Distance is the total length of an object's path. Displacement is the overall change in position, ie. how far an object is from its initial position.
The court is 30 m long, so a path going back and forth once is 60 m long. Going along this path 6 times totals 360 m.
The end point is the same as the starting point, so the displacement is 0 m.
<span>CH4 I assume you're doing a test or something but I'm not good at explaining things so hopefully it's multiple choice! </span>
Answer:
Part a)
Part b)
Explanation:
As we know that electric force on electric charge is given as
here we have
E = 153 N/C
now force is given as
Gravitational force on electric charge near surface of earth is given as
now the ratio of two forces is given as
Part b)
Now the ball is balanced by the electric force and the force of gravity on it
so here we have
here we have
Explanation:
Incident light makes an electron oscillate. The electrons emit light or absorb the light, collide with other electrons, thereby converting light energy to more internal energy. and convert it to heat.
Light wave of a given frequency is incident on a material with electrons having the same vibrational frequencies, then electrons absorb the energy of the light wave and transform it into vibrational motion.
Answer:
44.21053 m
279.69925 seconds
Explanation:
Time taken by the squirrel to reach the finish line
Time taken by the horse to cover 0.96 km
Time taken by the horse to cover 1.2 km
Let the distance that the squirrel is from the finish line when the horse resumes the race be x.
During this time the horse also reaches the finish line.
We deduce that
The time taken by the horse from one stop = Time taken by squirrel before x distance from finish line.
The squirrel is 44.21053 m from the finish line when the horse resumes the race.
Duration is given by
The duration is 279.69925 seconds
