A device that uses electricity and magnetism to create motion is called a _________motor,magnet,generator . In a reverse process, a device that uses motion and magnetism can be used to create ________ light,electromagnetism,electricity
Answers
Answer:
1. motor
2. electricity
Explanation:
A motor uses electromagnetism or electricity and magnetism to create motion. A motor converts electric energy into mechanical energy.
On the other hand, the reverse process of using motion and magnetism will create electricty. It will convert the mechanical energy to electrical energy. And the machine that does it is called a generator.
In short, 1st Blank = Motor
2nd Blank = Electromagnetism
Hope this helps!

Final answer:
The last and longest manned mission to Skylab is a notable point in history of space exploration, but the specific duration is not stated in the provided references.
Explanation:
In regard to the question, "What was the duration of the last and longest manned mission to Skylab?", the Skylab missions were part of a significant chapter in U.S. space exploration history during the 1970s. However, the provided reference material does not offer specific information about the duration of the last and longest manned mission to Skylab. Skylab was an important part of American space research, serving as a space station where numerous scientific experiments were conducted. Yet, without the specific details, it is difficult to provide an accurate response to this particular query. The Skylab program, operated by NASA in the 1970s, had its last and longest manned mission known as Skylab 4. The Skylab 4 mission launched on November 16, 1973, and lasted for a total of 84 days, with the crew returning to Earth on February 8, 1974. The crew consisted of Gerald Carr, Edward Gibson, and William Pogue. This mission set a record for the longest manned spaceflight at that time, spending an extended period aboard the Skylab space station for scientific research and experiments.

The current is reduced as less energy is available to move electrons through the wire.
This is because electrons moving through the conducting substance collide with the electrons and ions.
This causes collisions which further more convert kinetic energy into thermal energy because of the fewer energy that is available, it reduces.
Moreover the resistivity factor of the conductor it self might play some role and the loss of energy too.

The child will be riding a bicycle at 3m/s after 4 seconds.
If you want a full equation (which you might not):
let a be acceleration rate, Vf be final velocity, Vi as initial velocity, and t as time.
a = (Vf - Vi)/t
let's fill in everything we know now:
-3 = (Vf - 15)/4
now let's solve for Vf
-3 = Vf/4 - 15/4
-Vf/4 = 3 - 15/4
Vf/4 = -3 + 15/4
Vf = -12 + 15
Vf = 3
Therefore, final velocity is 3m/

The option that best describes the difference between speed and acceleration is : ( B ) Speed is the distance an object travels within a specific unit of time, whereas acceleration is the rate at which the speed or direction of an object is changing.
Difference between and Acceleration and Speed
Acceleration is the rate of change of velocity with time while speed is the rate of change distance with time.
Acceleration is a vector quantity because it has magnitude and direction while speed is a scalar quantity.
Hence we conclude that Speed is the distance an object travels within a specific unit of time, whereas acceleration is the rate at which the speed or direction of an object is changing.
