If one parent is a carrier of the cystic

1 answer:

7 0

An individual must inherit two non-functioning CF genes – one from each parent – to have CF. If both parents are carriers there is a 1 in 4 (25 percent) chance that both will pass on the non-functioning gene, which would result in a pregnancy affected with cystic fibrosis.

Most organisms in the fossil record no longer live on Earth. What does this

forsale [732]

Answer:

Explanation:

The fossil record

This supports Darwin's theory of evolution, which states that simple life forms gradually evolved into more complex ones. Evidence for early forms of life comes from fossils. By studying fossils, scientists can learn how much (or how little) organisms have changed as life developed on Earth.

If a car is traveling 100 km/h west and comes to a stop in 3 min, what is the car's acceleration?

Nataly [62]

Answer:

0.15 m/s² east

Explanation:

We can use following kinematic equation for Uniformly-Accelerated Motion to solve this problem:

Where v is the final velocity, v₀ is the initial velocity, a is the acceleration and t is the time interval.

The data of the problem is:

v₀ = - 100km/h (remember to have a frame of reference, I decided traveling west will be towards the negative values and traveling east will be positive).
v = 0 km/h (the car comes to a full stop)
t = 3 min

Replacing the data in the formula:

0 km/h = -100 km/h + a × 3 min

It's very important to use the same units when solving problems. I will convert kilometer to meters and hour or minutes to seconds, because the answer choices are given in m/s².

0 km/h = 0 m/s

$\frac{100 \ km}{\ \ h} * \frac{1000\ m}{1\ km} * \frac{1\ \ h}{3600\ s} = \frac{27.78\ m}{\ \ \ \ s}$
$3 min * \frac{60\ s}{1\ m} = 180 s$

Then:

$0 m/s = -27.78 \ m/s + a * 180 s\\+27.78 m/s = a * 180 s\\$

$\frac{+27.78 \ m/s}{180\ s} = a\\\\+ 0.15 m/s^2 = a$

And considering our frame of reference, a positive sign indicates that the acceleration is east-bound.
