Electrons make a negative charge because electrons are negative. But when atoms lose electrons they make a positive charge.
Hope this helped! :)
Ima say oscillating wave since its not a wave category its somthing a wave does..............<span>In physics, a </span>wave<span> is an </span>oscillation<span> accompanied by a transfer of energy </span>
Answer:
= 154 cm
= 216.6 cm
The image is real
Explanation:
= height of the object = 3.20 cm
= height of the image = 4.50 cm
f = focal length of the converging lens = 90 cm
= object distance from the lens = ?
= image distance from the lens = ?
using the equation for magnification
= 1.40625 eq-1
using the lens equation
using eq-1
= 154 cm
Using eq-1
= 1.40625
= 1.40625 (154)
= 216.6 cm
The image is real
Answer:
The distance travelled is 151.22m and it took 0.97s
Explanation:
Well, this is an ARM problem, so we will need the following formulas
where is the initial position (we can assume is zero), is the initial speed of 104 m/s, is the initial time (we also assume is zero), a is the acceleration of 107 m/s2, v is speed, x is position and t is time.
Now that we have the formulas, we know that when the electron stops it has no speed. Then we calculate how much time it takes to stop.
Finally, we calculate the distance travelled in this time
