Periodic waves spread out over the surface of a lake where two women, Jenny and Melissa, are fishing in separate boats 46 meters

apart. Each woman's boat bobs up and down 26/min. At a time when Jenny's boat is at a crest, Melissa's boat is at its lowest point, and there are 4 additional crests between them. Calculate the wavelength of these water waves.

Answer:

The wavelength of the water is \lambda = 10.22 m

Explanation:

From the question awe are told that

                The distance between the two boats are 46 m

   Now we are told that a the time the Jenny's boat is at a crest,Melissa's boat is at its lowest point, and there are 4 additional crests between them which can be mathematically represented as

                         Number of wavelength = 4 + 0.5(this accounts for the difference in position crest and lowest point)

                                                              = 4.5

Now the wavelength of the water is \lambda = \frac{Distance }{Number \ of \ division }

                                                                 = \frac{46}{4.5} =10.22m

Which describes an object in projectile motion? Check all that apply.A.Gravity acts to pull the object downB.The object moves in
irina1246 [14]

Answer:

A.Gravity acts to pull the object down

D.The object’s inertia carries it forward.

E.The path of the object is curved.

Explanation:

The motion of a projectile consists of two independent motions:

- A uniform motion along the horizontal direction, with constant horizontal speed

- A vertical motion with constant acceleration of g = 9.8 m/s^2 downward (acceleration due to gravity), due to the presence of the force of gravity, so the vertical velocity changes (increases in the downward direction)

As a result, the combined motion of the projectile has a curved trajectory (parabolic, more specifically). So the following options are correct:

A.Gravity acts to pull the object down --> gravity acts along the vertical direction

D.The object’s inertia carries it forward. --> there are no forces acting along the horizontal direction (if we neglect air resistance), so the horizontal motion continues with constant speed

E.The path of the object is curved
