What is the force needed to lift a 65kg box?

637N

Explanation:

Force needed to lift box = ?

Mass of box = 65kg

Acceleration due to gravity, g = 9.8m/s2

Recall that Force applied depends on the mass of an object moved against gravity.

Thus, Force = Mass x acceleration due to gravity

F = mg

F = 65kg x 9.8m/s2

F = 637N

Thus, 637 newton of force is needed to lift a 65kg box

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

pretty sure it's false
