Answer:
0.25 m
Explanation:
We can solve the problem by using the lens equation:
where
f is the focal length
p is the distance of the object from the lens
q is the distance of the image from the lens
In this problem, we have
f = +20 cm=+0.20 m (the focal length is positive for a converging lens)
q = +1.0 m (the image distance is positive for a real image)
Solving the equation for p, we find
Here is the solution to your problem
<span> resistivity Ag 15.9e-9 Ω-m
resistivity Fe 100e-9 Ω-m
temperature coefficient of resistivity
α = 0.0038/ºC Ag
R = R₀(1 + α∆T)
4*100 = 15.9(1 + (0.0038)∆T)
400/15.9 = 25 = 1 + (0.0038)∆T
(0.0038)∆T = 24
∆T = 6357ºC
add 25º to get 6382ºC </span>

Shale, sandstone, and limestone are the most commoc types of sedimentary rocks. They are formed by the most common mineral that is found on or near the surface of the Earth
Answer:
If there is a system of magnets being held in place, there is potential energy. When you let go the potential energy makes to kinetic energy and the magnets move.
