Explanation:

The terms heavy and light are commonly used in two different ways. We refer to weight when we say that an adult is heavier than a child. On the other hand, something else is alluded to when we say that rock is heavier than soil. A small rock would obviously weigh less than a roomful of soil, but rock is heavier in the sense that a rock of given size weighs more than the same-size sample of soil. What we are actually comparing is the mass per unit volume, that is, the density. In order to determine these densities, we might weigh a cubic centimeter of each sample. If the rock sample weighed 2.71 g and the soil 1.20 g, we could describe the density of the rock as 2.71 g cm–3 and that of the soil as 1.20 g cm–3. Even though sand is made of rock fragments, its density is less because the porosity of sand lowers its bulk density (as shown below). (Note that the negative exponent in the units cubic centimeters indicates a reciprocal. Thus 1 cm–3 = 1/cm3 and the units for our densities could be written as g/cm3, or g cm–3. In each case the units are read as grams per cubic centimeter, the per indicating division.) We often abbreviate "cm3" as "cc", and 1 cm3 = 1 mL exactly, by definition.

Starburst galaxies is simply known as the rate at which the galaxy is now converting gas into stars. The statement that is not a general characteristic of starburst galaxies is that The "starburst" is thought to be caused by the presence of a supermassive black hole in the galaxy's center.

They are known to be rare. A starburst is known to be an astrophysical process. It is the process of star formation happening at a rate that is large when compared to the rate that is often observed.

Unbalanced or net forces acting on the car will cause it to move

The correct answer is option D. The net force on the car is zero​.

Since the car is not accelerating, the force of air resistance and the friction force must add to give the exact opposite of the applied force. The net force here would be zero, as well.

Newton's First Law is the law of inertia. An object with no net forces acting on it which is initially at rest will remain at rest. If it is moving, it will continue to move in a straight line with constant velocity.

Answer:

C

Explanation:

The attractive force of their magnetic fields is greatest at the poles. Option B is correct.

Earth's magnetic field is similar to that of a bar magnet in that both have north and south poles. The magnetic field lines of both Earth and a bar magnet originate from the north pole and loop around to the south pole. The magnetic field lines are most concentrated and the attractive force is strongest near the poles of both Earth and a bar magnet.

At the poles, the magnetic field lines are densely packed and closely spaced, leading to a stronger magnetic force. This is why compass needles, which align with Earth's magnetic field, point towards the magnetic north pole.

The statement about electric current causing them to lose magnetism (option D) is not accurate. Electric current can actually create magnetic fields, as seen in electromagnets. Earth's magnetic field is generated by the movement of molten iron in its outer core, not by electric currents in the conventional sense.

In summary, option B is the correct answer as it accurately reflects the similarity in the distribution of magnetic field lines and the strength of the attractive force near the poles for both Earth and a bar magnet.

Explanation:

Given our understanding of physics, we can conclude that once the balloon is pushed under the surface, it will sink.

One key factor to take into account here is to remember that the density of a ballon can change when exposed to a higher pressure. This is due to the elastic nature of the material that makes up the ballon, and the nature of gas atoms that allow them to be compressed.

Therefore, when the balloon is pushed underwater, the surrounding water will squeeze the balloon, thus incrementing its density. Once the density of the balloon rises, this, in addition to the weight to which it is attached, will make it heavier than the water it is in, and the balloon will sink.

Answer:

C) an investigation of conduction through collisions between particles in space

Answer:

.1 A1 = a1      A1 is amount at .1 %

.01 A2 = a2    A2 is the amount at .01%

a1 + a2 = 454     total of a1 and a2

A = 454 / .03  =  15133.33    tot amount needed

454 = .1 A1 + .01 A2    

A2 = 15133.33 - A1    

454 = .1 A1 + .01 (15133.33 - A1)

454 = .09 A1 + 151.33

A1 = 302.67 / .09 = 3363

A2 = 15133.3 - 3363 = 11770.3

Check:

.1 * A1 = 336.3

.01 * A2 = 117.7

total = 336.3 + 117.7 = 454

Answer:

c. postive

Explanation:

All physical objects are made up of atoms. Inside an atom are protons, electrons and neutrons. The protons are positively charged, the electrons are negatively charged, and the neutrons are neutral.

Therefore, all things are made up of charges. Opposite charges attract each other (negative to positive). Like charges repel each other (positive to positive or negative to negative). Most of the time positive and negative charges are balanced in an object, which makes that object neutral.

Static electricity is the result of an imbalance between negative and positive charges in an object. These charges can build up on the surface of an object until they find a way to be released or discharged. One way to discharge them is through a circuit.

Explanation:

C because if you build anything up it remains the same.

There are many reasons actually...

◇ Clayey soil is easy to mould than the other soils.

The other soils (like sandy soil & loamy soil) are grainy or dry in nature & cannot be moulded. In the ancient times, when technology & the know-hows were still not introduced, people used clayey soul to make earthern pots to store stuff. This practice still continues even today.

◇ It keeps water cool.

Ever wondered why water stored in the earthenware remains cool even on a sunny day? It's because the heat required for evaporation is taken from water inside the pot & thus it cools the water stored inside.

◇ Clayey soil is also moist, durable, more plastic like & easy to retain making it ideal for potters to make earthenware.

__________

Clay soil is used to make earthenwares because, clay can be easily molded to desired sizes and shapes. Clay absorbs water moiety and make the pot very cool inside.

Clay is a type of soil made by the sedimentation process near water resources.  They are rich in minerals. Clay is rich in silicates and intermolecular force in the soil is comparatively less and can be easily molded any shape and size.

When clay is fired to a high enough temperature, the glass-forming materials in the ceramic form a liquid glass. This glass bridges the gaps between the clay particles. As the pottery cools at the end of the firing process, the glass between the clay particles solidifies again.

Clay pots make the water cooler inside. Hence, clay is used to make earthen wares.
