The frequency and period of the hummingbird's wing flutter are 80 Hz and 0.0125 s respectively.

It can be defined as the number of flutter per second. The period is the time taken to complete a flutter.

Given here,

Hummingbirds can flutter wings 4800 times /minute.

The frequency of the wing flutter,

\(f = \dfrac {4800}{60}\\\\ f = 80 \rm \ Hz \ (times/s)\)

Period of the wing flutter,

\(P = \dfrac 1f\)

Now put the value in the formula,

\(P = \dfrac 1{80}\\\\ P = 0.0125\rm\ s\)

Therefore, the frequency and period of the hummingbird's wing flutter are 80 Hz and 0.0125 s respectively.

Answer:

Clockwise

Explanation:

To determine the direction of the current induced in the conducting bar moving in a constant magnetic field, you can apply the "right-hand rule." Here's how:

1. Place your right hand in the same direction as the magnetic field with your fingers extended.

2. Your thumb points in the direction of the bar's motion (in this case, to the left).

3. Your palm faces the direction of the current flow.

Given that the magnetic field direction is not provided, I’ll assume it's pointing out of the plane of the screen/page (towards you). In this case, as you follow the right-hand rule:

1. Point your fingers towards yourself, representing the magnetic field.

2. Place your thumb pointing to the left, representing the direction of the bar's motion.

3. Your palm should be facing down, which means the current direction is counterclockwise.

So, in this case, the direction of the induced current would be counterclockwise. If the magnetic field direction is reversed (into the plane), then the induced current would be clockwise.

Water flowing out of an enclosed basin due to the tides is called a tidal outflow. Tidal outflows occur when the level of the water in the basin is higher than the level of the water outside, causing the water to flow out to the lower sea level.

This phenomenon is commonly observed in areas with narrow inlets or channels, where the tides can create a significant difference in water levels between the basin and the ocean. Tidal outflows are important ecological processes that affect the movement of nutrients and sediment in coastal ecosystems, and they can also impact the local climate and water quality.
Water flowing out of an enclosed basin due to the tides is called an ebb current. Ebb currents occur during the falling tide phase when water levels recede and flow back into the ocean. This process is a vital part of tidal dynamics, as it regulates water levels in coastal areas and contributes to the overall movement of water in our planet's oceans. Understanding ebb currents and their counterpart, flood currents (which occur during rising tides), is essential for navigation, coastal management, and marine ecosystem preservation.

Answer:

The truck must travel at a speed of 98.6677 km/hr to stay beneath the airplane

Explanation:

The given parameters are;

The velocity of the airplane, v = 105 km/hr

The direction of the airplane, θ = 25 degrees to the ground = 25°

Therefore, we have that the horizontal component of the velocity of the plane, vₓ is given as follows;

vₓ = v × cos(θ) = 105 km/hr × cos(25) ≈ 98.6677 km/hr

The vertical component of the velocity of the plane, \(v_y\), is given as follows;

\(v_y\) = v × sin(θ)  = 105 km/hr × sin(25) ≈ 44.37 km/hr

The truck only has to travel at a speed equal to the horizontal velocity of the airplane to stay beneath the airplane

Therefore, the travelling speed the truck must be vₓ which is 98.6677 km/hr to stay beneath the airplane.

Answer:  

Explanation:

at first the rock is at rest so initial velocity is zero
after accelerating it reaches a final velocity
we are supposed to find that final velocity


\(v^{2} = u^{2} +2ax\)
v= final velocity
u= initial velocity
x= distance
a= acceleration

\(v^{2} = 0^{2} + 2(9.8)(14.4)\)
\(v^{2} = 282.24\)
\(v= \sqrt{282.24}\)
\(v= 16.8 m/s\)

In order to find the time it takes, first let's convert the distance from miles per hour to feet per second: calculate the acceleration using Torricelli's equation

Then, let's :

Now, we calculate the time with the formula below:

Therefore the time required is 1.7 seconds.

