At the beach in San Francisco (0 meters) the pressure of the atmosphere is 101.325 kPa

Korvikt [17]

Answer:

$P = -\frac{17978}{1609344}(h)+101.325$

Explanation:

Given

$h = height$

$P = Pressure$

$(h_1,P_1) = (0,101.325)$

$(h_2,P_2) = (1609.344 ,83.437 )$

Required

Determine the linear equation for P in terms of h

First, we calculate the slope/rate (m);

The following formula is used:

$m = \frac{P_2 - P_1}{h_2 - h_1}$

Substitute values for P's and h's

$m = \frac{83.347 - 101.325}{1609.344- 0}$

$m = \frac{-17.978}{1609.344}$

$m = -\frac{17.978}{1609.344}$

Multiply by 1000/1000

$m = -\frac{17.978 * 1000}{1609.344*1000}$

$m = -\frac{17978}{1609344}$

The equation is then calculated using:

$P - P_1 = m(h - h_1)$

Substitute values for m, h1 and P1

$P - P_1 = m(h - h_1)$

$P - 101.325 = -\frac{17978}{1609344}(h - 0)$

$P - 101.325 = -\frac{17978}{1609344}(h)$

Make P the subject

$P = -\frac{17978}{1609344}(h)+101.325$

<em>The above is the required linear equation</em>

If a = 2.0 cm, b = 5.0 cm, and i = 20 a, what is the magnitude of the magnetic field at the point p?

attashe74 [19]

If a = 2.0 cm, b = 5.0 cm, and i = 20 a, 6.0 μt is the magnitude of the magnetic field at the point p, So the correct option is (a).

The magnetic influence on moving electric charges, electric currents, and magnetic materials is described by a magnetic field, which is a vector field. A force perpendicular to the charge's own velocity and the magnetic field acts on it when the charge is travelling through a magnetic field.

$B_{1}$ = μ $_{0}$ i $\frac{\pi }{6}$ / $4\pi (a+b)$

$B_{2}$ = μ $_{0}$ i $\frac{\pi }{6}$ / $4\pi b$

As, $B_{1}$ is moving down and $B_{2}$ is moving up so,

$B_{2}$ - $B_{1}$ = (μ $_{0}$ i $\frac{\pi }{6}$ / $4\pi b$ ) - [μ $_{0}$ i $\frac{\pi }{6}$ / $4\pi (a+b)$ ]

$B_{2}$ - $B_{1}$ = μ $_{0}$ i 24 / $(\frac{1}{b} - \frac{1}{a+b} )$

$B_{2}$ - $B_{1}$ = $\frac{4\pi *10^{-7}*20 }{24} (\frac{1}{0.05} -\frac{1}{0.02})$

$B_{2}$ - $B_{1}$ = 5.98× $10^{-6}$ T ≈ 6μT

Therefore, 6.0 μt is the magnitude of the magnetic field .

Which circuit has the largest equivalent resistance?.

Alexeev081 [22]

The series circuit has the higher equivalent resistance, but to find the larger equivalent resistance you have to use Ohm's law (V2=I2R2), the power dissipated by the resistor can also be found using P2=I22R2=V22R2. To find the equivalent resistance of the circuit, notice that the parallel connection of R2 and R3 is in series with R1, so the equivalent resistance is Req=R1+(1R2+1R3)−1=1.00Ω+(16.00Ω+113.00Ω)−1=5.10Ω.

What does the big bang theory suggest

Alika [10]

Answer:

The Big Bang Theory is the leading explanation about how the universe began. At its simplest, it says the universe as we know it started with a small singularity, then inflated over the next 13.8 billion years to the cosmos that we know today.
