Answer:
Poisson’s ratio = 0.36
Explanation:
Given that
Diameter ,d= 10 mm
Force ,F= 15000 N
Reduction in diameter ,Δd = -7 x 10⁻³ mm
E= 100 GPa
Longitudinal strain
Lateral strain
μ= 0.36
Poisson’s ratio = 0.36
Answer:
Minimum electrical power required = 3.784 Watts
Minimum battery size needed = 3.03 Amp-hr
Explanation:
Temperature of the beverages,
Outside temperature,
rate of insulation,
To get the minimum electrical power required, use the relation below:
V = 5 V
Power = IV
If the cooler is supposed to work for 4 hours, t = 4 hours
Minimum battery size needed = 3.03 Amp-hr
By increasing magnification you decrease the field of view.
The answer is A.
Hope this helps.
