Explanation:
The thermal conductivity of an object is defined as the measure or the ability of the object to transfer heat or conduct heat through its body.
In the context, the thermal conductivity of the material is given as
And it is given that :
1 Btu = 1055 J
1 ft = 0.3048 m
We know that 1 h = 3600 s
So the thermal conductivity of the material in is :
Thermal conductivity :
= 223.25
Answer:
Explanation:
1. =
* cos
⇒ 16*cos32 ≈ 13.6 m/s (13.56)
2. =
* sin
⇒ 16* sin32 ≈ 9.4 m/s
3. =
=
(the g (gravity) depends on the country but i'll take the average g which is 9.2m/s^2)
≈ 3.6677+1.5 ≈ 5.2m
4. =
=
≈ 23.5m (23.47)
5. -
answer 4 could be wrong, not certain about that one and i don't know 5
Answer:
D. 3
Explanation:
First of all the mechanical advantage of a wedge is defined as the ratio of its slope length to its width.
Mathematically,
where,
IMA= Mechanical Advantage
L= slope length, and
w= width.
Given that,
slope length, L= 3.3 inches, and
width ,W= 1.1 inches
Then,
Mechanical Advantage, IMA
