Dominant genes and recessive genes are both given to a parents offspring. However, not both can be expressed causing the difference of dominant and recessive. Dominant genes are more likely to be expressed and recessive genes are more likely to be repressed.
It will land in your lap because there's different frames of motion relative to yourself. For example, if you're running at a speed of 6 mph, it doesn't mean you'll run as fast as the Earth spins. Also, since you're on the interior of the plane, any kind of wind or weather on the outside will not affect the coin. A law to back up this claim is Einsteins Special Law of Relativity.
Answer:
law of conservation of energy states that the total energy of an isolated system remains constant; it is said to be conserved over time.
If three atoms of helium fuse to form carbon than 0.009 u of mass is converted into energy
Given: m(He) = 4.003 u
and m(C) = 12.000 u
Mass of 3 alpha particles =3×4.003 u
=12.009 u.
Mass of 1 carbon atom=12.000 u
Mass Defect =△m=12.009−12.000=0.009 u
Energy released =0.009×931.5=8.3835 MeV.
So, 0.009 u of mass is converted into 8.38 Mev energy.

#SPJ4
mass of the ball m = 0.63 kg
initial height h = 1.8 m
final height h ' = 3.03 m
initial speed v = 7.09 m / s
final speed v ' = 4.21 m / s
Let the work done on the ball by air resistance W = ?
we know from law of conservation of energy ,
total energy at height h + work done by air = total energy at height h '
mgh + ( 1/ 2) mv^ 2 + W = mgh ' + ( 1/ 2) mv'^ 2
0.630*9.8*1.8 + 0.63*7.09^2 + W = mgh ' + ( 1/ 2) mv'^ 2
From there you can find W
if there is negative sign indicates it work opposite direction to motion
