11-Determine the specific heat of a material if a 12-g sample absorbed 96 J as it was heated from 20°C to 40°C. *

kompoz [17]

Answer:

$c=0.4\ J/g^{\circ} C$

Step-by-step explanation:

Given that,

Mass of a sample, m = 12 g

Heat absobed by the sample, Q = 96 J

It was heated from 20°C to 40°C.

We need to find the specific heat of a material. The heat absorbed by a sample is given by :

$Q=mc\Delta T\\\\c=\dfrac{Q}{m\Delta T}\\\\c=\dfrac{96}{12\times (40-20)}\\\\=0.4\ J/g^{\circ} C$

So, the specific heat of the material is $0.4\ J/g^{\circ} C$ .

Duru has an ice-cream stand, which she opens on days that are forecasted to be warmer than 10°C.

Amanda [17]

Answer:

$P(c(t)) = 20t-120$

Step-by-step explanation:

Given

$P(n) = 2n - 20$

$C(t) = 50 + 10(t - 10)$

Required

Determine $P(C(t))$

The implication of the question is to solve for $P(C(t))$

Given that

$C(t) = 50 + 10(t - 10)$ and $P(n) = 2n - 20$

$P(c(t))$ would be

$P(c(t)) = 2(50 + 10(t - 10)) - 20$

$P(c(t)) = 2(50 + 10t - 100) - 20$

Collect Like Terms

$P(c(t)) = 2(50 - 100+ 10t) - 20$

$P(c(t)) = 2(-50+ 10t) - 20$

Open Bracket

$P(c(t)) = -100+ 20t - 20$

Collect Like Terms

$P(c(t)) = 20t-100 - 20$

$P(c(t)) = 20t-120$
