Answer:The sun produces energy through nuclear fusion.

Explanation:

The sun produces energy through nuclear fusion. The sun is a large ball of hydrogen and helium undergoing constant nuclear fusion, in which atoms of hydrogen combine to form helium and release a large quantity of energy. The enormous pressure in the sun keeps the fusion running for huge amounts of time.

What is the equivalent resistance of the circuit?

Sonbull [250]

Answer:

80Ω

Explanation:

Resistance in a series circuit (when one resistor is after another in the same line) is calculated with the following equation

Total resistance = R1 + R2 + R3...Rn

Substitute in your values and solve for total resistance

Total resistance = 60 + 20 = 80Ω

serious [3.7K]

Answer:

The answer to your question is:

a) t = 3.81 s

b) vf = 37.4 m/s

Explanation:

Data

height = 71.3 m = 234 feet

t = 0 m/s

vf = ?

vo = 0 m/s

Formula

h = vot + 1/2gt²

vf = vo + gt

Process

a)

h = vot + 1/2gt²

71.3 = 0t + 1/2(9.81)t²

2(71.3) = 9,81t²

t² = 2(71.3)/9.81

t² = 14.53

t = 3.81 s

b)

vf = 0 + (9.81)(3.81)

vf = 37.4 m/s

marissa [1.9K]

Answer:

$1.65\times {-3} \text { s}$

Explanation:

Current is the rate of flow of charge.

$I=\dfrac{Q}{t}$

$t = \dfrac{Q}{I}$

$t = \dfrac{30.0}{18.2\times10^3} =1.65\times {0-3} = 1.65\times {-3} \text { s}$

A pendulum on earth swings with angular frequency ω. On an unknown planet, it swings with angular frequency ω/ 4. The accelerati

Afina-wow [57]

Answer:

g / 16

Explanation:

T = 2π $\sqrt{\frac{l}{g} }$

angular frequency ω = 2π /T

= $\sqrt{\frac{g}{l} }$

ω₁ /ω₂ = $\sqrt{\frac{g_1}{g_2} }$

Putting the values

ω₁ = ω , ω₂ = ω / 4

ω₁ /ω₂ = 4

4 = $\sqrt{\frac{g}{g_2} }$

g₂ = g / 16

option d is correct.
