Answer : (C) refraction.

Explanation :

This figure shows the refraction of light. Refraction of light is the phenomena in which light rays bend at the boundary of two medium.

When a light ray moves from denser to rarer medium then it will bend away from the normal line.

And if it moves from rarer to denser medium then it will bend toward the normal line.

Refraction of light depends on the refractive index of the medium.

So, the correct option is (C) "refraction"

Where do you find cations on the periodic table

saw5 [17]

Answer:

Explanation:

The electronic configuration of many ions is that if a closes noble gas to them in a periodic table.

An Anion is a ion that has gained one or more electron, acquiring a negative charge.

A Cation is a ion that has lost one or more electron, gaining a positive charge.

In a physics lab experiment, a compressed spring launches a 24 g metal ball at a 35o angle above the horizontal. Compressing the

Levart [38]

Answer:

k = 45.95 N/m

Explanation:

First, we will find the launch speed of the ball by using the formula for the horizontal range of the projectile.

$R = \frac{v_{o}^{2}\ Sin\ 2\theta}{g} \\\\v_{o}^{2} = \frac{Rg}{Sin\ 2\theta}\\$

where,

Vo = Launch Speed = ?

R = Horizontal Range = 5.3 m

θ = Launch Angle = 35°

Therefore,

$v_{o}^{2} = \frac{(5.3\ m)(9.81\ m/s^{2})}{Sin\ 2(35^{o})}\\$

v₀² = 55.33 m²/s²

Now, we know that the kinetic energy gain of ball is equal to the potential energy stored by spring:

$Kinetic\ Energy\ Gained\ By\ Ball = Elastic\ Potential\ Energy\ Stored\ in \ Spring\\\frac{1}{2}mv_{o}^{2} = \frac{1}{2}kx^{2}\\\\k = \frac{mv_{o}^{2}}{x^2} \\$

where,

k = spring constant = ?

x = compression = 17 cm = 0.17 m

m = mass of ball = 24 g = 0.024 kg

Therefore,

$k = \frac{(0.024\ kg)(55.33\ m^2/s^2)}{(0.17\ m)^2} \\$

Define Plateau period.

Amiraneli [1.4K]

A plateau period refers to a period in life where you are kind of stuck in the middle. There is little growth or decline so you are kind of at a standstill.
