Kinetic energy = 1/2mv^2
=1/2(25)(1^2)
= 12.5J
Answer:
C
Explanation:
From the question we are told that a vector on the x and y plane face their negative axis
Generally in the x and y plane thr negative y axis is made to face down opposite the positive y axis
Whilst the negative x axis faces the left which is also alternate to the positive x axis
Generally A vector pointing towards the x and y negative axis fro the origin (0) will definitely be in the third quadrant
The resistance of a conductor is inversely proportional to the cross sectional area of the conductor.
<u>Explanation:</u>
The resistors are used to resist or block the flow of current in any circuit. As per Ohm's law, resistance is inversely proportional to the current flow or charge in the circuit. But the resistance of a conductor will depend on the length of the conductor and cross sectional area of the conductor along with specific resistance of the material with which the conductor is made.
Here, Rho is the specific resistance, L is the length of the conductor and A is the cross sectional area of the conductor.
As the resistance offered by the conductor will be directly proportional to the length of the conductor and inversely proportional to the cross sectional area of the conductor. So the resistance of a conductor is inversely proportional to the cross sectional area of the conductor.
Answer:
The average speed is 8.0 km/h
Explanation:
We use the data for the return journey to calculate the distance travelled using the constant velocity equation:
s = v t =6*4=24km
Note I didn't change any units so the answer comes out in kilometres.
Now use the distance and time taken to travel to Guam to find the average speed:
v=st=24/3=8.0km/h
