Answer:

Magnification is the degree to which an object is multiplyed to get it's image.

For example if an object size is 10cm an it's image size is 20cm then the magnification is 2, that is the image is twice the size of the object.

Hope that helps

Coquina is a sedimentary rock you looked at in the lab that consists of tiny chunks of sea shells all stuck together by other mi

HACTEHA [7]

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.

if a ball is released from a height 80cm how long would it take the ball to reach the ground when g= 10m per seconds

VLD [36.1K]

Answer:

The ball took 0.4 seconds

Explanation:

» From the second newton's equation of motion.

${ \boxed{ \tt{s = ut + \frac{1}{2} {gt}^{2} }}}$

s is displacement, s = 80cm, s = 0.8 meters
u is initial velocity, u = 0 [ from rest ]
g is 10 m/s²

${ \tt{0.8 = (0 \times t) + ( \frac{1}{2} \times 10 \times {t}^{2} )}} \\ \\ { \tt{0.8 = 5 {t}^{2} }} \\ { \tt{ {t}^{2} = 0.16 }} \\ { \tt{t = \sqrt{0.16} }} \\ \\ { \underline{ \underline{ \tt{ \: time = 0.4 \: seconds \: \: }}}}$

For resistors in series, the equivalent resistance is _____ of their values.

Stels [109]

Answer: The correct answer is "the same as the sum".

Explanation:

The expression for the equivalent resistance in the series combination of the circuit is as follows;

$R'=R_{1} +R_{2} +R_{3}$

Here, R' is the equivalent resistance, $R_{1},R_{2},R_{3}$ are the resistances.

The expression for the equivalent resistance in the parallel combination of the circuit is as follows;

$\frac{1}{R'} =\frac{1}{R_{1}} +\frac{1}{R_{2}}+\frac{1}{R_{3}}$

Here, R' is the equivalent resistance, $R_{1},R_{2},R_{3}$ are the resistances.

In the series combination of the circuit, the equivalent resistance is more than the equivalent resistance in the parallel combination of the circuit.

In the series combination of the circuit, the same amount of current flows across the resistance but the voltage is different across the resistances.

Therefore, for resistor in series, the equivalent resistance is the same as the sum.
