Large objects that form dense gravity wells in space A. Galaxies B. Star C. Nebulae D. Black holes.
Answer:
D. Black Holes
Explanation:
Black holes are large objects that form dense gravity wells in space. Their gravitational pull is so strong that even light cannot escape it.
Large objects that form dense gravity wells in space are stars and blackholes. The correct answer is option B and D.
Gravity: it is referred to as force of attraction experienced by a body having mass, towards the center of Earth.
Both stars and black holes are massive objects that exert a significant gravitational force due to their mass. They create what is known as a gravity well, which is a region of space where the gravitational pull is strong enough to affect the motion of nearby objects.
On the other hand, Galaxies and nebulae, are not individual objects with sufficient mass to form dense gravity wells. Galaxies consist of a collection of stars, gas, and dust, and while they have a collective gravitational influence, it is not concentrated in a single massive object like a star or black hole. Whereas, Nebulae are interstellar clouds of gas and dust, which do not possess the mass required to create significant gravity wells.
Therefore, the correct options from the given list that form dense gravity wells in space are B. Star and D. Black holes.

what happens to the wavelength as frequency increases
Explanation:
The higher the wavelength, the lower its frequency and energy
Answer:
As frequency increases wavelength decreases in size
Explanation:
The wavelength of the wave is inversely proportional to the frequency of the wave as the speed of the wave remains constant.
v = fλ ( v - speed, f - frequency, -wavelength)
[tex]\frac{v}{\lambda}[/tex] = f
Therefore at constant speed:
f ∝ [tex]\frac{1}{\lambda}[/tex] (inversely proportional)

What term describes the temperature at which a substance can change state from a liquid to a gas?
A. Boiling point
B. Melting point
C. Freezing point
D. Specific heat
Option A. Boiling point.
Explanation:
When you heat the water, the water gets converts into gaseous form.
As you know that water is in liquid form. So, when you heat the water, the water molecules absorbs the heat and get dispersed from one another molecules. i.e., molecules go far from the other molecules as they absorbed heat.
The term describes the temperature at which a substance can change state from a liquid to a gas, is boiling point. Therefore, option A is correct.
What is boiling point ?The temperature at which a liquid's vapor pressure equals the pressure around it and the liquid transforms into a vapor is known as the boiling point of a substance. A liquid's boiling point varies depending on the atmospheric pressure in the area.
Boiling point and saturation temperature are synonyms. Sometimes the measurement's pressure serves as a definition for the boiling point. The International Union of Pure and Applied Chemistry was founded in 1982.
The boiling point of a sample can be calculated using a number of techniques, such as distillation, reflux, and a Thiele tube. The simplest approach makes use of a Thiele tube and has the benefit of requiring less than 0.5mL of substance.
Thus, option A is correct.

find the average speed of a person who swims 105 m in 70 s
Answer:
v = 1.5 m/s
Explanation:
Given that,
Distance covered by a person, d = 105 m
Time taken, t = 70 s
We need to find the average speed of the person. We know that the average speed is given by :
[tex]v=\dfrac{d}{t}\\\\v=\dfrac{105\ m}{70\ s}\\\\v=1.5\ m/s[/tex]
So, the average speed of the person is equal to 1.5 m/s.

Gas is confined in a metal tank in the figure. At 20.20°C, the gas exerts a pressure of 8.532 atm.
After heating the tank, the pressure of the gas increases to 10.406 atm. What is the temperature of
the heated gas?
Answer:
The temperature of the heated gas is 357.6 K (or 84.6 C)
Explanation:
Gay Lussac's law indicates that, as long as the volume of the container containing the gas is constant, as the temperature increases, the gas molecules move faster. Then the number of collisions with the walls increases, that is, the pressure increases. That is, the pressure of the gas is directly proportional to its temperature.
In short, when there is a constant volume, as the temperature increases, the pressure of the gas increases. And when the temperature is decreased, the pressure of the gas decreases.
So, this law indicates that the quotient between pressure and temperature is constant:
[tex]\frac{P}{T} =k[/tex]
You want to study two different states, an initial state 1 and a final state 2. Then it is true:
[tex]\frac{P1}{T1} =\frac{P2}{T2}[/tex]
In this case:
P1= 8.532 atmT1= 20.20 C= 293.2 K (being 0 C= 273 K)P2= 10.406 atmT2= ?Replacing:
[tex]\frac{8.532 atm}{293.2 K} =\frac{10.406 atm}{T2}[/tex]
Solving:
[tex]T2*\frac{8.532 atm}{293.2 K} =10.406 atm[/tex]
[tex]T2=10.406 atm*\frac{293.2 K}{8.532 atm}[/tex]
T2= 357.6 K
The temperature of the heated gas is 357.6 K (or 84.6 C)
The new temperature of the heated gas when the pressure increase to 10.406 atm is 84.60 °C
Data obtained from the question Initial temperature (T₁) = 20.20°C = 20.20 + 273 = 293.20 KInitial pressure (P₁) = 8.532 atm Volume = constant New pressure (P₂) = 10.406 atmNew temperature (T₂) =? How to determine the new temperatureThe new temperature of the gas can be obtained by using the combined gas equation as illustrated below:
P₁V₁ / T₁ = P₂V₂ / T₂
Since the volume is constant, we have:
P₁ / T₁ = P₂ / T₂
8.532 / 293.20 = 10.406 / T₂
Cross multiply
8.532 × T₂ = 293.20 × 10.406
Divide both side by 8.532
T₂ = (293.20 × 10.406) / 8.532
T₂ = 357.6 K
Subtract 273 from 357.6 K to express in degree celsius
T₂ = 357.6 – 273
T₂ = 84.60 °C
