Answer:

2500miles

Explanation:

Given parameters:

Time of travel  = 5hrs

Average speed  = 500miles/hr

Unknown:

Distance between the two cities  = ?

Solution:

To solve this problem, we must understand that speed is the distance covered with time.

  So;

      Distance  = speed x time

Distance  = 500 x 5 = 2500miles

A box with a mass of 0.6-kg falls from a very tall building. While free-falling it is subjected to a frictional drag force given
rjkz [21]

Answer:

1.03m/s

Explanation:

According to the question

Fdrag = bv²

now Fdrag = weight of the box

that is Fdrag = mg

where m = mass of the box, 0.6 Kg

and g = acceleration due to gravity

thus,

Fdrag = bv²   becomes

mg = bv²

making v the subject of formula

v = \sqrt{\frac{mg}{b} }

v = \sqrt{\frac{0.6 * 9.8}{5.5} }

v = 1.03m/s

What is the frequency of light when the energy for a mole of photons is 1. 55 × 1013 j?.
ValentinkaMS [17]

The frequency of light is 3.88 x 10^22Hz.

What is electromagnetic radiation?

The electromagnetic spectrum is the area where the electromagnetic radiation that we see as light, or visible light, is found. Visible light usually has wavelengths between 400 and 700 nanometers (nm) or frequencies between 750 and 420 terahertz, which are between the longer wavelengths of infrared and ultraviolet (with shorter wavelengths).

E = 1.55 x10^13 J/ mol

E = hv

v = 1.55 x 10^13/1mol  x 1mol/6.023 x )/6.626 x

velocity = 3.88x10^22 s-1

since 1 Hz = 1/ s = 1

velocity =3.88x 10^22 Hz
