Answer:
Force F = 1535.86 N
the force necessary for his wife to hold onto their child during the collision is 1535.86 N
Explanation:
Given;
Mass of toddler m = 13 kg
Velocity v = 37 mi/h = 37 × 0.44704 m/s = 16.54 m/s
Impulse time t = 0.14 seconds
Using the impulse momentum equation,
Impulse = change in momentum
Ft = m(∆v)
Force F = m(∆v)/t
∆v = 16.54 m/s
F = 13×16.54/0.14
Force F = 1535.86 N
Answer: The correct answer for the blank is- Replication.
DNA replication is a biological process in which two identical replica of DNA are produced from single original DNA molecule through an enzyme called as DNA polymerase.
The two strands of double helical DNA are first separated ( with the help of helicase enzyme) so that the template DNA strands are exposed. In other words, the two strands are broken apart and attract new nucleotide bases to synthesize a new and complete strand of DNA.
This is done by DNA polymerase according to Watson and Crick base pairing ( A pairs to T, G pairs to C)
Answer:
15.8640053791 s
392.780107582 m
29.5184032275 m/s
Explanation:
0 denotes initial
x denotes displacement
c denotes car
t denotes truck
r denotes rear
For the car
The displacement of the truck will be
From the above two equations we get
The time taken is 15.8640053791 s
The distance the car travels is 392.780107582 m
The velocity of the car is 29.5184032275 m/s
