Answer:

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 :

So, the specific heat of the material is
.
Answer:
1400 miles
Step-by-step explanation:
Speed is the time rate of change of distance. It is the ratio of distance to time and is given by the equation:

plane averaged 400 mph on a trip going east, but only 280 mph on the return trip.
The time spent (t₁) in going east is given by:

The time spent (t₂) in going east is given by:

The total time (t) = t₁ + t₂
t = t₁ + t₂ = 8.5 hours

Therefore the one way distance is 1400 miles

Math
Answer:
Where the width is W feet long, the area of the rectangle in terms of a polynomial
= 3W² - 2W
Step-by-step explanation:
The area of a rectangle is the product of the length and the width of the rectangle. Given that a rectangle has a Length L feet and a width W feet, the area A
= L * W
If the length of a rectangle is two feet less than three times the width.then
L = 3W - 2
The area A
= (3W - 2) * W
= 3W² - 2W
