121 beats per minute...?

(just guessing here...)

Actually, you're not far off :D. The average 2 year old should have a heart rate falling within the range of *roughly* 80-130 beats/minute. A normal adult should have a pulse somewhere between 60-100 beats/minute.

Bonus points: What's the medical term for a heart rate that's faster than the normal range? Slower? (can you tell I have my EMT certification, by the way ;) ).

Um... I have no idea.


Q: Explain a nuclear chain reaction.

The short answer is that a nuclear chain reaction happens when a nuclear reaction (a nuclei or nuclear particle collies with others to produce a new substance) causes more than one other nuclear reaction. An uncontrolled chain reaction within a large enough amount of fuel leads to one big bang ;).

By the way, tachycardia is a heart rate of above 100 beats/min.; bradycardia is a heart rate below 60 beats/min.

What's the common name for the animal that bears the scientific name Aptenodytes forsteri?

Olorin, come on down! You're the next contestant on the "Answer is Right"!!!!! :)

My questions, insane as they are, might even be responsible for sending you into SVT (superventricular tachycardia, a HR of over 150 beats/min). I'll just make sure my nearly-Paramedic hubby is standing by with his ambulance before I post any more in this thread ;) *glares at and sticks out tongue at said hubby, who still won't let me get a pet penguin*

What's the atomic mass of the element symbolized as Sn?
 
I'm not familiar with that particular acronymn...I'm guessing others arent either?

Q: how many yoctograms are in 1 gram? (HINT: a LOT...it's the smalled prefix in the metric system)
 
You are correct. However, you forgot to post a question. :p

What is a half-life? (Sorry, I know these aren't real challenging...but I can't think of much.)

Where is the horsehead nebula located and what is its significance ?
Click to expand...

The horsehead nebula is located in the constellation Orion, the hunter. I'm not sure of the significance, except that the ionized gasses create it's distinctive shape and emit a magnetic field.

My question is in the form of a photo. Since we're on the subject of Astronomy, identify the constellation in the photo below. What is the name of its brightest star? Here's a hint: The constellation is one of the oldest recognized and is prominant in the Northern Hemisphere around this time of the year. It has a right ascention of 11 hrs. and a declination of 15 degrees.
