How many quarters in 7 and three quarters?
There are 28 Quarters Feel free to check my answer... 8 x 4 = 32 32 - 4 = 28 7 and 3 quarters is 7+(3/4) So 7 x 4 = 28 28+3=31 31 is your answer
How many meters will a 2kg ball moves starting from rest fall freely in one second?
The mass is irrelevant. If the object is in free fall (that is, air resistance can be neglected), an object will fall 4.9 meters in one second.
What is the speed of an object in free fall 2 seconds after falling from rest?
Acceleration of gravity near the surface of the earth is 9.8 meters (32.2 feet) per second2. Downward velocity after 2 seconds = 19.2 meters (64.4 feet) per second.
What is the average value of a pound of mixed nickels quarters peniies and dimes?
I just counted my change jar (8 lbs 1.2 ounces) and found $108.86 in change. That's $13.48 per pound. That being said, I expect this number can vary considerably with personal habits. I hate loose change, and I take it out of my pockets as soon as I can. I rarely ever hand cashiers any change, even if I have some on me. I also don't use quarters for anything since sodas are free at my workplace (yay!) and I have my own laundry machines. Quarters accounted for 73% of my total, so taking them out would certainly skew the numbers. I saw one estimate on everything2 for $10.60 per pound, which is in the same ballpark as mine. I saw another estimate on worldofstuff for $4.80, which is much lower. I imagine that this is a person who spends their quarters. So: About 5 dollars per pound if you spend your quarters, and 12 dollars per pound if you don't.
A squirrel drops a nut over a cliff what is the velocity of the nut after 3 seconds?
Ignoring air resistance, the velocity of any object that goes off a cliff is 29.4 meters (96.5 feet) per second downward, after 3 seconds in free-fall.
