Explanation:
- During a certain period, the angular position of a rotating object is given by: = − + , where is in radian and t is in seconds. Determine the angular position, angular speed, and angular acceleration of the rotating object at = Sec.
The question is not complete. The complete question is :
During a certain period of time, the angular position of a rotating object is given by [tex]$\theta =2t^2 +10t+5$[/tex], where θ is in radians and t is in seconds. Determine the angular position, angular speed, and angular acceleration of the door (a) at t = 0.00 seconds, (b) at t = 3.00 seconds.
Solution :
Given :
Displacement or angular position of the object, [tex]$\theta =2t^2 +10t+5$[/tex]
∴ Angular speed is [tex]$\omega = \frac{d \theta}{dt}$[/tex]
ω = 10 + 4t
And angular acceleration is [tex]$\alpha = \frac{d \omega}{dt}$[/tex]
α = 4
a). At time, t = 0.00 seconds :
Angular displacement is [tex]$\theta =2t^2 +10t+5$[/tex]
[tex]$\theta =2(0)^2 +10(0)+5$[/tex]
= 5 rad
Angular speed is ω = 10 + 4t
ω = 10 + 4(0)
= 10 rad/s
Angular acceleration is α = 4 [tex]$rad/s^2$[/tex]
b). At time, t = 3.00 seconds :
Angular displacement is [tex]$\theta =2t^2 +10t+5$[/tex]
[tex]$\theta =2(3)^2 +10(3)+5$[/tex]
= 53 rad
Angular speed is ω = 10 + 4t
ω = 10 + 4(3)
= 22 rad/s
Angular acceleration is α = 4 [tex]$rad/s^2$[/tex]

The statement explains the importance of enzymes that check for and repair mistakes during DNA replication is the enzymes prevent many genetic mutations from being expressed. Thus, the option C is correct.
What is RNA polymerase?RNA polymerase is an enzyme that aids in the transcription of DNA into RNA during transcript in the nucleus. The enzymes prevent many genetic mutations from being expressed.
Primase is an enzyme that synthesizes short RNA sequences called primers. These primers serve as a starting point for DNA synthesis during replication as the DNA polymerases cannot begin the synthesis of the new strand, they only extend it after primase begins it and primase produces RNA molecules, the enzyme can be said to be a type of RNA polymerase.
Therefore, The statement explains the importance of enzymes that check for and repair mistakes during DNA replication is the enzymes prevent many genetic mutations from being expressed. Thus, the option C is correct.

what is it called when a magnet causes the atoms in a non-magnetic metal to line up and act like a magnet?
a: oriented magnet
b: permanent magnet
c: non-magnet
d: induced magnet
Answer:
I think It's induced magnet
Explanation:
Because a magnet and non magnet can be chicken nuggets
If a magnet causes the atoms in a non-magnetic metal to line up and act like a magnet, the non magnet is said to be an induced magnet by the magnetic induction by a permanent magnet.
What is magnetic induction ?A permanent magnet is made of ferromagnetic materials which are having permanent magnetic properties. The magnetic field lines from permanent magnet always align with an applied magnet.
As in the case of dipole molecules capable of inducing a polarity to a nonpolar molecule, a magnetic field by a strong magnet can induce a magnetic property to a nonmagnet.
The induced magnetic field only reside in the object as long as the induction source is there. For example the a rotating electric filed causes magnetic moment in a nonmagnet.

Answer:
True
Explanation:
The object is at rest, which means it's not moving, so there is no net force on it, according to Newton's First Law.
Why do these two magnets attract each other?
A. The poles that face each other are opposite magnetic poles.
B. The poles of one magnet cause the other magnet to have a
magnetic field.
C. The magnetic fields leave the magnets and concentrate between
them.
D. The magnetic field is weaker between the two magnets.
Answer:
A
Explanation:
When two magnets are brought near each other, like poles repel; opposite poles attract. We like to represent this force effect of a magnet on iron-like objects with a concept called magnetic field. The concept of field can be best understood if we remember the gravitational force of Earth on object near it.
Every magnet has two poles. The same pole repels while opposite poles attract each other. Option (A) is correct. The poles that face each other are opposite magnetic poles.
What is a magnet?A magnet is a substance or item that generates a magnetic field. This magnetic field is invisible, but it is responsible for a magnet's most remarkable property.
A force that attracts or repels other ferromagnetic elements such as iron. Every magnet has two poles. The same pole repels while opposite poles attract each other.
Due to polarity Option (A) is correct. Hence the poles that face each other are opposite magnetic poles.

Shows a car travelling around a bend in the road. The car is travelling at a constant speed. There is a resultant force acting on the car. This resultant force is called the centripetal force. (i) In which direction, A, B, C or D, does the centripetal force act on the car? Tick ( ) one box. A B C D (1) (ii) State the name of the force that provides the centripetal force.
Answer:
This question is incomplete
Explanation:
This question is incomplete but the missing figure is in the attachment below.
When an object is travelling around a circular path, there is a force that tends to draw that object towards the center of the circular path and keep the object moving in the curved path, that force is called the centripetal force. From this description, it can be deduced that the direction of the centripetal force that acts on the car (in the attachment below) is D.
The name of the force that provides this centripetal force is frictional force. This is the force that prevents the car from slipping off the road; keeping it moving in the curved path.
what is it that makes a magnet different from a piece of iron that is not mangetic?
Answer:
Under normal conditions, a magnetic material like iron doesn't behave like a magnet because the domains don't have a preferred direction of alignment. On the other hand, the domains of a magnet (or a magnetized iron) are all aligned in s specific direction.

Assuming that it could maintain the same acceleration at higher speeds, how long would it take the car to go from 0 to 120 mph
The question is incomplete, the complete question is;
A car can go from 0 to 60 mph in 7.0 s. Assuming that it could maintain the same acceleration at higher speeds, how long would it take the car to go from 0 to 120 mph? A. 10 s B. 14 s C. 21 s D. 28 s
Answer:
B
Explanation:
We have;
vo = 0 m/s
v1 = 60 mph or 26.8 m/s
v2 = 120 mph or 53.6 m/s
t1 = 7s
To obtain a
v1 = vo + at1
but vo = 0 m/s
a = v1/t1 = 26.8 m/s/7s = 3.8 ms-2
To obtain t2 for the car;
v2 = vo + at2
but vo = 0 m/s
t2= v2/a = 53.6m/s/3.8ms-2
t2 = 14.1 s

Section 1: Experimental Overview
Use your answers from questions 1-3 as the basis for the first section of your lab report. This section provides your reader with background information about why you conducted this experiment and how it was completed. Outline the steps of the procedure in full sentences. It also provides potential answers (your hypothesis/es) relative to what you expected the experiment to demonstrate. This section should be 1-3 paragraphs in length.
Answer:
1-state what the lab is about, that is, what scientific concept (theory, principle, procedure, etc.) you are supposed to be learning about by doing the lab. You should do this briefly, in a sentence or two. If you are having trouble writing the opening sentence of the report, you can try something like: "This laboratory experiment focuses on X…"; "This lab is designed to help students learn about, observe, or investigate, X…." Or begin with a definition of the scientific concept: "X is a theory that…."
2-give the necessary background for the scientific concept by telling what you know about it (the main references you can use are the lab manual, the textbook, lecture notes, and other sources recommended by the lab manual or lab instructor; in more advanced labs you may also be expected to cite the findings of previous scientific studies related to the lab). In relatively simple labs you can do this in a paragraph following the initial statement of the learning context. But in more complex labs, the background may require more paragraphs.
