The distance and parallax are inversely related. We can find the distance using the following equation:

where d is distance and p is parallax.

We are given the parallax of the comet relative to the moon, and we are looking for the distance to the comet relative to the moon's distance, so wee can plug in the following value:

The distance is 40 times as far away as the moon.

**Answer:**

a material with a **large** specific heat can absorb a great deal of thermal energy without a great change in temperature.

**Explanation:**

The specific heat capacity of an object is the amount of energy needed to raise the temperature of 1 kg of mass of a substance by .

Mathematically, it is given by:

where

Q is the amount of energy supplied

m is the mass of the substance

is the change in temperature of the substance

The equation can be rewritten as:

Therefore, we see that the increase in temperature of a substance is inversely proportional to its specific heat capacity.

Therefore, a material with a large specific heat can absorb a great deal of thermal energy without a great change in temperature.

**Answer:**

F = 0.535 N

**Explanation:**

Let's use the concepts of energy, at the highest and lowest point of the trajectory

Higher

Em₀ = U = mg y

Lower

= K = ½ m v²

Emo =

mg y = ½ m v2

v = √ 2gy

y = L - L cos θ

v = √ (2g L (1-cos θ))

Now let's use Newton's second law n at the lowest point where the acceleration is centripetal

F = ma

a = v² / r

In turning radius is the cable length r = L

F = m 2g (1-cos θ)

Let's calculate

F = 2 1.25 9.8 (1 - cos 12)

F = 0.535 N

Meters it the SI unit for measuring length.

**Answer:**

The wavelength of the light is 555 nm.

**Explanation:**

according to Bragg's law..

n×λ = d×sin(θ)

n is the fringe number

λ is the wavelength of the light

d is the slit separation

θ is the angle the light makes with the normal at the fringe.
