The 45-g Wood Thrush migrates every spring from Central America to the United States to breed. The bird leaves its winter home in Belize and travels 1422 km across the Gulf of Mexico to Louisiana. It then flies an additional 1343 km to reach
Virginia, where it spends the summer. The trip takes approximately 171 hours, flying mostly at night.
What is the average speed of the Wood Thrush?

v = 16.16 km/h

Explanation:

Distance covered by Wood Thrush is 1422 km across the Gulf of Mexico to Louisiana + 1343 km to reach  Virginia, where it spends the summer.

d = 1422 km + 1343 km

d = 2765 km

The trip takes approximately 171 hours, flying mostly at night, t = 171 hours

We need to find the average speed of the Wood Thrush. It can be given by :

So, the average speed of the Wood Thrush is 16.16 km/h.

the answer is c.)

explanation:

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
