec B\) are perpendicular, then their dot product is zero. This means

\(\vec A \cdot \vec B = (\vec\imath + 5\,\vec\jmath + n\,\vec k) \cdot (2\,\vec\imath - \vec\jmath + \vec k) = 2 - 5 + n = 0\)

Solving for n is trivial; it follows that n = 3.

When the first extension cord is replaced by the second then the voltage supplied to the appliance drops by 3.834 V.

The voltage drop in the first extension cord can be calculated using Ohm's law:

V = IR

where V is the voltage drop, I is current, and R is the resistance.

The voltage drop in the first extension cord is V = IR = (5.60 A) x (0.0760 Ω) = 0.4256 V.

The voltage drop across the second extension cord is also V = IR = (5.60 A) x (0.760 Ω) = 4.256 V.

Therefore, the voltage supplied to the appliance changes by (0.4256 V - 4.256 V) = - 3.8304 V when the first extension cord is replaced by the second.

Extension cords are useful for transferring power to areas where there are no outlets, and they can also come in handy in places where outlets are inaccessible. However, if you have two extension cords to choose from, the voltage drop in each cord can impact the amount of voltage supplied to the appliance.

The amount of current that leaves the battery will decrease when light bulb E is unscrewed and removed from the circuit. Based on the available information, we cannot determine whether bulb A gets brighter, dimmer, or stays the same brightness.

The reason is that there is not enough information about the circuit or the behavior of other bulbs in the circuit.

However, we are given a hint that the brightness of a light bulb is related to the square of the current that passes through it and the resistance of the bulb. This means that if the current passing through bulb A increases, its brightness will increase as well, and if the current passing through bulb A decreases, its brightness will decrease.

For part B, when light bulb E is unscrewed and removed from the circuit, the total resistance of the circuit will increase since there is now one less bulb for the current to flow through. According to Ohm's law, the current passing through the circuit is directly proportional to the voltage and inversely proportional to the resistance.

Since the voltage of the battery remains constant, the current passing through the circuit will decrease when the resistance of the circuit increases. Therefore, the amount of current that leaves the battery will decrease when light bulb E is unscrewed and removed from the circuit.

When the radius of a wheel is doubled, the answers to the given questions are affected in the following ways:

The angular speed at 2.00 s is smaller: False. Doubling the radius does not directly affect the angular speed at a specific time. It depends on the angular acceleration and initial conditions.

The angle rotated through from t = 0 to t = 2.00 s is the same: True. The angle rotated depends on the angular speed and time, which are not directly affected by the radius.

The angular speed at t = 2.00 s is greater: False. The angular speed is not affected by doubling the radius, assuming the angular acceleration remains constant.

The angular speed at t = 2.00 s is the same: True. Doubling the radius does not directly impact the angular speed at a specific time, assuming other factors remain constant.

The angle rotated through from t = 0 to t = 2.00 s is greater: False. The angle rotated depends on the angular speed and time, which are not directly influenced by the radius.

The angle rotated through from t = 0 to t = 2.00 s is smaller: False. The angle rotated depends on the angular speed and time, which are not directly affected by the radius.

Now, let's solve the provided problem. We are given that the wheel has a constant angular acceleration of 3.40 rad/s² and an angular speed of 1.70 rad/s at t = 0.

(a) To find the angle rotated between t = 0 and t = 2.00 s, we can use the equation: θ = ω₀t + (1/2)αt², where ω₀ is the initial angular speed, α is the angular acceleration, and t is the time. Substituting the given values, we get θ = (1.70 rad/s)(2.00 s) + (1/2)(3.40 rad/s²)(2.00 s)². Evaluating this expression gives us the angle rotated in radians.

(b) To find the angular speed at t = 2.00 s, we can use the equation: ω = ω₀ + αt. Substituting the given values, we get ω = 1.70 rad/s + (3.40 rad/s²)(2.00 s).

The conversion factor from horsepower to watts is 1 hp = 746 watts.

Therefore, the Ford Shelby GT 500's horsepower of 760 hp can be converted to watts as follows:

760 hp × 746 watts/hp = 567760 watts

To convert horsepower to watts, you simply need to multiply the number of horsepower by the conversion factor of 746 watts/hp.So, the numeric answer for 760 hp in watts is 567760.

