Answer:
Both technicians are right, to be able to make a threaded joint you need to use the external thread on one part of the rod using the tap and die set, and on the other side of the rod you need to have an internal thread using the thread repair insert kit
Constant = straight line
“Travels at constant negative acc.”
Which is negative slope
Solution: B. Straight line w/ neg. slope
P=E/t
E=67,500J
t=45s
P=?
P=67,500/0.45
= 150000W
True it help support reglions
Measure the distance between an object and the lens after using the lens to focus on it. The focal length is at this range.
<h3>How simple is it to determine a lens's focal length?</h3>
Focus a far-off object on a wall by adjusting the convex lens up and down along the scale. The picture that forms on the wall is very close to the lens' focus, and the metre scale can be used to read how far away the lens is from the image. This approximates the lens's focal length.
<h3>How do you calculate a concave lens's focal length?</h3>
The formula f=uv/u-v is used to get the focal length of the concave lens using the values of u and v.
