What is the value of R2 in this parallel circuit? (5 stars)
o-na [289]

Answer:

20 Ω

Explanation:

Voltage, current, and resistance are related by Ohm's law:

V = IR

40 V = (4 A) R

R = 10 Ω

The total resistance of the circuit is 10 Ω.

Resistors in parallel have a total resistance of:

1/R = 1/R₁ + 1/R₂

1 / (10 Ω) = 1 / (20 Ω) + 1/R₂

R₂ = 20 Ω

Tsunamis are fast-moving waves often generated by underwater earthquakes. In the deep ocean their amplitude is barely noticable,
Charra [1.4K]

To develop this problem it is necessary to apply the concepts related to the kinematic equations of motion. And from the speed found the relationships between wavelength, frequency and last of the period (which is inversely proportional to the frequency)

PART A) We know that the velocity of a body or a wave is equivalent to the distance traveled over a time interval. So,

V = \frac{x}{t}

Where

x = Distance

t = time

V = \frac{3650*10^{3}}{4.59h(\frac{3600s}{1h})}

V = 215.44m/s

PART B) The frequency would then be defined as

f = \frac{V}{\lambda}

Where

\lambda = Wavelength

f = \frac{215.44}{732*10^{3}}

f = 2.943*10^{-4}Hz

PART C) Finally the period is defined as

T = \frac{1}{f}

T = \frac{1}{2.943*10^{-4}}

T = \frac{1}{2.943*10^{-4}}

T = 3397.89s
