Question 16 options: If the speed of an object is increasing, then the forces acting on that object must be .

speed

Explanation:

.

An object accelerates when its speed changes or its direction of motion changes or both. ... If the forces pushing or pulling on an object are not balanced (a net force acts) then the object will accelerate in the direction of the net force.

Explanation:

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary 

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
