Answers
Answer:
I believe it is vacuum of space
Explanation:
Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.

LA 7.0 liter balloon at room temperature (22°C) contains hydrogen gas. If the
balloon is carried outside to where the temperature is 30°C, what volume will the
balloon occupy?
Answers
Answer:
Explanation: Convert temperatures to Kelvins.
22 C = 295 K
30 C = 303 K
According to Charles' law:
V1 / T1 = V2 / T2
7 / 295 = V2 / 303
V2 = (303 * 7) / 295
V2 = 7.18983 Litres which rounds to 7.19 litres.

Suppose two equal mass cars traveling with equal speeds in opposite directions inelasticcollide head on and stick together. What fraction of the energy is dissipated
Answers
A collision which is inelastic is one in which the internal energy changes.
All the kinetic energy is dissipated
Reasons:
The given parameters are;
The mass of one car = The mass of the second car in the collision = m
The type of collision = Inelastic collision
The speed of each of the cars in the collision = v and -v
Solution:
In an inelastic collision, we have;
[tex]m_1 \cdot v_{1i} + m_2 \cdot v_{2i} = (m_1 + m_2) \cdot v_f[/tex]
Therefore, we get;
[tex]m \cdot v_{i} -m \cdot v_{i} = 0= 2 \cdot m \cdot v_f[/tex]
Which gives;
[tex]v_f = 0[/tex]
The collision is an example of a perfectly inelastic collision, and the final velocity after the collision is zero.
The change in the energy is [tex]\Delta K.E. = K.E._{final} - K.E._{initial}[/tex]
[tex]K.E._{initial}[/tex] = 0.5·m·v² + 0.5·m·v² = m·v²
ΔK.E. = 0.5·(2·m)×0 - 0.5·m·v² + 0.5·m·v² = -m·v²
ΔK.E. = -m·v²
The negative sign stands for energy given out, which gives;
The energy dissipated = m·v² (The total initial kinetic energy)
Therefore, all the kinetic energy is dissipated

near earth's surface is the weight of an object in newtons about 10 times it's mass in kilograms?
Answers
Answer:
Weight varies with location depending upon the acceleration due to gravity eg. for a mass m = 10kg on Earth it`s weight is W = mg = 10 x 10 = 100N.
Explanation:
Near Earth's surface, the weight of an object in newtons is 10 times its mass in kilograms. This relationship of the acceleration is due to gravity on Earth, which is 9.81 m/s².
Mathematically, it can be expressed as:
Weight (in newtons) = Mass (in kilograms) × Acceleration due to gravity
So, an object with a mass of, for example, 5 kg, its weight near the Earth's surface would be:
Weight = 5 kg × 9.81 m/s² = 49.05 N
The weight in newtons is roughly 10 times the mass in kilograms of objects near the Earth's surface. The given statement is correct.

Hector wants to pay more attention to his diet, then he must count calories and be sure to measure every portion. Hence, option A is correct.
What is Diet?The food and beverages a person routinely consumes are referred to as their diet in the field of nutrition (or a group). The diet, or one that fulfills the physical needs of an individual, may be controlled during a specific therapy for a disease or management of a specific health condition.
A diabetic person's diet could be limited to a particular list of foods and beverages that can assist control blood sugar levels, for example. Numerous fiber, non-starchy fruits, and vegetables are part of the diabetes diet that is advised for patients. Rich in carbohydrates, starchy meals have the potential to raise blood sugar levels when consumed in significant quantities.
If Hector wants to pay attention to his diet and also doesn't want to get hung up on any rigid program then he must count calories and ensure that he must measure every portion.

Energy transformation is demonstrated in the diagram is solar energy to heat energy.
What is energy?Energy is the ability or capability to do tasks, such as the ability to move an item (of a certain mass) by exerting force. Energy can exist in many different forms, including electrical, mechanical, chemical, thermal, or nuclear, and it can change its form.
Solar radiation is absorbed at the surface of a receiver, which includes oris in touch with flow passageways through which a working fluid moves, during thermal conversion operations. Heat is delivered from the heating receiver to the working fluid, which might be air, water, oil, or molten salt.

Answers
Answer:
answer is A hope this helps
Explanation:
According to the characteristics of non-metals such as nitrogen and phosphorous which are solids they are also brittle.
What are the characteristics of non-metals?Non-metals do not possess luster and are dull . They are not malleable and ductile and are soft due to the covalent bonding present in them . Non-metals on the other hand owing to their soft nature have low melting points.
Non-metals have four to seven valence electrons owing to which they usually form covalent bonds. They are poor conductors of heat and electricity and are mostly in liquid or gaseous state.They are widely used in the manufacture of fertilizers , in rocket fuels and in the form of graphite in pencil leads.
Non-metals have high ionization energies and high electronegativities.

when light passes through an ordinary window pane, its angle of emergence is
Answers
when light passes through an ordinary window pane, its angle of emergence is the same as its angle of incidence light refracts when traveling from air into glass because light travels slower in glass then in air
Light speeds up and changes direction when it passes through water or glass at an angle and enters the atmosphere. Turning away from the usual line, the light. Imagine a tractor transitioning from a slow-moving, muddy, grassy area to a quick-moving road.
What light passes through an ordinary window pane?Light refracts while passing from air into glass because light travels more slowly in glass than it does in air. When light passes through a typical window pane, its angle of emergence and angle of incidence are the same.
When light travels from the less dense air into the denser glass or water, what actually happens is that it slows down. The light ray also changes direction as a result of this slowing down. Refraction is brought on by a change in the speed of the light.
Therefore, When light rays bounce off a surface, transition from one transparent medium to another, or proceed through a medium whose composition is constantly changing, they change direction.
