Suggest one reason why the 1990 coin might have a lower mass than the new one.?
One reason the 1990 coin could have a lower mass than the new one is if the composition of the new coin includes heavier metals or alloys. This change in composition could have been made to increase the durability or security features of the coin.
Why does a old coin have a lower mass than a new one?
The mass of an old coin may be lower than that of a new coin due to wear and tear over time, which can result in some material being rubbed off or lost. Additionally, dirt, oils, and other contaminants that accumulate on the surface of the coin can contribute to the overall decrease in mass.
Why might a 1990 coin have higher mass than a new one?
The difference in mass between a 1990 coin and a new one is negligible for all practical purposes, unless the currency has been redesigned. (For example, in the early 1990's the UK issued new 5p and 10p coins to replace much heavier old coins.)
Is coin a mass noun?
No, the noun 'coin' is a countnoun, the plural form is coins (one coin, six coins).
Why are some objects heavier than others?
Objects are heavier than others due to differences in their mass and density. Mass is the amount of matter in an object, while density is how compact that matter is. Objects with higher mass or higher density will be heavier than those with lower mass or lower density.

Which property of a coin is different on the moon than it is on earth?
Mass
What has a lower atomic mass cobalt or nickel?
Interestingly, nickel has a lower atomic mass (58.693) than cobalt (58.933), even though cobalt has a lower atomic number (27) than nickel (28).

What was health like in 1990?
The obicitey rate was lower than it is now.

Why does venus have lower gravity than earth?
Venus has lower gravity than Earth because it has a smaller mass than Earth. Gravity is directly proportional to the mass of a planet, so planets with smaller masses will have lower gravitational forces.
Why would old coins have a lower mass than new ones?
Many countries have changed their coin compositions over the years. The reasons can be due to metal changes, size changes, etc. Another reason is that circulation will wear down a coin, so that an older specimen actually has slightly less metal on it than when it was new.
Which has the lower atomic mass cobalt or nickel?
Cobalt has an atomic mass of 58.933195(5) while nickel has an atomic mass of 58.6934(4). Nickel has the lower atomic mass.
Which has a lower atomic mass lead or cobalt?
Cobalt has a lower atomic mass than lead. The atomic mass of cobalt is approximately 58.93 g/mol, whereas the atomic mass of lead is about 207.2 g/mol.
