IF all the pairs are separated by the same distance, then it's the car and the bowling ball.
If I can move them as far apart as I want, then I can make ANY of them have the greatest gravitational attraction between them.
Tommy runs around a track whose circumference is 400 meters. He runs a single lap in a time of 62 seconds. What is Tommy’s displacement
Answer:
Angular Displacement 6.28 radiansExplanation:
for circular motion we are expected to solve for Angular Displacement it is measured in radian
Measurement of Angular Displacement.
we can measure it using the following relation
∅= s/r
where
s = the distance travelled by the body, and
r = radius of the circle along which it is moving.
given that
circumference c, s= 400 m
r= ?
we have to solve for the radius
we know that circumference
[tex]c= 2\pi r[/tex]
400= 2*3.142*r
400= 6.282*r
divide both sides by 6.284 we have
400/6.284
r= 63.63 m
Angular displcament
∅= 400/63.63
∅= 6.28 radians

6. If a bicyclist, with initial velocity of zero, steadily gained speed until reaching a final velocity of 39m/s, how far would she travel
during the race in the same amount of time)?
Answer:
175 m
Explanation:
The average velocity for constant acceleration is the average of the beginning and ending velocities. That is (0+39)/2=19.5 m/s. If the bicyclist rides for 9 seconds, the distance traveled is ...
(9 s)(19.5 m/s) = 175.5 m
She would travel 175.5 meters in that time.
The distance traveled by the bicyclist at the same time period is 175.5 m.
Your question not complete, i believe it is missing this additional information below:
"Seven bicyclist are racing. Each bicyclist rides for 9s, If a bicyclist, with initial velocity of zero, steadily gained speed until reaching a final velocity of 39m/s, how far would she travel during the race in the same amount of time?"
The given parameter:
initial velocity of the bicyclist, u = 0
final velocity of the bicyclist, v = 39 m/s
time of motion of the each bicyclist, t = 9s
To find:
The distance traveled by the bicyclistLet the distance traveled by the bicyclist = s
The distance traveled by the bicyclist at the same time period is calculated as;
[tex]s = (\frac{u+v}{2} )t\\\\s = (\frac{0 + 39}{2} ) \times 9\\\\s = 19.5 \times 9\\\\s = 175.5 \ m[/tex]
Thus, the distance traveled by the bicyclist at the same time period is 175.5 m.

TRUE OR FALSE. For exponential growths, the growth in any doubling time is greater than the sum total of growth in all preceding doubling times
Answer:
False.
Explanation:
Doubling time is the amount time it takes for a population to double in size or quantity.
When the relative growth rate is constant, the population is undergoing exponential growth and the growth rate Is constant.
Exponential growth doubling time can be calculated using rule 70
Which is
Dt=70/r
R is rate.

1. If you move 5 meters East and 5 meters west what is the distance and what is the displacement?
2.if you move 5 meters south and move 2 meters north what is the distance and what is the displacement?
3. If you move 10 meters west and move 3 meters East
What is the distance and what is the displacement?
Answer:
1) dist 10m, displacement 0m
2) dist 7m, displacement 3m
3) dist 13m, displacement 7m
Explanation:
Distance is the total distance travelled (2 distances added), but displacement is where you end up relative to where you started.
Think of it like a number line. When you move east, you are adding 5, and when you move west, you are subtracting 5. In total, you have walked 10 meters, but overall you ended up in the same place.
If you want to have a physical demonstration of this concept, take 5 steps left and 5 steps right, and do the same with the other examples. You will probably get a fuller understanding of this concept.
What is the net force exerted by these two charges on a third charge q3 = 54.5 nC placed between nC and nC at x3 = -1.145 m ? Your answer may be positive or negative, depending on the direction of the force.
Answer:
[tex]-4.74*10^{-5}\ N[/tex]
Explanation:
Consider two point charges located on the x axis: one charge, q1 = -19.5 nC , is located at x1 = -1.670 m ; the second charge, q2 = 34.0 nC , is at the origin (x=0).
Given that:
q1 = -19.5 nC , x1 = -1.670 m, q2 = 34.0 nC , x2=0, q3 = 54.5 nC, x3 = -1.145 m
From Coloumbs law, the force between two charges is given by the formula:
[tex]F=k\frac{q_1q_2}{d^2}\\ \\Where\ k=\frac{1}{4\pi \epsilon_o}=9*10^9\ Nm^2/C^2 ,\epsilon_o=8.854*10^{-12}\ C^2/Nm^2\\d=distance\ between\ charges[/tex]
Hence the force of attraction of q1 on q3 is given by:
[tex]F_{13}=k\frac{|q_1q_3|}{(x_3-x_1)^2}=9*10^9(\frac{|-19.5*10^{-9}*54.5*10^{-9}|}{(-1.145-(-1.670))^2} )=3.47*10^{-5}\ N[/tex]
Hence the force of attraction of q2 on q3 is given by:
[tex]F_{23}=k\frac{|q_2q_3|}{(x_3-x_2)^2}=9*10^9(\frac{|34*10^{-9}*54.5*10^{-9}|}{(-1.145-0)^2} )=1.27*10^{-5}\ N[/tex]
The force of attraction of q1 on q3 is in the negative direction and force of attraction of q2 on q3 is in the negative direction. Hence the net force is:
[tex]F_{NET}=-F_{13}+(-F{23})=-3.47*10^{-5}-1.27*10^{-5}= -4.74*10^{-5}\ N[/tex]

Read the passage about the health risks of single-load liquid laundry packets. These packets are filled with concentrated, toxic chemicals. A 7-month-old in Florida died from swallowing the soap. Several soap and detergent companies are conducting studies to address these safety concerns; they want to reduce toxicity and to make the packets look less like candy. The U.S. Consumer Product Safety Commission (CPSC) is also performing studies to build more safety into these products. Why would the CPSC perform studies when other soap and detergent companies have already conducted research on the same products? The CPSC is the only organization that can test the safety of soaps and detergents. Studies conducted by any company that benefits financially are considered unreliable. Studies performed by the CPSC give reliability to the results of improved safety obtained by each soap company.

A cathode ray tube is made of glass with a small amount of some kind of gas in it. It has metal electrodes at each end to pick up an electric current. The electrodes are named "positive” and "negative,” which were words used by Benjamin Franklin in the 1700s to describe electricity. A bright ray forms in the gas when an electric current is applied to metal electrodes. In the 1800s, an important scientist suspected that the negatively charged particles in a cathode ray were present in all atoms
Answer:
Make cathode-ray tubes with various materials and see whether the beam should be the same.
Explanation:
Cathode ray tube seems to be a transverse wave or vacuum tube throughout which the electron beam becomes transmitted onto a phosphor-coated panel to create a luminous position at that same point on a surface established either by influence on the electron beam of the varying magnetic field inside the container.This beam flowing from either the negative (-) charge portion including its vacuum (cathode) to something like the positive (+) charges plate (anode).URGENT!

Answer:
Option D (none are correct) is the appropriate solution.
Explanation:
After yet another workout, a cool or calming down allows the breathing as well as pulse rate to recover more quickly. It will also assist to eliminate the lactic acid build-up during the exercise, eventually increasing the muscle soreness with delayed onset. Wind yourself off for 5 to 10 minutes by taking public transportation a stationary bicycle.Some other three scenarios do not correspond to something like the situation described.
