An atom is a smallest particle of an element.
Explanation:
It's particles are proton , electron and neutron.
Answer:
Specific gravity is 0.56
Explanation:
We know that
mass of water displaced by the wood is, m1( apparent mass when wood in air and lead is submerged in water) - m2(the apparent mass when wood and lead both are submerged in water)
= 0.0765 - 0.0452 = 0.0313 Kg
So the specific gravity of the wood is, = mass of wood / mass of water displaced by the wood
= 0.0175/0.0313
=0.56
<h2>
Spring constant is 6.73 N/m</h2>
Explanation:
For a spring mass system we have
Mass x Acceleration due to gravity = Spring constant x Elongation
mg = kl
Mass, m= 0.454 kg
Acceleration due to gravity, g = 9.81 m/s²
Spring constant,k = ?
Elongation, l = 0.662 m
Substituting
0.454 x 9.81 = k x 0.662
k = 6.73 N/m
Spring constant is 6.73 N/m
Heat is transferred to the driver's hands by conduction. The direct contact between the steering wheel and the driver's hands allows heat from molecules on the surface of the steering wheel to transfer to the molecules on the surface of the driver's hands. This is in contrast to convection (which requires a fluid in between the two surfaces that transfers heat).
