Answer:
Capacitive reactance of the capacitor is 68 ohms
Explanation:
It is given that,
Capacitance, 
Frequency, 
Capacitive reactance is given by :
or
So, the capacitive reactance of the capacitor is 68 ohms. Hence, this is the required solution.
Answer:
The third stage of parturition is called " after-birth".
Explanation:
Answer: The hypotenuse is 26 ft.
Step-by-step explanation: Let's call the shorter leg of the triangle x. The hypotenuse would be x + 16 and the other leg is y.
As the area is 120, we know that x.y/2 = 120 (because it's a right triangle).
This way, y = 240/x
we know that in a right triangle, we have a² = b² + c²
(x + 16)² = x² + y²
(x + 16)² = x² + (240/2)²
x² + 32x + 256 = x² + 57600/x²
32x + 256 = 57600/x²
32x³ + 256x² = 57600 (÷ 32)
x³ + 8x² = 1800
x = 10
∴
x + 16 = 26
y = 240/10 = 24
Answer:
Part a)
T = 3.96 s
Part b)
T = 1.98 s
Part c)
T = 2.8 s
Explanation:
As we know that time period of spring block system is given as
T = 2.8 s
Part a)
If the mass of the block attached is doubled
then we will have
Part b)
If the spring constant is doubled
then we have
Part c)
If the amplitude is halved but mass and spring constant will remain the same
so here we know that time period does not depends on Amplitude
so we will have
T = 2.8 s
Answer:
Either smaller than or equal to
Explanation:
The shortest path covered by an object is called displacement of a particle while the overall path covered by it during entire journey is called distance covered by it.
In this case, an object goes from one point in space to another. After it arrives at its destination, its displacement is either smaller than or equal to the distance traveled. As distance covered is the overall path, so the displacement is less than distance traveled.
So, the correct option is 4 (either smaller than or equal to). Hence, this is the required solution.
