### Why do I sneeze so many times?

Every time I sneeze, it's at least 5 in a row. My record (yes I count) is 16 times in a row. It doesn't matter where I am or if I'm sick or not. My mom does it too but she said she didn't start doing it until she was pregnant with me.

3 AnswersWomen's Health5 years ago### My friend's cat has a peeing problem?

Lately, he's been peeing on her bed and her chair in her room. The litter box is clean and accessible. We moved here about 3 weeks ago, maybe that has something to do with it? What could be making him pee on her stuff? She said he never did this at her old house, so she's completely confused, as am I.

7 AnswersCats1 decade ago### 18th birthday coming up?

I want to have a party but we are kind of short financially to throw a big party. So we can't rent out somewhere and have a DJ. But I don't want a boring party where my guests are bored in 10 minutes and we bum around for the rest of the day.

Does anyone have any ideas to make a party fun without spending a huge truckload of money?

1 AnswerOther - Science1 decade ago### Center of Mass help?

The question is as follows:

Show that the center of mass of a uniform semicircular disk of radius R is at a point 4R/(3pi) from the center of the circle.

I know that you have to take the integral and the basic equation for that is 1/A times the integral of xdA but I don't know how to determine what the x is. I know that the area of the semicircle is 1/2pir^2.

If anyone could tell me how to determine what the x would be.. that would be quite amazing.

2 AnswersMathematics1 decade ago### Physics question?

A skydiver falls through the air toward the ground at a constant speed of 120 mph, her terminal velocity, before opening her parachute.

If her mass is 55 kg, calculate the magnitude of the power due to the drag force.

After she opens her parachute, her speed slows to 15 mph. What is the magnitude of the power due to the drag force now?

Any help on this would be greatly appreciated! Thank you so much =]

2 AnswersPhysics1 decade ago### Physics help!?

A 3kg mass moving at 6 m/s is brought to rest in 2 sec. The magnitude of the net force acting on the mass is..?

I have the right answer, I just don't know how to get to it.

Help please! =[

1 AnswerPhysics1 decade ago### Physics help!?

A block of mass m1 is attached to a cord of length L1, which is fixed at one end. The block moved in a horizontal circle on a frictionless table. A second block of mass m2 is attached to the first by a cord of length L2 and also moves in a circle.

If the period of the motion is T, find the tension in each cord.

These are the answers in the back:

T2= [m2(L1+L2)](2pi/T)^2

T1= [m2(L1+l2)+m1L1](2pi/T)^2

I have absolutely no idea how they got those answers. Help pleeeease!

3 AnswersPhysics1 decade ago### Really intense AP physics question?

A 50kg pilot comes out of a vertical dive in a circular arc such that at the bottom of the arc her upward acceleration is 8.5g.

What is the magnitude of the force exerted by the airplane seat on the pilot at the bottom of the arc?

If the speed of the plane is 345 km/h, what is the radius of the circular arc?

You don't have to do all the math, I just have no idea where to even begin!

If you could help me out, it would be greatly appreciated!

Thanks!

7 AnswersJokes & Riddles1 decade ago### Physics dimensional analysis problem?

When an object falls through the air, there is a drag force that depends on the product of the surface area of the object and the square of its velocity. Fair = CAv^2. Where C is a constant. Determine the dimensions of C.

I know that Force is (kg)(m)/(s^2).

Area = m^2

v^2 = m^2/s^2

I have to find what units C has to have in order for both sides of the equation to be dimensionally correct.
