Answer:
decantation, distilling, freezing
Explanation:
Given that,
Weight of the friend, W = 600 N
When the friend sits on the metal frame it bends downward 4 cm, we can say that the compression in the it is 4 cm or 0.04 m
To find,
Spring constant for this chair or k
Solve :
The weight of an object is equal to the force exerted by the gravitational force, F = 600 N
According to Hooke's law, the force exerted by the spring is given by :
F = kx
k is the spring constant


k = 15000 N/m
Therefore, the spring constant of the spring is 15000 N/m.
The magnitude of the electric field on the master charge is 1.008 x 10¹⁰ N/C, and the force on the test charge is 5.04 x 10⁹ N.
<h3>Electric field on the master charge</h3>
E = kq/r²
where;
- q is magnitude of master charge
- r is distance of separation
- k is Coulomb's constant
E = (9 x 10⁹ x 0.63)/(0.75²)
E = 1.008 x 10¹⁰ N/C
<h3>Force on the test charge</h3>
F = Eq
where;
- E is electric field
- q is the test charge
F = (1.008 x 10¹⁰) x (0.5)
F = 5.04 x 10⁹ N
Thus, the magnitude of the electric field on the master charge is 1.008 x 10¹⁰ N/C, and the force on the test charge is 5.04 x 10⁹ N.

The plate that is covering most of the two continents
is the Eurasian plate.
The continents are
<span><span>
1. </span><span> Europe</span></span>
<span><span>
2. </span><span> Asia</span></span>
The Eurasian plate is a tectonic plate that amasses
the whole continent of what others call as “Eruasia”.
It takes part of the oceanic crust that starts from
the Mid-Atlantic Ridge and extends itself to northward of the Gakkel Ridge. The
size of this plate is for about 67,800,000 km according to statistics and
geography.
