A wood block measures 3cm in length, 4cm in width, and 5cm in height. The block has a mass of 180 grams. What is the block's density?

Finding volume:

V(wood)=l×b×h=3×4×5=60cm³

we have been given the mass of the wood as 180 grams and we know that"

Density = mass/ volume

substituting in the mass and volume

=> D=180/60=3g/cm³

i'm assuming that the correct answer is indeed the first one/ "a"..

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
