. . . 'protect' its domestic steel industry, by
increasing the price of imported steel.
Answer: One quarter of the force
Explanation:
According to Newton's law of Gravitation, the force exerted between two bodies of masses and and separated by a distance is equal to the product of their masses and inversely proportional to the square of the distance:
(1)
Where is the gravitational constant
This means that the gravity force decreases when the distance between these two bodies increases.
In this context, if the distance between the capsule and the Earth increases twice, the new distance will be .
Substituting this distance in (1):
(2)
<u>Finally:</u>
>>>This means the force toward Earth becomes one quarter "weaker"
Answer:
The unit of power is pascal.
(D)
Explanation:
This kind of bond where the electrons are transferred is called ionic bond. This bond occurs between a metallic and non-metallic elements. The other kind of bond (covalent) involves the sharing of electrons and this happens between non-metallic elements.
