Answer:
Muscular Dystrophy : 50%
Breast cancer: 50%
Explanation:
Muscular Dystrophy (linked to X):
1/2 (mother) x 2/2 (father) = 2/4 (50%) chance of having an affected child with MD
Breast cancer (autosomal dominant disorder):
1/2 (mother) + 0 (father) = 1/2 = 50% chance of having an affected child with breast cancer
Answer:
10 m/s/s or m/s²
Explanation:
Acceleration can be calculated by using the formula;
a = v - u/t
Where;
a = acceleration (m/s²)
v = final velocity (m/s)
u = initial velocity (m/s)
t = time (s)
In other terms, acceleration (a) can be represented as ∆V/t.
According to this question, a ball accelerates from 10 m/s (u) to 30 m/s (v) in 2 seconds. Hence, the acceleration of the ball is as follows:
a = 30 - 10/2
a = 20/2
a = 10m/s².
Fractures are common injury during childhood with 8 to 12 percent. For toddlers like of a 3 years old femur fractures usually comes from a low energy fall. The doctor after an x-ray puts the affected leg in a Spica cast. In order to obtain history of what happened prior and during the injury, it would be better to ask the parents first especially if they are present during the incident. Afterwards, if they are not present those who witnessed the incident can be asked like if a teacher was present she can attest to what really happened.
