Two objects a and b of same masses and velocities v and 3v respectively are in motion . which object of larger momentum

the object with velocity 3v has larger momentum

Explanation:

Momentum= P = m v

P = momentum

m= mass

V= velocity

for first object, P1 = mv

for second object , P2 = m (3v)

P2= 3 mv

so the momentum of second object is three times the momentum of the first object.

c.the charges if the proton and electron and gravity

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