According to the work-energy principle, the work done on an object is equal to the change in kinetic energy. Mathematically, the work-energy principle can be represented as follows:

W = ΔKHere, W represents the work done on the object, and ΔK represents the change in kinetic energy of the object.

The change in kinetic energy can be calculated using the following formula:

ΔK = (1/2)mvf² - (1/2)mvi²

Here, m represents the mass of the object, vi represents the initial velocity of the object, and vf represents the final velocity of the object. In this case, the object is initially at rest (vi = 0), so the formula can be simplified to

:ΔK = (1/2)mvf²

Now, we can use the following kinematic equation to calculate the final velocity of the object:

vf² = vi² + 2ax

Here, a represents the acceleration of the object, x represents the displacement of the object, and vi represents the initial velocity of the object. Plugging in the given values, we get:

vf² = 0 + 2(10 m/s²)(30 m - 10 m)vf² = 400 m²/s²vf = 20 m/s

Now, we can plug in the values of m and vf to calculate the change in kinetic energy:

ΔK = (1/2)(100 kg)(20 m/s)²ΔK = 20000 JSo, the numeric answer for the work done on the object is 20000 J.

Explanation:

The overestimated distance traveled between t=0 and t=5 is 158 meters.

To estimate the distance traveled, we can use the trapezoidal rule to approximate the area under the curve of the velocity function v(t). The trapezoidal rule divides the interval [0, 5] into subintervals with a width of 1 second and approximates each subinterval as a trapezoid. The formula for the trapezoidal rule is ∫[a,b] f(x) dx ≈ ∑[(i=1 to n)] [f(x_i-1) + f(x_i)] * Δx / 2, where Δx is the width of each subinterval.

Using this formula, we can calculate the overestimated distance traveled:

s ≈ [f(0) + 2f(1) + 2f(2) + 2f(3) + 2f(4) + f(5)] * Δt / 2

≈ [0 + 2(1^2 + 6) + 2(2^2 + 6) + 2(3^2 + 6) + 2(4^2 + 6) + (5^2 + 6)] * 1 / 2

≈ 158 meters.

A negative magnetic field reading indicates the magnetic field is in the opposite direction of the reference direction, while recording the absolute value removes the sign, focusing on the field's strength.

When using a physical probe to measure magnetic fields, a negative reading signifies that the direction of the magnetic field is opposite to the reference direction chosen. This occurs due to the nature of magnetic fields, which have both magnitude and direction. The procedure asks you to record the absolute value of the magnetic field because it is often more important to know the field's strength rather than its direction.

The absolute value eliminates the negative sign, providing a measure of the magnetic field's magnitude, regardless of its direction. This allows for better comparison and analysis of the magnetic field's strength in different locations or under various conditions, making it a more meaningful metric in many cases.

We can solve this problem using the principle of conservation of momentum. The force required to keep the tanker at rest is approximately 407.99 N, assuming no other forces are acting on the tanker.

The momentum of the water jet leaving the tanker is equal and opposite to the momentum of the tanker.

Let the mass of water leaving the tanker per second be m, then:

m = 85 dm³/s = 85 kg/s (since 1 dm³ = 1 L = 1 kg)

The velocity of the water jet leaving the tanker is v = 4.8 m/s.

The momentum of the water jet is p = mv = (85 kg/s)(4.8 m/s) = 408 kg m/s.

To keep the tanker at rest, an equal and opposite force must be applied. Therefore, the force required is:

F = Δp/Δt = p/t

Since the momentum is constant, we can use the given rate of discharge to find the time it takes to discharge one second's worth of water:

t = m/v = (85 kg/s)/(4.8 m/s) = 17.71 s

Therefore, the force required is:

F = p/t = (408 kg m/s)/(17.71 s) = 23.05 N

However, the question asks for the force required to keep the tanker at rest, which is the opposite of the force exerted by the water jet. Therefore, the force required is:

F = -23.05 ₓ17.7 = -407.99 N (rounded to two decimal places)
