Answer:

<em>The green car had the greatest momentum</em>

Explanation:

<u>Momentum</u>

Momentum can be defined as "mass in motion" and is calculated as the product of the mass of the object by its velocity.

Being v the magnitude of the velocity and m the mass of the object, the momentum is calculated with:

p = mv

The green car had a mass of m1=1200 kg and crossed the finish line at v1=53 m/s. Hence, its momentum was:

p1 = 1200 Kg * 53 m/s = 63600 Kg.m/s

The red car had a mass of m2=1100 kg and crossed the finish line at v2=55 m/s. Hence, its momentum was:

p2 = 1100 Kg * 55 m/s = 60500 Kg.m/s

Since p1 > p2, then the green car had the greatest momentum

Which has a total mass of 1612 kg. If she accelerates from rest to a speed of 12.87 m/s in 3.47 s, what is the minimum power req
blondinia [14]

Answer:

76969.29 W

Explanation:

Applying,

P = F×v............. Equation 1

Where P = Power, F = force, v = velocity

But,

F = ma.......... Equation 2

Where m = mass, a = acceleration

Also,

a = (v-u)/t......... Equation 3

Given: u = 0 m/s ( from rest), v = 12.87 m/s, t = 3.47 s

Substitute these values into equation 3

a = (12.87-0)/3.47

a = 3.71 m/s²

Also Given: m = 1612 kg

Substitute into equation 2

F = 1612(3.71)

F = 5980.52 N.

Finally,

Substitute into equation 1

P = 5980.52×12.87

P = 76969.29 W

The photons of different light waves:
LuckyWell [14K]

Answer: contain different amounts of energy

Explanation:

The energy E of a photon is given by:

E=h\nu

Where:

h=6.626(10)^{-34}\frac{m^{2}kg}{s} is the Planck constant

\nu is the frequency of the light which is inversely related to the wavelength.

Now, if we have photons of different light waves, this means we have photons with different frequencies.

As the energy of the photon depends on its frequency:

Photons of different light waves <u>contain different amounts of energy.</u>
