Answer:

The correct answer is option B.

Explanation:

Kinetic energy is the energy of the an object due to its motion.The kinetic energy of an object in motion is given as:

$K.E=\frac{1}{2}mv^2$

As we can see that kinetic energy is directly proportional mass and velocity of an object.

K.E ∝ m
K.E ∝ v

Momentum is the quantity of the motion possessed by the motion in object .

Momentum of the body = P

$P = m\times v$

As we can see that momentum is directly proportional mass and velocity of an object.

P ∝ m
P ∝ v

where :

m = mass of an object

v = velocity of an object

At the equator, the radius of the Earth is approximately 6370 km. A plane flies at a very low altitude at a constant speed of v

Anna007 [38]

To solve this problem we will apply the concepts related to the kinematic equations of linear motion. For this purpose we will define the speed as the distance traveled in a given period of time. Here the distance is equivalent to the orbit traveled around the earth, that is, a circle. Approaching the height of the aircraft with the radius of the earth, we will have the following data,

$R= 6370*10^3 m$

$v = 219m/s$

$a = 17m/s^2$

The circumference of the earth would be

$\phi = 2\pi R$

Velocity is defined as,

$v = \frac{x}{t}$

$t = \frac{x}{v}$

Here $x = \phi$ , then

$t = \frac{\phi}{v} = \frac{2\pi (6370*10^3)}{219}$

$t = 1.82*10^5s$

Therefore will take $1.82*10^5$ s or 506 hours, 19 minutes, 17 seconds

Answer:

Yellow, green, polka dot and white jerseys

Explanation:

Tour de France is the biggest bicycle race in the world held at France over a period of 23 days. At the end of each day of racing they give to the certain riders FOUR different colored jerseys:

The yellow jersey is given to the overall winner at each stage, this shows the rider who was the best in the previous stage.
The green jersey is given to the best sprinter of each stage,
The polka dot jersey is given to the rider who first reach the crest of designated hills and mountains at each stage.
The white jersey is given to the fastest rider at each stage under 25 years at the beginning of the racing year.

At the end of the competition, the total points are counted and the different jerseys are given to the overall winners.
