Complete question :
Xavier is roller skating at 14 km/h and tosses a set of keys forward on the ground at 8 km/h. The speed of the keys relative to the ground is km/h.
Answer:
22 km/hr
Explanation:
Speed of keys with respect to ground ; V(k - g)
Speed of keys with respect to skater ; V(k - s)
Speed of skater with respect to ground ; V(s - g)
V(s - g) = 8 km/hr
V(k - s) = 14 km/hr
Substituting the values into the equation :
V(k - g) = V(s - g) + V(k - s)
V(k - g) = 8km/hr + 14km/hr
V(k - g) = 22 km/hr
Smart Metering is a technology encouraging end-use energy efficiency. Smart Meters can give consumers clear and comprehensive information about their energy consumption and, giving them better information, can help consumers to become more energy efficient.

Explanation:
Answer:
Cp = 0.142 [cal/g*°C].
Explanation:
In order to solve this problem, we must use the following equation of thermal energy.
where:
Q = heat energy = 60 [cal]
Cp = specific heat [cal/g*°C]
T_final = final temperature = 10[°C]
T_initial = initial temperature =40[°C]
m = mass of the substance = 14 [g]
