Answer:

The x and y components of the 500 N-force are 321.394 newtons and 383.023 newtons, respectively.

Explanation:

At first we present a figure describing the situation explained on statement, the x and y components of the force are determined by the following trigonometric expressions:

F_{x} = F\cdot \cos \alpha (1)

F_{y} = F\cdot \sin \alpha (2)

Where:

F - Magnitude of the force, measured in newtons.

\alpha - Direction of the force above the horizontal surface, measured in sexagesimal degrees.

If we know that F = 500\,N and \theta = 50^{\circ}, then the components of the force is:

F_{x} = (500\,N)\cdot \cos 50^{\circ}

F_{x} = 321.394\,N

F_{y} = (500\,N)\cdot \sin 50^{\circ}

F_{y} = 383.023\,N

The x and y components of the 500 N-force are 321.394 newtons and 383.023 newtons, respectively.

Dennis_Churaev [7]

Answer:

82.3 J

Explanation:

PE = mgh

PE = (2.80 kg) (9.8 m/s²) (3.00 m)

PE = 82.3 J

Compared to yellow light,orange light has
ArbitrLikvidat [17]
<span>So we wonder how can we compare yellow and orange light. Light is a small art of electromagnetic spectrum which is a continuum of all electromagnetic waves arranged by wavelenght and frequency. So on the EM spectrum orange has greaterr wavelangth than yellow but smaller frequency because wavelength and frequency are connected by the equation: c=f*lambda, where lambda is the wavelength and c is the speed of light and f is the frequency. We see that the higher the frequency the smaller the wavelength and vice versa.</span>

An inductor is connected to an AC generator. As the generator's frequency is increased, the current in the inductor A. Increases
Luda [366]

Answer:

B) Decrease

Explanation:

Resistance offered due to inductor in any AC circuit is given as

X_L = \omega L

here we know that

\omega = angular frequency

\omega = 2\pi f

now by ohm's law we know that

i = \frac{V}{X}

here we have

i = \frac{V}{\omega L}

so current is inversely depends on the frequency of AC

so if frequency is increased then the current will decrease

Suppose the ski patrol lowers a rescue sled carrying an injured skier, with a combined mass of 97.5 kg, down a 60.0-degree slope
Kitty [74]

a. 1337.3 J work, in joules, is done by friction as the sled moved 28 m along the hill.

b.21,835 J work, in joules, is done by the rope on the sled this distance.

c. 23,170 J   the work, in joules done by the gravitational force on the sled d. The net work done on the sled, in joules is 43,670 J.

       

<h3>What is friction work?</h3>

The work done by friction is the force of friction times the distance traveled times the cosine of the angle between the friction force and displacement

a. How much work is done by friction as the sled moves 28m along the hill?

ans. We use the formula:

friction work = -µ.mg.dcosθ

  = -0.100 * 97.5 kg * 9.8 m/s² * 28 m * cos 60

= -1337.3 J

-1337.3 J work, in joules, is done by friction as the sled moved 28 m along the hill.

b. How much work is done by the rope on the sled in this distance?

We use the formula:

Rope work = -m.g.d(sinθ - µcosθ)

rope work = - 97.5 kg * 9.8 m/s² * 28 m (sin 60 – 0.100 * cos 60)

                     = 26,754 (0.816)

                     = 21,835 J

21,835 J work, in joules, is done by the rope on the sled this distance.

c.  What is the work done by the gravitational force on the sled?

By using  the formula:

Gravity work = mgdsinθ

                    = 97.5 kg * 9.8 m/s² * 28 m * sin 60

                    = 23,170 J

23,170 J   the work, in joules done by the gravitational force on the sled .

       

D. What is the total work done?

By adding all the values

work done =  -1337.3 + 21,835 + 23,170

                 = 43,670 J

The net work done on the sled, in joules is 43,670 J.
