Answer:

d = 2,998 10⁷ m

Explanation:

The speed of an electromagnetic wave is the speed of light

      c = 2,998 10⁸ m / s

This speed is in a vacuum, when the light is in a material medium, its speed is lower than this, even when the order of magnitude is maintained.

Since the speed of a wave is constant, we can use the kinematic relationship

       c = d / t

       d = c t

Let's calculate

      d = 2,998 108 0.1

      d = 2,998 10⁷ m

in the vacuum or air

At rest, a car’s horn sounds the note A (440 Hz). The horn is sounded while the car is moving down the street. A bicyclist movin
coldgirl [10]

Answer:

(a): The cyclist is behind the car.

(b): The speed of the car are Vf= 31.97 m/s.

Explanation:

f= 440 Hz

f'= 415 Hz

Vo= 1/3 Vf

Vf= ?

V= 343.2 m/s

f'= f* ( (V-(-Vo) / (V-(-Vf) )

clearing Vf :

Vf= 31.97 m/s

Vo= 10.65 m/s

A 5.7 kg particle starts from rest at x = 0 and moves under the influence of a single force Fx = 4.5 + 13.7 x − 1.5 x 2 , where
const2013 [10]

Answer:

The work done by the force on the particle is 29.85 J.

Explanation:

The work is given by:  

W = ^{x_{2}}_{x_{1}}\int F_{x} dx

Where:

x₁: is the lower limit = 0 m    

x₂: is the upper limit = 1.9 m

Fₓ: is the force in the horizontal direction =  (4.5 + 13.7x - 1.5x²)N

W = ^{1.9}_{0}\int (4.5 + 13.7x - 1.5x^{2}) dx  

W = 4.5x|^{1.9}_{0} + \frac{13.7}{2}x^{2}|^{1.9}_{0} - \frac{1.5}{3}x^{3}|^{1.9}_{0}  

W = 4.5N(1.9 m) + \frac{13.7N}{2}(1.9 m)^{2} - \frac{1.5N}{3}(1.9 m)^{3}    

W = 4.5N(1.9 m) + \frac{13.7N}{2}(1.9 m)^{2} - \frac{1.5N}{3}(1.9 m)^{3}      

W = 29.85 J

Therefore, the work done by the force on the particle is 29.85 J.

I hope it helps you!
