Two identical capacitors are arranged in a circuit. What is the ratio of the equivalent capacitance of the circuit when the capacitors are in series to that when they are in parallel?

Answers

Answer 1

Answer: Ceq in series is calculated by 1/C1 + 1/C2 + ....
While, in parallel, Ceq= C1 + C2 + ...

So the ratio is 1/Ceq = Ceq

after the box has left the rubber band but is still moving upward, what is the passenger's apparent weight?

Answers

If the upward acceleration is equal to the acceleration due to gravity ( $9.8 m/s^2$ ), then the apparent weight would be zero, indicating that the passenger is experiencing weightlessness or is in a state of free fall.

When the box has left the rubber band but is still moving upward, the passenger's apparent weight would be less than their actual weight.

The apparent weight of an object is the force exerted on it by a supporting surface, which in this case is the floor of the box. It is equal to the normal force acting on the object.

As the box accelerates upward, there are two main forces acting on the passenger: the gravitational force (weight) pulling them downward and the normal force pushing them upward. The normal force is responsible for providing the upward acceleration to the passenger.

Since the passenger is moving upward, the normal force exerted by the floor must be less than their actual weight to create the net upward force necessary for upward acceleration. Therefore, the passenger's apparent weight is reduced.

The exact value of the apparent weight depends on the magnitude of the upward acceleration and the mass of the passenger. The apparent weight can be calculated using the equation:

Apparent weight = Actual weight - (Mass of passenger * Magnitude of upward acceleration)

Find the perimeter of the rectangle if each block represents one foot(show your calculation)

Answers

I'm pretty sure that the "block" of which you speak is one in a pattern
of them that covers the drawing you have of the rectangle, and now
I need to explain something to you:

The REASON for printing that drawing next to the question that you
partially copied is that the drawing has information that's needed to
answer the question with, and rather than repeat all that information
in the question, it just says "LOOK AT THE DRAWING !"

In fact, the whole point of the question may not be just to remind you of
what "perimeter" means. It's more likely that the purpose of this problem
is to make you pick the information you need off of a drawing.

Either way, if you'll kind of "read between the lines" of the part of the
question that you DID copy, it should be pretty obvious to you that nobody's
going nowhere in the direction of a solution without SEEing the drawing.

So my bottom-line conclusion regarding a solution for this problem is:
Not possible with the given information.

Can someone tell me some variables that could affect how far a ski jumper could travel in the air and explain the science behind it ? Thanks you will help me a lot if you can answer it !

Answers

Some things you could take into consideration are the weight of the jumpers. There height, well more like overall mass. Gravity would be another key factor. The angle at which she jumped could be another variable. Wind resistance could be another important thing. How far she is attempting to jump is an important variable.

Those are just some of the basic things.

Hope I helped. :)

Performance in ski jumping is determined not only by the motor abilities of the athlete, but alsoto a large extent by the aerodynamic features of the equipment used and by a low body weight. Manyski jumpers were extremely underweight to the point of having a body mass index (BMI =m/h2of16.4 kgm−2(heighth= 1.73m, body massm= 49 kg)

B) Find a(t).

C) At t=0, is the particle slowing down or speeding up? Explain.

D) At what time(s), if any, does the particle change directions? Justify your answer.

Any help would be GREATLY appreciated! Thank you!!!

Answers

for speed you can differentiate the equation, for acceleration you can again differentiate the equation .
at t=0 the particle is slowing down , when you get equation for velocity put t=0 then only -1 is left
