Answer:
True
Explanation:
Johannes Kepler was a German astronomer, mathematician and astrologer. He proposed a model of the solar system which remains in use, with some modifications. Moreover, he developed the laws of planetary motion which explain how the planets move around the sun. This work was not only significant on its own, but it also provided the foundations for Newton's theory of universal gravitation.
What is the value of the voltage? There must be one somewhere.
This might be too simple minded, but I'll give it a voltage of 10 Volts.
R = voltage / Current
R = 10 / 0.5
R = 20 volts.
Perhaps you could post a diagram if this is a Kirchhoff Law Question.
Answer:
6.25 m/s
Explanation:
Given parameters
Initial mark = 65
Final mark = 15
time taken = 8s
Unknown:
Velocity of the runner = ?
Solution:
Velocity is the displacement divided by time;
Velocity = 
Displacement = Initial mark - final mark = 65 - 15 = 50m
Now, insert the parameters and solve;
Velocity = 
= 6.25m/s
