Answer:

gravity

Explanation:

Gravity is a force of attraction that exists between any two masses, any two bodies, any two particles. Gravity is not just the attraction between objects and the Earth. It is an attraction that exists between all objects, everywhere in the universe. ... where G is called the Gravitational Constant.

Answer:

Force of gravity

Explanation:

The force that attracts masses, bodies, particles, objects to one another is what is referred to as force of gravity. This description describes gravity as the attraction between objects and the earth.

But that's not all what gravity is all about.

Gravity also refer to the attraction that exists between all objects, everywhere in the universe.

When the only force that applies on a body is the force of gravity (for example object in free fall), the acceleration of that body is acceleration due to gravity; this is represented by g and it's equivalent to 9.8m/s² on earth.

One thing to note is that, all objects (regardless of their mass) have the same acceleration when in a state of free fall.

Answer:

shadow length 7.67 cm

Explanation:

given data:

refractive index of water is 1.33

by snell's law we have

$n_{air} sin30 =n_{water} sin\theta$

$1*0.5 = 1.33*sin\theta$

solving for $\theta$

$sin\theta = \frac{3}{8}$

$\theta = sin^{-1}\frac{3}{8}$

$\theta = 22 degree$

from shadow- stick traingle

$tan(90-\theta) = cot\theta = \frac{h}{s}$

$s = \frac{h}{cot\theta} = h tan\theta$

s = 19tan22 = 7.67 cm

s = shadow length

Why do earthquakes and volcanoes occur along continent and ocean boundaries?

jeyben [28]

Earths plates move, creating them to rub together to create earthquakes, and volcanoes occur because magma melts rocks and the pressure is so intense it causes the lava to leak out of the top of a mountain
