Answer:
C. 0.006 g/cm³
Step-by-step explanation:
As the units tell you, density is the ratio of mass to volume. The volume of the container is found from ...
V = πr²h = π(10 cm)²(25 cm) = 2500π cm³
Then the density is ...
ρ = (50 g)/(2500π cm³) = 1/(50π) g/cm³
ρ ≈ 0.006 g/cm³
_____
<em>Comment on the problem</em>
The "liquid" has about the same density as air pressurized to 75 psi.
There is no statements to choose from
Answer:
I think its A
Step-by-step explanation:
Answer:
Speed of car B is 33 km/h and speed of car A is 
Step-by-step explanation:
Let speed of car B be 
km/h
Speed of car A is 12 km/h more than car B.
Therefore,
Speed of car A = 
km/h
Distance = Speed × Time
Distance travelled by car A in 4 hours = 
km = 
km
Distance travelled by car B in 4 hours = 
km
Also, cars A and B are 312km apart after 4 hours.
Speed of car B is 33 km/h and speed of car A is 
The change in temperature is -28°F
So, Option D is correct.
Step-by-step explanation:
Temperature at day time = 72°F
Temperature at night = 44°F
What number represents the change in number?
Change in temperature = Temperature at night - Temperature at Day
Change in temperature = 44°F-75°F
Change in temperature = -28°F
The change in temperature is -28°F
So, Option D is correct.
