The magnetic field of a bar magnet Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. a Always points from north to south, whether we look outside the magnet or inside the magnet. b Always points from south to north, whether we look outside the magnet or inside the magnet. c Points from north to south outside the magnet, but south to north inside the magnet. d Points from south to north outside the magnet, but north to south inside the magnet.
Answer:
A: Always points from north to south, whether we look outside the magnet or inside the magnet
Explanation:
When we freely suspend a bar magnet, it's magnetic field will always rest in the north to south direction due to the fact that the Earth's magnetic south pole usually lies in the direction of the geographic north while the Earth's magnetic north pole usually lies in the direction of the geographic south.
Now, we all know that in magnets, like poles will repel and unlike poles will attract. What this now means is that the magnet will always point from the north to the south direction.

What are the lower and upper fixed points of a laboratory thermometer in Celsius degrees?
The lower fixed point, or ice point, is the temperature of pure melting ice at normal atmospheric pressure. The upper fixed point, or steam point, is the temperature of pure boiling water at normal atmospheric pressure.
heena wants to measure the volume of a ball that is 24 cm across. How should she set up her equation? v = one-third pi 24 squared (12). v = one-third p 12 squared (24). v = four-thirds pi 24 cubed. v = four-thirds pi 12 cubed.
Answer:
v = four-thirds pi 12 cubed.
Explanation:
A ball has a spherical shape. The volume of a spherical shape can be calculated using the following formula:
[tex]V = \frac{4}{3} \pi r^3[/tex]
where,
V = Volume of Ball = ?
d = diameter of the ball = length across the ball = 24 cm
r = radius of ball = d/2 = 24 cm/2 = 12 cm
Therefore,
[tex]V = \frac{4}{3}\pi (12)^3[/tex]
Hence, the correct answer is:
v = four-thirds pi 12 cubed.

What will be the mass of a body at the center of the earth as compared to other places on
the earth?
Answer:
The mass of the object does not change by moving it to another place. ... At the center of the earth the net gravitational force is zero, so the weight will be zero, but its masses will remain same. Hence the mass at the centre of earth will be equl to 50 kg.
Explanation:
It's because the mass of the object doesn't change by moving it to next place.

Use the kinetic energy equation to explain why speed has a greater impact on kinetic energy than mass.
Answer:
KE = 1/2 M V^2 Equation to express kinetic energy
Since the result depends linearly on M and to the second power on V,
V has greater effect on the result.

A ray of light strikes a plane mirror at an angle of incidence equal to 35°. The angle between
the incident ray and the reflected ray is
A)
70°
B)
0°
C)
55°
D)
35°
Answer:
55 degrees
Explanation:
A ray of light strikes a plane mirror at an angle of incidence. The angle between the incident ray and the reflected ray is 70°. The correct option is A.
What is law of reflection?The law states that angle of incidence of the incident ray is equal to the angle of reflection through a plane surface.
Here, angle of incidence of light on a plane mirror is 35°, then the angle of reflection will also be 35°.
i = r = 35°
Then the angle between the incident ray and the reflected ray will be
i +r = 35 + 35 =70°
Thus, the correct option is A.

4. Un móvil viaja en línea recta con una velocidad media de 1200 cm/s durante 9 s, y luego con velocidad media de 480 cm/s durante 7 s, siendo ambas velocidades del mismo sentido: a) ¿cuál es el desplazamiento total en el viaje de 16 s? B) ¿cuál es la velocidad media del viaje completo?
Answer:
A) El desplazamiento total del viaje es 14160 centímetros.
B) La velocidad media del viaje completo es 885 centímetros por segundo.
Explanation:
A) El desplazamiento es el producto de la velocidad media por el tiempo. El desplazamiento total es la suma de desplazamientos asociados a cada velocidad media, entonces:
[tex]x = \left(1200\,\frac{cm}{s}\right)\cdot (9\,s)+ \left(480\,\frac{cm}{s} \right)\cdot (7\,s)[/tex]
[tex]x = 14160\,cm[/tex]
El desplazamiento total del viaje es 14160 centímetros.
B) La velocidad media del viaje es el desplazamiento total dividido por el tiempo total, es decir:
[tex]\bar v = \frac{14160\,cm }{16\,s}[/tex]
[tex]\bar v = 885\,\frac{cm}{s}[/tex]
La velocidad media del viaje completo es 885 centímetros por segundo.

A magnet can generate an electric current in a wire if the magnet is close enough to the wire and if the magnet is also
A.)strong
B.)weak.
C.)at rest.
D.)in motion.
Answer:a stro
Explanation:
A magnet can generate an electric current in a wire if the magnet is close enough to the wire and if the magnet is also in motion. The correct answer is D) in motion.
What is electromagnetic induction?When a magnetic field is in motion with respect to a conductor, such as a wire, it induces an electric current in the wire. This is because the changing magnetic field creates a changing electric field around the wire, which causes electrons to flow. The induced electric current is proportional to the rate of change of the magnetic field. This consequence is known as electromagnetic induction.
The strength of the magnetic field does affect the magnitude of the induced electric current, but the magnetic field must be in motion in order to generate an electric current.
A weak magnetic field can still generate an electric current in a wire if it is in motion with respect to the wire.
If a magnetic field is at rest, it will not induce an electric current in a wire. The magnetic field must be in motion in order to generate an electric current.
Thus, the correct answer is D) in motion.

An effect analogous to two-slit interference can occur with sound waves, instead of light. In an open field, two speakers placed 1.19 m apart are powered by the same function generator producing sine waves at 1,163 Hz frequency. Assume that the speed of sound is 340 m/s. A student walks along a line 12.5 m away and parallel to the line from one speaker to the other speakers. She hears an alternating pattern of loud and quiet, due to constructive and destructive interference. What is the distance between the central maximum and the first maximum (loud) position along this line in m
Answer:
3.04 m
Explanation:
The interference by diffraction of waves is noticeable only when the dimension of the opening through which the wave is passing through is comparable to the wavelength of the passing wave.
It is given that :
Distance between two speakers, d = 1.19 m
Speed of sound, v = 340 m/s
The frequency is f = 1163 Hz
Distance the student walk along the line of the speaker, D = 12.5 m
We know the wavelength of the sound produced by the speakers is given by :
[tex]$\lambda=\frac{v}{f}$[/tex]
[tex]$=\frac{340}{1163}$[/tex]
= 0.29 m
Now the distance between the central maximum and the first maximum position is given by :
[tex]$y=\frac{\lambda D}{d}$[/tex]
[tex]$=\frac{0.29 \times 12.5}{1.19}$[/tex]
= 3.04 m
