Answer: hey!

youre answer is

In order to meet up at the trailing edge, the molecules going over the top of the wing must travel faster than the molecules moving under the wing. Because the upper flow is faster, then, from Bernoulli's equation, the pressure is lower. The difference in pressure across the airfoil produces the lift.

Airplane wings are shaped to make air move faster over the top of the wing. When air moves faster, the pressure of the air decreases. So the pressure on the top of the wing is less than the pressure on the bottom of the wing. The difference in pressure creates a force on the wing that lifts the wing up into the air.

Bernoulli's Principle, states that pressure decreases when air moves faster. Air moves faster over the top of a wing, which results in an area of lower pressure. Meanwhile, the bottom of the wing experiences higher pressure. Camber increases the difference in air pressure between the top and bottom surfaces.

Answer:

\(\boxed {\boxed {\sf 12 \ Newtons }}\)

Explanation:

Force is equal to the product of mass and acceleration.

\(F=m*a\)

We know the mass, but not the acceleration. Therefore, we must calculate it before we can calculate force.

1. Calculate Acceleration

Acceleration is the change in velocity over the change in time.

\(a=\frac{V_f-V_i}{t}\)

The final velocity is 10 meters per second and the initial velocity is 4 meters per second. The time is 1 second.

\(V_f=10 \ m/s \\V_i= 4 \ m/s \\t= 1 \ s\)

Substitute the values into the formula.

\(a=\frac{10 \ m/s-4 \ m/s }{1 \ s}\)

Solve the numerator.

\(a=\frac{6 \ m/s}{1 \ s }\)

Divide.

\(a= 6 \ m/s/s=6 \ m/s^2\)

2. Calculate Force

Now we know the acceleration and the mass.

\(m= 2 \ kg \\a= 6 \ m/s^2\)

Substitute the values into the fore formula.

\(F= 2 \ kg * 6 \ m/s^2\)

Multiply.

\(F= 12 \ kg*m/s^2\)

\(F= 12 \ N\)

The force applies to the ball was 12 Newtons.

The formula for net torque is T=flsinФ which is the cross product of perpendicular force multiplied by distance.

When displaced from equilibrium, the system experiences a net force or torque in a direction opposite to the direction of the displacement. Equilibrium is independent of displacement from its original position

Energy is conserved so same amount of energy with or without machine Angular Momentum conserved if net external torque is zero Linear Momentum conserved if net external force is zero. Kinetic Energy conserved if elastic collision.

The first condition necessary to achieve equilibrium is the one already mentioned: the net external force on the system must be zero. Expressed as an equation, this is simply net F = 0 but Note that if net F is zero, then the net external force in any direction is zero. For example, the net external forces along the typical x- and y-axes are zero.

With sinusoidal-steady-state excitation, a purely resistive circuit has voltage and current phasors that are in phase with each other. This means that the voltage and current waveforms reach their maximum and minimum values at the same time.

To understand this concept, let's consider an example. Imagine a circuit with a resistor connected to an AC voltage source. When the voltage source reaches its peak positive value, the current flowing through the resistor is also at its peak positive value. Similarly, when the voltage source reaches its peak negative value, the current is at its peak negative value. The voltage and current waveforms have the same frequency and shape, but they are shifted by a phase angle of 0 degrees.

In terms of phasors, a purely resistive circuit has a voltage phasor and a current phasor that are aligned on the same axis, indicating that they have the same magnitude and phase. This can be represented by a single phasor diagram where the length of the phasor represents the magnitude of the voltage or current.

Answer:

(B) 13.9 m

(C) 1.06 s

Explanation:

Given:

v₀ = 5.2 m/s

y₀ = 12.5 m

(A) The acceleration in free fall is -9.8 m/s².

(B) At maximum height, v = 0 m/s.

v² = v₀² + 2aΔy

(0 m/s)² = (5.2 m/s)² + 2 (-9.8 m/s²) (y − 12.5 m)

y = 13.9 m

(C) When the shell returns to a height of 12.5 m, the final velocity v is -5.2 m/s.

v = at + v₀

-5.2 m/s = (-9.8 m/s²) t + 5.2 m/s

t = 1.06 s

For the seagull that is ascending straight upward at 5.2 m/s and drops a shell when it is 12.5 m above the ground, we have:

A) The acceleration of the shell right after it is released is given by the acceleration due to gravity = 9.81 m/s².  

B) The maximum height above the ground reached by the shell is 13.9 m.  

C) The time for the shell to return to a heigh of 12.5 m above the ground is 1.06 s.

