My computer is powered by electrical energy from the wall outlet. Even if I happen to be running my computer on battery right now, the battery is just giving me energy that came from the wall outlet and got temporarily stored in the battery.

A car is traveling at 114 m/s and changes its velocity to 77 m/s in 9 sec.

suter [353]

Answer:

Given -

Initial Velocity, u = 114 m/s
Final velocity, v = 77 m/s.
Time taken, t = 9 sec.

To find - 

Acceleration of the car.

Solution -

Here, using the equation of motion v = u + at we can find the acceleration easily.

★ Here,

V = Final velocity
U = Initial Velocity
A = Acceleration
T = Time.

Substituting the values -

→ 77 = 114 + a(9)

→ 9a = 114 - 77

→ 9a = 37

→ a = 37/9

→ a = 4.1 m/s

Therefore, the acceleration of the car will be 4.1 m/s.

What is the function of the commutator in a DC motor? to spin the magnet to change direct current into alternating current to ch

Anestetic [448]

Commutator is an attachment, connected to the armature of motor or generator through which electrical connection is made and ensures that the current is flowing like a direct current
And it is a device for reversing the direction of flow of electrical current.
In addition by using induction the current is induced in a circuit due to a change or motion in a magnetic field is so directed as to oppose the change in flux "is the surface magnetic divided by time" and to exert a mechanical force opposing the motion of the spin of wire coil.

How is a front defined in terms of weather ?. A) the leading edge of an anticyclone flow. B) the trailing edge of a warm front.

Svetllana [295]

A front is defined as a "boundary" that separates two masses of different air densities. I am not entirely sure, but I think the answers are either C or D, but I'm mostly convinced it's option D.
