Answer:
50 N/m
Explanation:
When a spring is stretched by a force, the relationship between the force applied and the stretching of hte spring is
where
F is the force applied
k is the spring constant
x is the stretching of the spring
In this problem, we have:
F = 5.0 N is the force applied to the spring
x = 10 cm = 0.10 m is the stretching caused by the force
Solving for k, we find:
Answer:
41.053 A
Explanation:
given,
three phase kVA = 25-kVA
voltage = 440 Volt
current = ?
To determine three phase kVA when volts and amperes are know
three phase kVA = 1.73 x V x I
I = 32.84 A
the maximum overcurrent protection value is equal to
= 125 % of I
= 1.25 x 32.84
= 41.053 A
Answer:
h = 3.1 cm
Explanation:
Given that,
The volume of a oil drop, V = 10 m
Radius, r = 10 m
We need to find the thickness of the film. The film is in the form of a cylinder whose volume is as follows :
So, the thickness of the film is equal to 3.1 cm.
