Answer:
45 takes less energy and is less stronger light than a 60 watt bulb, but a 60 watt bulb is stronger and takes more energy.
Explanation:
Answer:
option A
Explanation:
given,
shear force = 425 N
Shear modulus = 1.7 × 10⁹ N/m²
disk equivalent to solid cylinder
height = 0.7 cm and diameter = 6.50 cm
hence, the correct answer is option A
Answer:
<em>The contribution of people to the cooling load of the store is 19722.5 W</em>
Explanation:
Total amount of customers = 225
Total amount of employees = 20
Total amount of people in the store at that instant n = 245 people
Average rate of heat generation Q = 115 W
percentage of these heat generated that is sensible heat = 70%
Sensible heat raises the surrounding temperature. Latent heat only causes a change of state.
The total heat generated by all the people in the store = n x Q
==> 245 x 115 = 28175 W
but only 70% of this heat is sensible heat that raises the temperature of the store, therefore, the contribution of people to the cooling load of the store = 70% of 28175 W
==> 0.7 x 28175 = <em>19722.5 W</em>
Answer: hello the image related to your question is missing attached below is the missing image
answer :
1.47°
Explanation:
First we have to determine the displacement
first : apply law of similar triangles
Scd / 1 = Sef / 3
Fcd ( displacement ) = 3Fef - 80
= 3(30) - 80 = 10 kip
angle of tilt ( θ ) = cos^-1 ( 1 / 10 )
= cos^-1 ( 0.1 ) = 1.47°
attached below is the detailed solution on the displacement value
Answer:
<h2>2500 N</h2>
Explanation:
The weight of the object can be found by using the formula
w is the workdone
d is the distance
From the question we have
We have the final answer as
<h3>2500 N</h3>
Hope this helps you
