An image that a concave mirror can make is that it <span>can form a real image that is projected out in front of the mirror. </span>A concave mirror<span> is a mirror that is curved inward in the middle. Using the mirror equation, you can deal with concave mirrors. It's like you're looking into a cave when try to look in a concave mirror.</span>
Answer:
Explanation:
V1 = 31 V
V2 = 168 V
charge on proton, q = e
(a)
The change in potential energy is given by
ΔU = q ( V2 - V1)
ΔU = e (v2 - V1)
(b)
ΔU = e (168 - 31)
ΔU = 137 eV
(c)
Work done = change in potential energy
W = 137 eV
W = 137 x 1.6 x 10^-19
W = 2.19 x 10^-17 J
Answer:
666.6 seconds
Explanation:
if he runs at 3m/sec he will achieve the goal of 2000m in 666.6 seconds. just divide - 3/2000.
note we have changed 2km to 2000metres
1. What is the skydiver's acceleration?
Initially, like any falling object, a skydiver's downward acceleration is 9.8 meters/seconds^2, or about 28-35 feet per second squared. This acceleration reduces over a few seconds and approaches zero as the skydiver reaches terminal velocity.
Answer:
I think D. maybe C
Explanation:
newtons is force of gravity and grams can be weight or mass in the metric system
