Using Ohm's Law, R = V/I;
R = (1.5V)/(0.5A) = 3.0Ω
Answer: D. 12 m/s
Explanation:
Use the formula of then just solve by inserting the numbers.
You use the first mountain height(5) and the second mountain height(12) and insert to the equation.
Sole and you'll be left with 12.
Add the labeling "m/s"
and youre done!
tehe ur welcome vanessaaa
Answer:
The work done by the electric force is =
The potential of the starting point with respect to the end point is
The magnitude of E
Explanation:
Looking at this we can see that the work done by the electric force is equal to the kinetic energy this is because on the electric field is uniform and that the work done resulted in motion.
Mathematically
Where is the potential difference
q is the charge whose value i given as =
W is the workdone whose value is obtained as =
Substituting
Mathematically
Where E is the electric field strength
d is the distanced moved and it is given as 6.00 cm = 0.06 m
Making E the subject of the formula
When an object moves its length contracts in the direction of motion. The faster it moves the shorter it gets in the direction of motion.
The object in this question moves and then stops moving. So it's length first contracts and then expands to its original length when the motion stops.
The speed doesn't have to be anywhere near the speed of light. When the object moves its length contracts no matter how fast or slow it's moving.