Answer:

The value of \(a\cdot b\times c\) is 0.

Explanation:

The three vectors provided are:

\(a=2i-3j+7k\\b= i+2k\\c=j-k\)

The value to be computed is:

\(a\cdot b\times c\)

Compute the value of (b × c) as follows:

\(b\times c=\left|\begin{array}{ccc}i&j&k\\1&0&2\\0&1&-1\end{array}\right|\)

       \(=\left|\begin{array}{cc}0&2\\1&-1\end{array}\right|i-\left|\begin{array}{cc}1&2\\0&-1\end{array}\right|j+\left|\begin{array}{cc}1&0\\0&1\end{array}\right|k\\\\=-2i+1j+1k\)

Now compute the value of \(a\cdot b\times c\) as follows:

\(a\cdot b\times c=(2i-3j+7k)\cdot (-2i+j+k)\)

           \(=(2\cdot -2)+(-3\cdot 1)+(7\cdot1)\\\\=-4-3+7\\\\=0\)

Thus, the value of \(a\cdot b\times c\) is 0.

Answer:

The value of acceleration due to gravity is independent of mass of the body.

Explanation:

Let us consider the mass of the object as m and mass of earth as M

Therefore, force between the object and earth would be given by: F = GMm/d²

This force is equal to the weight of the object, i.e. mg

Thus;

mg = GMm/d²

g = GM/d²

Therefore, the value of acceleration due to gravity is independent of mass of the body.

Slapping a chicken, regardless of the force applied, will not cook it. Cooking requires sustained heat to raise the internal temperature of the chicken to a safe level for consumption.

Cooking involves the application of heat over a period of time to raise the internal temperature of food, ensuring that it reaches a safe level to kill any bacteria or pathogens present. Slapping a chicken, even at high speeds, does not provide the necessary sustained heat required for cooking.

To properly cook a chicken, various cooking methods are used, such as roasting, grilling, frying, or boiling. These methods involve exposing the chicken to a controlled heat source for a sufficient duration. The heat allows the chicken to cook evenly and reach the recommended internal temperature of at least 165°F (74°C) to ensure it is safe to consume.

It's important to follow proper cooking techniques and guidelines to ensure food safety and achieve desirable results. Slapping a chicken, while it may result in physical impact or tenderizing the meat, does not provide the necessary cooking conditions to render the chicken safe, delicious, and suitable for consumption.

The mass of the whole cookie is not directly important to this experiment.

In this experiment, the key variables involved are the rate of acceleration/deceleration and the time it takes for the train or cookie to reach certain speeds or come to a stop.

These variables depend on factors such as the applied force and the friction between the train or cookie and its surroundings. The mass of the whole cookie itself does not directly affect these variables.

Explanation:

(a) The efficiency of the transformer when it delivers full load at 0.46 power factor lagging can be calculated using the formula:

Efficiency = (Output Power / Input Power) x 100%

The output power can be determined by multiplying the apparent power by the power factor, and the input power is the sum of the core losses and copper losses. By substituting the given values, the efficiency can be computed.

(b) The percent of the rated load at which the transformer efficiency is a maximum can be determined by finding the load level that minimizes the sum of the core losses and copper losses. This can be achieved by varying the load and calculating the total losses until the minimum value is obtained.

(c) To determine the efficiency at the "optimal" load with a power factor of 0.9, the same approach as in part (a) can be used. The output power is calculated by multiplying the apparent power by the power factor, and the input power is the sum of the core losses and copper losses.

(d) The all-day efficiency of the transformer can be found by calculating the weighted average of the efficiencies during each load cycle, considering the duration and power factor of each load condition. By multiplying the efficiency of each load cycle by its corresponding duration and summing them up, the all-day efficiency can be obtained.

To provide a detailed explanation and calculations for each part, I would need the specific numerical values for the apparent power, power factor, load durations, and load power factors. Please provide those values, and I can assist you in solving the problem step by step.
