Most tennis balls are usually hollow, while golf balls are not. Therefore a golf ball contains more mass.

Hope this helps!

A tennis ball is practically air surrounded by structure to form a ball thus having an almost hollow internal portion. In the case of a golf ball, it is concentrated with the material from the inside out. So even though on average a golf ball would be much smaller than a tennis ball, it would have larger mass because of it concentration of solid to its core while in the case of the tennis ball, most of its space is occupied by air which is lighter than the solid of the golf ball.

morpeh [17]

Answer:

The molar amount of the gas.

Explanation:

If the pressure, volume, and temperature of a gas are known than molar amount can be determine.

Formula:

PV = nRT

P = pressure

V = volume

R = general gas constant

T = temperature

n = number of moles

Example:

V = 2 L, P = 1 atm , T = 273 K , R = 0.0821 atm. L/mol.K

n = PV/RT

n = 1 atm. 2 L / 0.0821 atm. L/mol.K . 273 K

n = 2 / 22.413 /mol

n = 0.09 mol

Magnesium has three stable isotopes. The most commonly occurring isotope, 24 Mg, has an isotopic mass of 23.985 u and makes up 7

aleksandr82 [10.1K]

Answer:

Average atomic mass = 24.3051 amu

Explanation:

Average Atomic Mass = (Mass of Isotope 1 x Fractional Abundance of Isotope 1) + (Mass of Isotope 2 x Fractional Abundance of Isotope 2) + ......

For 24 Mg

Mass = 23.985 amu

Fractional Abundance = 0.7899

Mass * Fractional Abundance = 18.9458

For 25 Mg

Mass = 24.986 amu

Fractional Abundance = 0.10

Mass * Fractional Abundance = 2.4986

For 26 Mg

Mass = 25.983

Fractional Abundance = 0.1101

Mass * Fractional Abundance = 2.8607

Average atomic mass = 24 Mg + 25 Mg + 26 Mg

Average atomic mass = 18.9458 + 2.4986 + 2.8607

Average atomic mass = 24.3051 amu

marta [7]

Answer:

$\huge\boxed{5 \ m/s}$

Explanation:

Given:

Distance = S = 50 m

Time = t = 10 secs

Unknown:

Speed = v = ?

Formula:

v = S/t

Plug In:

S = 50 m , t = 10 secs

Solution:

v = 50 m / 10 secs

v = 5 m/s
