∆y is change in y (velocity) and ∆x is change in x (time)
So from the graph we see that ∆y is zero and ∆x is also zero (value is changing with same ratio)
∆y/∆x= slope = 0
The allele for red skin is dominant R
The allele for yellow skin is recessive r
The genotype Rr is heterozygous, resulting in phenotype: red skin tomato
The genotype RR is dominant homozygous, resulting in phenotype: red skin tomato
The genotype rr is recessive homozygous, resulting in phenotype: yellow skin tomato

Answer:
The change in the car's momentum is equal to -8910 kgm/s.
Explanation:
Given that,
The mass of a car, m = 990 kg
Initial speed, u = 22 m/s
Final momentum, v = 13 m/s
We need to find the change in the car's momentum. The change in momentum of the car is given by :
So, the required change in the car's momentum is equal to -8910 kgm/s.
Answer:
<em>The lighten travels 0.853 miles.</em>
Explanation:
Sound: Sound is a form of wave which is conveyed through an elastic medium from a vibrating body to a listener.
v = 2x/t .......................................... Equation 1
making x the subject of the equation
x = vt/2........................................ Equation 2
Where v = velocity of sound in air, x = distance traveled by the sound, t = time
Given: v = 344 m/s t = 8 s
Substituting into equation 2
x = 344(8)/2
x = 1376 m.
x = 1376×0.00062 miles = 0.853 miles
<em>Thus the lighten travels 0.853 miles.</em>
Answer:
PHYSICS - Physics is the natural science that studies matter, its motion and behavior through space and time, and the related entities of energy and force. Physics is one of the most fundamental scientific disciplines, and its main goal is to understand how the universe behaves.
<u>SCIENCE -</u> Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe. The earliest roots of science can be traced to Ancient Egypt and Mesopotamia in around 3000 to 1200 BCE.
