In 1909, galileo first looked at the milky way using very powerful binoculars

anastassius [24]

<span>Galileo first studied the Milky Way through his telescope in January, 1610 not 1909. Until his observations, the Milky Way was thought to be a band of wispy whitish clouds passing through the heavens. To Galileo's amazement, instead of seeing just a nebula (the Greek work for cloud) the milky wisps resolved into innumerable tiny stars, so crowded together that, without the aid of a telescope, the light from those stars simply blended together. </span>

A series RLC circuit is driven by a 1.0-kHz oscillator. The circuit parameters are Vms = 12 V, L = 5.0 mH, C= 4.0 uF, and R=102.

alexgriva [62]

Answer:

C) $12.3$ volts

Explanation:

f = frequency of oscillator = 1 kHz = 1000 Hz

$V_{rms}$ = 12 Volts

L = Inductance of Inductor = 5 mH = 0.005 H

$X_{L}$ = Inductive reactance

Inductive reactance is given as

$X_{L}$ = $2\pi fL$

$X_{L}$ = $2(3.14) (1000)(0.005)$

$X_{L} = 31.4$

$X_{C}$ = Capacitive reactance

Capacitive reactance is given as

$X_{C}=\frac{1}{2\pi fC}$

$X_{C}=\frac{1}{2(3.14)(1000)(4\times 10^{-6})}$

$X_{C} = 39.8$

Impedance of the circuit is given as

$z = \sqrt{R^{2}+(X_{L} - X_{C})^{2}}$

$z = \sqrt{102^{2}+(31.4 - 39.8)^{2}}$

$z = 102.35$

Rms Current flowing is given as

$i = \frac{V_{rms}}{z}$

$i = \frac{12}{102.35}$

$i = 0.12$ A

Rms potential difference across the resistor is given as

$V = i R$

$V = (0.12) (102)$

$V = 12.3$ volts

One person is in a pool and is diving to a depth of 2.3m, and another person is diving to a depth of 3m. What pressure does each

Vlad [161]

Explanation:

The static pressure is P = ρgh, where ρ is the density of the fluid and h is the depth.

For the first person:

P = (1000 kg/m³) (9.8 m/s²) (2.3 m)

P = 22,500 Pa

For the second person:

P = (1000 kg/m³) (9.8 m/s²) (3 m)

P = 29,400 Pa

Suppose you place an object 8 cm in front of a converging lens and the image appears 16 cm on the other side of the lens. What i

Marianna [84]

Answer:

5.33 cm

Explanation:

The lens equation states that:

$\frac{1}{f}=\frac{1}{p}+\frac{1}{q}$

where

f is the focal length

p is the distance of the object from the lens

q is the distance of the image from the lens

In this problem,

p = 8 cm

q = 16 cm ( the sign is positive since the image is real, which means it is formed on the other side of the lens)

Substituting into the equation,

$\frac{1}{f}=\frac{1}{8 cm}+\frac{1}{16 cm}=\frac{3}{16 cm}$

$f=\frac{16}{3}cm=5.33 cm$
