Answer:
The correct answer is 50%.
Explanation:
In the given question, the table says that fruit color is determined by the incomplete dominance of allele R and R'. In the case of RR genotype the fruit color will be red and R'R' the food color will be yellow but in the heterozygous condition the color would be orange, so the cross between RR' and R'R' would be as follow:
Punnett square:
R R'
R' RR' R'R'
R' RR' R'R'
It is found by the given cross that the cross between RR' and R'R' would form two orange fruit plants out of four which is 50%
Force required = F = ?
mass of the car = m = 1200 kg
initial velocity of the car = Vi = 10 m/sec
final velocity of the car = 0
time required to stop the car = t = 20 sec
Using Newton`s 2nd law of motion;
F = ma ………………………(1)
as a = Vf - Vi / t , put this value in equation (1)
F = m ( Vf - Vi /t ) ………………(2)
F = 1200 ( 0 - 10 /20) = - 600 N
here Negative sign shows that external force is acting in opposite direction of the motion to bring it to rest.
we can also calculate this force by using the relation
Rate of change of momentum = net force acting on the object …………(3)
m Vf - m Vi / t = net force acting on the object
m (Vf - Vi / t) = F
1200 ( 0 - 10 /20) = - 600 N = F
so, net force acting on the object =F = - 600 N
