n one experiment, the mass of the metal block is 93.3 grams, the volume of water used is 96.3 mL, the temperature of the cold water extrapolated to the time of mixing is 20.4oC, and the temperature of the metal block and water extrapolated back to the time of mixing is 28.7oC. The specific heat of water is 4.184 J K-1g-1

PE =mgh = 0.1* 9.8 * 0.80 m = 0.784 J

x-5x=2(-3x+4)

oops. but would the answer be correct if everthing was factored in?

what kind of triangle is it. and on what side?

72/9= 8 hours so double the weight at the same rate? 144/9= 16*12= $192

315

youre right. i misread the problem

same rate as in she picks 9lbs/hr. if that's what shes asking. not clear

its 180

im assuming youre talking about an equilateral triangle. the perimeter is A+b+C=18 and one side is 2x-1 so so 2x-1+2x-1+2x-1=18 combine like terms 6x-3=18 so 21/6=x x=3.5

are you just asking for rearrangement? if so, (s+24)/3=f

yeah just plug in the 15 for s into your formula and rearrange to find f, foot length

13 in is the length of the foot if its a size 15 shoe. that's a big foot

they might be products of the proof that derived that formula

i don't know what youre question is

You have a quantity of one compared to another quantity. example: 1cat/5Dogs For every 5 dogs, you'll have 1 cat.

KE=1/2*m*v^2 solve for v

look up hess's law. you should be able to figure it out

F= frank, B= Buds F+B=56 b=f*8 plug in the equivalence and solve for f

All you need to do is FOIL

this seems incomplete. is there anything else?

I'm assuming your asking how is the energy conserved? If so, it is in the form of ATP

Oxidative phosphorylation

during the ETC

e=mc^2 solve for m

$5=F $2=T F+T=500 5F+2T=$1450 solve for either variable on either equation and plug into equation you did not use. the rest should pretty straightforward from there

x kg * (y lbs/ x kgs) = y lbs

i don't know how you got 105. it should be 90. so, -10x=90 divide by -10

oops y lbs * (x kg/ y lbs) = x kg

before you actually apply these equations you need to know the equivalences between the two units being analyzed

what are you asking for?

well if the system loses heat E, delta H is - , if the system requires an input of energy delta H is +

correct

1) KE=1/2*m*v^2 (KE*2)/v^2=m 2) KE=m*v^2 use the mass we found and convert mph to m/s

2) KE=1/2*m*v^2 sorry about that.

1. wrong, eye cells are somatic, while egg cells are not. 2. correct. 3. wrong. 78 homologous pairs would equal 156 total chromosomes.

yes

Transition metals exist in many oxidation states.
