A force of 3000N is applied on a 20kg ball. Find the acceleration of the ball

Andrews [41]

Answer:

force = 3000N

mass= 20 kg

now

F= ma

3000= 20×a

3000÷20=a

a=15

F= ma by newtons second law of motion

Sulfur reacts with oxygen and creates two compounds. Compound A contains 1.34 g of sulfur for every 0.86 g of oxygen. Compound B

spayn [35]

Answer:

The mass ratio of oxygen rounded to the nearest whole no. 3 : 2

Explanation:

According to Law of Multiple proportion when two elements combine to make two or more different compounds, the mass ratio of the two element in the first compound, when divided by the mass ratio of the second compound , form a simple whole number ratio.

Compound A contains 1.34 g of sulfur for every 0.86 g of oxygen

$\frac{1.34}{0.86}= 1.5$

Compound B contains 11.63 g of sulfur for every 10.49 g of oxygen

$\frac{11.643}{10.49}= 1.0$

Ratio of oxygen in each compound

always put the larger number over the smaller number.

$\frac{CompoundA}{Compound B}=\frac{1.5}{1.0}=\frac{3}{2}$

What distinguishes compounds from mixtures?

dexar [7]

Answer:

There's a very small difference between the two...a compound is when you mix several elements to create a whole new one. A mixture is when you mix several elements together, but instead of it creating a completely different compound, it's simply just a few elements mixed together.
