Define the following terms: a) Heating effect of electric current b) Magnetic effect of electric current. c) Electric fuse. d) Transpiration e) Electromagnet
Answer:
A.) When an electric current is passed through a conductor, it generates heat due to the hindrance caused by the conductor to the flowing current. The work done in overcoming the hindrance to the current generates heat in that conductor.
B.) The magnetic effect of electric current is known as electromagnetic effect. It is observed that when a compass is brought near a current carrying conductor the needle of compass gets deflected because of flow of electricity. This shows that electric current produces a magnetic effect
C.) An electric fuse is an electric device which interrupts the flow of current in an electric circuit. It is installed in a circuit to stop the flow of excessive current. A fuse is usually a short piece of wire. Normally an alloy of tin and lead is used as the fuse wire, as it has high resistivity and low melting point.
D.) the act or process or an instance of transpiring especially : the passage of watery vapor from a living body (as of a plant) through a membrane or pores.
E.) An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets usually consist of wire wound into a coil. A current through the wire creates a magnetic field which is concentrated in the hole, denoting the centre of the coil.

Answer: the 3rd one
Explanation:
There was a head-on collision between a compact hybrid car and a SUV.
According to Newton’s 3rd law, the force exerted on each other is the same.
So, why are people in the smaller car more likely to get injured than those in the large one, assuming both cars are equally strong?
Vocabulary: inertia, mass, acceleration, force, unbalanced, balanced, Newton's 2nd Law
Answer:
hey im back
Explanation:
The reason behind why people in the smaller car are more likely to get injured than those in the large one is greater acceleration of the small car.
What is acceleration?Acceleration is rate of change of velocity with time. Due to having both direction and magnitude, it is a vector quantity. Si unit of acceleration is meter/second² (m/s²).
When There was a head-on collision between a compact hybrid car and a SUV, according to Newton’s 3rd law, the force exerted on each other is the same. But .
As from Newton's 2nd Law, we know that numerical value of force is simply multiplication of mass and acceleration. So, due to having small mass, smaller car suffers more acceleration for same amount of unbalanced force.
This acceleration acts against current inertia of motion of both cars and try to change it. As small car has greater acceleration, people in the smaller car are more likely to get injured than those in the large one although both cars are equally strong.

Why does the total amount of energy remain constant in the law of conservation of energy?
Thanks
Answer:
Mechanical energy is the sum of the potential and kinetic energies in a system. The principle of the conservation of mechanical energy states that the total mechanical energy in a system remains constant as long as the only forces acting are conservative forces.
Explanation:
Answer:
The energy conservation law is a consequence of the shift symmetry of time; energy conservation is implied by the empirical fact that the laws of physics do not change with time itself.

Which of the following statements about colloids is FALSE?
(1 Point)
a. A colloid contains particles smaller than those in a suspension but larger than those in a solution.
b. A colloid does not settle out, because the particles are constantly tossed about by the movement of the liquid
particles.
c. A colloid is not a true solution.
d. A mixture of sand and water is an example of a colloid.
Answer:
b
Explanation:
A non-polar molecule is:
a. easily dissolved in water AND uncharged.
b. easily dissolved in water AND charged.
unlikely to dissolve in water AND charged.
d. unlikely to dissolve in water AND uncharged.
C.
Answer:
A
Explanation:
A nonpolar molecule has no separation of charge, so no positive or negative poles are formed. In other words, the electrical charges of nonpolar molecules are evenly distributed across the molecule. Nonpolar molecules tend to dissolve well in nonpolar solvents, which are frequently organic solvents.

You read that light waves travel through air and water at different speeds. What is one way this can affect what you see around you?
Answer:
light waves slow down in water.
Explanation:
light can reflect off of different surfaces, and in water they slow down.
for example, in a completely black room, the light cannot bounce/reflect off of the walls, that's why it is so dark.
hope this helps!
The Light travels faster in air than it travels in water.
The speed of light decreases when it enters from a rarer medium to denser medium and increases when it enters from a denser medium to rarer medium. Therefore, the speed of light increases when light ray passes from water to air and the speed of light decreases when light ray passes from water to glass.When the light wave moves from air to water, it slows down. This change in speed causes the light wave to bend.Learn more:

A 20 pound barbell is brought from earth to the International Space Station(ISS). How does this trip affect the
gravitational force between the two ends of the barbell? Assume the distance between the barbell end masses does not
change.
-I
11-
A The gravitational force between the ends increases.
B The gravitational force between the ends decreases.
The gravitational force between the ends remains the same.
D The gravitational force between them decreases by one half.
The gravitational force between them doubles.
Answer:
B The gravitational force between the ends decreases
Explanation:
Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces.

What are some similarities and differences between the Geocentric model and the Heliocentric model?
Explanation:
Both were created by a Greek astronomer. Both are ways to display the Universe. The models both contain 3 main objects: Earth, Sun, and other planets. Planets orbit in some way.The geocentric model says that the earth is at the center of the cosmos or universe, and the planets, the sun and the moon, and the stars circles around it. The early heliocentric models consider the sun as the center, and the planets revolve around the sun.

Please answer ASAP, the one who is the correct will get brainliest
Explanation:
heating .....- The reason behind the heating effect of electric current is when the current passes through a conductor the electrons have to face the resistance of the conductor which results in the loss of energy and this loss of energy gets converted into heat energy.
magnetic.......- Magnetic effect of electric current - " The production of magnetic field around a conducting wire when electric current is allowed to flow through it, is called magnetic field of electric current."
electric...... - The fuse is a device used in an electrical circuit for protecting electrical devices against overloads and short circuit. It is the simplest and cheapest devices used for interrupting an electrical circuit under short circuit or excessive overload current magnitudes.

What conclusion would you draw if a seismogram from a particular seismic station showed only P waves?
Answer:
The Earthquake occurred on the other side of the Earth
Explanation:
One of the main difference between P-waves and S-waves is that P-waves can travel through solids and liquids, while S-waves can only travel through solids. They are not able to travel through liquids.
So, if a seismic station showed only P waves, it means that there was some area in liquid state between the seismic station and the hypocenter of the earthquake. Inside the Earth, the outer part of the core is made of liquid, so this means that there outer core was along the line connecting the seismic station and the hypocenter and "blocked" the S-waves: therefore, the earthquake occurs on the other side of the Earth.

Which of the four fundamental forces is responsible for holding together the molecules of the pizza dough as it is spinning in the air?
Answer:
None.
Explanation:
Molecules are formed by an element's need or excess of electrons. For example, in nature oxygen generally exists as 02. Other molecules are formed via chemical reaction. The example here is the burning of gasoline. Gasoline's two main byproducts are water and carbon dioxide.
Hydrogen as an atom has one electron making it unstable. Put a second hydrogen atom next to the first and the two atoms will share electrons to fill the first energy level the atom needs to be stable.
