Answer:
<em> It takes 186.67 second for the light to travel from Mars to earth.</em>
Explanation:
Light: Light is a visible form of energy which is radiated outward from a source. Light travels in a straight line, and this phenomenon is called rectilinear propagation of light.
S = d/t .......................... Equation 1
making t the subject of the equation
t = d/S ......................... Equation 2
Where S = speed of light, d = distance between the earth and Mars, t = time
<em>Given: d = 56000000 km, S = 300000 km per seconds.</em>
<em>Substituting these values into equation 2</em>
<em>t = 56000000/300000</em>
<em>t = 186.67 seconds.</em>
<em>Thus it takes 186.67 second for the light to travel from Mars to earth.</em>
Answer:
<h3>600kg</h3>
Explanation:
<h3> <u>MOMENTUM</u></h3>
<u>This</u><u> </u><u>is</u><u> </u><u>a</u><u> </u><u>product</u><u> </u><u>of</u><u> </u><u>a</u><u> </u><u>mass</u><u> </u><u>and</u><u> </u><u>velocity</u><u> </u><u>of</u><u> </u><u>a</u><u> </u><u>moving</u><u> </u><u>or</u><u> </u><u>a</u><u> </u><u> </u><u>rest</u><u> </u><u>body</u><u>.</u>
<u>it</u><u> </u><u>is</u><u> </u><u>expressed</u><u> </u><u>as</u><u> </u><u>P(momentum)=M(mass)</u><u> </u><u>×</u><u> </u><u>V(velocity)</u>
<u>Its</u><u> </u><u>SI</u><u> </u><u>unit</u><u> </u><u>is</u><u> </u><u>kgm</u><u>/</u><u>s</u>
<u>From our question</u>.
Given
Momentum=3600kgm/s
Velocity=6m/s
RTF=Mass
<u>Solution</u>
P=M×V
M=P/V
= <u>3600kgm/s </u>
<u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u> 6m/s
<h3> = <u>600kg</u></h3>
