List each layer of the earth, starting at the crust, and identify one characteristic of each layer.

Answers

Answer 1

Answer:

Hope it helps

Explanation:

The inner core is solid, the outer core is liquid, and the mantle is solid/plastic. This is due to the relative melting points of the different layers (nickel–iron core, silicate crust and mantle) and the increase in temperature and pressure as depth increases

Sand can also refer to a textural class of soil or soil type; i.e., a soil containing more than 85 percent sand-sized particles by mass.

Explanation:

Interesting fact...

Why are there differences between the cooling rates of sand and water? Sand cools off faster than water because sand is a solid. Water heats up slower and cools off slower than sand. Sand heats up faster and cools off faster than water.

The procedure would be best to investigate the transfer of kinetic energy is Determine temperature and mass of water. Put ice in water. Record the time for ice to melt. Therefore, option 4 is correct.

What do you mean by kinetic energy ?

The term kinetic energy is define as the energy of motion, observable as the movement of an object. The formula of kinetic energy is as follows:

Kinetic energy = 1/2 mv²

Kinetic energy exists in every moving object and particle. Kinetic energy is demonstrated by a person walking, a soaring baseball, a crumb falling from a table, and a charged particle in an electric field.

Kinetic energy is the energy held by a moving object. Kinetic energy exists in the earth's rotation around the sun, you walking down the street, and molecules moving in space.

Thus, option 4 is correct.

Explanation:

The temperature of the sample in which the color spreads quickly is higher than sample 1. Hence, statement d is correct.

What is kinetic energy?

Kinetic energy of a substance is the energy generated by virtue of its motion. It is dependent on the mass and velocity of the substance. Temperature of the system also affects the kinetic energy of substance.

According to kinetic theory of matter, as thermal energy increases, kinetic energy of the particles also increases leading to more effective collisions results in reactions.

Here, the color spreads more easily in sample 2 because the higher temperature of the solution provide enough thermal energy for the liquid particles to gain kinetic energy to easily move through the solution. Thus, statement d is correct.

Which is a valid velocity reading for an object?
A.45 m/s
B. 45 m/s north
C. 0 m/s south
D. 0 m/s

Answers

The answer is B. You cannot have 0 velocity. If you don’t include direction, then it is only considered speed.

The valid option would be 45 m/s north. This option specifies a velocity of 45 meters per second in the north direction. It includes both the magnitude (45 m/s) and the direction (north) of the velocity. Hence the correct option is (A).

A. 45 m/s: This indicates a velocity of 45 meters per second without specifying the direction. It represents the magnitude of the velocity but does not indicate a particular direction.

B. 45 m/s north: This indicates a velocity of 45 meters per second in the north direction. It specifies both the magnitude (45 m/s) and the direction (north).

C. 0 m/s south: This indicates a velocity of 0 meters per second in the south direction. No velocity. It specifies both the magnitude (0 m/s) and the direction (south).

D. 0 m/s: This indicates a velocity of 0 meters per second, meaning the object is not moving. It represents zero speed and zero direction.

The correct option is (A).

1. Mass no.= protons+ neutrons,
Therefore, mass no. of sodium = 11 + 12 = 23

2. Total no. of electrons in a neutral sodium atom (has not reacted with anything, thus has not lost any electrons, thus is neutral) = Atomic no. = electron no. = 11

3. So as mass no. of magnesium is 24, and mass no. = protons+neutrons, and no. of protons is 12, then no. of neutrons= atomic no. - protons = 24-12= 12

4. Atomic no. = no. Of electrons= 13

5. Mass no. = protons+neutrons= 31
No. Of neutrons=16
Therefore, no. Of protons= Mass no. - neutrons= 31-16=15
Also- no. Of protons=no. Of electrons= 15 (another way to solve)

Answer:

Explanation:

hope this helps :)

A force of 1000 pounds drags a truck 50 feet in 10 seconds. then the work accomplished is 50000 lbs feet and the power required was 5000ft-lbs/sec.

What is Force ?

Force is responsible for the motion of an object. it produces acceleration in the body. According to newton's second law force is mass times acceleration i.e. F =ma. Its SI unit is N which is equivalent to kg.m/s². There are two types of forces, balanced force and unbalanced force. Balanced forces are those forces which are opposite in direction and equal in magnitude. When Net force acting on a body is zero then we call it as balanced force. Balanced force is not responsible for the motion of the body. ex. when two persons pulling rope on both end with equal magnitude which cause them to be balanced force have 0 net force. Unbalanced forces are those when resultant of all the forces is not equal to zero is called as unbalanced force. unbalanced force is responsible for the motion of the body.

Given,

F = 1000 pound

s = 50 feet

t = 10 s

Work = F.s = 1000 * 50 = 50000 lbs feet

Power = Work/time = 50000/10 = 5000ft-lbs/sec

Hence option A is correct.

What is true about the force acting on the cars at the end of a roller coaster ride as they slow down right before stopping?

Answers

That the gravity dosent Change

The cars will slow down as a result of unbalanced forces and negative acceleration.

What is Inertia?

Inertia is the ability of an object to continue its current motion until and unless some external force causes its speed or direction to change. Inertia is described in the Newton's first law of Motion.

The cars are slowed due to negative acceleration of the object eventually to a stop, because of these unbalanced forces due to friction which are acting on them. The riders, which have inertia, are also acted on by the unbalanced forces throughout the ride causing them to change their state of motion.
