Hope that helps you, Good luck!
For solving this we need the change in distance and the change in time. You said that the change in time is 1.8 seconds and the change in distance is 3.6 meters. ( This is assuming it started at 0 meters and started at 0 seconds )
Since the starting was 0,0 we can toss them out as they add no value. Now since speed is labeled (in this case) m/s, we divide how many meters it traveled over how many seconds it took to travel it.
3.6 / 1.8 = 2
The average speed of the cart is 2 m/s
31 out of 50 is
62%Divide 31 over 50:
Multiply 0.62 and 100. This will convert the decimal to a percentage:
Answer:
If the complement of an angle is 25 degrees, then the measurement of the angle will be 65 degrees.
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.
