Answer:
Kinetic energy and potential energy.
Explanation:
Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v^2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared. Kinetic energy is usually measured in units of Joules (J); one Joule is equal to 1 kg m^2 / s^2.
The formula for potential energy depends on the force acting on the two objects. For the gravitational force, the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m/s^2 at the surface of the earth) and h is the height in meters. Notice that gravitational potential energy has the same units as kinetic energy, kg m^2/s^2. In fact, all energy has the same units, kg m^2/s^2, and is measured using the unit Joule (J).
Work is also measured with the unit Joule (J).
Answer:
Radiation , Conduction and Convection
Explanation:
Those are the ways heat is transferred
Answer: The particles of a solid are [generally] closest together while those of a gas are farthest apart
Explanation:
Answer:
The wavelength is 
Explanation:
From the question we are told that
The thickness is 
The refractive index of the non-reflective coating is 
The refractive index of glass is 
Generally the condition for destructive interference is mathematically represented as
Where 
is the angle of refraction which is 0° when the light is strongly transmitted
and n is the order maximum interference
so
at the point n = 1
at n =2
Now we know that the wavelength range of visible light is between
So the wavelength of visible light that is been transmitted is
Answer:
v=30 m/s
Explanation:
h - height
g - acceleration due to gravity=10
t - time
v- velocity
45 = 5t²
t² = 9
t=3 seconds
v=g×t
v=10×3
v=30 m/s
