The thermal energy of an object is the energy contained in the motion and vibration of its molecules. Thermal energy is measured through temperature. The energy contained in the small motions of the object's molecules can be broken up into a combination of microscopic kinetic energy and potential energy.
Answer:
The Speed Of The Lightwave Will Be Modified As It Enters Another Medium (State Of Matter)
Explanation:
As The Lightwave Enters The Medium The Light Will Bend Toward The Normal E.g. Incident Ray Which Indicates It Will Modify It's Speed But When it Leaves The Medium It Will Increase Until As It Leaves The Sold
Answer:
w = 0.808 rad / s
Explanation:
As indicated by the moment of inertia t the angular velocity of the disks we use the concept of conservation of the angular momentum, for this we define the system as formed by the two discs, therefore the torque during the crash is internal and the angular momentum is conserved
Let's write in angular momentum
Initial. Before impact
L₀ = I₁ w₁ + I₂ w₂
Final. After the rock has stuck
= (I₁ + I₂) w
The two discs are rotating in opposite directions, we consider the rotation of the first positive disc, so the angular velocity of the second is negative
L₀ =
I₁ w₁ - I₂ w₂ = (I₁ + I₂) w
w = (I₁ w₁ - I₂ w₂) / (I₁ + I₂)
Let's calculate
w = (0.47 2.0 - 0.31 1.0) / (0.47+ 0.31)
w = 0.63 / 0.78
w = 0.808 rad / s
in the direction of disc rotation 1
1 is b high birth rate and death rate 2 is a low birth rates death are constant and 3 is c high birth rate and low death rate
Explanation:
