1 BTU mean 1 degree of F increased for 1 pound mass. Since the mass unit is in kg that means you need to convert it into pound. One metric ton means 1000kg and 1 kg mean 2.20462lb, then the water mass is: 1000kg x 2.20462lb/kg= 2204.62lb.
You are putting 110,000 btus of heat, so the calculation would be
Temperature increase= energy/mass = 110000btus/ 2204.62lb= 49.9 degree
The average speed is a scalar quantity. The average speed of the skier is 10 km/hrs.
<h3>
What is the average speed?</h3>
It is calculated by dividing the total distance by the total time elapsed.
The

Where,
= average velocity
= displacement = 7.5 km
= change in time = 45 min = 0.75 hours
Put the values in the formula,

Therefore, the average speed of the skier is 10 km/hrs.

Absorption:
<span>If the wavelength of the light happens to match the distance between two electron levels in the material, it can be absorbed. Light disappears and its energy becomes part of the heat energy of the material. </span>
<span>Metals have so many free electrons that all wavelengths are absorbed -- they are opaque to xrays, visible light, radio waves, everything. </span>
<span>Pigments have specific electron gaps that absorb only the light of a specific wavelength, which we see as color </span>
<span>Transparent materials do not happen to have any gaps between electron levels that match any of the wavelengths of visible light. </span>
|V| = 10.33 units and the direction θ = -47.35° or 312.65°.
Given the x and y components of a vector, we can calculate the magnitude and direction from these components.
Applying the Pythagorean theorem we have that the magnitude of the vector is:
|V| = 
|V| = 
The expression for the direction of a vector comes from the definition of the tangent of an angle:
tan θ =
------> θ = arc tan 
θ = arc tan 
θ = -47.35° or 312.65°
