Answer:
Energy stored, E = 0.072 J
Explanation:
Given that,
Capacitance, 
Capacitance, 
These two capacitor are connected in parallel, and charged to a potential difference of, V = 60 volts
We know that in parallel combination of capacitor, the equivalent capacitance is given by :
The energy stored in the capacitor is given by :
So, the energy stored in the capacitor in this capacitor combination is 0.072 J.
If she walks 132 and 6 you do 132 x 6 = 792
Answer:
H = 1/2 g t^2 where t is time to fall a height H
H = 1/8 g T^2 where T is total time in air (2 t = T)
R = V T cos θ horizontal range
3/4 g T^2 = V T cos θ 6 H = R given in problem
cos θ = 3 g T / (4 V) (I)
Now t = V sin θ / g time for projectile to fall from max height
T = 2 V sin θ / g
T / V = 2 sin θ / g
cos θ = 3 g / 4 (T / V) from (I)
cos θ = 3 g / 4 * 2 sin V / g = 6 / 4 sin θ
tan θ = 2/3
θ = 33.7 deg
As a check- let V = 100 m/s
Vx = 100 cos 33.7 = 83,2
Vy = 100 sin 33,7 = 55.5
T = 2 * 55.5 / 9.8 = 11.3 sec
H = 1/2 * 9.8 * (11.3 / 2)^2 = 156
R = 83.2 * 11.3 = 932
R / H = 932 / 156 = 5.97 6 within rounding
Answer:
The vacuum tube was replaced with transistor.
Explanation:
- The invention of semiconductor was very useful in making solid state transistor that allowed the production of small yet faster, cheaper, and more trusted and reliable computers.
- These solid state transistor is so often used that, it nearly replaced all the use of transistor.
- This replacement took place after the invention of semiconductor in the year around 1940.
- Vacuum tubes also known as thermionic tubes are not used anymore in computers and electronics.
Melatonin is a hormone being produced by small gland in the brain called pineal
gland that helps control sleep and wake cycles. It is also called the sleep
hormone because it gives signal that it’s time to sleep. People
also used this hormone to adjust the body’s internal clock. It is the hormone
that released in response to exposure to sunlight. When the sun sets and night
falls, the pineal is activated and begins to vigorously produce melatonin. The
amount of melatonin tends to rise as night falls, peaks at midnight, and falls
again as the sun rises. It means that it produced more when darker and when the
lighter it is; the less melatonin is produced.
