Mercury, with a freezing point of -38.8°C, is the only metal that is liquid at room temperature. How much heat energy (in joules) must be released by mercury if 1.30 mL of the metal is cooled from room temperature (18.0°C) to -38.8°C and then frozen to a...

How do I set up the quadratic equation for this problem? 4.0= (2x)^2 / (1.0-x)(1.0-x) I know how to use the formula, but I have a hard time setting those equation to zero. Please explain step by step. Thank you

we have a test coming up and I cannot figure out the practice question. Can somebody please help? Aaron throws a 7.5 kg bowling ball by applying a 45 N force for a time of 0.90seconds. What is the impulse Aaron applies to the ball? What is the ball's spee...

What is the electric field at a point midway between a -7.34 micro coulombs and a +4.49 micro coulombs charge apart 31.5m apart?

Find the ratio and simply. Triangle find the shortest side to the longest 22.2, 9.6, 20 The simplified ratio is Type ratio as a simplified fraction

Find the point on the curve y=2x+5 closest to the point (0,9). I know to use the distance formula but I cannot get a correct answer

Find the points on the curve y=x2+2 closest to the point (0,3). Round to the nearest two decimal places. I know this requires the distance formula.

A submarine submerged at a depth of -35.25 meters dives an additional 8.5 meters. What is the new depth of the submarine?

The slope formula is Y2-Y1 over X2-X1 Therefore, it would be 6+8 on top, and 0-3 on the bottom.

0+3 on the bottom Sorry

I don't no because

I think it's 48 so check my answer please

Im still very confused on what to do with those values

okay, yeah, I got really confused with the derivative and how to solve to get w

that answer is not the one I need, I need two that are on either side of the 0

it didnt work out to be correct.

I checked the math

it had to have the square root in it still

m=26600000kg P=2000W d=2000m t=? P=W/t=Fd/t Forces that act on the object are Force that the pump applies (upward) and Fg (downward). Fnet = F - Fg = 0, so F=Fg=26600000 *9.81 t=Fd/P=2.61*10^8 s
