Different: The weak nuclear force is responsible for radioactive decay within an atom of a substance, while the electromagnetic force causes electrostatic force between charged particles.
Different: The weak force has a very small range of effectiveness (where the force can be felt) while the electromagnetic force has an infinite range.
Same: Both forces act within an nucleus, or on a nuclear level.
Same: The weak nuclear force is mediated by charged particles called bosons, and the electrostatic force is only present within charged objects
The last one may be a bit of a stretch but I hope this helped a bit!
Answer:
False. Exercise should be around or at least one hour per day.
Answer:
Explanation:
F = Shearing force = 420 N
= Initial length = 2.6 cm
d = Diameter = 3.6 cm
r = Radius =
E = Young's modulus =
A = Area =
Change in length is given by
The shear deformation of the vertebra is
Using formula:
I=(1/2)*M*(R^2+r^2)
<span>I=0.5*0.715kg*[(12.7cm)^2+(10.7cm)^2] </span>
<span>I=98.6 kg*cm^2</span>
The answer of speed is 4.5m/s
