Answer:
you are the one who gives meaning to your life, do what u want to do. try new things and just enjoy the good things that you alreadyknow u like. you shouldn't look at life as a competition or as a task that needs something to be done, just do whatever u want
Answer:
66.28 s
Explanation:
Step 1:
Acceleration,a=
Time,t=9.75 min=
1 min=60 s
Initial velocity,u=
We have to find the final velocity of train.
We know that

Substitute the values

Step 2:
Now, initial velocity,u=41.425m/s
Deceleration,a=
Because the train velocity decreases
Final velocity, v=0
Again, substitute the values in the above formula




Hence, the train takes 66.28 s to come to stop from velocity 41.425m/s.

6)
a 0.8 (if it is the one on the right of 6)
b 0.4 [A]
c 0.4 [A]
d depends on where you place it.
7)
a place it next to X, right or left

Answer:
106 single crossover events
Explanation:
Total number of offspring = 1250
<u>Determine the number of offspring that would be expected </u>
( Rf between the genes vg and Pr ) * ( Total number of progeny )
= 0.125 * 1250 ≈ 156 ( value for single and double crossovers )
next :
( value of the Rf of double crossovers ) * ( Total number of progeny )
= (0.322 * 0.125) = 0.04025 * 1250 = 50
Hence the number of offspring expected to obtain/represent a single crossover event between pr and vg
= 156 - 50 = 106
Answer:
810 kJ
Explanation:
Work done is equal to change in kinetic energy
W=∆KE
Change in kinetic energy is given by
∆KE=½m(v²-u²)
Where ∆KE is the change in kinetic energy, m is mass of the vehicle, v is final velocity while u is initial velocity.
Since the vehicle must come to rest, the final velocity is zero.
Substituting 1800 kg for m, 0 m/s for v and 30 m/s for u then
∆KE=½*1800(0²-30²)=-810, 000J
Converted into kJ
∆KE=-810 kJ
Therefore, work done is 810 kJ
