Explanation:
Given that,
Fencing to be done, P = 400 m
Area of the rectangular garden,
Let l is the length and b is the breadth of the garden. The area of the rectangle is given by :
............(1)
The perimeter of the garden is given by :
...............(2)
On solving equation (1) and (2), we get the value of l and b are as follows :
l = 90 m and b = 110 m
or
b = 90 m and l = 110 m
So, the dimension of the garden is 90 m by 110 m. Hence, this is the required solution.
Answer:
Explanation:
We must use conservation of linear momentum before and after the collision,
Before the collision we have:
where these are the masses are initial velocities of both players.
After the collision we have:
since they clong together, acting as one body.
This means we have:
Or:
Which for our values is:
Answer:
The weight on the neutron star is 99.69 × N.
Explanation:
Here,
weight on earth is 665 N. We can calculate the mass as :
= mg
or, 665= m × 9.810
∴ m = = 67.68 kg
Now weight of this mass on the surface of neutron star:
=
=
= 99.69 × N
The required weight is 99.69 × N.
