At t = 0 a truck starts from rest at x = 0 and speeds up in the positive x-direction on..., the time the truck passes the car and the coordinate the truck passes the car is mathematically given as

  • t = \frac{2v_{C}}{a_{T} + a_{C}}
  • d_{T} = v_{T}t + \frac{a_{T}t^{2}}{2}
<h3>What time does the truck pass the car and coordinate does the truck pass the car?</h3>

Generally, the equation for Distance traveled is mathematically given as

By Truck

d_{T} = v_{T}t + \frac{a_{T}t^{2}}{2}

By Car

d_{C} = v_{C}t - \frac{a_{C}t^{2}}{2}

In conclusion, when the conditions the truck passes the car

d_{T} = d_{C}

Therefore

v_{t} + \frac{a_{t}t}{2} = v_{C} - \frac{a_{C}t}{2}

\frac{a_{T}t}{2} = v_{C} - \frac{a_{C}t}{2}

Therefore

t = \frac{2v_{C}}{a_{T} + a_{C}}

differentiation of  T

d_{T} = v_{T}t + \frac{a_{T}t^{2}}{2}

Which uses the refractive properties of light to separate it into its different wavelengths?
miss Akunina [59]

A). No.  A mirror doesn't separate light into its different wavelengths.

B). No.  Light doesn't separate into its different wavelengths when it
goes, say, from glass into water.

C). No.  When light goes through your glasses, it doesn't separate
into its different wavelengths.

D). Yes !  When sunlight shines into droplets of water in the atmosphere,
it comes out separated into its different wavelengths.  When we see that
happening in the air in front of us, we call it a "rainbow".

When you go out into the sun, the UV light can give you a tan. UV light has a frequency of 7.89 x 1014 Hz. What is the wavelengt
Olin [163]

Answer:

Explanation:

Formula and givens

  • λ = c / f
  • λ is the wavelength
  • c = the speed of light
  • f = the frequency
  • c = 3*10^8
  • f = 7.89 * 10^14

λ = ?

Solution

λ = 3*10^8 / 7.89*10^14

λ = 3*10^8/7.89*10^14

λ = 2.36 * 10^7

λ = 236 nanometers. What you use as your solution depends on what what you have been taught.

A person is standing on top of a cliff and falls down. If he takes 3.7 s to hit the ground, how high up is the cliff?
Maksim231197 [3]

Answer:

h = 67.081 m

Explanation:

Given that,

The time taken by a person to fall down is, t = 2.2 s

The height of the cliff from the ground, h = ?

The distance that the person will fall through the time is given by the formula

                               S = 1/2 gt²  m

Where,        

                             g - acceleration due to gravity

Substituting the values in the above equation

                              S = 1/2 x 9.8 m/s² x (3.7 s)²

                                 = 67.081  m

Therefore, the height of the cliff from the ground is, h = 67.081  m
