The answer would be 1800. Why? bc if you're going 30 meters per second and trying to figure out how far you would go in a minute, you would multiply 30 x 60 bc there's 60 seconds in a minute. Giving you 1800 meters. hope this helped, have an amazing day :)
This theory was first proposed by Nicklaus Copernicus. Copernicus was a polish astronomer. He first published the heliocentric system in hes book: De revelation erbium comestible, "In revelations of the heavenly bodies," which appeared in 1543. HOPE IT HELP:)
Answer:
c. 80 g
Explanation:
metal alloy:
- wt% = (mass compound/mass alloy)×100
for antimony:
⇒ 16% = (g antimony / g alloy)×100
⇒ 0.16 = g antimony / g alloy
∴ g alloy = 500 g
⇒ (0.16)×(500 g) = g antimony
⇒ g antimony = 80 g
Answer:
(a) 0.0345 g/cm^3
Explanation:
<u>Given:</u>
Edge length of cube (a) = 0.750 m
Mass = 14.56 kg
<u>To determine:</u>
The density of the cube
<u>Calculation:</u>
Unit conversions:
1000 g = 1 kg
Therefore, the mass of cube in g = 14.56*10³ g
10⁶ cm³ = 1 m³
Therefore the volume of the cube in cm³=0.422*10⁶cm³
Based on equation (1)
