Khalil is driving laps at a racetrack. The track is circular and has a radius of 25 m. After

The difference between the distance and the displacement is the speed is a scalar while displacement is a vector.

<h3>What is the distance an the displacement?</h3>

The distance is the difference between two points while the displacement is the difference between two points in a specified direction. Given that speed is a scalar and the displacement is a vector. It follows that we must take the displacement when obtaining the displacement.

Thus, the distance that is covered after one lap is  the circumference of the circle = 2πr = 2 * 3.142 * 25 = 31 m Then for 2 laps = 62 m

The displacement is obtained when we take the direction into consideration. Owing to the fact that the runner returns to the starting point each time, the displacement is zero.

Light is shining perpendicularly on the surface of the earth with an intensity of 680 W/m^2. Assuming that all the photons in th
andrew11 [14]

Answer:

3.066×10^21  photons/(s.m^2)

Explanation:

The power per area is:

Power/A = (# of photons /t /A)×(energy / photon)

E/photons = h×c/(λ)

photons /t /A = (Power/A)×λ /(h×c)  

photons /t /A = (P/A)×λ/(hc)

photons /t /A = (680)×(678×10^-9)/(6.63×10^-34)×(3×10^-8)

                      = 3.066×10^21

Therefore, the number of photons per second per square meter 3.066×10^21  photons/(s.m^2).

The key to making a concise mathematical definition of escape velocity is to consider the energy. If an object is launched at it
Keith_Richards [23]

Answer:

Zero

Explanation:

Total energy of the EARTH  is the sum total of the all the kinetic and the gravitation potential energy of the earth.

Which can be written as

E_{total} = KE+U

= \frac{1}{2}mv^2+ \frac{GMm}{R}

At very large distances the kinetic as well as the gravitational potential energies become zero.

therefore, E_total= 0
