Its science number 6 to 10

Hey there!

As per questions,

☆ A feather and a coin fall at the same time, which statement is correct?

Ans:- The feather will meet greater air resistance

☆ What is the weight of a 5-kilogram baby in Newton (N)?

Ans:- 49 N

Steps - As 1 kg = 9.8 N, so 5kg baby = 5×9.8 => 49 N

☆ The force that Earth exerts on any object is

Ans:- attraction

☆ Two objects move toward each other because of gravitational attraction. As the objects get closer and closer, the force between them

Ans:- increases

☆ Suppose the gravitational force between two masses is 10 N. If the distance between the masses is cut in half, what is the force between the masses?

Ans:- 40N

Steps- Gravitational force is 10N

Distance is cut in half

Now using the formula,

As you see the distance between the masses is the denominator squared.

This means that if we reduce the distance by half, then the force will increase by a multiple of .

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
