Answer:
0.87 m
70.6 Hz
Explanation:
= length of the rope = 1.30 m
= order of the harmonic = 3
= Wavelength
Wavelength is given as
= 0.87 m
= Speed of transverse wave = 61.4 m/s
= frequency of the third harmonic
frequency is given as
= 70.6 Hz
Answer:
The current in the primary is 0.026 A
Explanation:
Using the formula
I1 = (V1/V2)*I2
we have
I1 = (6.4/120)*0.500
I1 = 0.026 A
Answer:
Self-motivation is the surest way to stay focused. Nearly all the most significant tasks in life are tests for our motivation. Facing challenges and achieving success requires focus; this means we need to be responsible for our motivation. People who are motivated towards achieving their goals are focused on success.

Explanation:
The old sweet potatoes rootlings
The acceleration is given as:
a = g sin(30°) where g is the gravitational acceleration
For g = 10 m/s^2, we get
a = 10 sin(30°) = 10 * 1/2 = 5 m/s^2
