<span>What allows an arch bridge to span greater distances than a beam bridge, or a suspension bridge to stretch over a distance seven times that of an arch bridge? The answer lies in how each bridge type deals with the important forces of compression and tension.</span>
Consist of 8 to 10 reps to be most effective
Weight tending to shear the pin is
W = 24.0 N
The shear area of the pin is
A = (π/4)*(2.0 x 10⁻³ m)² = 3.1416 x 10⁻⁶ m².
The shear stress is
τ = (24.0 N)/(3.1416 x 10⁻⁶ m²)
= 7.64 x 10⁶ Pa
= 7.64 MPa
Answer: 7.64 Mpa
An infant galaxy that is studied through the use of radio waves is called QUASAR.
Quasar are astronomical object, which have very high luminosity and they are found in the centers of some galaxies. Scientists believed that quasar are centers of distant galaxies. Radio waves is used to study quasar because they emit a huge amount of radio waves.
Answer:
The electric field between the plates is 120 V/m.
(c) is correct option.
Explanation:
Given that,
Potential difference = 12 volt
Distance = 10 cm = 0.1 m
We need to calculate the electric field between the plates
Using formula of electric field
Where, V = potential difference
d = distance between the plates
Put the formula
Hence, The electric field between the plates is 120 V/m.
