The average velocity is 20 km/h west
Explanation:
The velocity of an object is given by:
where
d is the displacement
t is the time elapsed
The displacement of an object is a vector connecting the initial position and the final position of motion.
In this problem, the car moved
40 km East
80 km West
Therefore, the displacement is given by (taking West as positive direction)
West
The time elapsed is
t = 2 h
Therefore, the average velocity is
in the West direction.

Answer:
since small stone has less mass so the gravitational pull of the earth is lesser in case of this but this is not for the bigger stone as the gravitational pull of the earth is greater...
PLEASE MARK BRAINLIEST!!!!!
Answer:
i/f = i/o + i/i f = focal, o = object, i = image
1 / i = 1 / f - 1 / o = (o - f) / o f
i = o * f / ( o - f) image distance
i = 12.5 * 22 / (12.5 - 22) = -28.9 cm
Image is real
Image is 28.9 cm to left of lens
M = - i / o = = 28.9 / 12.5 = 2.3 magnification (convex lens)
I guess the correct answer is the first one.
In RLC circuit the frequency of the circuit is also known as resonance frequency of the circuit
It is calculated by
now for the maximum value of the capacitance we will use minimum frequency as they depends inversely on each other
Now for minimum value of the capacitance
So above is the values of maximum and minimum capacitance
