Answer:
Like gases, the particles in plasmas are constantly moving at high speeds, and do not have a definite shape or volume. Plasma is formed when the kinetic energy of the molecules in a gas gets very large and the temperature gets very high. This causes electrons to be released by the atom, creating ionized particles, which are positive ions and negative electrons.

Plz help me. I need urgent Why a magnetic compass is used to determine direction? Why a nail gets magnetized when kept close to magnet? Why two pins get attracted by bar magnet maintain distance between ends?
Answer:
Compasses are mainly used in navigation to find direction on the earth. This works because the Earth itself has a magnetic field which is similar to that of a bar magnet. The compass needle aligns with the Earth's magnetic field direction and points north-south. Also, In a magnet all the domains are oriented in the same direction. In the case of a nail, the domains can be aligned in the same direction causing the nail to become magnetic. That is because if you hang a bar magnet from a thread, the north pole will point to magnetic north. When you bring one north pole close to another north pole they repel each other. You can feel the two magnets pushing each other apart.

Pictured is an animal cell and a plant cell. Which organelle labeled in the plant cell produces the energy for the cell?
Answer:
Mitochondria
Mitochondria. Mitochondria are double membrane-bound cell organelles responsible for the supply and storage of energy for the cell.
Explanation:
The organelle labeled as "mitochondria" in the plant cell produces the energy for the cell through the process of cellular respiration.
What are mitochondria?Mitochondria are organelles found in most eukaryotic cells. They are often referred to as the "powerhouses" of the cell because their main function is to produce energy in the form of ATP (adenosine triphosphate) through a process called cellular respiration.
Mitochondria have an outer membrane and an inner membrane with folds called cristae. The space between the two membranes is called the intermembrane space, while the space inside the inner membrane is called the mitochondrial matrix. The mitochondrial matrix contains enzymes and other molecules needed for the metabolic reactions of cellular respiration.
Cellular respiration is a process that converts glucose and oxygen into ATP, which is the primary energy source for cells. Mitochondria play a key role in this process by breaking down glucose through a series of chemical reactions that ultimately produce ATP. The energy stored in ATP molecules can then be used by the cell for various cellular processes, such as muscle contraction, protein synthesis, and the maintenance of the cell's membrane potential.
In addition to their role in ATP production, mitochondria are also involved in other important cellular functions, such as calcium signaling, apoptosis (programmed cell death), and the synthesis of certain lipids and heme groups. Mitochondrial dysfunction has been implicated in a number of diseases, including Parkinson's disease, Alzheimer's disease, and diabetes.
Therefore, Through the process of cellular respiration, the organelle in the plant cell known as the "mitochondria" generates the energy for the cell.

A monorail starts from rest and accelerates at a rate of 2.2m/s2 for 10s.Then it runs at a constant speed for 74s and then slows down at a rate of 1.5m/s2
Answer:
d = 4217 m
Explanation:
Case 1.
Initial velocity, u = 0
Acceleration, a = 2.2 m/s²
Let d₁ is the distance in case 1. Using second equation of motion as follows :
[tex]d_1=ut+\dfrac{1}{2}a_1t_1^2\\\\\text{Here, u =0}\\\\d_1=\dfrac{1}{2}\times 2.2\times 10^2\\\\d_1=110\ m[/tex]
Let d₂ in the distance in case 2. Using second equation of motion as follows :
[tex]d_2=ut+\dfrac{1}{2}a_2t_2^2\\\\\text{Here, u =0}\\\\d_2=\dfrac{1}{2}\times 1.5\times 74^2\\\\d_2=4107\ m[/tex]
Total distance,
D = d₁ + d₂
D = 110 + 4107
D = 4217 m
Hence, the total distance covered is 4217 m.
Robin jogs with an average speed of 5.5 m/s for 3.3s.
What was her distance travelled in meters?
Answer:
18.15m
Explanation:
Speed * Time = Distance
5.5 * 3.3 = 18.15m
The distance traveled by Robin is equal to 18.15 m with an average speed of 5.5 m/s for 3.3s.
What is the average speed?The average speed can be explained as the total distance covered by the object in a definite time. The average speed can be considered a scalar quantity as it exhibits magnitude and no direction.
The average speed of a physical system can be determined from the ratio of the total distance traveled by the system to the time taken to cover that distance.
The average speed equation of a physical system can be written as follows:
Average speed = Total distance/total time taken
Given, the average speed of the Roin, = 5.5 m/s
The time is taken by Robin for jogging = 3.3 s
The average speed of the Robin can be determined as:
Average spped = Distance/ time
5.5 = Distance/3.3
Distance traveled by Robin = 5.5 × 3.3 = 18.15 m

1) Describe how the atoms of a solid differ from the atoms of a liquid.
Answer:
liquid are close together with no regular arrangement. solid are tightly packed, usually in a regular pattern.
The atoms of solids and liquids are different from each other in many ways as discussed below.
We have a solid and a liquid.
We have to describe how the atoms of a solid differ from the atoms of a liquid.
What is Atom?An Atom smallest unit into which matter can be divided without the release of electrically charged particles.
According to the question, the following differences exists between the atoms of solids and liquids -
In solids the atoms are tightly packed while in liquid they are loosely packed.In solids the density of atoms within a specific volume is very high while in liquid it can be either high or low.In solids, atoms are not free to move and they can only oscillate about their mean position while in liquid the atoms are free to move.Hence, it can be seen that the atoms of solids and liquids are quite different from each other.

The gravitational acceleration on Earth is 9.8 m/s2. What is the weight of a car on Earth (to the nearest whole number) if it has a mass of 1360 kg? 14 N 139 N 1333 N 13,328 N
Weight = (mass) x (gravitational acceleration where the mass is)
Weight = (1360 kg) x (9.8 m/s²)
Weight = 13,328 kg-m/s²
That's 13,328 Newtons
Given:-
Mass (m) of the car = 1360 kgAcceleration due to gravity (g) = 9.8 m/s²To Find: Weight (W).
We know,
W = mg
where,
W = Weight,m = Mass &g = Acceleration due to gravity.Thus,
W = (1360 kg)(9.8 m/s²)
→ W = 13,328 N (D)

After you let go of a bowling ball, is there a force pushing it so that it keeps moving
forward? Explain.
Explanation:
No, the ball keeps moving forward due its momentum.
A net force causes an object to accelerate, which means it speeds up, slows down, or changes direction. A bowling ball does not speed up after you let go, so there is no forward force.
