Answer:
the total kinetic and potential energy of its particles
Explanation:
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.
<em>The y-intercept of a position-time graph of an object gives the average velocity of the object is False.</em>
<u>Answer:</u> <em>False.
</em>
<u>Explanation:</u>
The initial position of the object can be obtained by calculating the Y intercept of a position-time graph. In a position-time graph, the independent variable is time and dependent variable is position. Y axis is the position axis and x axis is the time axis.
The equation of the graph is given by . m is the slope of the graph and c is the y intercept. When a particle starts from the origin its y intercept is zero.
The nature of the graph gives us an idea about velocity. When the velocity is positive, the position- time graph has positive slope and when the velocity is positive the graph has negative slope.
Answer:
w = 0.319 rad / s
Explanation:
This is an angular momentum problem, let's form a system composed of the feeder and the squirrel, therefore the forces during the collision are internal and the angular momentum is conserved.
initial instant. Before the squirrel jumps
L₀ = m v r
final instant. After the trough and the squirrel are together
L_f = (I_fetter + I_ardilla) w
angular momentum is conserved
L₀ = L_f
m v r = (I_fetter + I_ardilla) w
w =
the moment inercial ofbody is
I_thed = 2.00 kg m²
We approach the squirrel to a specific mass
I_ardilla = m r²
we substitute
w = m v r / ( I_[feefer + m r²)
let's calculate
w = 3 3.40 6.30 10⁻² / (2.00 + 3.00 (6.30 10-2)² )
w = 0.6426 / 2.0119
w = 0.319 rad / s
Answer:
lasing threshold condition is 32.78 cm
Explanation:
given data
uncoated facets R = 0.32
a = 10 cm
length L = 500 um = m
to find out
lasing threshold condition
solution
we know lasing threshold condition formula that is
lasing threshold = a - ln ..........1
put here all value in equation 1 we get
lasing threshold = a - ln
lasing threshold = 10 - ln
lasing threshold = 32.78
so lasing threshold condition is 32.78 cm
