P=m x v =60 x 7.0= 420
total momentum = 420 x 2,000,000,000=dnt have a calculator
thier effect would shake the earth and kill some organism because they jump up at the same time and they wil probably land the same time .

what is the wavelength of light (in nanometers) that has a frequency of 1.75 x 1013 hz? the speed of light is 3.00 x 108 m/s.
Leokris [45]

The light has a frequency of 1.75 x 10¹³ hz. The speed of light is 3.00 x 10⁸ m/s. The wavelength of light is (λ) = 1.714 x 10⁴ nm

<h3>What is wavelength?</h3>

When a wave that propagates in a medium it has different lengths. That length of the wave is called the wavelength. It can be measured in m, cm, nm etc.

<h3>How can we calculate the wavelength?</h3>

To calculate the wavelength we are using the formula,

λ=c/f

Here we are given,

c= The speed of light in zero space. = 3.00 x 10⁸ m/s.

f = The frequency of the light. = 1.75 x 10¹³ hz.

We have to calculate the wavelength of the light = λ m

Now we put the values in above equation we get,

λ=c/f

Or, λ=3.00 x 10⁸ / 1.75 x 10¹³

Or,  λ= 1.714 x 10⁻⁵ m

So we can easily say that,

The wavelength of light is (λ) =1.714 x 10⁻⁵ m = 1.714 x 10⁴ nm

When velocity is graphed with respect to time, what does the area under
Juliette [100K]

Answer:

the answer is D

Explanation:

Since the velocity of the object is the derivative of the position graph, the area under the line in the velocity vs. time graph is the displacement of the object.

A skier is traveling fast down a mountain slope. The table shows data
melisa1 [442]

Answer:

The pushing force and the skier's mass

(A) is correct option.

Explanation:

Given that,

Mass = 64 kg

Weight = 608 N

Velocity = 21 m/s

Forward force = 45 N

We need to calculate the reaction force of the snow pushing  on the skier

Using given data,

The reaction force of the snow pushing  on the skier is equal to the pushing force and the skier's mass.

Hence, The pushing force and the skier's mass

(A) is correct option.
