Which refers to the ends of a magnet where the forces are strongest?
A) attracting forces
B) opposing forces
C) magnetic fields
D) magnetic poles
A material that produces magnetic field are called magnets. Magnetic poles refers to the ends of a magnet where the forces are strongest.
What are magnetic poles?Magnetic poles are the regions at each end of a magnet where the external magnetic field is strongest.
A bar magnet suspended in the Earth's magnetic field orients itself north-south. A north magnetic pole is the north-seeking pole of such a magnet or any similar pole.
Thus, the correct option is D.

TRUE or FALSE? If a moving object experiences an unbalanced force, then the
object will have an acceleration that is in the same direction as the unbalanced
force.
True I guess
because if the force is balanced and there is no net force, the object will not accelerate and the velocity will remain constant...

Plz help me. I need urgent Why a magnetic compass is used to determine direction? Why a nail gets magnetized when kept close to magnet? Why two pins get attracted by bar magnet maintain distance between ends?
Answer:
Compasses are mainly used in navigation to find direction on the earth. This works because the Earth itself has a magnetic field which is similar to that of a bar magnet. The compass needle aligns with the Earth's magnetic field direction and points north-south. Also, In a magnet all the domains are oriented in the same direction. In the case of a nail, the domains can be aligned in the same direction causing the nail to become magnetic. That is because if you hang a bar magnet from a thread, the north pole will point to magnetic north. When you bring one north pole close to another north pole they repel each other. You can feel the two magnets pushing each other apart.
Find the velocity of a ball traveling 5 meters for 20 seconds.
Formula:
Substitute:
Solution:
Answer:
The answer is
0.25 m/sExplanation:
The velocity of w given body given the distance and time taken can be found by using the formula
[tex]velocity = \frac{distance}{time} \\ [/tex]
From the question
distance = 5 m
time = 20 s
The velocity of the ball is
[tex]velocity = \frac{5}{20} = \frac{1}{4} \\ [/tex]
We have the final answer as
0.25 m/sHope this helps you
Formula: v = d/t
v = velocity
d = distance
t = time
We are given the distance (5 meters) and the time (20 seconds). Solve with these given values.
v = 5/20
v = 1/4 m/s
Best of Luck!

An ant is Dragging a Housefly and Elephant is pushing a big tree which is not moving. who is doing work? The ant or the elephant? Justify Your Answer!
Answer:
the ant
Explanation:
because work is done when there will be involvement of displacement in the direction of the force.
Answer:
The ant is doing work but the elephant is not
Explanation:
Work done = Force × Displacement
In case of ant and housefly,
Ants are dragging the housefly , so they are displacing the housefly from one point to the other by applying certain force , so we can say that they are doing work
In case of elephant and tree,
When the elephant is pushing the tree( applying force) , the tree is not moving which means that there is no Displacement, so work done will be
Work done = Force × Displacement
= Force × 0
= 0
The results of a dart game were precise but not accurate. The accepted value of the game was the center of the dartboard. Which correctly describes the results? All of the darts hit the center of the board. Some of the darts hit the center of the board. The darts hit the same general area of the board. The darts hit very different areas of the board.
Answer:
The darts hit very different areas of the board.
Explanation:
The bullseye is the point at which darts are most accurate. There is no accuracy nor precision if the darts are neither close to the target nor to one another.
What is dart precision?The degree of similarity between several measurements is known as precision.
Even if the measurements are not exactly the right value, they are very reproducible.
Throwing darts at a dartboard can be used to demonstrate accuracy and precision.
There is precision but not accuracy if every dart lands distant from the bulls-eye but extremely closely spaced apart.
In contrast to a dart that lands far from the bulls-eye, which shows poor accuracy, a dart that hits the bulls-eye is very accurate.
Therefore, The board was struck by the darts in a variety of ways.

If a bullet with an acceleration of 1.5 m/s2 takes 2 seconds to leave the muzzle of a rifle (starts at rest), what was the length of the rifles barrel?
Answer:
The length is [tex]D =3 \ m [/tex]
Explanation:
The velocity of the bullet is mathematically evaluated as
[tex]v = a * t [/tex]
=> [tex]v = 1.5 * 2 [/tex]
=> [tex]v = 3 \ m/s [/tex]
Now from kinematic equation
[tex]v^2 = u^2 + 2* a * D[/tex]
Here D is the length of the barrel and u = 0 m/s
So
[tex]3^2 = 0 + 2* 1.5 * D[/tex]
[tex]D = \frac{9}{3} [/tex]
[tex]D =3 \ m [/tex]
(USE THE GRAPH) Vectors B and C and are shown in the graph. Vector B is multiplied by the scalar 92. What angle does the new vector make with the x-axis?
Answer:
The angle the new vector makes with the x-axis is 33°
Explanation:
By multiplying a vector with a scalar, we multiply the similar components of the two quantities which is the magnitude of the scalar quantity and the magnitude of the vector with the new vector formed will have a magnitude equal to the product of the two magnitudes and the same direction of the original vector as follows;
The magnitude of the vector B = 5.6
The magnitude of the scalar = 92
The product of the two magnitudes = 5.6 × 92 = 515.2
The magnitude of the new vector = 515.2
The direction of the new vector = 33° South of West
Therefore, the angle the new vector makes with the x-axis = 33°.
The fastest helicopter, the Westland Lynx, can travel 3.33 km in the forward direction in just 30.0 s. What is the average velocity of this helicopter? Express your answer in both m/s and km/hr.
Answer:
The value in m/s [tex]v_{a} = 111 \ m/s [/tex]
The value in km/h [tex]v_{a} = 400\ km/h [/tex]
Explanation:
Generally the average velocity of the helicopter is mathematically represented as
[tex]v_{a} = \frac{\Delta D}{ t}[/tex]
substituting [tex]3.33 km = 33.3*10^3\ for\ \Delta D[/tex] and 30.0 s for t
We have
[tex]v_{a} = \frac{33.3 *10^{3}}{ 30}[/tex]
=> [tex]v_{a} = 111 \ m/s [/tex]
Now converting to km/h
[tex]v_{a} = 111 * \frac{3600 *\frac{s}{h} }{1*10^{-3} *\frac{km}{m}} [/tex]
=> [tex]v_{a} = 400\ km/h [/tex]

Answer:
Voltage is a measure of how much energy is delivered to charge. At its most basic, an electron (basic charge) is imparted 1.602×10^−19 joules when moved through an electric potential difference of one volt. An electron is then said to have an energy of 1 electronvolt. So, voltage is energy divided by charge.

First find the diameter of each.
Jupiter’s diameter is 86,881 mi.
Earth’s diameter is 7,917.5 mi.
Then divide those two.
Rounded, Jupiter is 11 times larger.
unrounded: 10.9732870224186927691821913482791285127
Finding out how large something is compared to something can be done by dividing.
For example I have two dogs. One dog is 3 feet tall. The other is 2 feet tall. How much taller is dog one? Dog one is 1.5 times larger because 3/2 = 1.5 AND 2 x 1.5 = 3.
So for this case multiplying Earth’s diameter by 10.9732870224186927691821913482791285127 will give you Jupiter’s diameter.
