From the diagram The value of cos C × sin A = $\frac{3}{4}$

<h3>Determine the numerical value of cos C × sin A</h3>

First step : determine the values of cos C and sin A

cos C = adjacent / hypotenuse

= a / b

= $\sqrt{3} / 2$

= √3/2

sin A = sin 60⁰

= √3/2

Therefore the numerical value of cos C * sin A = $\frac{3}{4}$

In conclusion From the diagram The value of cos C × sin A = $\frac{3}{4}$

You are moving into an apartment and take the elevator to the 6th floor. Suppose your weight is 660 N and that of your belonging

Ivan

Answer:

Explanation:

Total weight

My weight+weight of belongings

660+1100=1760N.

a. Work done by the elevator to travel a total height of 15.2m

Using newton law of motion

ΣF = ma

There are only two forces acting upward, the weight and the reaction by the elevator

Also note it is moving at constant velocity then, a=0

N - W=0

Then, N=W

N=1760N

So, workdone is given as

Wordone, =force × distance

Work done=1760×15.2

W=26,752J

W=26.752KJ

b. Work done on me alone is still need to go through the same process but will remove the weight of the belonging

Therefore,

Weight now = 660N

And using the same equation of motion

ΣF = ma

Comstant velocity, a=0

N - W=0

N=W

N=660N

Then, workdone

W=F×d

W=660×15.2

W=10,032J

W=10.032KJ

You plan to throw stones by using a sling that you whirl over your head. You will whirl the stone in a horizontal circle with a

MariettaO [177]

Answer:

$330.635$ meter per second square

Explanation:

Given

Height ,h $= 2.50$ m

Radius, r $= 1.50$ m

Distance travelled, $d = 15.9$ m

Since, the stone is released and it falls towards the sky, its initial velocity is zero

As per equation

$h = ut + \frac{1}{2} gt^2\\$ , we will evaluate "t"

Substituting the given values in above equation, we get

$2.5 = 0 *t + 0.5 * 9.81 * t^2\\t^2 = \frac{2.5}{0.5*9.81}\\ t = \sqrt{0.5096} \\t = 0.714$

Velocity

$= \frac{d}{t} \\= \frac{15.9}{0.714}\\= 22.27$

centripetal acceleration

$= \frac{v^2}{r} \\= \frac{22.27^2}{1.5}\\ = 330.635\\$

FM radio stations use different frequencies. For

Ratling [72]

Answer:

89.5 Hz

Explanation:

The relationship between the frequency and the wavelength is given by the following formula:

$\lambda = \frac{c}{f}\\\\$

where,

f = frequency

c = speed of light

λ = wavelength

Since the speed of light is constant. Therefore the formula suggests an inverse relationship between the frequency and the wavelength. Hence, the station with the lowest frequency will have the longest wavelength.

Therefore, the answer is:
