Answer:

All magnets have north and south poles. Opposite poles are attracted to each other, while the same poles repel each other. When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction. The force generated by the aligned atoms creates a magnetic field.

Answer:

Yes your correct.

Explanation:

Answer:

acceleration = 0.013 m/s²

Explanation:

formula for acceleration is

a = (v-u) / t

a= (0.7-0.3) / 30

= 0.013

The acceleration of a turtle going from 0.3 m/s to 0.7 m/s in 30 seconds is 0.0133m/s²

Acceleration is defined as the change in velocity of a body with respect to time. Mathematically:

[tex]a=\frac{v-u}{t}[/tex]

v is the final speed = 0.7m/s

u is the initial speed = 0.3m/s

t is the time taken = 30seconds

Substitute the given values into the formula:

[tex]a=\frac{0.7-0.3}{30}\\a=\frac{0.4}{30}\\a = 0.0133m/s^2[/tex]

Hence the acceleration of a turtle going from 0.3 m/s to 0.7 m/s in 30 seconds is 0.0133m/s²

Explanation:

En este caso para poder calcular el error relativo porcentual, es necesario calcular primero el error absoluto, que se calcula de la siguiente forma:

Error absoluto = Resultado exacto - aproximación

Sin embargo, no tenemos el resultado exacto de las medidas, pero podriamos conocerlo tomando el promedio de estas medidas y este es el que tomaremos como el verdadero resultado de las medidas:

Promedio de medidas = 1.34 + 1.35 + 1.37 + 1.36 / 4

Promedio de medidas = 1.355 m

Ya que tenemos el promedio, podemos calcular el error absoluto de cada medida y luego el error relativo porcentual:

Ea1 = 1.355 - 1.34 = 0.015

Ea2 = 1.355 - 1.35 = 0.005

Ea3 = 1.37 - 1.355 = 0.015

Ea4 = 1.36 - 1.355 = 0.005

Ya que tenemos los 4 errores absolutos, es posible calcular el porcentual:

%error relativo = (Error absoluto / resultado exacto) * 100

Aplicando la expresión con cada uno de los valores tenemos:

%Er1 = (0.015/1.34) * 100 = 1.12%

%Er2 = (0.005/1.35) * 100 = 0.37%

%Er3 = (0.015/1.37) * 100 = 1.09%

%Er4 = (0.005/1.36) * 100 = 0.37%

Answer:

frictional force

Explanation:

Answer:

The direction of these oscillations is the difference between longitudinal or transverse waves. In longitudinal waves, the vibrations are parallel to the direction of wave travel. In transverse waves, the vibrations are at right angles to the direction of wave travel.

Explanation:

The waves that contains the oscillations parallel to their direction of motion should be considered as the sound waves from stereo speaker.

A sound wave is the wave that shows the disturbance patterns that should be lead by the movement of the energy that should be travelled via the medium like air, water, since it should be propagated away from the sound source.

Therefore, The waves that contains the oscillations parallel to their direction of motion should be considered as the sound waves from stereo speaker.

Answer:

the force between the two charges is 198.37 N

Explanation:

Given;

charge of the first particle, Q₁ = -3 x 10⁻⁵ C

charge of the second particle, Q₂ = 9.0 x 10⁻⁵ C

distance between the two charges, r = 0.35 m

The force between the two charges is calculated from Coulomb's law;

[tex]F = \frac{kQ_1Q_2}{r^2}[/tex]

where k is Coulomb's constant = 9 x 10⁹ Nm²/C²

[tex]F = \frac{(9\times 10^9)(3.0\times 10^{-5})(9\times10^{-5} )}{0.35^2} \\\\F = 198.37 \ N[/tex]

Therefore, the force between the two charges is 198.37 N

More carbon dioxide or greenhouse gases in the atmosphere can lead to global warming. Oceans store a large amount of heat, and increases in sea surface temperature can increases the amount of water vapor over the oceans, and that will increases the amount of greenhouse gases.

Answer: c

Explanation:

If the net force on the bowling ball is tripled, its new acceleration is 21 m/s². The correct option is d.

The force is the action of push or pull which can move or stop the object.

The initial force is F = mass x acceleration

F = 3.17515 kg x 7 m/s²

F = 22.23 N

When the net force is tripled, the new acceleration will b e

3 x F =m x a'

3 x 22.23 = 3.17515 x a'

a' = 21.003 m/s²

Thus, the new acceleration is 21 m/s². The correct option is d.

Answer:

c

Explanation:

because newton's second law states that F= MA

which suggests that if M increases, F also increases which is the force,

let me give you a tip, during exam, just type any random numbers into the formula, like at first you type 5 into the M, then increase M, by putting 10 into the M , keep the acceleration the same for this, okay?

you will see that the force will increase,

by this I mean that option says largest mass, so the force will also be very big because in reality do you use more force on heavier box or a lighter one to push it across the room?

so larger mass, larger force, greater acceleration

but the question is not being clear, whether to the force remains constant for every object, if it does then A is false . and B is false because if the forces is constant, and it is light, it would require a small amount of force ,

but the other options, gave us a clue about the force so you can choose either c or d but see the explanation above,

the only corrext option will be c.

if not, please report this, someone will have a go at it

Answer:

375J

Explanation:

W=F x d

=250 x 15

=375J

The work W is equal to the force f times the distance d, or W = fd, to mathematically describe this idea. If the force is applied at an angle to the displacement, the work is W = fd cos.

Work in physics is the energy that is transferred to or from an item when a force is applied along a displacement. In its simplest form, For a constant force that is oriented in the same direction as the motion, it is easiest expressed as the product of the force's magnitude and the distance travelled.

A desk is being subjected to applied force if someone is pushing it across the room. The person's force applied to the desk is known as the applied force.

Mass and weight are not the same.The normal force is the supporting force exerted on an object when it collides with another stable object.

Therefore, W=F × d =250 × 15 =375J
