Sedbober [7]

Answer:

Displacement from the starting position is 1224m

Explanation:

The object is moving at 120 meters per second, it does this for 10.2 seconds. Use multiplication to find the answer.

$120 \times 10.2 = 1224$

The inductor in the RLC tuning circuit of an AM radio has a value of 250 mHmH . You may want to review (Pages 857 - 860) . Part

ANEK [815]

Answer:

The value of variable capacitor is $1.89 \times 10^{-13}$ F

Explanation:

Given :

Inductance $L = 250 \times 10^{-3}$ H

Frequency $f = 731 \times 10^{3}$ Hz

According to the cutoff frequency,

$f = \frac{1}{2\pi \sqrt{LC} }$

Now we find the value of capacitance,

$C = \frac{1}{4\pi ^{2} f^{2} L }$

$C = \frac{1}{4\times 9.85 \times (731 \times 10^{3} )^{2} \times 250 \times 10^{-3} }$

$C = 1.89 \times 10^{-13}$ F

Therefore, the value of variable capacitor is $1.89 \times 10^{-13}$ F

If you had a 14 m long timeline, where would the extinction of the dinosaurs be?

Lapatulllka [165]

If you had a 14 m long timeline, the dinosaurs would be less than one meter from the end.

<h3>What is extinction of species?</h3>

The extinction of species or organisms is the process by which some environmental factors cause a decline in the number of species through death.

Dinosaurs are some of the examples of species that are in extinct.

Since dinosaurs are in extinction, If you had a 14 m long timeline, the dinosaurs would be less than one meter from the end.
