If you take a boat from earth and put it on a planet with twice earth’s gravity, what would
happen if you tried to float it in water? Hint: Think about the buoyancy force formula. (5
points)
2. You drop a cube of mass 1 kg into a cup of water. It sinks with an acceleration of 2
m/s^2.
a. What is the buoyancy force of the water? (4 points)
b. What is the density of the water if the volume of the cube is 30 cm^3 (4 points)

On this “Living Planet” that we call Earth, there are lots of
interesting events that take place. These events are around us,
which we see or do or experience regularly. At some point in time,
your curiosity would have pushed you to ask questions about what’s
going on? How does that happen? Well, leaving miracles apart, the
answer to all these questions is “Physics.” In fact, Physics
governs our everyday lives in one way or the other. A camera is...

The most efficient way to send a spacecraft from the earth to
another planet is by using a Hohmann transfer orbit (the
figure (Figure 1)). If the orbits of the departure and destination
planets are circular, the Hohmann transfer orbit is an elliptical
orbit whose perihelion and aphelion are tangent to the orbits of
the two planets. The rockets are fired briefly at the departure
planet to put the spacecraft into the transfer orbit; the
spacecraft then coasts until it...

You are on a planet where the moon's orbit is approximately 9
weeks (i.e. twice the period of earth's moon), but the distance to
the moon is also twice as much. The mass of the planet is ____
times that of earth.

A spaceship travels at a constant speed from earth to a planet
orbiting another star. When the spacecraft arrives, 11 years have
elapsed on earth, and 9.7 years have elapsed on board the ship. How
far away (in meters) is the planet, according to observers on
earth?

On a planet far far away from Earth, IQ of the ruling species is
normally distributed with a mean of 103 and a standard deviation of
17. Suppose one individual is randomly chosen. Let X = IQ of an
individual.
a. What is the distribution of X? X ~ N(,)

over 85. Round your answer to 4 decimal
places.
