Answer:
0. 174 A
Explanation:
This is similar to your other question
[tex]\boxed{\mathfrak{Power(P)=Voltage(V) \times Current(I)}}[/tex]
Voltage (V) = 230 VPower (P) = 40 W=> 40 = 230 × I
=> [tex]\mathsf{I=\frac{40}{230} }[/tex]
=> I = [tex]\mathsf{\frac{4}{23} }[/tex]
=> I = 0.174 A
I is the current, the computer draws when connected to a 230 V mains supply, and it's SI unit is Amperes.

The graph in Figure 4.15 shows the position and time for two runners in a race. Who has the faster speed, Robin or Joel? Explain how to answer this question without doing calculations.
Answer:
Joel has the faster speed.
Explanation:
Joel has a steeper slope on the graph. The steeper a slope is, the faster speed will be. Therefore, Joel's slope is steeper which increases overall speed.
What does Newton's Second Law state and what are the formulas used?
Answer:
Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

write 9.423 x 10^-9 in expanded form
Answer:
Very large and very small numbers written in standard form take up a large amount of space. They are hard to read and understand and are difficult to use in mathematics. One way to write a very large or very small number is to use a different form of notation. Converting to a workable number is done using scientific or engineering notation.
Explanation:
find the components to write this vector in unit vector notation: 63.5 A please help
Vector is perpendicular to x axis or i component.
Hence i component is 0
j component is 63.5
[tex]\\ \sf\longmapsto \overrightharpoon{A}=0\hat{i} +63.5\hat{j}[/tex]

If an object falls far enough, it will reach terminal velocity. At this velocity, the force of air
resistance is equal to the force of gravity on the object. The forces on the falling object are
balanced. What will happen to the object and why?
Answer:
The object will contine to fall, but at a constant velocity. There will be no more acceleration.
Explanation: When the force of gravity is equal to the reverse force of air resistance, there will will be no net force on the falling obect. F = ma, and F (net) = 0. It will continue at the same speed until those forces become imbalanced again (such as when the force pushing up from the ground is greater than the force of gravity pulling it down). The metric term for this sudden resistance is "crash/bang/clunk/yieouch."
If you wanted to find an element that
would react similarly to chlorine (CI),
where would you look and why?
Answer: Fluorine (F) and chlorine (Cl) are two good choices. See reasoning below.
Explanation: Mendeleev arranged the elements in the periodic table in a manner that each group, or vertical column, contained elements that exhibited similar chemical properities. He even reserved spaces for undiscovered elements when none of the known elements had properties similar to those above or below the known elements in a group. An interesting event illustrates this property. In December 2010, NASA announced an important new discovery that was to be broadcast on live TV, creating much speculation (e.g., UFO's are real and we'll see the aliens sequestered at Roswell!!! I knew it.).
The actual announcement:
"Dec. 2, 2010: NASA-supported researchers have discovered the first known microorganism on Earth able to thrive and reproduce using the toxic chemical arsenic. The microorganism, which lives in California's Mono Lake, substitutes arsenic for phosphorus in the backbone of its DNA and other cellular components."
A look at the periodic table shows arsenic just below phosphorus, in the same group. This was an unexpected find, but it might have been predicted with an understanding of how the elements are organized.

Question 8 of 35
A car has a mass of 1000 kg and is travelling at a speed of 26 m/s. Calculate the kinetic energy of the
car. Use the word equation below to help you.
kinetic energy = 0.5 x mass x (speed)?
Answer:
338,000 JExplanation:
The kinetic energy of an object can be found by using the formula
[tex]k = \frac{1}{2} m {v}^{2} \\[/tex]
m is the mass
v is the velocity
From the question we have
[tex]k = \frac{1}{2} \times 1000 \times {26}^{2} \\ = 500 \times 676 \\ = 338000[/tex]
We have the final answer as
338,000 JHope this helps you

A car is towing a boat on a trailer. The driver starts from rest and accelerates to a velocity of 11 m/s in a time of 28 s. The combined mass of the boat and trailer is 410 kg. The frictional force acting on the trailer can be ignored. What is the tension in the hitch that connects the trailer to the car
The tension on the hitch that connects the trailer to the car is 160 N.
From the information provided;
Initial velocity = 0 m/s (the car started from rest)
Final velocity = 11 m/s
Time taken = 28 s
From the formula;
a = v - u/t
a = 11 - 0/28 = 0.39 ms-2
The force that acts on the trailer = tension in the hitch that connects the trailer to the car
Force = mass × acceleration
Force = 410 kg × 0.39 ms-2
Force = 160 N

The precision of a balance is ±0.02 g. The accepted value for a measurement is 26.86 g. Which measurement is in the accepted range?
26.02 g
26.82 g
26.87 g
26.90 g
Explanation:
The precision of a balance is ±0.02 g.
The accepted value for a measurement is 26.86 g.
The accepted range is: =[26.86-0.02, 26.86+0.02] = [26.84, 26.88]So,26.87 g is correct

atoms and molecules in matter are always_______
I think atoms and molecules in matter are always in motion because of kinetic energy.
Answer:
in motion.
Explanation:
In chemistry, we often explain the states of matter in terms of the kinetic molecular theory (KMT). The word kinetic refers to motion and the kinetic molecular theory suggests that atoms and molecules are always in motion. The energy associated with this motion is termed kinetic energy.
Point out the following about solids: The particles (atoms or molecules) are attracted to each other. The particles (atoms or molecules) vibrate but do not move past one another. The solid retains its shape.
They are not always in motion. They are always in motion if and only if the temperature of the surroundings is greater than absolute zero ( 0 K ).
Not only are molecules really small but they are in constant motion. The motion is called “thermal motion” because it's caused by temperature. Increase the temperature around them and the molecules move faster.
