The correct answer makes sense, but I don't understand the mechanism in terms of nucleophiles and electrophiles. If...
Homework Statement
I have to list out some ways on how to determine the manganese content of a steel sample.
The Attempt at a Solution
I can only think of one right now, which is calorimetry...but I was wondering are there other simpler possible ways of determining it?
If I know the theoretical acc down is 9.8 and I have the actual acceleration to be 9.2, do I use 9.8-9.2 to find the air resistance force? Or do I use 9.2-9.8?
And then after that, do I multiply it by the mass? Or do I calculate both forces and then subtract them?
Homework Statement
Say there were 2 balls of different masses projected at the same angle and subjected to the same air resistance. Will the heavier ball reach a higher maximum vertical height than the smaller ball or vice versa?
This is for my school experiment for projectile motion. I...
How is it that the water in a bucket, spun fast enough, does not spill?
The formula at the top would be Total Force = Tension + M*g right?
So would the tension be let as 0? If so, why? I can't understand how the water just simply does not fall out of the bucket :confused:
I'm a bit confused because the ball needs to go down to the water so it will go up, then go back to the same height as the bridge, and then go back down 9.5 m to the water...so total time shouldn't be 0.5 seconds
Hi :)
I thought t=0.5 was the time it takes for the ball to go up, and then reach the same height as the bridge. So with the Sh=Uh*t formula shouldn't the "t" be total time it takes for the ball to fall down again?
On that thing, I am trying to find the final velocity so I can find the total "t"
Homework Statement
The bridge is 9.5 m above the water and using his watch, Andrew measured the time it took for a stone, thrown by David to return to the height of the bridge to be .5 seconds.
a. what is the vertical velocity with which the stone left David's hand?
b. how high did the stone...
I know this is the formula but apparently in this experiment, I'm supposed be only using the mass to find the centripetal force because the masses are hanging off the bottom of the string while the top is being whirled around.
