We are given the total volume of liquid equal to 3392.92 cubic inches and a total of 30 glass spheres to be poured in. In this case, we divide the volume by 30 equal to 113.0973 cubic inches. The formula of the volume of a sphere is 4/3 pi r^3. r then is equal to 3 inches in which the diameter should be 6 inches.
Answer: elastic (e = 2.43)
Explanation:
The price elasticity formulae is given below as
Elasticy of price = change in quantity demanded / change in price.
P1 =$2.60, P2 = $6.30, q1 =17 and q2 = 8
e = q2 - q1/ P2 - P1
e = 8 - 17/ 6.30 - 2.60
e = - 9 /3.7
e = - 2.43
We take the modulus of e to have a positive value. Hence e = 2.43
Since e is greater than 1, then the elasticity of demand is elastic
No, because the energy is the capacity for performing work. Gravity is the force that draws everything to the earth's center.
Answer:
1) 2726.5 J/K 2) decrease 3) 0
Explanation:
1)
change in entropy is given by
here Q=mL where L is the latent heat of vaporization. therefore
2)
since the heat is taken from surroundings, the change in entropy is negative therefore entropy of surrounding will decrease.
3) since there is no heat exchange with universe therefore , Q=0 in this case
