Answer:
the force applied to the rubber band is -9.3N
Explanation:
The computation of the force applied to the rubber band is shown below;
We know that
Force in newtons = Spring constant × amount of extension
F = -k × x
where
-k = 62 N/m
And, x = 0.15m
So, the force applied is
= -62N/m × 0.15m
= -9.3N
hence, the force applied to the rubber band is -9.3N
Answer:
a. The second run will be faster.
d. The second run has twice the surface area.
Explanation:
The rate of a reaction is proportional to the surface area of a catalyst. Given the volume (V) of a sphere, we can find its surface area (A) using the following expression.
The area of the 10.0 cm³-sphere is:
The area of each 1.25 cm³-sphere is:
The total area of the 8 1.25cm³-spheres is 8 × 5.61 cm² = 44.9 cm²
The ratio of 8 1.25cm³-sphere to 10.0 cm³-sphere is 44.9 cm²/22.4 cm² = 2.00
Since the surface area is doubled, the second run will be faster.
The answer is that "<span>Ag+</span> ion combines with the chloride ion to form a precipitate".
Silver chloride is formed in the form of precipitates, Ag⁺ is a cation and Cl⁻ is an anion so both ions attract each other and combines to form AgCl.
The equation for the ionic reaction that occurs is;
<span><span>Ag</span></span>⁺(aq)+Cl⁻(aq)→AgCl(s)
Symbiosis describes close<span> interactions between two or more different species. There are four main types of symbiotic relationships: mutualism, commensalism, parasitism and competition.</span>
1st place is in the air !
carbon dioxide has carbon in it and we release it all the time, when we're awake and when were asleep.
another place would be the gas that cars release. this gas is known as carbon monoxide.
