Answer:

46.482 cm

Explanation:

Since 1 in = 2.54cm\\\\18.3 inches =(18.3 x 2.54) cm\\                   =46.482cm

Describe the path of the electric current through a circuit?​
Kruka [31]

Answer:

current moves from positive terminal of a cell towards the negative terminal of a cell.

Explanation:

this happens when good conductors which have free electrons moving randomly within them.when a cell i s connected across the ends the free electrons moves in a given direction. then the current starts flowing in a opposite direction with electrons which moves negative terminal to positive terminal.

A 45.0-kg girl is standing on a 147-kg plank. The plank, originally at rest, is free to slide on a frozen lake, which is a flat,
max2010maxim [7]

Answer:

v_1 = 1.17 m/s

Explanation:

given,

mass of the girl (m₁)= 45 kg

mass of the plank(m₂) = 147 kg

constant velocity of girl relative to plank  = 1.53 m/s

velocity relative to ice berg(v₁) = ?

conservation of momentum

momentum of system = 0

m_1v_1 = m_2v_2

45 \times v_1 = 147 \times (1.53 - v_1)

45v_1 = 224.91 - 147 v_1

192 v_1 = 224.91

v_1 = \dfrac{224.91}{192}

v_1 = 1.17 m/s

hence, the velocity relative to ice berg is 1.17 m/s

If the ball shown in the figure lands in 0.5 s, about what height was it thrown from?
Ede4ka [16]

Answer: 1.22 m

Explanation:

The equation of motion in this situation is:

y=y_{o}+V_{oy}t-\frac{g}{2}t^{2} (1)

Where:

y=0 is the final height of the ball

y_{o}=h is the initial height of the ball

V_{oy}=V_{o}sin(0\°)=0 is the vertical component of the initial velocity (assuming the ball was thrown vertically and there is no horizontal velocity)

t=0.5 s is the time at which the ball lands

g=9.8 m/s^{2} is the acceleration due gravity

So, with these conditions the equation is rewritten as:

h=\frac{g}{2}t^{2} (2)

h=\frac{9.8 m/s^{2}}{2}(0.5 s)^{2} (3)

Finally:

h=1.22 m

If the distance between us and a star is doubled, with everything else remaining the same, the luminosity If the distance betwee
natima [27]

Answer:

The luminosity remains the same, but the apparent brightness is decreased by a factor of four.

Explanation:

The apparent brightness, F = L/4πr² where L = luminosity and r = distance between us and the star.

Since L is independent of the distance between us and the star, it is constant, then

F ∝ 1/r²

So, F₁/F₂ = r₂²/r₁² where F₁ = apparent brightness at r₁ and F₂ = apparent brightness at r₂

If the distance is doubled, that is r₂ = 2r₁, then

F₁/F₂ = r₂²/r₁²

F₁/F₂ = (2r₁)²/r₁²

F₁/F₂ = 4r₁²/r₁²

F₁/F₂ = 4

F₂ = F₁/4

So, since the luminosity is constant, <u>the luminosity remains the same, but the apparent brightness is decreased by a factor of four.</u>
