Answer:

The minimum quantity of steam required per pound of ice is -22.5 BTU/lbm

Explanation:

Q = mCT

Q/m = CT

Q/m is the quantity of steam required per pound of ice

C is the heat capacity of ice = 0.45 BTU/lbm°F

T is the temperature of ice = -50 °F

Q/m = 0.45 BTU/lbm°F × -50 °F = -22.5 BTU/lbm

Explain the difference between SI base units and SI delivered units
castortr0y [4]

SI Units are based on meters, kilograms, seconds, amperes, kelvins, candelas, and moles, together with a set of prefixes to indicate multiplication or division by a power of ten.

There are seven SI base units, which are:

m - Meter - Length.

s - Second - Time.

mol/Mole - Amount of Substance.

A - Ampere - Electric Current.

K - Kelvin - Temperature.

cd - Candela - Luminous Intensity.

kg - Kilogram - Mass.

I think that the delivered units are how they are used such as watts which are equal to one joule per second. Others are “ergs per second (erg/s), horsepower (hp), metric horsepower (Pferdestärke (PS) or cheval vapeur (CV)), and foot-pounds per minute.”

So, SI base units are the basic units of things such as length or temperature. This would mean that the delivered units are the specific units per something like miles per hour.

Why don’t we feel the gravitational pull of objects around us?
spayn [35]
It is because gravity is not an independent force. Gravity comes as result of warped space time according to the theory of general relativity. Therefore we can’t feel gravity because it’s not a force that pulls or pushes.

Two identical cars are driving in opposite directions at the same speed. their kinetic energies have ____.
Minchanka [31]
The equation for determining the kinetic energy of the system is,

      KE = 0.5mv²

where m is the mass, v is velocity and KE is the kinetic energy. When both objects have the same mass, and velocity but different direction, they will have the same kinetic energy. 

This is because the exponent in the velocity is squared cancelling out the effect of the sign appearing before the number.
