Explanation:
Given that,
Capacitor 
Resistor 
Peak voltage = 5.10 V
(A). We need to calculate the crossover frequency
Using formula of frequency
Where, R = resistor
C = capacitor
Put the value into the formula
(B). We need to calculate the 
when 
Using formula of
Put the value into the formula
(C). We need to calculate the when 
Using formula of
(D). We need to calculate the when 
Using formula of
Hence, This is the required solution.
Answer:
Natural selection is a simple mechanism that causes populations of living things to change over time. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success.
<span>We can use an equation to find the gravitational force exerted on the HST.
F = GMm / r^2
G is the gravitational constant
M is the mass of the Earth
m is the mass of the HST
r is the distance to the center of the Earth
This force F provides the centripetal force for the HST to move in a circle. The equation we use for circular motion is:
F = mv^2 / r
m is the mass of the HST
v is the tangential speed
r is the distance to the center of the Earth
Now we can equate these two equations to find v.
mv^2 / r = GMm / r^2
v^2 = GM / r
v = sqrt{GM / r }
v = sqrt{(6.67 x 10^{-11})(5.97 x 10^{24}) / 6,949,000 m}
v = 7570 m/s which is equal to 7.570 km/s
HST's tangential speed is 7570 m/s or 7.570 km/s</span>
Answer:
this has to do with the drop in voltage, or potential as electrons traverse the material .
The correct answer is
<span>
B. As speed of a fluid increases, the pressure within decreases.
Using formulas, Bernoulli's principle can be written as
</span>
where p is the pressure of the fluid,
its density, v its speed, and h its elevation above a reference level.
Assuming h does not change, we can see that if the speed v increases, the pressure p must decrease in order to keep constant the sum of the three terms.
