In the space below, explain why you agree or disagree with the first statement: Each person in a family has the same traits. There are no differences in traits between parents and offspring or among siblings.

Answers

Answer:

I disagree.

Explanation:

Yes, traits may be similar, but it all depends on the dominant and recessive alleles that are passed on. No one person can look alike. Even with twins, a widow's peak or close lobes can be different.

A rock falls off the edge of a cliff and strikes the ground after 3.8 s. What is the height of the cliff? Assume air resistance is negligible.

Answers

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.

Use the formula:
h = vo*t - (1/2)gt^2

Since the rock experiences freefall, initial velocity (vo) is zero:
h = -(1/2)gt^2

Substitute:
h = -(1/2)(-9.8)(3.8^2)
h = 70.756

You're conducting a physics experiment on another planet. You drop a rock from a height of 2.3 m and it hits the ground 1.1 seconds later. What is the acceleration due to gravity on this planet?A. 4.2 m/s2
B. 3.8 m/s2
C. 2.4 m/s2
D. 9.8 m/s2

Answers

Acceleration due to gravity on this planet will be 3.802 m / s^2

What are equations of motion?

Equation of motion are defined as equations that describe the behavior of a physical system in terms of its motion as a function of time

Using equation of motion

u=0

s= 2.3 m

t = 1.1 sec

to find = g (acceleration due to gravity on this planet)

s = u t + 1/2 (a ) (t ^(2))

s = 1/2 (g) (t^2)

2.3 = 1/2 (g) (1.1^2)

g = 2 * 2.3 /(1.1)^2

g = 4.6 /1.21= 3.802

correct answer is b) g = 3.802 m / s^2

Compute the resistance in ohms of a copper block 5.0 cm long and 0.10 cm2 in cross-sectional area. (ρ = 1.77 × 10-6 ohm-cm)

Answers

R=ρ l/a
l=5 cm
a=0.10 cm²
ρ=1.77×10∧-6 Ωcm
R=(1.77×10∧-6) ×5/0.10
=8.85 ×10∧-5 Ω

resistance is directly proportional to length and inversly proportional to area of cross section is given by above equation

The temperature scale which starts at absolute zero is the _____.Centigrade scale
Celsius scale
Fahrenheit scale
Kelvin scale

Answers

The temperature scale which starts at absolute zero is the Kelvin scale. The correct option in respect to the given question is the last option. William Thompson was the British scientist and inventor that invented the Kelvin scale. William Thompson was also popularly known as Lord Kelvin.His discovery of the Kelvin scale is considered one among the three best scales in use for measuring temperatures.Each measuring unit of this scale is never called a degree but a Kelvin. This specialized scale gives the option of measuring temperature in both centigrade and Fahrenheit.

the temperature that the scale starts at absolute zero is called the Kelvin scale
