After the body has begun shivering, what explains why it would stop shivering?
Oksana_A [137]
The body shivers to produce energy and it uses the energy to keep it warm. The body would stop shivering when it has produced enough energy to keep it warm and the atmosphere around it has got warmer

Asteroids, meteoroids, and comets are remnants of the early solar system. (T/F)
4vir4ik [10]

Answer: Asteroids, meteoroids, and comets are remnants of the early solar system. This Statement is TRUE.

Explanation:

METEOROID: these are small rocky or metallic objects found in outer space.

ASTEROIDS: these are also known as minor planets of the inner solar system. They are irregularly shaped object in space that orbits the Sun.

COMETS: these are dusty chunk of ice, that moves in a highly elliptical orbit about the sun.

Asteroids, meteoroids, and comets as remnants of the early solar system was further proved in nebular hypothesis

initially proposed in the eighteenth century by German philosopher Immanuel Kant and French mathematician Pierre-Simon Laplace. (The word nebula means a gaseous cloud.) According to the modern version of the theory, about 4.5 to 5 billion years ago the solar system developed out of a huge cloud of gases and dust floating through space. These materials were at first very thin and highly dispersed.

The critical angle for a liquid in air is 520, What is the liquid's index of refraction? 0.62 0.79 1.27 1.50
sammy [17]

Answer:

Liquid's index of refraction, n₁ = 1.27

Explanation:

It is given that,

The critical angle for a liquid in air is, \theta_c=52^o

We have to find the refractive index of the liquid. Critical angle of a liquid is defined as the angle of incidence in denser medium for which the angle of refraction is 90°.

Using Snell's law as :

n_1sin\theta_c=n_2sin\theta_2

Here, \theta_2=90

sin\theta_c=\dfrac{n_2}{n_1}

Where

n₂ = Refractive index of air = 1

n₁ = refractive index of liquid

So,

n_1=\dfrac{n_2}{sin\theta_c}

n_1=\dfrac{1}{sin(52)}

n₁ = 1.269

or n₁ = 1.27

Hence, the refractive index of liquid is 1.27
