Answer:
7 deg
Explanation:
= mass of the rod =
= weight of the rod =
= spring constant for left spring =
= spring constant for right spring =
= stretch in the left spring
= stretch in the right spring
= length of the rod = 0.75 m
= Angle the rod makes with the horizontal
Using equilibrium of force in vertical direction for left spring
Using equilibrium of force in vertical direction for right spring
Angle made with the horizontal is given as
Answer:
Explanation:
Given:
- mass of monkey,
- angle of vine from the vertical,
Now follow the schematic to understand the symmetry and solution via Lami's theorem.
<u>The weight of the monkey will be balanced equally by the tension in both the vines:</u>
Using Lami's Theorem:
Answer:
Therefore,
Current through Nichrome wire is 0.3879 Ampere.
Explanation:
Given:
Length = l = 10 meter
V = 12 Volt
To Find:
Current, I =?
Solution:
Resistance for 0.0-m long 22-gauge nichrome wire with a radius of 0.321 mm if it is connected across a 12.0-V battery given as
Where,
R = Resistance
l = length
A = Area of cross section = πr²
Substituting the values we get
Now by Ohm's Law,
Substituting the values we get
Therefore,
Current through Nichrome wire is 0.3879 Ampere.
