<h3>
Answer:</h3>
24.94 L
<h3>
Explanation:</h3>
<u>We are given;</u>
- Moles of Helium, n= 1 mole
- Pressure of the gas, P = 100 kPa
- Temperature of the gas, T = 300 K
We are required to calculate the volume of the balloon
- We are going to use the ideal gas equation;
- According to the ideal gas equation;
PV = nRT , where R is the ideal gas constant, 8.314 L.kPa/mol.K
V = nRT ÷ P
= ( 1 × 8.314 × 300 K) ÷ 100 kPa
= 24.94 L
Therefore, the volume of the balloon is 24.94 L

Answer:
Explanation:
A rectifier is an electrical device that converts alternating current (AC) to direct current (DC), a process known as rectification. Rectifiers have many uses including as components of power supplies and as amplitude modulation detectors (envelope detectors) of radio signals. Rectifiers are most commonly made using solid state diodes but other type of components can be used when very high voltages or currents are involved. When only a single diode is used to rectify AC (by blocking the negative or positive portion of the waveform), the difference between the term diode and the term rectifier is simply one of usage. The term rectifier describes a diode that is being used to convert AC to DC. Most rectifier circuits contain a number of diodes in a specific arrangement to more efficiently convert AC power to DC power than is possible with only a single diode.
It is overhead at the equator, it is because the sun ray’s
will be moving vertically as this will be directed at the equator. It is
because if it moves vertically, it will hit or overhead the equator and this
usually happens in spring and fall.
