The resistance and the magnitude of the current depend on the path that the current takes. The drawing shows three situations in

mihalych1998 [28]

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:

$R_{a} =\frac{pL_{a} }{A_{a} } =\frac{p*4*L_{0} }{2L_{0}*L_{0} } =\frac{2p}{L_{0} }$

Where

p = 1.5x10⁻²Ωm

L0 = 5.8 cm = 0.058 m

$R_{a} =\frac{2*1.5x10^{-2} }{0.058} =0.517ohm$

Resistance for case b:

$R_{b} =\frac{pL_{b} }{A_{b} } =\frac{pL_{0}}{2L_{0}4L_{0} } =\frac{p}{8L_{0}} =\frac{1.5x10^{-2} }{8*0.058} =0.032ohm$

Resistance for case c:

$R_{c} =\frac{pL_{c}}{A_{c} } =\frac{p2L_{0}}{L_{0}4L_{0}} =\frac{p}{2L_{0}} =\frac{1.5x10^{-2} }{2*0.058} =0.129ohm$

b) The current is equal to:

Current for case a:

$I_{a} =\frac{V}{R_{a} } =\frac{3}{0.517} =5.8A$

Current for case b:

$I_{b} =\frac{V}{R_{b} } =\frac{3}{0.032} =93.75A$

Current for case c:

$I_{c} =\frac{V}{R_{c} } =\frac{3}{0.129} =23.2A$

The period of a pendulum is measured 16 times. The average value of the period over these 16 trials is calculated to be 1.50 sec

marin [14]

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;

$\epsilon = \frac{\sigma}{\sqrt{n} }$

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

$0.03= \frac{0.24}{\sqrt{n+x} } \\\\0.03= \frac{0.24}{\sqrt{16+x} }\\\\0.03\sqrt{16+x} = 0.24\\\\\sqrt{16+x} = \frac{0.24}{0.03} \\\\\sqrt{16+x} = 8\\\\16+x = 8^2\\\\16+x = 64\\\\x = 64 -16\\\\x = 48 \ trials$

Therefore, the additional trials needed is 48 trials.

A(n) _______ is a line in which waves move that are moving together all in the same phase

Gekata [30.6K]

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
