The magnetic domains of an unmagnetised object are found___________A.) Parallel to each otherB.) Perpendicular to each otherC.) Pointing towards southD.) Pointing in different direction

Answers

All of the magnetic domains in an unmagnetized item, such as the original piece of metal in our experiment below, point in different directions.

When a metal gets magnetized, as when it is rubbed with a strong magnet, all like magnetic poles line up and point in the same direction. Atoms in ferromagnetic materials form formations known as domains. A domain is an internal region of a material in which groups of magnetic moments spontaneously align in the same direction. When the external field is withdrawn, the domain walls are pinned in their new orientation, and the aligned domains generate a magnetic field. This is what happens when a ferromagnetic material is "magnetized" and transformed into a permanent magnet.

An ant starts at one edge of a long strip of
paper that is 30.8 cm wide. She travels at
0.6 cm/s at an angle of 40◦ with the long edge.
How long will it take her to get across?
Answer in units of s.

Answers

it take the ant   68.9 seconds to get across  the other edge of a long strip.

How do we calculate for velocity?

If the ant is moving at a constant speed, the velocity vector will have the same magnitude at any point, and can be decomposed in two vectors, along directions perpendicular each other.

So then, if we choose these directions coincident with the long edge of the paper, and the other perpendicular to it, the components of the velocity vector, along these axes, can be calculated as the projections of this vector along these axes.

We only are interested in the component of the velocity across the paper, that can be calculated as follows:

vₓ = v* sin θ, where v is the magnitude of the velocity, and θ the angle that forms v with the long edge.

We know that v= 0.6 cm/s, and θ = 40º, so we can find vₓ as follows:

vₓ = 0.6 cm/s x sin 40 º

Vx = 0.6 cm/s x 0.7451 =  0.447 cm/s

Applying the definition of average velocity, we can solve for t:

time =  30.8 cm/ 0.447

a 1 kg blob of putty moving at 10 m/s runs into another 1 kg stationary blob, and they stick together. the momentum of the blobs after the collision is

Answers

The momentum of the blobs after the collision of a 1 kg blob of putty moving at 10 m/s with another 1 kg stationary blob will be 5 m/s.

The term "completely inelastic collision" is used to describe every time two masses cling together after colliding. Any inelastic collision will result in the internal energy of the objects being transformed into kinetic energy. Because of this, even though the system's energy is conserved (no outside forces are at action), its internal energy is changing in an unknowable and unpredictable fashion. This implies that the concept of energy conservation in inelastic collisions is absolutely meaningless to us. However, the conserved quantity that we can monitor is momentum.

Initial momentum is expressed as p = m1v1 + m2v2,

where, I denotes vector quantities.

v2 = 0  (because the second blob is at rest).

As a result, p=m1v1, |p|=m1|v1|=1*10= 10 kg*m/s,

The total amount of momentum is conserved in a closed system. The end momentum is 10 kg*m/s and is therefore also directed in the same direction as the beginning momentum.

The combined mass is now M=m1+m2= 1+1 = 2 kg due to the fact that two blobs are now clumped together. As a result, p = mv= 10 =2v; from this, v= 10/2 = 5 m/s, headed in the same direction as the first blob's starting velocity.

Answers

For the chain: linear density =ρ, length =l. The chain is placed on a smooth plane. The speed of the chain when the left end leaves the plane is the same as its initial speed, which is zero.

What is speed?

Generally, To determine the speed of the chain when the left end leaves the plane, we need to consider the forces acting on the chain and use Newton's second law to find the acceleration of the chain.

The forces acting on the chain are the force of gravity and the normal force from the plane. The force of gravity is downward and is equal to the weight of the chain, which is given by the equation:

Fg = mg

where m is the mass of the chain and g is the acceleration due to gravity. The normal force from the plane is upward and is equal to the force of gravity, since the chain is stationary at this moment.

Newton's second law states that the acceleration of an object is equal to the net force acting on it divided by its mass. Therefore, the acceleration of the chain is given by:

a = (Fg - Fn)/m = (mg - mg)/m = 0 m/s^2

Since the acceleration of the chain is zero, the speed of the chain does not change as it drops.

In this figure, why is the kinetic energy gained by the falling ball equal to the change of potential energy? (Assuming no loss of energy due to friction.)

Answers

Kinetic energy gained by the falling ball is equal to the change of potential energy is because mechanical energy remains conserved ,it only converts from one form to another form.

The mechanical energy stays rationed when just inner powers follow up on the body and no outside powers are in real life. It implies that motor and potential might continue to change all through the excursion. Be that as it may, their total is steady at each point.

The forces are moderate, i.e., they don't rely upon the way of the moving article and are just subject to the beginning and last position. For instance, the gravitational power is moderate in nature, though the opposition presented via air is non-moderate in nature as it relies upon the way.

From the diagram,we can see that object has potential energy =mgh because of height h.When it was dropped from height h potential energy starts decreasing and kinetic energy starts increasing because of velocity attained by the body.Since mechanical energy is conserved,therefore kinetic and potential energy is equal.

The total voltage in the circuit is 8 V. Then, the current passing through the resistor R3 is 1.95 A. The power supply to this resistor by the batteries is 15.6 W.

What is Ohm's' law?

According to Ohm's law, the voltage through a closed circuit is the product of the current passing through the circuit and resistance through it.

Hence, V = I R.

Given that the resistance through the resistor R3 = 4.10 Ω

The voltage across each batteries = 4 V

Total voltages =  4 + 4 = 8V

Current = voltage/ resistance

             = 8 V/ 4.10 Ω

             = 1.95 A.

Power through a circuit is the product of current and voltage through it.

P = I V

Power supplied to R3 = 1.95 A × 8 V = 15.6 W.

Therefore, the power supplied by the batteries to the resistor R3  is 15.6 W.
