Answer:

Centrifugal force = 1230.77 Newton.

Explanation:

The force associated with the car is generally referred to as centrifugal force and it can be calculated using the formula;

Centrifugal force = mv²/r

Given the following data;

Mass = 800kg

Radius = 65m

Velocity = 10m/s

To find the force;

Centrifugal force = (800*10²)/65

Centrifugal force = (800*100)/65

Centrifugal force = 80000/65

Centrifugal force = 1230.77 Newton.

Answer:

I = 1.09 A

Explanation:

Here, 5 ohm and 12 ohm resistor are connected in parallel. Using the parallel combination of resistors as follows :

[tex]\dfrac{1}{R}=\dfrac{1}{R_1}+\dfrac{1}{R_2}\\\\\dfrac{1}{R}=\dfrac{1}{5}+\dfrac{1}{12}\\\\ R=3.52\ \Omega[/tex]

Now R and 2 ohm resistors are in series. Let the equivalent be [tex]R_{eq}[/tex]. So,

[tex]R_{eq}=3.52+2\\\\=5.52\ \Omega[/tex]

Let I be the current. Using Ohm's law,

V = IR

[tex]I=\dfrac{V}{R_{eq}}\\\\I=\dfrac{6}{5.52}\\\\I=1.086\ A[/tex]

or

I = 1.09 A

So, the correct option is (c).

Answer:

a. Constructive interference.

b. [tex]0.34\; \rm m[/tex].

c. [tex]0.68\; \rm m[/tex].

d. [tex]1.02\; \rm m[/tex].

Explanation:

Frequency of this sound wave: [tex]f = 250\; \rm Hz = 250\; \rm s^{-1}[/tex].

Speed of this sound wave: [tex]v = 340\; \rm m \cdot s^{-1}[/tex].

Calculate the wavelength of this sound wave:

[tex]\begin{aligned} \lambda &= \frac{v}{f} \\ &= \fraac{340\; \rm m \cdot s^{-1}}{250\; \rms^{-1}} \approx 1.36\; \rm m\end{aligned}[/tex].

Path difference refers to the absolute value of the difference between:

When the observer in this question is on the line between the two speakers at [tex]d[/tex] meters from the midpoint, the corresponding path difference would be [tex]2\; d[/tex] meters. (Add [tex]d\![/tex] to the distance from the closer source, and subtract [tex]d\!\![/tex] from the distance from the other source.)

The question states that sound from the two speakers are in-phase. In other words, at every instant, the sound wave from the two speakers are at the same phase at the position of each speaker.

Because wave from the two sources are in-phase at the source:

Path difference is [tex]0[/tex] when the observer is at the midpoint. That would correspond to constructive interference.

The first destructive interference (minimum intensity) corresponds to a path difference of [tex]\lambda / 2[/tex]. Along the line, that would be observed at [tex](1/2) \cdot (\lambda / 2) = 0.34\; \rm m[/tex] from the midpoint.

The next constructive interference (maximum intensity) would be observed when path difference is [tex]\lambda[/tex]. Along the line, that would be observed at [tex](1/2)\cdot \lambda = 0.68\; \rm m[/tex] from the midpoint.

The second destructive interference (minimum intensity) would be observed when path difference is [tex](1 + (1/2))\, \lambda[/tex]. Along the line, that would be observed at [tex](1/2) \cdot ((3/2)\cdot \lambda) = 1.02\; \rm m[/tex] from the midpoint.

Answer:

3.29 meters

Explanation:

c = λ f

c = speed of light = 3 * 10^8 m/s

λ = wavelength

f = frequency

3 * 10^8 m/s = λ * (9.13 * 10^7 1/s)

λ  = (3 * 10^8 m/s) / (9.13 * 10^7 1/s)

λ  = 3.29 m

Answer:

If a coil of wire is placed in a changing magnetic field, a current will be induced in the wire. This current flows because something is producing an electric field that forces the charges around the wire. (It cannot be the magnetic force since the charges are not initially moving). ... that determines the induced current.

The Forces of Flight

At any given time, there are four forces acting upon an aircraft.  

These forces are lift, weight (or gravity), drag and thrust. Lift is  

the key aerodynamic force that keeps objects in the air. It is the  

force that opposes weight; thus, lift helps to keep an aircraft in  

the air. Weight is the force that works vertically by pulling all  

objects, including aircraft, toward the center of the Earth. In order  

to fly an aircraft, something (lift) needs to press it in the opposite  

direction of gravity. The weight of an object controls how strong  

the pressure (lift) will need to be. Lift is that pressure. Drag is a  

mechanical force generated by the interaction and contract of a  

solid body, such as an airplane, with a fluid (liquid or gas). Finally,  

the thrust is the force that is generated by the engines of an  

aircraft in order for the aircraft to move forward.

A hanging 7.5 kg object stretches a spring 1.1 m, the spring constant of the spring is approximately 66.82 N/m.

Hooke's Law, which states that the force exerted by a spring is directly proportional to the displacement of the spring from its equilibrium position, can be used to compute the spring constant.

F = -k * x

Here, we have:

mass (m) = 7.5 kg,

displacement (x) = 1.1 m,

acceleration due to gravity (g) = 9.8 m/[tex]s^2[/tex].

We know that:

weight (W) = mass * acceleration due to gravity

So,

W = m * g

W = 7.5 kg * 9.8 m/[tex]s^2[/tex]

W = 73.5 N

F = W = 73.5 N

F = -k * x

73.5 N = -k * 1.1 m

Solving for k:

k = -73.5 N / 1.1 m

k ≈ 66.82 N/m

Thus, the spring constant of the spring is approximately 66.82 N/m.

Remark

The only thing that might trip you up is what to do with the angle. The vertical component of the 15 degrees does no work against anything. So the 15 degrees limits the horizontal force.

The formula is

Work = F * d * cos(15)

The givens are

F = 2000 N

d = 30 m

Cos(15) = 0.9659

Solution

Work = 2000 * 30 * cos(15)

Work = 57,955
