B.

C.

D.

Answer:

See explanation below

Explanation:

Let's recall what's the law of acceleration.

First of all, the acceleration is a vector that has the change of velocity in function of the time.

Now, the law of acceleration is related to Newton's Second law which states that an object will move only if there are forces around it. In other words, the following expression:

F = m . a

Now, in this case, we know that the acceleration of an object is affected by a force always. So, if an object stand still, it will not move unless you push it or pull it to move, and the acceleration will speed up or down depending of the force it was exerted.

According to this, the law of acceleration can be applied here:

1. A bike going down a hill. Of course, because, let's suppose you let a bike alone go down on a hill, you will see that the speed of the bike will be faster as time goes by. This is because the force acting here is the weight of the bike and gravity.

2. Dropping a ball from a building. In this case, you drop a ball from a high floor on a building, it will happen the same thing as the bike. It will go faster because of gravity.

3. Putting the break on a car. Now in this case it's easy because you only need to know that when you put the brakes, the speed of the car will go down, but also the acceleration. So there's no need of a further explanation of this.

Answer:

D

Explanation:

Purview is the word that best replaces reach without changing the meaning of the sentence. Therefore, the correct option is option B.

A sentence is indeed a collection of words used to express a thought. A sentence always begins with such a capital letter then concludes with a period, punctuation mark, and exclamation point. Ideal sentence construction has a verb and a subject. Declarative sentences make a declaration, express an opinion, or make an emotion known.

Declarative sentences have a period at the end. Questions are asked in sentences known as interrogatives. These phrases are followed by a question mark. This kind of phrase is used to give instructions or make a request. There is typically a period at the end, but occasionally there is also an exclamation point. Univocal means having only one possible meaning. Purview is the word that best replaces reach without changing the meaning of the sentence.

Therefore, the correct option is option B.

Answer:

Increase the pressure of the gas

Explanation:

According to the Pressure law, for a fixed mass of gas, at a constant volume (V), the pressure (P) is directly proportional to the absolute temperature (T).

From the kinetic molecular theory, gases are composed of particles which are in constant motion, colliding with themselves as well as with the walls of their container.

When the temperature of these gas molecules is increased, the molecules acquire more kinetic energy and the rate of collisions increases. Since the container cannot expand, the increase in pressure is due to the increase in collisions between the molecules of the gas as well as with the walls of their container.

Kinetic energy is the energy possessed by an object due to its motion. If an object is moving, then it has kinetic energy. If an object has kinetic energy, then it is moving. Many students confuse kinetic energy with potential energy.

Answer:

92gm

Explanation:

Atomic mass of Mg=24g=1 mole of Mg

∴  24g =1 mole of Mg contain 6.022×10^23 atom 

∴  6gm contains 246.022×1023×6

                            =4×6.022×10^23 atoms

Now according to question, there are 6.022×1023 atoms of Na 

23gm of Na contains 6.022×10^23 atoms

∴6.022×4×10^23 atoms of Na weighs 23×6.022×10^23×4/6.022×10^23⇒92gm

Answer:

osmosis. I

Explanation:

If an object/ cell is placed in a solution where the concentration is more or stronger than itself(hypertonic solution), it shrinks because water moves out of it, but if it is placed where the concentration of the surrounding solution is lesser than its concentration(hypotonic solution), it swells and can burst because water moves into it. So the mass of the egg will decrease because it is placed in an hypertonic solution (salt water) and the concentration of the salt water is stronger than its concentration

The atomic radius of calcium is approximately 175

Explanation:

Given that the atomic radius of magnesium = 150 pm

The atomic radius of strontium = 200 pm

Therefore, given that calcium comes in between magnesium and strontium in group 2 of the periodic table, the atomic radius should be half way between the length of the atomic radius of magnesium and strontium, given that the atomic radius is not a fixed quantity

Therefore;

The atomic radius of calcium is approximately given as follows;

The approximate atomic radius (200 + 150)/2 = 175 pm.

The heating of the Earth's surface and atmosphere by the sun drives convection within the atmosphere and ocean. This convection produces winds and ocean currents. The greater the pressure differences between a low-pressure area and a high-pressure area, the stronger the winds. I hope this helps

The sun heats the air near the equator of the earth, it becomes less dense and rises upward. As warm air rises, it cools and gets less dense than the air around it.

Convection can be d defined as the transfer of heat from one place to another due to the movement of heat or fluid. Convective heat transfer involves the processes of conduction as well as advection.

Gases and liquids can not be good conductors of heat under normal conditions, but they can easily transfer heat.

Convection occurs through diffusion or advection but does not take place in solids, as there is no movement of its constituent particles happens. The diffusion of heat in solids is known as thermal conduction.

The heat transfer that occurs between a surface and a liquid that is in contact with the surface is convection heat transfer.  

The Sun provides the energy for the convection in the ocean and produces ocean currents. There are two kinds of ocean currents: one is surface currents and the other deep currents.
