First identify the gametes. Use pink labels to identify the male and female gamete types and white labels to identify the gamete frequencies.
Then identify the F2 progeny. Use pink labels to identify the progeny geno types and white labels to identify the progeny <span>frequencies.</span>
Answer:
Option D - 0.2 s
Explanation:
We are given;
Initial velocity; u = 7 m/s
Height of table; h = 1.8m
Now,since we want to find the time the car spent in the air, we will simply use one of Newton's equation of motion.
Thus;
h = ut + ½gt²
Plugging in the relevant values, we have;
1.8 = 7t + ½(9.8)t²
4.9t² + 7t - 1.8 = 0
Using quadratic formula to find the roots of the equation gives us;
t = -1.65 or 0.22
We can't have negative t value, thus we will pick the positive one.
So, t = 0.22 s
This is approximately 0.2 s
Answer:
4.78 kg/m^2.
Explanation:
τ = Iα
Where,
τ = torque, around a defined axis (N∙m)
I = moment of inertia (kg∙m2)
α = angular acceleration
= 1.2 rad/s^2
τ = F * r
= 16.88 * 0.34
= 5.74 N.m
Therefore, I = 5.74/1.2
= 4.78 kg/m2
