Sanzida conducted an experiment that required a wire carrying a current to be wrapped around a metal core. When she placed the South Pole of a bar magnet near the top of the metal rod, she observed the magnet move toward the rod. Which conclusion can Sanzida draw from this experiment?

A) the current in the wire has created a gravitational field with its South Pole at the top of the rod

B) the current in the wire has created a magnetic field with its South Pole at the top of the rod.

C) the current in the wire has created a magnetic field with its North Pole at the top of the rod.

D) The current in the wire has created a gravitational field with its North Pole at the top of the rod

Answer:

They both act between two bodies without any means of contact. However gravitational force acts on mass while the electric force acts on charge. Gravitational force are only attractive while electric field can be attractive/repulsive. Electric field is much stronger than gravitational field.

Explanation:

The tree will fall in the south eastern side of the area due to two bulldozer.

The tree falls in the sloppy direction due to both bulldozer which apply force from two directions. One bulldozer apply force on the tree from western side whereas the other bulldozer apply force on the tree from north side so that's why we can say that the tree will fall in the south eastern side of the area.

Answer:

Maybe it; the 4th image

Explanation:

The upper bulldozer have more force than the lower bulldozer. Therefore making the down force longer than the right force

The problem is that at the end, you owe $480, so what you have is -$480 (instead of the $480 that is written on the riddle). And when your friend gives back the $30, you will owe $450, meaning that you have

-$450.

Let's follow what you say with the proper equations.

Both your parents gave you $250, so now you have:

$250 + $250 = $500

Then you bought a phone for $450, so now you have:

$500 - $450 = $50

Then you gave $30 to your friend, so now you have:

$50 - $30 = $20

Then you gave $10 to each one of your parents, so now you have:

$20 - $10 - $10 = $0.

Now, each one of your parents wants the $240 ($250 - $10) back.

So you OWE $480 (you do not have $480, you owe it, here is the problem with the riddle reasoning).

It will be represented with a negative number:

-$480

When your friend gives you the $30 back, you add it to the above value (meaning that you give it to your parents):

-$480 + $30 = -$450

Now you owe $450 to your parents, which is the cost of the cellphone that you bought.

Answer:

Explanation:

Pressure = Force / Area

Force is weight of the upper body = mass*gravity

= 40*10 (take g as 10m/s^2)

= 400N

Area of each bone = 10cm^2 and there are two thigh bones

Total area = 10*2

= 20cm^2

= 0.002m^2

Pressure = 400/0.002

= 200000 N/m^2

= 2*10^5 Pa

Answer:

Cosmologists estimate that the acceleration began roughly 5 billion years ago. Before that, it is thought that the expansion was decelerating, due to the attractive influence of matter. The density of dark matter in an expanding universe decreases more quickly than dark energy, and eventually the dark energy dominates.

Hot air balloon

Explanation:

Hot air balloon - A heater inside the balloon heats the air and so the air moves upward. This causes the balloon to rise because the hot air gets trapped inside. When the pilot want to descend, he releases some of the hot air and cool air takes it place, causing the balloon to lower.

The sound waves are defined as the frequency of sound waves and the speed of the sound wave.

The sound wave is defined as the back and forth motion of the particles in an elastic medium of mechanical waves.

The number of wavelengths passing through a point per unit of time is known as the frequency of the sound wave. Frequency is the number of waves produced by a source per second, it is measured in hertz (Hz).

The period of the sound waves is defined as when a sound wave completes one complete oscillation it is termed as the period and we measure it per second.

The speed of the sound waves is defined as the distance traveled by the sound wave in one second it is measured in meters per second. The speed of the sound wave describes the frequency as well the wavelength also.

Thus the sound waves are defined as the frequency of sound waves and the speed of the sound wave.

As per the provided information in the given question, we have been given that the Mass of the object is 13.03 Kg . Acceleration is given 13.74 m/s . And, we have been aksed to calculate the Force on the object .

For calculating the Force , we will use the Formula :-

Therefore , by Substituting the given values in the above Formula :-

⇒ Force = Mass × Acceleration

⇒ Force = 13.03 × 13.74

⇒ Force = 179.03

V=fx

where V is velocity of sound wave ; 330m/s

f is frequency of sound wave ; unknown

x is wavelength of sound wave; 0.450m

substituting the values

V=fx

330=0.450f

f=733.3

The current in the wire has created a magnetic field with its north pole at the top of the rod.  A magnetic field influences electric currents.

A magnetic field is a type of field that influences the position and direction of the electric current.

The magnetic field also refers to the one where magnetic forces act to shape an electrical current.

The only material and/or body capable of altering an electrical current in a magnetic field is the presence of another magnetic field.
