Answer:

The correct option is C

Explanation:

No. 1 is not true because a Permanent magnet DC motor is also one of the main types of DC motors. A DC motor is any of a class of motors that converts direct current electrical energy into mechanical energy.

Answer:

<em>C) only No. 2 is true.</em>

Explanation:

There are actually 4 main types of DC motors. Namely Series, Shunt, and Compound and Permanent Magnet DC Motors.

The permanent motor magnet requires a permanent magnet to generate flux of field. This form of DC motor offers excellent initial torque and strong speed control, however power is restricted so they are usually used in applications with low horsepower rates.

A police officer is called to the scene of a car accident in his accident he sketches the scene and describes it according to hi
abruzzese [7]

Answer:

The driver was not telling the truth because it is not possible for a car to hit another car from behind and generate a force to the sides that deflects it from its path.

Explanation:

First, we analyze the driver's statement.

The driver when arriving at the curve, is collided from behind by another car and deviates from his path and crashes into a tree. For the car to go to the tree there must be a force towards the tree.

The net force that causes the car to deviate must be formed by the sum of the motion vector of the first car plus the force that is directed towards the tree.

Here we verify that a car hitting from behind will not generate a force to the sides, but will generate a force in the same direction that the car moves, forward.

1. a=Δv/Δt=(v-vo)/t=(0-25)/5=-25/5=-5 m/s²

The "-" sign shows us that the car has a slow motion


2.a=Δv/Δt=(v-vo)/t=(10-0)/4=10/4=2,5 m/s²


3.they do not have acceleration because they go at constant speed

How many leptons are in ⁷₃Li?
shutvik [7]

-- Electrons are leptons.  There are <em>three</em> electrons in each neutral Lithium atom.

The last two parts of the question are absurd.

-- Bonbons are candy, not atomic particles.  A bonbon cannot fit into a Lithium atom.

-- A pentagon is a closed geometric figure that has five sides.  Although you could, in principle, have a pentagon small enough to fit into a Lithium atom, you could never find a piece of paper small enough to draw it on.
