Answer:
a) 
b) 
Explanation:
Given:
- mass of the body,
- mass of the tyre,
- length of hanging of tyre,
- distance run by the body,
- acceleration of the body,
(a)
Using the equation of motion :
..............................(1)
where:
v=final velocity of the body
u=initial velocity of the body
here, since the body starts from rest state:
putting the values in eq. (1)
Now, the momentum of the body just before the jump onto the tyre will be:
Now using the conservation on momentum, the momentum just before climbing on the tyre will be equal to the momentum just after climbing on it.
(b)
Now, from the case of a swinging pendulum we know that the kinetic energy which is maximum at the vertical position of the pendulum gets completely converted into the potential energy at the maximum height.
So,
above the normal hanging position.
Answer:
1. Count the atoms of each element in the reactants and the products.
2. Use coefficients; place them in front of the compounds as needed.

Answer:
a)
b)
Explanation:
The gravitational force on the satellite is calculated with Newton's Gravitation Law:
Where 
is Earth's mass, 
is the satellite mass, 
is the distance between their centers, where 
is the height of the satellite (from Earth's surface) and 
is Earth's radius, and 
is the gravitational constant.
a) With these values we then have:
b) And the fraction this force is of the satellite’s weight <em>W=mg</em> is:
Explanation:
alike
no contact with the object itself
they can attract objects
they're between 2 objects
difference
source of foundations
type of forces
gravity is only for huge objects
<span>So when the charged insulator is placed near the uncharged metallic thing they both attract each other because there will be a distribution of charge between the insulator and uncharged object. This migration of charges happens regardless of their charge positive or negative.</span>
