If the plane of the moon's orbit were the same as the ecliptic plane, there would be a lunar eclipse

Physics
1 answer:
Murrr4er [49]3 years ago
5 0

Answer:

Option B

Explanation:

An lunar eclipse occurs when the Earth comes in between the Sun and the moon when all the three are aligned in space and the Earth casts its shadow on the phase of the full moon and thus darkens it usually the moon turns into a shade of copper red.

For the eclipse to occur every month the Earth's orbit around the sun must coincide with the moon's orbit around the earth.

It takes about a month for the moon to orbit the Earth and if the plane of the ecliptic orbit is the same as that of the orbit of the moon around the earth then there would be at least two lunar eclipses in a month, one at full moon and the other one fortnightly.

If the amount of gas in a sealed container increases, what happens to the pressure in the container
lilavasa [31]
The pressure law states that for a constant volume of gas in a sealed container the temperature of the gas is directly proportional to its pressure. This can be easily understood by visualising the particles of gas in the container moving with a greater energy when the temperature is increased.

andre [41]

Answer:  10 m/s

We're told the speed is constant, so it's not changing throughout the time period given to us. So throughout the entire interval, the speed is 10 m/s.

One speed skater starts across a frozen lake at an average speed of 8 m/s. Ten seconds later, a second speed skater starts from
Luba_88 [7]

Answer:

40 s

Explanation:

After 10 seconds, the first skater would have a 8m/s * 10s = 80 m head start

Let t be the number of seconds after the second skater starts will the second skater overtake the first skater

The distance traveled by the first skater after t seconds is

s_1 = v_1t = 8t

Similarly the distance traveled by the 2nd skater after t seconds is

s_2 = v_2t = 10t

Since the 2nd skater catches up to the 1st one after 80 m behind, the distance traveled by the 2nd one must be 80m greater than the distance of the 1st skater

s_2 = s_1 + 80

We can substitute s_1 = 8t, s_2 = 10t

10t = 8t + 80

2t = 80

t = 80 / 2 = 40 s

kvv77 [185]

Answer:

88.8 m/s= Speed of wave propagation in the required mode.(3 loops)

Explanation:

When there are 3 loops.  

the total length = L = 3 λ /2

⇒ λ  = 2 L / 3 = 2 ( 1.11 ) / 3 = 0.74 m

Velocity = v = f λ = (120)(0.74) = 88.8 m/s

What landform is created when magma squeezes between rock layers to form a hardened slab of rock?
Zigmanuir [339]
<span>D. sill

A sill forms when hot magma squeezes between layers of rock to form a hardened sheet of rock. A sill is basically a tabular sheet intrusion between old layers of sedimentary rock, volcanic beds, or in the direction of foliation inherent in metamorphic rock. The word sill means a concordant intrusive sheet.</span>
