Answer: A) 30 grams

Explanation: According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants.

mass of reactants= mass of antacid + mass of water= 30 g+ 50 g= 80 g

Given : Mass of product = 50 g

But mass of products should be equal to mass of reactants = 80 g

Thus mass of another product= (80-50)g = 30 g.

Two identical speakers are emitting a constant tone that has a wavelength of 0.50 m. Speaker A is located to the left of speaker
Marianna [84]

Answer:

a) and c).

Explanation:

For a complete destructive interference occur, it must be met the following condition relating the wavelength, and the difference in the paths taken by the sound emitted by the sources until arriving to the listening point:

d = |dA- dB| = (2n-1)*(λ/2)

For n= 1,  d = λ/2 = 0.25 m, it doesn't meet any of the cases.

For n=2, d= 3*(λ/2) = 0.75 m

In the case a) we have dA = 2.15 m and dB = 3.00 m, so dB-dA = 0.75 m, which means that in the location stated by case a) a complete destructive interference would occur.

For n=3, d= 5*(λ/2) = 5*0.25 m = 1.25 m.

This is just the case c) because we have dA = 3.75 m and dB = 2.50 m, so dA-dB = 1.25 m, which means that in the location stated by case c) a complete destructive interference would occur also.

The remaining cases don't meet the condition stated above, so the statements found to be true are a) and c),

In a recent year, wind machines in a country generated 183.1 billion kWh of electricity, enough to serve over 17 million househo
Neko [114]

Answer:

The right answer is "4.4%".

Explanation:

Given:

Generated electricity,

= 183.1 billion kWh

Total electricity production,

= 4098 billion kWh

Now,

The wind energy percentage will be:

= \frac{183.1}{4098}\times 100

= 0.0446\times 100

= 4.4 %
