Answer:
Mass is proportional to gravity and gravity is necessary to hold an atmosphere, therefore mass would seem to be very important for the ability for a body to have an atmosphere. However there are quite a few examples that show that it doesn't require that much mass to get an atmosphere.
Explanation:
Im pretty sure its called a tendon. :/
Answer:
The index refraction of the unknown material is 1.08
Explanation:
Light has characteristics of a wave. When light travels or propagates through two media with different index of refraction, the light will bend or will change its speed.
Using Snells' law which is stated mathematically as:
n1Sintheta1 = n2Sinthetha2
Given:
n1 = 1.17
Theta1 = 40.1° = angle of incidence
Theta2 = 36.3° = angle of refraction
n2 = unknown
Substituting into the equation
n1Sin40.1 = 1.17Sin36.3°
0.6441n1 = 0.6937
n1 = 0.6937/0.6441
n1 = 1.08
Answer:
Mass of object is 0.5kg
Explanation:
Given the following data;
Force = 6N
Acceleration = 12m/s²
Mass =?
Force is given by the multiplication of mass and acceleration.
Mathematically, Force is;
Where;
F represents force.
m represents the mass of an object.
a represents acceleration.
Making mass (m) the subject, we have;
Substituting into the equation;
Mass, m = 0.5kg.
Therefore, the mass of the object is 0.5kg
Answer:
When something is heated, its atoms vibrate. If one end of a metal bar is heated, the atoms at that end vibrate more than the atoms at the cold end. The vibration spreads along the bar from atom to atom. ... Metals are good conductors of heat.
