3. How long (means time) must a 400 W electrical engine work in order to produce 300 kJ of work? (p = W/t. T = w/p)
Answer:
7.5 sec
Explanation:
400 • t = 3000
(the 300 kJ was turned into 3000 J)
divide both sides by 400
400t/400 = 3000/400 ——-> 7.5
The answer becomes 7.5 sec

A country creates a park to protect a forest, what type of resource?
A truck covers a distance of 360 km in 5 hrs. Find its speed
Answer:
72 km / hour
Explanation:
Speed equals to distance over time. We are given distance equal 360 km and time in 5 hours.
Hence:
[tex]\displaystyle \large{s=\frac{360}{5}}\\\displaystyle \large{s=72}[/tex]
Therefore, the speed is 72 km / hour.
Notes
Sometimes, speed is defined as ‘v’ while velocity is defined as ‘v vector’ indicating that velocity is speed with direction and speed is just velocity with only magnitude.

Which is an example of current electricity
Answer:
A or B you choose
Explanation:
This is called current electricity or an electric current. A lightning bolt is one example of an electric current, although it does not last very long. Electric currents are also involved in powering all the electrical appliances that you use, from washing machines to flashlights and from telephones to MP3 players.
what is an electrical current, amp, ampere Current is the flow of electrons. When a circuit is closed then a current of electrons can flow and when a circuit is open then no current can flow. We can measure the flow of electrons just like you can measure the flow of water through a pipe.
High energetic winds turning generator , causing electrons to flow into power lines is an example of current electricity. Remaining all are examples of static electricity .
What is current electricity ?The movement of electrons from one area of the circuit to another is referred to as current electricity. Free electrons flow between two points when two bodies with different potentials are connected by a wire, until both objects reach the same potential, at which point the current stops.
Current flows until a potential difference exists throughout the conductor. The following techniques can be used to produce current electricity:
1. Through the passage of a metal wire through a magnetic field (Both alternating current and direct current can be generated by the following method)
2.Utilizing a battery and chemical reactions (Direct current can be generated through this method)
Here, the wind's kinetic energy provide the mechanical energy for the generator to to produce power lines. Hence option A is correct. All others are static electricity for short time only.

Describe the rise and fall of a basketball using the concepts of kinetic energy and potential energy.
Answer:
in the beginning the kinetic energy is at a maximum level because the starting velocity is high comparatively.. and because of the gravitational acceleration acting on the ball in the opposite direction the kinetic energy drops proportionally because of the velocity drop. after the ball reaches it's maximum height the potential energy of the ball is high because of the height.. and again the kinetic energy starts to build because the ball again starts to fall down..

The summary identifies the location(s) in the electric field where the field strength is the greatest, explains how the electric field strength changes due to a change in position, describes the movements of both a positive and a negative test charge placed in the electric field, predicts how the electric field changes due to an increase and decrease in voltage, and predicts how the electric field changes due to an increase and decrease in the distance between leads.
(a) When the voltage increases, the electric field increases, and vice versa.
(b) When the distance of the charge increases, the electric field strength decreases, and vice versa.
Electric field directionThe direction of the electric field depends on the direction of the positive charge, electric field is always directed opposite to positive charge.
Relationship between electric field and voltageThe potential of a unit charge is the product of the electric field strength and the distance of the charge.
V = Ed
E = V/d
Thus, when the voltage increases, the electric field increases, and when the voltage decreases, the electric field decreases.
Also, when the distance of the charge increases, the electric field strength decreases, and the distance decreases, the electric field strength increases.

Which changes in an electric motor will make the motor stronger? select 3 options. using a stronger permanent magnet using a weaker permanent magnet increasing current in the electromagnet decreasing current in the electromagnet increasing the distance between the magnets decreasing the distance between the magnets
1. Using Strong Permanent. 2. increasing the current. 3. Decreasing the space between Magnets
Explanation:
Brainiest
The changes that make the motor stronger will be using strong permanent magnets, increasing the current, and decreasing the space between magnets.
What is an electric motor?An electric motor is a mechanism that turns electricity into mechanical energy.
The interaction between the motor's magnetic field and electric current in a wire winding generates force in the form of torque imparted to the motor's shaft in most electric motors.
An electric generator is physically equivalent to an electric motor, but it converts mechanical energy into electrical energy using a reversed flow of power.
When string magnets are used, a strong flux is produced, and the motor becomes more powerful. Internal flux has a significant impact on coil strength.
Increasing current results in greater power. In the same way, shortening the distance between magnets makes the motor stronger by increasing flux and torque.]
Hence the changes that make the motor stronger will be using strong permanent magnets, increasing the current, and decreasing the space between magnets.

A pool player makes a shot on a pool table. The 0.17 kg cue ball strikes the 0.15 kg #8-ball, but it is not sunken on the table. Instead, the 8-ball bounces off a rail, and collides into the cue ball a second time. When they collide in a perfectly elastic collision, the cue ball is travelling 1.2 m/s [N10°E) and the 8-ball is travelling 0.89 m/s [W20°N]. Determine the final velocities of each ball.
Answer:
cue ball final: 0.85 m/s at N65°W
8-ball final: 1.27 m/s at N12°E
Explanation:
In a perfectly elastic collision, both momentum and energy are conserved. The momentum is the sum of products of mass and velocity. The energy is half the product of mass and the square of velocity. The difference of "particle" velocities changes sign as a consequence of the collision.
