Answer:
a) Ra = 0.517 Ω
Rb = 0.032 Ω
Rc = 0.129 Ω
b) Ia = 5.8A
Ib = 93.75A
Ic = 23.2 A
Explanation:
a) The resistance is equal to:
Resistance for case a:

Where
p = 1.5x10⁻²Ωm
L0 = 5.8 cm = 0.058 m

Resistance for case b:

Resistance for case c:

b) The current is equal to:
Current for case a:

Current for case b:

Current for case c:

False I think
Hope this helped ^^;
Answer:
The additional trials needed is 48 trials
Explanation:
Given;
initial number of trials, n = 16 trials
the standard deviation, σ = 0.24 s
initial standard error, ε = 0.06 s
The standard error is given by;

To reduce the standard error to 0.03 s, let the additional number of trials = x

Therefore, the additional trials needed is 48 trials.
Answer:
wave front
Explanation:
wave front is an imaginary line of a wave that joins all adjacent points that are in phase,
so that's the definition, and you apply it to the question
it obviously can't be the rest
hope you get it
please mark it brainliest
