Physics Questions

Many types of renewable energy resources such as wind and solar energy are constantly replenished and will never run out.

coulomb is unit of Electric Charge,

watt per meter per degree celcius is unit of Thermal Conductivity,

joule per kilogram per Kelvin is unit of Specific Heat capacity.

General purpose gloves - utility gloves are recommended for cleaning procedures, such as handling soiled linens or decontaminating care areas. Utility gloves are more tear and puncture resistant than other gloves.

1st copper wire: R = pl/A = pl/ πr2

2ndcopper wire: R’ = p’l’/A’ = pl/(4 πr2) = R/4

If joined in parallel, (1/Req) = (1/R) + (1/R’)

= 1/R + 4/R1/Req= 5/R

Req= R/5

Magma is injected into surrounding rock forming an igneous intrusive.

Actually it is a plutonic formation in which magma present beneath Earth surface deforms the shape of rocks present above it
 

This orbital velocity at the moon is less because orbital velocity = rg

where 'r ' is the orbital radius. i.e the distance of the body from the center of the earth and 'g' is the acceleration due to gravity on the body in question. In the case of the moon, both r and g are less than in the case of the earth.
