Based on the information, the net force acting on sphere B is 0 N.
How to calculate the valueNet force refers to the overall force acting on an object or system. It is determined by considering all the individual forces acting on the object and combining them according to their magnitudes and directions.
When multiple forces act on an object, they can either be in the same direction or in opposite directions. If the forces are in the same direction, the net force is equal to the sum of the individual forces.
The forces exerted by spheres X and Y on sphere B are equal in magnitude and opposite in direction. Therefore, they cancel each other out and the net force on sphere B is 0 N.
F(BX) = F(BY) = 6.0 × 10^-6 N
F(net) = F(BX) + F(BY) = 0 N

what is the pressure of a tank of uniform cross sectional area 4.0m2 when the tank is filled with water a depth of 6m when given that 1 atm=1.013 x 10^5pa density of water=1000kgm-3 g=9.8m/s2
The pressure of the tank, when filled with water at a depth of 6 m, is approximately 580.124 atmospheres (atm). To calculate the pressure of the tank, one can use the equation: Pressure (P) = Density (ρ) × g × Depth (h)
Pressure (P) = Density (ρ) × g × Depth (h)
Given: Density of water (ρ) = 1000 kg/m³
Acceleration due to gravity (g) = 9.8 m/s²
Depth (h) = 6 m
Using the given values, one can calculate the pressure:
Pressure = 1000 kg/m³ × 9.8 m/s² × 6 m Pressure
= 58800 kg·m⁻¹·s⁻²
Now, let's convert the units to pascals (Pa) using the conversion 1 atm = 1.013 x [tex]10^5[/tex] Pa:
Pressure = 58800 kg·m⁻¹·s⁻² × (1 atm / 1.013 x[tex]10^5[/tex] Pa)
Pressure = 580.124 atm

when the trigger is pulled on a cordless drill it takes 0.36s for the drill bit to reach 5200rpm. If the drill spins counterclockwise then, what is the angular acceleration of the drill bit?
The angular acceleration of the drill is 1512.5 rad/s².
Time taken for the drill, t = 0.36 s
Angular velocity of the drill, ω = 5200 rpm = 544.5 rad/s
The change in angular velocity that a spinning object experiences per unit of time is expressed quantitatively as angular acceleration, also known as its rotational acceleration.
It is a vector quantity that has two distinct directions or senses as well as a component of magnitude. The unit of angular acceleration is rad/s².
So,
The expression for the angular acceleration is given by,
α = ω/t
α = 544.5/0.36
α = 1512.5 rad/s²

what is the pressure of a tank of uniform cross sectional area 4.0m2 when the tank is filled with water a depth of 6m when given that 1 atm=1.013 x 10^5pa density of water=1000kgm-3 g=9.8m/s2
The pressure of a tank of uniform cross-sectional area 4.0m2 when the tank is filled with water at a depth of 6m is 58800 Pa.
Pressure calculationTo find the pressure in the tank, we can use the formula for pressure:
Pressure = density x gravity x height
Density of water (ρ) = 1000 kg/m³
Acceleration due to gravity (g) = 9.8 m/s²
Height (h) = 6 m
Thus:
Pressure = 1000 kg/m³ x 9.8 m/s² x 6 m
Pressure = 58800 kg/(m·s²)
Since the unit of pressure is Pascal (Pa), which is equivalent to kg/(m·s²), the pressure in the tank is:
Pressure = 58800 Pa
Therefore, the pressure in the tank when it is filled with water to a depth of 6 m is 58800 Pascal.

The diagram shows the electric field due to point charge Q. The negative charge, A, is within the field. Charge Q has vectors radially inward starting perpendicular from the surface. The farther you get from the charge, the shorter the vectors. All vectors point towards the charge. A point labeled A is just to the right of the charged object. Which statements are correct? Check all that apply. Charge Q is positive. Charge Q is negative. The electric field is uniform. The electric field is nonuniform. If charge A is negative, it moves away from charge Q. If charge A is positive, it moves away from charge Q.
The correct statements are:Charge Q is positive, the electric field is nonuniform and if charge A is negative, it moves away from charge Q.
Based on the given information, we can make the following conclusions:
Charge Q is positive: The diagram shows that the electric field vectors point radially inward towards charge Q. Since like charges repel each other, for the vectors to point towards charge Q, it must be positive.
The electric field is nonuniform: The statement mentions that "the farther you get from the charge, the shorter the vectors." This implies that the magnitude of the electric field decreases with distance from charge Q. Therefore, the electric field is nonuniform.If charge A is negative, it moves away from charge Q: In the diagram, charge A is within the electric field of charge Q. Since opposite charges attract each other, if charge A is negative, it will experience a force that pulls it towards charge Q. Therefore, it will move towards charge Q, not away from it.
If charge A is positive, it moves away from charge Q: This statement is incorrect. According to the previous conclusion, if charge A is positive, it will experience a force that attracts it towards charge Q. Therefore, it will move towards charge Q, not away from it.
The provided information does not specify the behavior of charge A when it is positive. It is possible that charge A could move towards charge Q, or it could experience other forces depending on its position and the magnitude of the charges involved.

What is a benefit of using active solar energy over utility-scale solar energy for a home?
Installation costs are less with active solar systems.
Homeowner is not responsible for installation costs.
Energy comes from the active system, not a grid.
Homeowners will see less cost savings over time.
Using active solar energy for a home offers benefits such as lower installation costs, homeowner control over the system, reduced reliance on the grid, and potential cost savings over time. Option A
A) Installation costs are less with active solar systems: Active solar energy systems, such as solar panels or solar water heaters, can be installed directly on the home or property, eliminating the need for extensive infrastructure development associated with utility-scale solar energy projects.
B) Homeowner is not responsible for installation costs: While utility-scale solar energy projects may require homeowners to bear the costs of installation and infrastructure development, active solar systems for homes typically allow homeowners to directly invest in their own renewable energy solutions.
This means that homeowners have control over the installation process and can choose the system that best fits their budget and energy needs.
C) Energy comes from the active system, not a grid: Active solar systems for homes generate energy on-site using sunlight, allowing homeowners to reduce their reliance on the traditional power grid.
This independence from the grid provides benefits such as energy self-sufficiency, reduced vulnerability to power outages, and potential savings on utility bills. It also allows homeowners to have a direct and tangible impact on reducing their carbon footprint.
D) Homeowners will see less cost savings over time: This statement is incorrect. Over time, homeowners who invest in active solar energy systems can potentially experience significant cost savings. By generating their own renewable energy, homeowners can reduce their reliance on electricity provided by the utility company, which often comes with rising costs.
As utility rates increase, the savings from generating solar energy can become more substantial, allowing homeowners to recoup their initial investment and potentially even earn credits through net metering programs.
In summary, using active solar energy for a home offers benefits such as lower installation costs, homeowner control over the system, reduced reliance on the grid, and potential cost savings over time. These advantages make it an attractive option for homeowners seeking to embrace renewable energy and reduce their environmental impact. Option A
