Answer:
The answer is A.
Explanation:
when the ball gets to R and S then that's when gravity starts to take over instead of kinetic energy so therefore its potential energy
Answer:
Sustancia Masa (g) Composición (% m/m)
<em>Proteínas</em> 5,5 4,4
<em>Azúcares</em> 5,0 4,0
<em>Sodio </em>0,06 0,048
<em>Potasio </em>0,15 0,12
Explanation:
Para calcular la composición porcentual en masa de las sustancias debemos usar la siguiente ecuación:
En donde:
es la masa de la sustancia
es la masa del yogurt = 125 g
Para las proteínas:

The element X is titanium.
According to the question, the percentage by mass of Cl in XCl4 is 75.0%.
The percentage by mass is obtained from;
Mass of element in the compound/molar mass of compound * 100
Hence;
Let the mass of the unknown element be X
75 = 142/X + 142 * 100
75 (X + 142) = 142 * 100
75X + 10650 = 14200
75X = 14200 - 10650
X = 14200 - 10650/75
X = 47
Hence, X is titanium.

Explanation:
A qualitative property of matter is a property characteristic of a substance like color and flavor.
A quantitative property of matter is a property when we get a number.
A) it's a circular shape is a qualitative property because the shape is a qualitative property and shape is not represented by a number.
B) its mass is 1.5 kg is a quantitative property because we know a number of this mass.
C) it tastes like chocolate is a qualitative property because the flavor is characteristic of a substance and flavor is not measured in numbers.
D) it is 30 cm in diameter it is a quantitative property, we know the exact dimension of it.
E) its icing is melting is a qualitative property, melting is a property of ice, it just happens.
