Answer:
The correct answer is - rain.
Explanation:
At 32 degrees c or zero degrees Celsius, droplets of water in the atmosphere do not freeze as it is not the temperature at which water freezes but it is the temperature at which ice melts.
At this temperature the water changes its state, below 32 degrees Fahrenheit the water freezes but in the atmosphere, it not freezes necessarily and remains in the liquid state and called super-cooled liquid or water. Above this temperature, water in liquid state.
Thus, the precipitation is in the form of rain.

Explanation:
is bird seed homogeneous or heterogeneous
Answer:
heterogeneous
In order to give birds a varied and balanced diet, commercial bird seed blends typically include a range of seeds, grains, and other substances. As a result, bird seed is frequently categorised as a heterogeneous blend.
A seed is referred to as homogenous if its genetic makeup, size, shape, and other traits are all consistent. To guarantee consistency in the ensuing plants, these seeds are typically created through controlled breeding or genetic manipulation. A heterogeneous seed, on the other hand, is one that varies in genetic makeup, size, shape, and attributes. These seeds frequently result from cross-pollination or natural pollination between various species or kinds.

Which statement best explains what happens to a leaf when it has lost much-needed water?
Answer:
its turgor pressure decreases
Explanation: This is also important because this function regulates water loss within the plant. Lower turgor pressure can mean that the cell has a low water concentration and closing the stomata would help to preserve water. :-)
When a leaf loses much-needed water, its turgor pressure would decrease. Hence Option A is Correct
What is Turgor pressure ?Turgor Pressure is created in the cells of a leaf when there is enough water. The water stretches the cell membrane outward, creating a kind of pressure.
When the cells lose water, the cell membrane shrinks inward and loses the supporting pressure.
Thus, the turgor pressure created by the presence of water is lost by the absence of water.
The absence of water also affects the rate of photosynthesis and transpiration negatively and not positively. A leaf losing water has no bearing on the atmospheric pressure.

(b) disappears into the wood.
(c) exerts an equal force back on the hammer.
(d) moves at a constant speed.
Answer:
C
Explanation:
When a hammer strikes and exerts force on a nail, the nail exerts an equal force back on the hammer. Option C. This is further explained below.
What is Newton’s third law of motion?Generally, According to Newton's third law, when two bodies contact, they apply forces to each other that are equal in magnitude and opposing in direction.
In conclusion, Newton’s third law of motion certifies that the nail exerts an equal force back on the hammer.

Complete the following nuclear bombardment equation by filling in the nuclear symbol for the missing species.
²³⁵₉₂U + ¹₀n → ? + ¹³⁹₅₄Xe + 3 ¹₀n
Answer:
Strontium [tex]94_{38}[/tex]Sr
Explanation:
By the law of mass conversion the nuclear mass remains constant in a reaction which means initial mass and atoic number will be equal to final atomic number and atomic mass respectively.
²³⁵₉₂U + ¹₀n → ? + ¹³⁹₅₄Xe + 3 ¹₀n
Here atomic mass =
235 + 1 = A + 139+3 ( A -= atomic mass of ?)
A = 236 - 142
A = 94
And, atomic number would be =
92 = B + 54
B = 92 - 54
B = 38
So, the atomic number of ? will be 38 and atomic mass will be = 94
The element with 38 atomic number is = Strontium [tex]94_{38}[/tex]Sr
The missing species in the equation is ⁹⁴₃₈Sr
Let the missing species be ᵇₐY
We can write the equation as:
²³⁵₉₂U + ¹₀n → ᵇₐY + ¹³⁹₅₄Xe + 3¹₀n
Next, we shall determine the value of b235 + 1 = b + 139 + 3(1)
236 = b + 139 + 3
236 = b + 142
Collect like terms
236 – 142 = b
b = 94Next, we shall determine the value of a92 + 0 = a + 54 + 0
92 = a + 54
Collect like terms
92 – 54 = a
a = 38Finally, we shall determine Yb = 94
a = 38
Y =?ᵇₐY => ⁹⁴₃₈Y => ⁹⁴₃₈Sr
The balanced equation is:

The ability to exert a force that causes an item to move is what is meant by the definition of energy as the "power to accomplish work." Even though the definition is unclear, the meaning is clear: energy is simply the force that moves things. Potential energy and kinetic energy are the two categories of energy.
Which source of energy has a direct impact on climate change?Renewable energy is frequently cited as the most important shift the world can make to fend off the worst consequences of global warming. This is due to the fact that renewable energy sources like solar and wind don't produce greenhouse gases like carbon dioxide, which contributes to global warming.
Wind, sunlight, bioenergy (organic matter burned as fuel), and hydroelectricity, including tidal energy, are a few examples of renewable energy sources.
The ability to exert a force that causes an object to move is what the definition of energy as "power to accomplish work" refers to.

Explain why the electron configuration of 2-3-1 represents an atom in an excited state?
Answer:
See explanation
Explanation:
If we look at the electron configuration closely, we will discover that the element must have had a ground state electron configuration of 2,4.
This is because, the innermost shell usually holds two electrons while the outer shells hold eight electrons each. The four electrons must be accommodated in the second shell in the ground state configuration of the compound.
However, when the atom is excited, one electron from this shell may move to the third shell to give the excited state configuration 2-3-1 as shown in the question.
