Why is a pencil bent when bent in water

Physics
1 answer:
wel3 years ago
5 0

Answer:

Refraction

Explanation:

A pencil bends when it enters the water media due to the phenomenon of refraction.

  • Refraction is one of the properties of waves.
  • Refraction of light occurs which it crosses from a region having different density values.
  • Water is denser than air.
  • As light moves from air to wave it becomes refracted

An electron, tial well may be anywhere within the interval 2a. So the uncertainty in its position is Δx= 2a. There must be a co
lapo4ka [179]

Answer:

      K =  \frac{h'}{8 m  \ \Delta x^2}K

Explanation:

The Heisenberg uncertainty principle is

          Δx Δp ≥ h' / 2

          h’ =\frac{h}{2\pi }

The kinetic energy of a particle is

          K = ½ m v²

           p = mv

           v = \frac{p}{m}

substitute

           K = \frac{1}{2}  \frac{p^2}{m}

from the uncertainty principle,

           Δp = \frac{h'}{2 \ \Delta x}

we substitute

          K = \frac{1}{2m} ( \frac{h'}{2 \ \Delta x})^2

          K =  \frac{h'}{8 m  \ \Delta x^2}

What is the source of geothermal energy? User: What is the source of geothermal energy?
bazaltina [42]

The answer is; C

In particular points in the earth’s surface, underground water is naturally heated to steam that can be harness for geothermal energy. The steam that ejects from the ground with high kinetic energy can be used to turn turbines that generate electricity. The underground water is usually heated by the hot rocks beneath that are subjected to the immense heat of magma or the enormous pressure of overlying crust.

Is it possible to have motion in the absence of a net force?
Vsevolod [243]

Answer:

It is impossible...

Explanation:

Under no circumstances this is possible because of the Newton’s 1st law of motion that states that a body shall continue its motion forever except the net fore is zero. When two opposing forces contract each other, they cancel out the action of each other and ultimately the net force become zero. If one body has a slightly more or less force then the net force will not be zero and the net magnitude of force will have a direction of motion.

A rock weighs 110 N in air and has a volume of 0.00337 m3 . What is its apparent weight when submerged in water? The acceleratio
pickupchik [31]

Explanation:

It is given that,

Weight of the rock in air, W = 110 N

Since, W = mg

m=\dfrac{W}{g}

m=\dfrac{110\ N}{9.8\ m/s^2}

m = 11.22 kg

We need to find the apparent weight of the rock when it is submerged in water. Apparent weight is equal to the weight of liquid displaced i.e.

M=d\times V

d is the density of water, d=1000\ kg/m^3

V is the volume of rock, V=0.00337\ m^3

M=1000\ kg/m^3\times 0.00337\ m^3

M = 3.37 kg

The apparent weight in water, W = m - M

W=7.85\ kg\times 9.8\ m/s^2

W = 76.93 N

So, the apparent weight of the rock is 76.93 N. Hence, this is the required solution.
