What is the relationship between the number of resistors ,the effective resistance of the circuit and the total current in parallel
Answer:
As more and more resistors are added in parallel to a circuit, the equivalent resistance of the circuit decreases and the total current of the circuit increases. Adding more resistors in parallel is equivalent to providing more branches through which charge can flow.

Explanation:
1. Mass of an object
2. Distance between the objects
Answer:
When dealing with the force of gravity between two objects, there are only two things that are important – mass, and distance. The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them.

en and Karen are travelling for the weekend. They both leave from Jen's house and meet at their destination 250 miles away. Jen drives 45mph the whole way. Karen drives 60mph but leaves a half hour after Jen. How long does it take for Karen to catch up with Jen
Answer:
1 1/2 hours. for Karen to catch Jen.
Explanation:
Karen needs to make up 22.5 km which is the distance Jen travels in 1/2 hour.
The distance where they meet must be equal from the starting point.
Jen
Jen is out 1/2 hour longer.
Let the Karen's time = t
d = r * t
d = 45 * (t + 1/2 hour)
Karen
d = 60 * t
The distances are equal
so
Meeting time
45*(t + 1/2 hour) = 60 * t
45t + 22.5 = 60t Subtract 45t from both sides
22.5 = 15t Divide by 15
t = 22.5 / 15
t = 1 1/2 hours = 1.5 hours.
Now you have to interpret the results.
Remember that Jen has travelled 1/2 hour more than Karen
Her time is 2 hours.
Karen's time is 1.5 hours.
Jen travels 2 hours which is 2 * 45 = 90 miles
Karen travels 1 1/2 hours which is 1.5 * 60 = 90 miles

A STONE IS THROWN VERTICALLY UPWARD WITH THE VELOCITY 25/s HOW LONG DOES IT TAKES TO REACH THE MAXIMUM HEIGHT?
Answer:
time taken to reach maximum height is 2.548 sec and Maximum height is 31.855 m
Explanation:
Initial velocity U= 25 m/s
at maximum height velocity, V= 0 m/s
Let the time taken to reach maximum height be t and maximum height be H.
V= U-gt
so 25-9.81.t=0
therefore t= 25/9.81 = 2.548 sec
Now,
H= Ut-1/2(gt^2)
=25x2.548-0.5x9.81x(2.548^2)
=31.855 m

Imagine that you tested 20 high school students (15 male, 5 female). Twelve males and four females reported feeling a calming effect after exposure to the color blue.
In two to three sentences, explain what conclusions could be drawn from this information.
Answer:
Answer:
Explanation:
It means that out of 20 students, 3 males and 1 female were digital screen addicts because they were getting dangerous amount of blue light. Thus couldn't feel calming sensation that a human feels while seeing blue light. The rest students were getting balanced blue light. So they were getting relaxed feeling while being exposed to blue light.

A soccer ball is kicked horizontally. What is its average speed if its displacement is 21.0 m
after 2.00 s?
Answer:
Below
Explanation:
You can use this formula to find the average speed/velocity
speed = displacement / change in time
Plugging our values in....
speed = 21.0 m / 2.00 s
= 10.5 m/s
Hope this helps! Best of luck <3
The average speed of a soccer ball is 10.5 m/s.
What is speed?Speed is defined as the ratio of the distance moved by the object at a particular time. The unit of speed is measured in the meter per second, miles per hour, etc. The speed of an object is a scalar quantity and does not require any direction to represent it. It only requires magnitude to represent it.
Average velocity is defined as the sum of all the distances traveled by an object to the time taken by the object to cover the total distance.
Given that a soccer ball is kicked horizontally. its average speed if its displacement is 21.0 m after 2.00 seconds will be calculated as below:-
Speed = displacement / change in time
Speed = 21.0 m / 2.00 s
Speed = 10.5 m/s
Therefore, the average speed of a soccer ball is 10.5 m/s.

4. A sprinter begins from rest and accelerates at the rate of 2 m/s2 for 200 m.
a) What is the sprinter's velocity at the end of the 200 m?
b) How long does it take him to cover it?
c) What is his average velocity?
Answer:
v=28.28m/s t=14.14s average velocity =2m/s
Explanation:
Starting at rest the initial velocity is 0 substituting that in the first equation of motion v=u+atgives the final velocity but we first have to determine the time using the third equation of motion which is s=ut+1/2at^2 and then do the substitution. Average velocity is the determined by adding the initial and final velocity then divide it by 2

12. A measuring cylinder has 150ml. of water in it. When a stone is immersed into the measuring cylinder, the water level raised to 210cm. What is the volume of the stone?
Answer:
60ml
Explanation:
I'm going to assume you mean 210ml not centimeters. To find the volume all we do is subtract both values or with the formula [ f - i = v ] where f = final amount and i = initial amount.
210 - 150 = 60ml
Best of Luck!
The final level of water should be = 210

or 210 ml
━━━━━━━━━━━━━
Given:.Initial level of water = 150mlFinal level of water = 210 ml━━━━━━━━━━━━━

E (in) = 1000 J
Heat input : 1000J
What is efficiency of a heat engine ?
The efficiency of a heat engine is defined as the ratio of work done by the heat engine absorbed per cycle.
Given : work output = 400 J
Efficiency = 40 % = 0.4

what colors are included in our visible spectrum?
ALL colors are in the visible spectrum.
"Color" is a word we use to describe light that our eyes can detect. If the light has a "color", that means we can see it, and somebody gave it a name. If we can't see it, then we don't have a "color" to describe it.
Every color that has ever been perceived by human eyes is present in the humanly-visible spectrum, except "black".
There are at least hundreds of them. Probably thousands. Maybe millions.
The Colours that are included in visible spectrum are - 7 Colours namely :
Red Orange yellowgreen blueindigovioletExplanation:
when white light passes through a prism , the violet light bends most and the red light bends the least.Dispersion of light is the phenomenon of splitting of white light into its constituent seven colours on passing through a glass prism.The band of seven Colours so obtained is called visible spectrum.The seven Colours of white light are Violet, indigo , blue, green , yellow, orange and red .
