Answer: A Because 29.9 but it was probally rounded off.
Step-by-step explanation:
Answer:
about 1099 pounds
Step-by-step explanation:
The weight of the truck is directed downward. It is countered by a force normal to the plane of the hill and one that is parallel to the plane of the hill. The question is asking about this latter force.
The magnitude of the force parallel to the hillside required to keep the truck stationary is ...
(2600 lb)·sin(25°) ≈ 1098.81 lb ≈ 1099 lb
The answer is B.
in the original equation, CH4 + O2 → CO2 + H2O, there are:
REACTANTS: 2 carbon, 4 hydrogen, 2 oxygen
PRODUCTS: 2 carbon, 2 hydrogen and 1 oxygen.
If we change the equation to this,
CH4 + 2O2 → CO2 + 2H2O, then there are now:
REACTANTS: 2 carbon, 4 hydrogen, 4 oxygen
PRODUCTS: 2 carbon, 4 hydrogen, 4 oxygen
and thus the equation is balanced
Step-by-step explanation:
from the question:R=x^2/y
where x=3.8*10^5
y=5.9*10^4
it then mean
R=(3.8*10^5)^2/5.9*10^4
=144400000000/59000
=2447457.63
