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.

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.

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

The electric motor of a model train accelerates the train from rest to 0.620 m/s in 21ms. The total mass of the train is 825 g. find the average power delivered to the train during its acceleration.
Explanation:
Average power = change in energy / change in time
P = ΔE / Δt
P = (½ mv²) / t
P = (½ (0.825 kg) (0.620 m/s)²) / (0.021 s)
P = 7.55 Watts

A group of friends are doing some archery.
When Brian fully stretches the bow, it stores 10 J of energy.
Describe the energy transfer that occurs as Brian stretches the bow.
[2 marks]
Answer: potential to kinetic/mechanical
Explanation:
When Brian fully stretches the bow, it stores 10 J of energy. The energy transfer that occurs as Brian stretches the bow will be from the potential energy to the kinetic energy.
What is the law of conservation of energy?According to the Law of Conservation of Energy, energy can neither be created nor destroyed, but it can be transferred from one form to another.
The total energy is the sum of all the energies present in the system. The potential energy in a system is due to its position in the system.
In the above problem, the potential energy gets converted into kinetic energy at the expense of the loss of gravitational potential energy between the two positions.
Friends are practicing archery together. The bow holds 10 J of energy when Brian stretches it to its maximum length. As Brian extends the bow, energy will go from the potential energy to the kinetic energy.

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.

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 drunk college student decides to try to do a perfect swan dive from his apartment window into the pool below. The edge of the pool is 5 meters from the base of the building and his window is on the 3rd floor, which is 8 meters from the ground. If he jumps out the window horizontally at a speed of 4 m/s, does he make it into the water or..
Answer:
He barely makes it but hit his leg on the pool edge.
Explanation:
Using kinematic formula: Δx=[tex]v_{0}t+(1/2)at^2[/tex]
We can plug in delta x, v zero, and acceleration.
delta x = 8 meters, v0 = 0. a = 9.8
