Answer:
the two skaters will meet at a distance of 9.75 m from the initial position of 35 kg skater
Explanation:
Since there is no external force on the system of two skaters
So the two skaters will meet at the position of their center of mass
so let the position of 35 kg skater is origin
then the position of other skater is 15 m
now by the formula of center of mass we have
so the two skaters will meet at a distance of 9.75 m from the initial position of 35 kg skater
When light is passing from a denser medium to a lighter medium ( for example: from water to air)
<span> When the angle of refraction is greater than the critical angle( angle of incidence when the angle of refraction is perpendicular to the normal) of the denser medium.</span>
the answer is A. Their is less friction between the tire and the road at position A than at position B.
Answer:
Temperature is a measure of the average kinetic energy of the particles in matter. The Fahrenheit scale defines the freezing point of water as 32°F and the boiling point as 212°F.
