Answer: 6.0 m/s/s
Explanation: If the net force acting on an object is halved, the acceleration of the object will also be halved. Therefore, if the object has an acceleration of 12.0 m/s/s and the net force acting on it is halved, the new acceleration of the object would be 12.0 m/s/s / 2 = 6.0 m/s/s.

The inhabitants of the island don’t speak English, but you notice that the local time is 4 hours earlier than your watch set to Southern California time. Approximately what longitude are you at?
2. Your grandma recently moved to Hawaii (Hawaiian Standard Time Zone). You always call her at 8:00pm on her birthday (November 6th). You are at home in Southern California. What time do you need to call her to reach her at 8:00pm Hawaiian Time?
3. You are flying from London, England to LAX. It is noon in London and your flight takes 10 hours. What time will your flight land in LAX
Answers
1) The longitude is approximately 118 degrees West (the meridian for Pacific Standard Time is 122 degrees West).
2) To call your grandma at 8:00 pm Hawaiian Time, you need to call her at 11:00 pm Southern California Time.
3) If it is noon in London, it is 4:00 am in LAX. Your flight takes 10 hours, so it will land in LAX at 2:00 pm (14:00) LAX time.
1. To figure out your longitude when you crash landed on an island in the Pacific Ocean, you need to know the time difference between your watch set to Southern California time and the local time on the island.
The time difference is 4 hours earlier, which means that you are 60 minutes * 4 = 240 minutes (4 hours) behind Pacific Standard Time (PST).
To convert minutes to degrees, you can use the fact that there are 60 minutes in a degree.
Therefore, 240 minutes is equal to 240/60 = 4 degrees west of the PST meridian.
So, your longitude is approximately 118 degrees West (the meridian for Pacific Standard Time is 122 degrees West).
2. There is a 3-hour time difference between Hawaiian Standard Time and Southern California Time.
So, to call your grandma at 8:00 pm Hawaiian Time, you need to call her at 8:00 pm + 3 hours = 11:00 pm Southern California Time.
3. London is 8 hours ahead of LAX (Pacific Standard Time) in terms of time zones.
So, if it is noon in London, it is 4:00 am in LAX. Your flight takes 10 hours, so it will land in LAX at 4:00 am + 10 hours = 2:00 pm (14:00) LAX time.

Which magnets need electric current for magnetism?
a. Bar magnets b. Temporary magnets c. Permanent magnets magnets
Answers
Temporary magnets require electric current to produce magnetism and magnetic field lines B) Temporary magnets
In electromagnets, their magnetism is dependent on electricity with an iron core in the center. If we add an iron core to a solenoid, we can increase its magnetic field strength . When we connect a battery to a solenoid and wrap the sanded copper wire around a nail, a magnetic field is created. This force is generated by the magnetic field that's created when current flows through the coil.
As long as there is a direct current running through the coil, the nail will retain its magnetic properties. However, once the current stops, the magnetism of the nail is lost . Creating electromagnets can be achieved by winding wire around the iron core.

The substrate Glycogen is utilized in which energy system(s)?.
Answers
The substrate Glycogen is utilized in two primary energy systems: the Glycolytic System (also known as the Anaerobic Lactic System) and the Oxidative System (also known as the Aerobic System).
1. Glycolytic System: This energy system rapidly breaks down glycogen into glucose, which then undergoes glycolysis to produce ATP (adenosine triphosphate). This system is anaerobic, meaning it does not require oxygen and is suitable for short, high-intensity activities lasting up to 2 minutes.
2. Oxidative System: In this energy system, glycogen is first broken down into glucose, which then undergoes glycolysis, the citric acid cycle, and oxidative phosphorylation to produce ATP. This system is aerobic, meaning it requires oxygen and is suitable for longer, lower-intensity activities lasting more than 2 minutes.
The substrate glycogen is utilized in both the Glycolytic (Anaerobic Lactic) and Oxidative (Aerobic) energy systems to produce ATP for various physical activities.

