It is the instantaneous speed of the bike rider.

Explanation:

At the mile marker, the measured speed gives the instantaneous speed of the bike rider.

The instantaneous speed is speed measured at a precise or instance of time.

 Speed is the rate of change of distance with time. It is a scalar quantity that only shows magnitude with no reference to direction.

  Velocity is the displacement divided by time. It has both magnitude and directions.

Average speed is measured over a period of time as the distance increases from the starting point.

From this, we can see that 13.5mph is the instantaneous speed of the bike rider.

Suppose our apparatus will only allow us to distinguish the first order bright fringe from the central bright spot if they are s
ozzi

Answer:

λ = 8.716 mm

Explanation:

Given:

- d = 10 cm

- Q >= 5 degrees

Find:

- Find the shortest wavelength of light for which this apparatus is useful

Solution:

- The formula that relates the split difference and angle of separation between successive fringes is given by:

                                            d*sin(Q) = n*λ

Where,

λ: wavelength

d: split separation

Q: angle of separation between successive fringes

m: order number.

- Since this apparatus only shows the first order light so m =1

- the shortest possible wavelength corresponds to:

                                            d*sin(Q) = λ

                                            λ = 0.1*sin(5)

                                            λ = 8.716 mm

We know, length of segment wave is half the wavelength .

Let, wavelength of wave is \lambda.

So, length of segment will be \dfrac{\lambda}{2} .

Now, it is given that the string vibrates in four segments.

So,

L = 4\times \dfrac{\lambda}{2}\\\\L = 2\lambda\\\\\lambda = 1\ m

Speed can be given by :

speed = wavelength \times frequency\\\\speed = 1\times 120\  m/s\\\\speed = 120\ m/s

Therefore, the wave speed in the string is 120 m/s.

On Earth, a scale shows that you weigh 585 N. What would the scale read on the Moon (g = 1.60 m/s2)? N
Serggg [28]

Answer:

95.51 N

Explanation:

First, find the mass in kg:

Fg = 585 N

Fg = m*g

585 N = m*9.8 m/s^2

<u>m = 59.69 kg</u>

Then, to find your weight (Fg) on the moon, you use the same equation of

Fg(moon) = m*g, except this time g = 1.60 m/s^2

Fg(moon) = 59.69 kg * 1.60 m/s^2

Fg(moon) = 95.51 N

Hope this helps!! :)

What is force and measurement​
NeTakaya

Explanation:

In physics, force is a quantitative description of an interaction that causes a change in an object's motion. ... It is defined as Mass x Acceleration = Force. The SI unit of force is the newton (N); defined as the unit of force which would give to a mass of one kilogram an acceleration of 1 meter per second squared. hope this helps you discover the best answer
