Which option BEST describes the position of the Sun, the Moon, and Earth during the new moon phase and the MOST LIKELY effect of

the phase on the petrel?
A.

The Sun, the Moon, and Earth are in a straight line, with Earth between the Sun and the Moon. The petrel will be very active because there will be a lot of light reflected by the Moon.

B.

The Sun, the Moon, and Earth are in a straight line, with the Moon between the Sun and Earth. The petrel will be less active because there will not be any light reflected by the Moon.

C.

The Sun, the Moon, and Earth are in a straight line, with the Moon between the Sun and Earth. The petrel will be very active because there will be a lot of light reflected by the Moon.

D.

The Sun, the Moon, and Earth are in a straight line, with Earth between the Sun and the Moon. The petrel will not be very active because there will not be any light reflected by the Moon..

Light of wavelength 597 nm falls on a double slit, and the first bright fringe of the interference pattern is seen at an angle o
Kazeer [188]

Answer:

2.2 µm

Explanation:

For constructive interference, the expression is:

d\times sin\theta=m\times \lambda

Where, m = 1, 2, .....

d is the distance between the slits.

Given wavelength = 597 nm

Angle, \theta  = 15.8°

First bright fringe means , m = 1

So,

d\times sin\ 15.8^0=1\times \597\ nm

d\times 0.2723=1\times \597\ nm

d=2192.43481\ nm

Also,

1 nm = 10⁻⁹ m

1 µm = 10⁻⁶ m

So,

1 nm = 10⁻³ nm

Thus,

<u>Distance between slits ≅ 2.2 µm</u>

You build a grandfather clock, whose timing is based on a pendulum. You measure its period to be 2s on Earth. You then travel wi
Elenna [48]

Answer:

\frac{g_{2}}{g_{1}} = \frac{1}{4}

Explanation:

The period of the simple pendulum is:

T = 2\pi\cdot \sqrt{\frac{l}{g} }

Where:

l - Cord length, in m.

g - Gravity constant, in \frac{m}{s^{2}}.

Given that the same pendulum is test on each planet, the following relation is formed:

T_{1}^{2}\cdot g_{1} = T_{2}^{2}\cdot g_{2}

The ratio of the gravitational constant on planet CornTeen to the gravitational constant on planet Earth is:

\frac{g_{2}}{g_{1}} = \left(\frac{T_{1}}{T_{2}} \right)^{2}

\frac{g_{2}}{g_{1}} = \left(\frac{2\,s}{4\,s} \right)^{2}

\frac{g_{2}}{g_{1}} = \frac{1}{4}
