Coquina rock is deposited on the water bodies of the Earth's surface and oceans.
<u>Explanation:</u>
Coquina is nothing but a type of sedimentary rock generally limestone that is formed by the chunks of shells, trilobites, brachiopods, or other invertebrates.
Coquina is deposited on the oceans and water bodies of the Earth's surface. Coquina looks like a soft white rock; therefore it can be used in construction of buildings.

See below
Explanation:
Vertical position = 45 + 20 sin (30) t - 4.9 t^2
when it hits ground this = 0
0 = -4.9t^2 + 20 sin (30 ) t + 45
0 = -4.9t^2 + 10 t +45 = 0 solve for t =4.22 sec
max height is at t= - b/2a = 10/9.8 =1.02
use this value of 't' in the equation to calculate max height = 50.1 m
it has 4.22 - 1.02 to free fall = 3.2 seconds free fall
v = at = 9.81 * 3.2 = 31.39 m/s VERTICAL
it will <u>also</u> still have horizontal velocity = 20 cos 30 = 17.32 m/s
total velocity will be sqrt ( 31.39^2 + 17.32^2) = 35.85 m/s
Horizontal range = 20 cos 30 * t = 20 * cos 30 * 4.22 = 73.1 m
'First Quarter' is the phase that appears one quarter of the
period of time from one new moon to the next one.
The total period of the moon's phases is 29.53 days (rounded).
One quarter of it is (29.53 / 4) = <em>7 days 9.2 hours</em> (rounded)
Answer:
A charged object in an electric field experiences a force due to the field. The electric field strength, E, at a point in the field is defined as the force per unit charge on a positive test charge placed at that point.
Explanation:
V=IR. This is the formula that you can use to figure this question out. Because the voltage stays the same and the current decreases, this means that the resistance has increased.
