The data not given here is the specific heat capacity of pyrex glass equal to 0.75(J/g °C). In this case, heat is equal to mass x specific heat capacity x temperature rise. Temperature difference is then equal to 1910 J / 0.75 J/g °C / 23 g equal to 110. 75 <span>°C </span>

<em>this cow be doing that viurtua</em>Explanation:

d = total displacement of the person running due east = 15 km
t = time taken by the person to travel the given distance due east = 2.0 hr
v = average velocity of the person in east direction = ?
average velocity is the ratio of total displacement to total time taken. hence
average velocity = total displacement/total time
v = d/t
inserting the values
v = 15 km/2.0 hr
v = 7.50 km/hr
Answer: D. 0.5
Explanation:
The slope formula is y2-y1/x2-x1.
2-(-1)/4-(-2) = 2+1/4+2
2+1/4+2 = 3/6 = 1/2
1/2 = 0.5
The slope is 1/2, or 0.5.
