Answer:
d=13.81 mm
Explanation:
Given that
P = 15 KN ,L = 50 m
E= 200 GPa
ΔL = 25 mm
σ = 150 MPa
Lets take d=Diameter
There are we have two criteria to find out the diameter of the wire
Case I :
According to Stress ,σ = 150 MPa
P = σ A
By putting the values
d= 11.28 mm
Case II:
According to elongation ,ΔL = 25 mm
d=13.81 mm
Therefore the answer will be 13.81 mm .Because it satisfy both the conditions.
Answer:
The Wednesday test launch stored more potential energy, and launched the spacecraft at a faster speed because the stronger magnetic field closer to the magnet resulted in a greater increase in potential energy.
Explanation:
Answer:
<u>real and upside down </u>
Explanation:
Lens of a camera gathers light and focuses it on the light detector or film strip. <u>A real and inverted (upside -down) image is formed. </u>This image is then stored and processed and inverted. Thereafter we see an upright image. A chemical reaction on the film strip stores the image. In a digital lens, a light detector such as CCD stores the image.
