Answer:
A linear, positive relationship
Explanation:
The graph is a line, so it is linear and the slope is positive, so it is positive...
Newton realized that the reason the planets orbit the Sun is related to why objects fall to Earth when we drop them. The Sun's gravity pulls on the planets, just as we now understand Earth's gravity pulls down anything that isn't held up by some other force
Answer:
Option (a)
Explanation:
We will discard options that don't fit the situation:
Option b: <em>Incorrect </em>since if the driver "hits the gas" then velocity is augmenting and it's not constant.
Option c and d: <em>Incorrect </em>since the situation doesn't give us any information that could be related directly to the terrain or movement direction.
Option a: Correct. At <em>stage 1</em> we can assume the driver was going at constant speed which means acceleration is constantly zero. At <em>stage 2 </em>we can assume the driver augmented speed linearly, this is, with constant positive acceleration. At <em>stage 3 </em>we can assume the driver slowed the speed linearly, with constant negative acceleration.
Answer:
The current in the second wire is 8.33 A and the two currents are flowing in the opposite directions
Explanation:
Given that,
The separation between two long parallel wires, d = 2.5 cm
The force per unit length that each wire exerts on the other is, 
The current in one wire, 
(a) The force per unit length of the wire is given by :
On putting all the values we get :
So, the current in the second wire is 8.33 A.
(b) It is given that, both the wires repel each other, so the current in other wire is flowing in the opposite direction of the current in the first wire.
Hence, this is the required solution.
