Answer: The drag force goes up by a factor of 4</h2>
Explanation:
The Drag Force equation is:
(1)
Where:
is the Drag Force
is the Drag coefficient, which depends on the material
is the density of the fluid where the bicycle is moving (air in this case)
is the transversal area of the body or object
the bicycle's velocity
Now, if we assume , and do not channge, we can rewrite (1) as:
(2)
Where groups all these coefficients.
So, if we have a new velocity , which is the double of the former velocity:
(3)
Equation (2) is written as:
(4)
Comparing (2) and (4) we can conclude the Drag force is four times greater when the speed is doubled.
Given: Change of x is 35.4m, Velocity Final=7.10 m/s, Velocity Initial=0m/s
Find: Acceleration
Analysis:
Vf²=Vi²+2aΔx (Velocity final squared equals Velocity initial squared plus 2 times acceleration times change of x)
(7.10 m²/s)²=(0 m/s)²+2a(35.4 m)
50.41 m/s²=(70.8 m)a
a=0.712 m/s²
A single sperm and the mother's egg cell meet in the fallopian tube. When the single sperm enters the egg, conception occurs. The combined sperm and egg is called a zygote. The zygote contains all of the genetic information (DNA) needed to become a baby.

If the gravitational pull is zero and I multiply by mass I get a zero
For part 2 number 1:
first multiply 3.0 by 20 to get 60. Then multiply 3.0 y 10 to get 30. Add both answers together to get 90. The answer is 90 meters per second squared.
