They share covalent bonds
Answer:
a) According to Newton's law of gravitation, as the distance between the Moon and the Earth decreases, the gravitational attraction increases and vice versa
The gravitational force of the Moon on the Earth causes the Earth to be slightly bulged on the side directly facing the Moon
The gravitational force also pulls the water bodies on the Earth's surface towards the Moon in the same manner and the effect is more pronounced due to the ability of the liquid water to assume a shape based on the magnitude of the gravitational field attracting it
Therefore, the region where the Moon is closest to the Earth we have a high tide as the water level rises and the region which is perpendicular to where the Moon is located has a low tide
b) The two special types of tides are
1) The neap tide
2) The spring tide
Neap tide
Neap tide occurs when the Sun and Moon are 90° apart from each other when they are viewed by an observer from Earth
The gravitational pull of the Sun cancels (partially) the effect of the gravitational pull and tidal force of the Moon, resulting in minimum tidal range
Spring Tide
Spring tide occurs when the Earth, the Moon, and the Sun are simultaneously inline, such that the Sun reinforces the gravitational pull and tidal force of the Moon, resulting in a maximum tidal range

Answer: certificate authority
Explanation: The user submits Identification data and certificate request to the registration authority (RA). The RA validates this information and sends the certificate request to the certificate Authority (CA)
Answer:
The answer to your question is: c
Explanation:
a) The car stops moving. The statement is true because fromthe interval 5 to 10 s, the car does not move.
b) The car changes direction. This statement is true because from 0 to 5 seconds, the vehicle is moving away from the origin and from 10 to 12.5 is getting closer to the origin.
c) The speed of the car is constant during the trip. This sentence is wrong because from 0 to 5 is moving with one velocity and from 10 to 12.5 is moving with a different velocity.
d) The car returns to the starting point of the trip. This sentence is correct, the movement starts at displacement equals to zero and ends at the same displacement.
<span>The total mass that should be placed in the right cap so
that the caps equilibrate at equal height is also 1 kg. if equilibrium should
be maintained the force in each side should cancel out, so to balance a 1kg
mass, a 1 kg mass should also be place on the opposite direction</span>
