RNA has Uracil instead of Thymine. All the other three bases also occurs in RNA, adenine, guanine and cytosine. Therefore a ATA DNA codon will be transcript to UAU by RNA. Both Thymine and Uracil have the same role in however have minor chemical differences.
Answer:
D. Which cell organelles carry out the process of photosyinthesis and cellular respiration?
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
Um there is no picture. I would love to help you though
