Measuring Density 70.0g
Sphere in 100 mL Sphere on balance
of water
In the first picture above, the sphere is in a beaker with 100 ml of water. In the second picture, the dry sphere is being massed. What is the density of the sphere?
D= MV

the answer is d : ) have a good da

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.

i believe the answer is 5,000
