The second choice is the correct one.

You can spot it just from the units. An equation can't be true unless it has the same units on both sides.

Wavelength has units of (meters).

Frequency has units of (per second).

When you multiply them, you get (meters per second), the unit of speed, and the 'c' on the other side is speed.

None of the other choices has units of speed on the right side.

You are camping in the breathtaking mountains if Colorado. You spy an unopened diet soda can floating motionless below the surface of a lake. What is the direction and amount of force the water exerts on it?

A. Zero

B. Down, equal to the can's weight

C. Up, equal to the can's weight

D. Not enough information is given

from the principle of flotation which states that a

When a body displaces a weight of water equal to its own weight, it floats. : A floating object displaces a weight of fluid equal to its own weight. ... Archimedes' principle equates the buoyant force to the weight of the fluid displaced.

the upthrust (this is the upward vertical force exerted on an object in fluid)in the water equals the weight of the body in water it floats.
