Answer:
(A) 19 bars
Explanation:
First off, we calculate the mass of platinum contained in one 1 L bar. To do that we convert 1 L into cm³ -1 L equals to 1000 cm³-.
21.4 g/cm³ * 1000 cm³ = 21,400 g
Each bar of platinum weighs 21,400 grams.
Now we convert the maximum payload capacity of the truck, into grams (1 lb equals to 453,592 g):
![900lb*\frac{453,592g}{1lb}=408232.8g](https://tex.z-dn.net/?f=900lb%2A%5Cfrac%7B453%2C592g%7D%7B1lb%7D%3D408232.8g)
Then we divide the weight of one bar by the maximum payload capacity:
408232.8 / 21400 =19.09
Thus the thieves could carry 19 1 L bars
Answer:
the process of cellular respiration helps excrete carbon dioxide, as well as generate ATP through aerobic respiration.
<span> C + H2O → CO + H2 - this reaction is balanced,
1 mol C 1 mol C
2 mol H 2 mol H
1 mol O 1 mol O</span>
The magnitude of the force causing this acceleration is 15 N
<u>Explanation:</u>
we know that
F=ma: According to the newton's second law
F - force acting on the object
m - mass of the object
a - acceleration
Newton's second law states that acceleration depends on force acting on the object and mass of the object.
Force is directly proportional to acceleration and mass is inversely proportional to acceleration.
here,
m = 5 kg
a = 3 m/s2
![F = m \times a\\F = 5 \times 3\\F = 15 N](https://tex.z-dn.net/?f=F%20%3D%20m%20%5Ctimes%20a%5C%5CF%20%3D%205%20%5Ctimes%203%5C%5CF%20%3D%2015%20N)
