READER’S DIGEST

A WEIGHTY MATTER

The mass of an

object in kilograms (kg)

stays the same no

matter where it is, but its

weight in newtons (N)

changes along with

gravitational conditions.

On Earth, Mari weighs

686 N and has a mass of

70 kg. Her German

shepherd, Chip, weighs

343 N with a mass of 35

kg. On Mars, they each

weigh 38 per cent of

their Earth weight. On

the Moon, they each

weigh 16 per cent of it.

Which one weighs

more: Mari on the Moon

or Chip on Mars?

Bonus: Which one has

the most mass?

CAPITAL IDEA

Below is a list of national capitals as their names are

rendered in official languages of their respective countries

(without accents). There’s a way to enter six of them into

the grid, one per row or column, so that they intersect like

a crossword. They must be entered left to right or top to

bottom, without skipping squares. Each capital city must

intersect with three others. Not every square needs to

have a letter in it. Can you fill in the six cities? One letter

has been placed to get you started.

ANKARA (Turkey); BAMAKO (Mali); BOGOTA (Colombia);

DAKAR (Senegal); HARARE (Zimbabwe); JAKARTA

(Indonesia); KAMPALA (Uganda); LUSAKA (Zambia);

MALABO (Equatorial Guinea); MBABANE (Eswatini);

OTTAWA (Canada); SUVA (Fiji); TARAWA (Kiribati).
