what did you get
I got density
that is correct density = mass/volume
yaya!!! I have another question
write 6.3 · 10-5 as a number A. 0.063 B. 0.0063 C. 0.000063 D. 0.00063 Wouldnt it be C??
yep, move the decimal 5 spots to the left
can u try your best to correct my questions?
what kind of questions, science?
yep, easy question
ok it'll depend, but i'll give it my best shot
How do an astronaut mass and weight on the earth compare to those on the moon? A. mass and weight are both different B. mass and weight are both the same C. mass is different weight is the same D. mass is the same, weight is different
what did you get
you have it flipped, mass would stay the same (they don't lose any particles of mass), but the weight would be different
since the force of gravity on the moon is smaller
which of the following describes the correct way to handle a test tube that is being heated in science lab? A. light a match above the test tube to test wheather the released gas is flammable B. move the test tube below your nose so you can easily observe the released gas C. point the container away from yourself and your lab partners to avoid injury D. point the container toward yourself so that others wont be affected by the chemicals
I got B
hmm unless you know what the gas is (and if it's not toxic), then B would be fine
but most of the time you don't know the gas and if it's toxic or not
A is just stupid and will most likely lead to a fire
yep, D is just as stupid too when you can do C
write 7,200,000,000 in scientific notation A. 7.2*10^8 B. 7.2*10^7 C. 7.2*10^10 D. 7.2*10^9
you got ???
I got D
me too, it's 7.2 billion
write 9.4*10^-2 as a number A. 0.094 B.0.94 C. 9.4 D. 0.0094
I got D
move the decimal 2 spots to the left
oh A right?
if you accidently mixed two different liquids in an expiriment and found that the mixture was bubbling, what should you do? A. observe and record what happens next B. pour the mixture imedietly into a nearby sink C. report it to the teacher immedietly D. write it your loabrotory report under the conclusions section
wouldnt it be either A or C?
probably C since it could be hazardous, but you don't know
better be safe than sorry
yes thats very true lol!
it definitely wouldn't be B because you could be pouring toxic chemicals down the drain which would end up in a local river or stream
or the ocean
in significant figures, which zeros are NOT considered significant? A. zeros before a digit, but after a decimal B. zeros between two non-zero numbers C. zeros in a whole number before a stated decimal D. zeros in a whole number before an implied decimal I think its A
either A or D I think
hmm which one should we choose then?
something like 0.000000501 has 3 sig figs (5, 0, 1) because the zeros in front aren't counted
something like 7,000,000 has only 1 sig fig
but if you said 7,000,000.0, then it would have 7 sig figs
so then we should pick A right?
D could be lumped together with C somehow, not sure though
so I would think D is partially true, which means we can eliminate it
so yeah, A
which one of the following is true about scientific throry and scientific law? A. a scientific law can be changed, while a theory is absolute B. a scientific theory can be changed, while a scientific law is absolute C. Both scientific law and scientific theory are absolute and cannot be challenged D. both scientific laaw and scientific theory can be challenged
I got A
actually I think they both can be absolute but not chalanged
what do you think I got C for my answer now
I would think that a law is absolute, but a theory can be challenged
if it couldn't be challenged, then it would be perfect and there wouldn't be any flaws
oh alright, so then B would be a reliable answer?
yeah B sounds better
what does a centi represent? A. 10^-3 B. 10^-2 C. 10^2 D. 10^3
centi = one-hundredth
hey jim sorry my computer died
u still here
I got b for the last question about the centi
yes that's correct
how many millimeters are in 1.6 liters?
you mean milliliters?
1,600 right? and yep:)
yeah 1600 mL
is the mass of the force if gravity on an object? A. volume C. mass C. matter D. weight
what did you get
I got weight
is that correct?
what is the base unit for mass in the international system of units (si) A. gram B. kilogram C. ounce D. pound I got a kilogram
Which of the following is equivalent to 16mL? A.16cm^3 B.16 gallons c.16 liters D. 16m^3
I got A
which of the following is a temperature represented in metric system scale? A. 4mL B. 30 degree C C. 68 k D. 85 degrees F
I got B
write 0.72 in scientific notation I got 7.2*10^-1
you're on a roll
thanks! write 9.4*10^5 as a number A. 940,000 B. 9,400 C. 94,000 D. 9,400,000
you got what
I got C as my answer
@jim_thompson5910 were did ya g? lol
C is wrong
sry the site is glitching on me
and going slow too
hey u their?
if cathys height is 66 inches, what is her height in centimeters equality statment 1 in=2.54 cm A. 10.23 cm B. 25.98 cm C. 167.64 cm D. 425.81 cm
I got B
you multiply by 2.54, not divide
in what way does science helps us to catagorize the world? A. chemically B. effortlessly C. emotionally D. physically
I think its D
D sounds right, but it might be A
D sounds like a better fit though
write 9.4*10^5 as a number A. 940,000 B. 9,400 C. 94,000 D. 9,400,000
is it b?
B would be 9.4*10^3
you would move the decimal point 5 spots to the right
ohhh lol then A
thanks fer yer help:)!!
