Answer:

Conservation of angular momentum

Explanation:

When the objects spread in universe after big bang, because of the tremendous force , they gained angular momentum and started to rotate. Since, then the object continue to rotate on their axis because of conservation of angular momentum. In vacuum of space there no other forces that can stop these rotation, therefore, they continue to rotate.

"The table represents the speed of a car in a northern direction over several seconds. Column 1 would be on the x-axis, and Column 2 would be on the y-axis."


typical plot is speed or velocity on the y-axis n time on the x-axis so the ans is Column 1 should be titled “Time,” and Column 2 should be titled “Velocity.”

A bird lands on a bare copper wire carrying a current of 51
nirvana33 [79]
The resistance of the piece of wire is
R= \frac{\rho L}{A}
where
\rho = 1.68 \cdot 10^{-8}\Omega m is the resistivity of the copper
L=5.1 cm=0.051 m is the length of the piece of wire
A=0.13 cm^2 = 0.13 \cdot 10^{-4} m^2 is the cross sectional area of the wire
By substituting these values, we find the value of R:
R= \frac{\rho L}{A}=6.6 \cdot 10^{-5} \Omega

Then, by using Ohm's law, we find the potential difference between the two points of the wire:
V=IR=(51 A)(6.6 \cdot 10^{-5} \Omega )=3.4 \cdot 10^{-3} V

Tests reveal that a normal driver takes about 0.75 s before he or she can react to a situation to avoid a collision. It takes ab
nata0808 [166]

To solve this problem we will apply the linear motion kinematic equations. On these equations we will define the speed as the distance traveled in a space of time, and that speed will be in charge of indicating the reaction rate of the individual. In turn, using the ratio of speed, position and acceleration, we will clear the position and determine the distance necessary for braking.

The relation to express the velocity in terms of position for constant acceleration is as follows

v^2 = u^2+2a(s-s_0)

Here,

u = Initial velocity

v= Final velocity

a = Acceleration

s_0 = Initial position

s = Final position

PART 1) Calculate the displacement within the reaction time

d = vt

d = (44)(0.75)

d = 33ft

In this case we can calculate the shortest stopping distance

0^2 = 44^2+2(-2)(s-33)

s = 517ft

PART 2)

PART 1) Calculate the displacement within the reaction time

d = vt

d = (44)(3)

d = 132ft

In this case we can calculate the shortest stopping distance

0^2 = 44^2+2(-2)(s-132)

s = 616ft

While a person without alcohol would cost 517ft to slow down, under alcoholic substances that distance would be 616ft