A ball with a momentum of 16 kg.M/s strikes a ball at rest. What is the total momentum of both the balls after the collision.
Answers
Answer:
Total momentum = 16 Kgm/s
Explanation:
Let the momentum of the two balls be A and B respectively.
Momentum A = 16 kgm/s
Momentum B = 0 kgm/s (since the ball is at rest).
Total momentum = A + B
Total momentum = 16 + 0
Total momentum = 16 Kgm/s
Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.
Mathematically, momentum is given by the formula;
\( Momentum = mass * velocity \)

Imagine that a certain bacterial species divides by binary fission once every 30 minutes. if you started with a culture containing 2 cells, how many would be present after 2 hours?
Answers
After 2 hours, there would be 20 cells present in the bacterial culture, assuming ideal conditions and constant division rate of one division every 30 minutes.
The bacterial species in question divides by binary fission every 30 minutes. To determine how many cells would be present after 2 hours, we need to calculate the number of divisions that would occur during that time period.
Since the bacteria divide every 30 minutes, we can divide the total time period of 2 hours (120 minutes) by the time it takes for one division (30 minutes). This gives us 120/30 = 4 divisions.
Starting with a culture containing 2 cells, each division results in the formation of 2 new cells. So, after the first division, we have 2 + 2 = 4 cells. After the second division, we have 4 + 2 + 2 = 8 cells. After the third division, we have 8 + 2 + 2 + 2 = 14 cells. And after the fourth division, we have 14 + 2 + 2 + 2 + 2 = 20 cells.
Therefore, after 2 hours, there would be 20 cells present in the culture.
In summary,
1st division: 2 cells + 2 new cells = 4 cells
2nd division: 4 cells + 2 new cells = 6 cells
3rd division: 6 cells + 2 new cells = 8 cells
4th division: 8 cells + 2 new cells = 10 cells
Hence, after 2 hours, there would be a total of 20 cells present in the culture.
It's important to note that this calculation assumes ideal conditions, where each division occurs with perfect accuracy and there are no factors affecting bacterial growth or death. Additionally, the calculation assumes that the cells have enough resources to sustain division at a constant rate. In real-world scenarios, these conditions may vary and affect the actual growth rate of the bacteria.

Why does a light go out when you turn off the wall switch?
The switch changes the direction of the flow of electrons.
The switch absorbs the electrical energy.
The switch causes a break in the circuit.
The switch changes the circuit from series to parallel.
Answers
"The switch causes a break in the circuit" when you turn off the wall switch and causes the light to go out. The correct option is C.
When you turn off the wall switch, it interrupts the flow of electricity in the circuit, which causes the light to go out. The wall switch controls whether the circuit is in series or parallel.
In a series circuit, the components are connected in a single path, which means that the current must flow through each component in turn. When the switch is turned off, the circuit is broken and the flow of electricity is interrupted, causing the light to go out.
In a parallel circuit, the components are connected in multiple paths, which means that the current can flow through one path even if another path is interrupted. If the light is part of a parallel circuit, turning off the switch may not cause it to go out immediately, since the current can still flow through the other components in the circuit. However, if all the paths in the parallel circuit are interrupted, the light will go out.
Therefore, the correct answer is option C.

A soccer ball is kicked upward from a height of 6 ft with an initial velocity of 96 ft/s. How high will it go? Use -32 ft/s? forthe acceleration caused by gravity. Ignore air resistance.
Answers
Given,
The initial height of the soccer ball, h₁=6 ft
The initial velocity of the ball, u=96 ft/s
The acceleration due to gravity, g=-32 ft/s
When the ball reaches the maximum height, its velocity will reduce to zero.
Thus the velocity of the ball when it is at its maximum height is v=0 ft/s
From the equation of motion,
\(v^2-u^2=2gh_2\)Where h₂ is the total height covered by the ball from its initial height to reach its maximum height.
On substituting the known values,
\(\begin{gathered} 0-96^2=2\times-32\times h_2 \\ \Rightarrow h_2=\frac{-96^2}{2\times-32} \\ =144\text{ ft} \end{gathered}\)Thus the maximum height reached by the ball is,
\(\begin{gathered} H=h_1+h_2 \\ =6+144 \\ =150\text{ ft} \end{gathered}\)Thus the maximum height reached by the ball is 150 ft.

with what constant velocity does an object of mass 5kg move if it’s momentum is 10kg•m/s?
Answers
The object would be moving at a constant velocity of 2 m/s.
A vector number called velocity is used to explain how quickly an object's position changes in relation to time. It is stated in terms of metres per second (m/s) or kilometers per hour (km/h), and is defined as the displacement (change in position) of an object divided by the time interval during which the displacement occurred.
The momentum (p) of an object is defined as the product of its mass (m) and velocity (v):
p = mv
We can rearrange this equation to solve for velocity:
v = p / m
Substituting the given values, we get:
v = 10 kg.m/s / 5 kg
Simplifying the expression, we get:
v = 2 m/s
Therefore, the object is moving at a constant velocity of 2 m/s.

