Tobacco smoking is an unhealthy habit which can cause cancer due to the presence of more than 5000 chemicals, some of which are carcinogens (a chemical that causes cancer). It is the smoke itself, that carries carcinogens to the lungs and can eventually lead to the development of diseases such as lung cancer.
The motion of the light is a uniform motion with constant speed

, therefore we can use the basic relationship between speed, space and time:

(1)
where S is the distance covered and t is the time taken. The light takes t=1.3 s to travel from the moon to Earth, therefore by rearranging eq.(1) we can find the distance between the Moon and the Earth:
Answer:
<h2>Total thermal energy for all air molecules is 59.54 J</h2>
Explanation:
As we know that the ball comes to rest finally so here we can say that
initial total potential energy of the ball is transferred to the air molecules
So here we have


So here we have

So all the gravitational potential energy of the ball will convert into thermal energy of air molecules which is equal to 59.54 J
0.33 . Equation is Force of friction equals normal force times coefficient of friction, so 6=18u. Divide 6 by 18
Answer:
<em>The ball travels up to 16.53 meters above the player's head</em>
Explanation:
<u>Vertical Launch Upwards</u>
In a vertical launch upwards, an object is launched vertically up from a height H without taking into consideration any kind of friction with the air.
If vo is the initial speed and g is the acceleration of gravity, the maximum height reached by the object is given by:

The initial speed of the soccer ball is vo=18 m/s. The initial height can be assumed to be zero because we are required to find the maximum height with respect to the player's head, where the vertical motion was initiated.
Calculate the maximum height:


The ball travels up to 16.53 meters above the player's head
