A hot air balloon rises in the first place because the air inside is hot, which rises. So, if the air inside is not heated, it fails to rise and falls. Warm air rises because the particles get excited and jiggle with the heat, and cause the air to take up more space. So, as the surrounding air is probably colder and denser, the less dense hot air rises up in the hot air balloon.
Answer:
0.34 s
Explanation:
Given that,
Initial speed of a ball, u = 5.8 m/s
It is kicked at an angle of 17.0° above the horizontal.
The vertical component of velocity will be,
Let it takes t time in the air before it lands on the ground again. It can calculated as :
So, it will take 0.34 seconds.
The smallest size capacitor is the "01005" chip (electrolytic) capacitor with a dimension of only 0.4 mm × 0.2 mm. Electrolytic capacitors have a high capacitance because there is a very thin oxide layer between the anode and cathode, which can be about 1 nm.
Capacitance, a property of an electric conductor or set of conductors that is measured by the amount of separate electric charge that can be stored on it per unit change in electric potential.
C = Q / V
Where,
Q denotes the charge of the conductor,
V denotes the potential applied across the conductor and
C is proportionality constant, called capacitance
Two most important factors are:
- Larger plate area results in more field flux (charge collected on the plates)
- Closer spacing results in a greater field force, which results in a greater field flux.
