Answer:
670.956
Explanation:
You can use this equation to solve for heat :
Q = m * c * ΔT
Q represents the heat
m represents the mass in kilograms
c is the specific heat. For aluminum, it's 897
ΔT is the change in temperature, so, 49 - 15 which is 34
Plug in the numbers and you get this :
Q = 0.022 * 897 * 34
Q = 670.956 Joules
Answer:
36.8 g/mol of O
Explanation:
To find the number of grams, multiply the number of moles by the atomic mass of the element.
Oxygen has an atomic mass of 16.00.
2.3 moles O × (16.00 g O ÷ 1 mole) = 36.8 g/mol O
Hope that helps.
The average speed of the horse for the entire motion is 66.67 m/s.
The given parameters;
- <em>distance traveled by the horse, d = 1 km = 1,000 m</em>
- <em>time of motion of the horse, t = 15 s</em>
The average speed of the horse is calculated by dividing the total distance traveled by the horse by the time of motion.
The average speed of the horse is calculated as follows;
Thus, the average speed of the horse for the entire motion is 66.67 m/s.
