Electric
current passes through a filament of an incandescent bulb, thereby increasing
it temperature. When current flows, it contains electrons through the filament
to produce light. Typically, incandescent light bulb consists of a glass enclosure
that contains tungsten filament. The glass enclosure contains either a vacuum
or an inert gas that serves as the filament protection from evaporating.
Incandescent light bulbs contain a stem attached at to its base to allow the
electrical contacts to run through the envelope without gas or air leaks.
Answer: B. A model of a cell is easier to manipulate
Explanation: just took the test//APEX
Answer:
3850 J
Explanation:
= initial volume of the gas = 30 L = 0.03 m³
= final volume of the gas = 65 L = 0.065 m³
= Constant pressure of the gas = 110 kPa = 110000 Pa
= Work done by the gas
Since the pressure is constant, Work done by the gas is given as

Answer:
An example of positive velocity is throwing a ball upwards
An example of downward vertical velocity is when an object is dropped, for example a ball dropped from a height
Explanation:
In a vertical movement the acceleration is always downwards, therefore negative since it is created by the attraction of the Earth on the body.

Answer:
Explanation:
The average pressure at mean sea-level (MSL) in the International Standard Atmosphere (ISA) is 1013.25 hPa, or 1 atmosphere (atm), or 29.92 inches of mercury. Pressure (p), mass (m), and the acceleration due to gravity (g), are related by P = F/A = (m*g)/A, where A is surface area.
