You are asked to contemplate the concepts of oscillation and periodic motion (or periodic behavior). These lead to the definition of a special kind of periodic motion called simple harmonic motion. For now, let's just think about periodicity (1) and oscillations for the following two scenarios. Your answers will not be marked for correctness. Scenario 1: The motion of the second hand on a clock is:_______ a. periodic but not oscillatory (I.e. the hand does not oscillate or undergo oscillations). b. periodic and also oscillatory. c. not periodic and not oscillatory. d. oscillatory but not periodic. Scenario 2: The motion of a person rocking back and forth on a rocking chair to the beat of a song is:_______ a. periodic but not oscillatory. b. periodic and also oscillatory. c. not periodic and not oscillatory. d. oscillatory but not periodic. Please explain why your answers for the two scenarios are either the same or different. Your answer should include brief definitions of periodic and oscillatory (or oscillations).

I believe the correct answer from the choices listed above is the last option. A current carrying wire wrapped around an iron ore is called an electromagnet. They are usually consist of a large number of closely spaced turns of wire that create the magnetic field. Hope this answers the question.

Research indicates that inattentional blindness often decreases when people work on tasks that require a great deal of attention. Please select the best answer from the choices provided T F

Answers

Answer:

False

Explanation:

Inattentionla blindness is a condition that happens when you overview or do not notice an object that is not supposed to be in a certain place and that is strange for its context because you are paying attention to something else, this means that if you do a task that needs a great deal of attention you will actually increase the inattentional blindness.

The correct answer is F

A 1000-kg car is moving along a straight road down a 30∘ slope at a constant speed of 20.0m/s. What is the net force acting on the car?

Answers

Answer:

net force acting on the car is zero

Explanation:

given data

mass of car = 1000 kg

slope = 30°

constant speed = 20.0 m/s

to find out

net force acting on the car

solution

we know here that car is moving with given 20 m/s velocity so here net force acting on the car will be zero

as net force is express as

Force = mass ×  acceleration    .....................1

and here acceleration is change of velocity per change in time

and here change in velocity is 0  

so that net force will be zero

so net force acting on the car is zero

Final answer:

In this scenario, the car is moving at a constant speed down a slope, which according to Newton's first law of motion, means that the net force acting on the car is zero.

Explanation:

The key to figuring out this problem lies within understanding Newton's first law of motion which states that an object will stay in constant motion as long as the net force acting upon it is zero. In this case, the car is moving at a constant speed implying that the net force, or the sum of all forces acting on it, equals zero. As the car moves down a slope, there's the force of gravity pulling it downwards and the normal force from the road acting upwards. When the car moves in a constant speed, these two forces are balanced, making the net force zero (0 Newtons).

A force of 200 N is required to keep an object sliding at a constant speed of 2 m/s across a rough floor. How much power is being expended to maintain this motion?

Answers

Force x speed = power
200 x 2 = 400 watts

Answer:

Explanation:

Power = work/time

Work = force x distance

power = force X distance/time (velocity)

power = 200N x 2m/s

power = 400 joules
