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).