A) Since the shell is dropped, the acceleration after it is released is the same at each point of height as it falls, so the acceleration of the shell is:

\( g = 9.81 m/s^{2} \)

Where g is the acceleration due to gravity

Hence, the acceleration of the shell is 9.81 m/s²

B) The maximum height reached by the shell can be calculated with the following equation:

\( h_{max} = h_{i} + h_{f} \)   (1)

Where:

\( h_{i} \): is the initial height = 12.5 m

\( h_{f} \): is the final height

The final height is the height reached by the shell after it is released. It can be calculated with the next equation:

\( v_{f}^{2} = v_{i}^{2} - 2gh_{f} \)   (2)

Where:

\( v_{f}\): is the final velocity = 0 (in the maximum height)

\( v_{i}\): is the initial velocity = 5.2 m/s

\(h_{f}\): is the height reached by the shell after it is released

The final heigh is (eq 2):

\( h_{f} = \frac{v_{i}^{2}}{2g} = \frac{(5.2 m/s)^{2}}{2*9.81 m/s^{2}} = 1.4 m \)

Now, the maximum height is (eq 1):

\( h_{max} = h_{i} + h_{f} = 12.5 m + 1.4 m = 13.9 m \)

Then, the maximum height reached by the shell is 13.9 m.

C) The time for the shell to go from the maximum height to 12.5 m (falling time) can be calculated with:

\(y_{f} = y_{i} + v_{i}t - \frac{1}{2}gt^{2}\)

Where:

\(v_{i}\): is the initial velocity in its way down = 0 (it is going free fall)

\( y_{f} \): is the final height = 12.5 m  

\( y_{i} \): is the initial height = 13.9 m (maximum height)

The falling time is:

\(12.5 m = 13.9 m + 0 - \frac{1}{2}9.81 m/s^{2}*t_{f}^{2}\)  

\(t_{f} = \sqrt{\frac{2*(13.9 m - 12.5 m)}{9.81 m/s^{2}}} = 0.53 s\)

Now, the time to return to 12.5 is twice the above time (time to go up plus the time to go down).  

\( t = 2*t_{f} = 2*0.53 s =  1.06 s \)

Therefore, the time for the shell to return to a height of 12.5 m is 1.06 s.

To determine how far from a bus stop the bus should start to slow down, we need to consider the bus's deceleration and the desired speed when reaching the bus stop. Let's assume the bus needs to slow down to a speed of 10 km/h when it reaches the bus stop.

First, we need to calculate the deceleration of the bus. Let's say the deceleration is -2 m/s² (negative sign indicating deceleration). To convert this into km/h², we can use the conversion factor: 1 km/h² = 0.27 m/s². Next, we need to calculate the time it takes for the bus to decelerate from 36 km/h to 10 km/h. Using the formula: acceleration = (final speed - initial speed) / time, we can rearrange it to solve for time: time = (final speed - initial speed) / acceleration.

Applying the values, we get: time = (10 km/h - 36 km/h) / (-2 km/h²) = 13 seconds. Finally, we can calculate the distance traveled during this deceleration period using the formula: distance = initial speed * time + (1/2) * acceleration * time². Plugging in the values, we get: distance = 36 km/h * 13 seconds + (1/2) * (-2 km/h²) * (13 seconds)². Simplifying the equation, we find that the bus should start slowing down about 702 meters (or 0.702 km) from the bus stop. Therefore, the bus should start to slow down about 702 meters from the bus stop to reach a speed of 10 km/h when it arrives.

The induced magnetic field strength 9.5cm radially outward from the center of the plates is  821.052 Tesla.

We know very well that when a charge is moving with some speed in particular direction then, it will induce a magnetic field around its environment. Only moving charge is able to produce magnetic field, stationary charge only produce electric field.

We know that magnetic field is given by=(μ/2πr)×(q/t) where

μ is called as magnetic field constant,

q is the induced charge in the capacitor,

and r is the distance between the two plates

So, we have r=9.5cm=0.095m,(q/t) =39C/sec and μ=4π×10⁻⁷Tesla-m/A.

So, on putting the above values, we get

=>B=(4π×10⁻⁷ × 39)/2π×0.095

=>B=2×39/ 0.095

=>B=78/0.095

In projectile,

Maximum height = \(\frac{u^{2}sin^{2} \theta }{2g}\) and range = \(\frac{u^{2}sin2\theta }{g}\)

u = velocity of the body

\(\theta\) = angle of launch

g = acceleration due to gravity

If the range equals the maximum height in an ideal projectile launch on a horizontal plane, this means;

\(\frac{u^{2}sin^{2} \theta }{2g} = \frac{u^{2}sin2\theta }{g}\)

since \(sin2\theta = 2sin\theta cos\theta\)

\(\frac{u^{2}sin^{2} \theta }{2g} = \frac{u^{2}2sin\theta cos\theta }{g}\\\frac{sin\theta}{2} =2cos\theta \\sin\theta = 4cos\theta\\\frac{sin\theta}{cos\theta} = 4\\tan\theta = 4\\\theta = tan^{-1} \\4\theta = 75.9^{0}\)
