What material would make the best light bulb filament?
a. a conductor surrounded by an insulator.
b. a resistor, which converts some electric energy to light and thermal energy.
c. an insulator, which stops the flow of electricity.
d. a conductor, which carries electric currents.

A resistor, which converts some electric energy to light and thermal energy.

Explanation:

A bulb filament is made of resistor which allows the current to pass. Usually the metal- Tungsten is used to make the filament. A filament is a wire in the bulb through which current passes and it glows.  Joule heating phenomenon is used. The electrical energy is converted to heat and light energy by the resistor when current passes through it.

Tungsten has a very high melting point, it is hard and high thermal stability. Thus, it makes the best bulb filament.

get the total number of pieces of fruit and divide it by 4 to get the average. the result is the answer to the problem. 14 total number of fruits and there are 4 members. 14 divided by 4 is equals to 3.5.

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