Imagine that you are hovering next to a space shuttle and your buddy of equal mass who is moving a 4km/h with respect to the ship bumps into you if he holds onto you how fast do you both move with respect to the ship
Answers
The two individuals will move together with a velocity of -2 km/h.
What is the common velocity after the collision?Assuming that the initial velocity of the space shuttle is zero, and neglecting the effect of gravity, the total momentum of the system before the collision is zero, since the space shuttle and the two individuals are at rest. After the collision, the momentum of the system must still be zero, since there are no external forces acting on it.
If your buddy bumps into you and holds onto you, the two of you will move together with a common velocity.
Since your buddy has a velocity of 4 km/h with respect to the ship, the momentum of your buddy before the collision is:
momentum = mass x velocity = m x v = m x 4 km/h
To conserve momentum, the momentum of the two individuals after the collision must also be equal to m x (-4 km/h), since the momentum is opposite in direction.
Since the two individuals have the same mass, their common velocity after the collision can be calculated as:
momentum = mass x velocity = 2m x v'
where;
v' is the common velocity of the two individuals after the collision.Therefore:
2m x v' = m x (-4 km/h)

in a closed container filled with gas, what happens to the pressure as the volume of the container increases?
Answers
According to Boyle's Law, as the volume of a closed container filled with gas increases, the pressure will decrease.
According to Boyle's Law, which describes the relationship between the pressure and volume of a gas at constant temperature, the pressure of a gas will decrease as the volume of the container increases, assuming the amount of gas and temperature remain constant.
Boyle's law can be stated mathematically as:
P1 × V1 = P2 × V2
where:
P1 and V1 = initial pressure and volume of the gas
P2 and V2 = final pressure and volume of the gas.
As the volume increases (V2 > V1), the equation shows that the pressure (P2) must decrease to maintain the equality. In other words, if the volume of the container increases, the pressure will be decreased, assuming the temperature and the amount of gas remain constant.

Calculate; 1. The angular velocity of the turntable. 2.The or angular acceleration ot the turntable. 3.The torque on the grammaphone record 4. the rotational kinetic energy. 5. work done by the torque in 0.2s
Answers
The angular velocity of the turntable is 4.19 radians/second . The angular accelatation of the turntable is 8.38 radians/second².
The torque on the grammaphone record is 0.0419 Nm. The rotational kinetic energy is 0.0439 J. . The work done by the torque in 0.2 s is 0.00702 J.
How to find the work done?The turntable has a uniform angular velocity of 40 rounds per minute. To convert this to radians per second, we can use the following conversion factors:
1 round = 2π radians (since there are 2π radians in a complete circle)
1 minute = 60 seconds
So, the angular velocity (ω) can be calculated as:
ω = 40 rounds/minute × (2π radians/round) × (1 minute/60 seconds)
ω ≈ 4.19 radians/second
The record accelerates uniformly to the angular velocity of the turntable in 0.5 seconds. Let's denote the angular acceleration as α. We can use the formula:
ω = ω₀ + αt
Plugging in the values, we get:
4.19 = 0 + α(0.5)
α = 4.19 / 0.5
α ≈ 8.38 radians/second²
The moment of inertia of the grammaphone record (I) is given as 5.0 x 10^(-3) kgm². We can use the formula:
τ = Iα
Plugging in the values, we get:
τ = (5.0 x 10^(-3)) x 8.38
τ ≈ 0.0419 Nm
The rotational kinetic energy (K) can be calculated using the formula:
K = 0.5 * I x ω²
Plugging in the values, we get:
K = 0.5 * (5.0 x 10^(-3)) * (4.19)²
K ≈ 0.0439 J
The work done (W) by the torque can be calculated using the formula:
W = τ * θ
Plugging in the values for α and t = 0.2s, we get:
θ ≈ 0.5 * 8.38 * (0.2)²
θ ≈ 0.1676 radians
Now, we can calculate the work done:
W = 0.0419 * 0.1676
