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:
y=(3/8)x+5.75
Step-by-step explanation:
y=mx+b
m=slope
b=y-intercept
m=(8-5)/(6+2)=3/8
y=mx+b
5=3/8(-2)+b
5=-3/4+b
b=5.75
y=mx+b
y=(3/8)x+5.75
Answer: 3
Step-by-step explanation:
the statement given us:
7a-5b+4
a= 2
b= 3
so we have:
7*(2)-5*(3)+4
14-15+4 = 3
the answer is 3
9514 1404 393
Answer:
14.14
Step-by-step explanation:
The diagonal of a square is √2 times the side length.
AC = AB×√2
AC = 10√2 ≈ 14.14
_____
The diagonal of a square is the hypotenuse of an isosceles right triangle. If the sides of that are s and the diagonal is d, the Pythagorean theorem tells us ...
d² = s² + s²
d² = 2s²
d = (√2)(√s²) = s√2
This relation holds for <em>any isosceles right triangle</em>, not just for the diagonal of this square. It is useful to remember.
Answer:
65 yd
Step-by-step explanation:
The diagonal of a rectangle can be found using
Pythagoras' Theorem a² + b² = c²
(where a and b are the legs, and c is the hypotenuse of a right triangle)
Given:
⇒ 25² + 60² = c²
⇒ c² = 4225
⇒ c = √4225
⇒ c = 65
Therefore, the length of the diagonal is 65 yd
