For a solar eclipse to occur the moon must be between the earth and the sun (the light of the sun is blocked)'

By definition this is a new moon (which occurs when the moon cannot be seen because it is located between the sun and the earth).

Oxidation of certain metals in rock and acid rain breaking down compounds in rock statues are examples of chemical weathering.

When chemicals are diluted and dissolved in water, they seep and percolate down the surfaces of rocks, causing chemical weathering. Chemical weathering occurs in humid tropical regions and other places with high temperatures and a sufficient supply of water.

The reaction of chemicals in water or air causes minerals to change in composition as chemical weathering takes place. Additionally, this causes the breakdown of rocks. Leaching is the process of carrying away some components of rock breakdown through rocks and soil.

These materials may eventually be transported by the water to rivers and the sea. The oceans' saltiness comes from this source. Oxidation, the breakdown of calcium carbonate, and   acid rain breaking down compounds in rock statues by chemical reaction are examples of chemical weathering.

Answer:

41.66 km/h

Explanation:

Calculate the distance of 1st travel :

v = d/t

25 km/h = d/1 h

d = 25 km/h × 1 h

Calculate the distance of 2nd travel :

v = d/t

50 km/h = d/2 h

d = 50 km/h × 2 h

Calculate the velocity of trip :

v = d/t

v = (25 + 100)/(1 + 2)

v = 125 km/3 h

So, my velocity for the trip is 41.66 km/h

Answer:

6.86g/mL

Explanation:

The density of the metal would be approximately 6.859 grams per milliliter (g/mL).

Given that the mass (m) is 78.2 g and the volume (V) is 11.4 mL, we can plug these values into the formula:

Density is a physical property that quantitatively expresses how much mass is contained within a given volume of a substance. In other words, it is a measure of how tightly packed the particles or molecules of a material are. Mathematically, density is defined as the mass of an object (or substance) divided by its volume. It is often denoted by the Greek letter "ρ" (rho).

Density is defined as mass per unit volume. The formula for density is:

Density (ρ) = Mass (m) / Volume (V)

Density (ρ) = 78.2 g / 11.4 mL

Now, let's calculate the density:

Density (ρ) = 6.859 g/mL

So, the density of the metal is approximately 6.859 grams per milliliter (g/mL).

We have that with v_1 =v this goes to show that  the velocity of the bigger block after the collision takes place is v

From the question we are told

Suppose the blocks collide elastically. picking the positive direction to the right, what is the velocity of the bigger block after the collision takes place?

Generally the equation for Momentum   is mathematically given as

P=mv

Therefore

[tex]m_1v_2=m_2v_2[/tex]

Hence

[tex]v_1=\frac{m_2v_2}{m_1}[/tex]

Therefore

[tex]v_1=\frac{mv_2}{2m}\\\\v_1=\frac{v_2}{2}[/tex]

Hence

[tex]2v+v=v_1+v_2\\\\v_1=v[/tex]

Now

with v_1 =v this goes to show that  the velocity of the bigger block after the collision takes place is v

The mass given is 25.0 grams. As for the change in temperature, I will assume that it start off at room temperature, 25°C.

W = F × s

W = 15kN × 40 m

W = 15.000 N × 40 m

W = 600.000 J

P = W/t

P = 600.000 J/2 s

P = 300.000 Watt

P = 300kWatt
