A shopping mall has a length of 200 m and a width of 75 m. What is the area of the mall?

Answer: Interact With Charged Particles

Explanation:  

Answer:

Elastic Force

Explanation:

As we pull the spring from one of its end by some distance such that its length is stretched by some amount "x"

So here the restoring force on the spring is given as

[tex]F = kx[/tex]

so here we know

k = coefficient of elasticity

x = change in the length of spring

So here the restoring force on the spring will be Elastic force which always act opposite to the direction of displacement of the spring

Bleach is a base. Detergent is a base. Eye drops are a neutral. Lemon juice is an acid. Tea is an acid.

Acid is any material that when dissolved in water has a sour taste, alters the colour of some indicators (blue litmus paper turns red, for example), combines with some metals (like iron) to release hydrogen, reacts with bases to produce salts, and catalyses various chemical reactions. Acids are examples of both organic chemicals that belong to the carboxylic acid, sulfonic acid, and phenol groups as well as the inorganic substances known as the mineral acids, such as sulfuric, nitric, hydrochloric, and phosphoric acids. These materials contain one or more hydrogen atoms, which are discharged as positively charged hydrogen ions when they dissolve in a solution (see the Arrhenius hypothesis).

The Brnsted-Lowry theory and the Lewis theory provide broader definitions of an acid that encompass chemicals that display typical acidic behaviour as pure compounds or when dissolved in solvents other than water.

Answer: " The correct answer is "They stay in place and vibrate." For the other answer options, iron nails are solid particles and in a solid, molecules are packed together (i.e. the space between them is very small) and do not move all over the place because of a strong force of attraction between them, and it keeps its shape and stays in place and vibrate.

Explanation:

The correct option is Option A (Electric Field). Among the given options, the electric field is a vector quantity. The other quantities such as electric charge, electric energy, and electric potential difference are all scalars.

Among the given quantities, the electric field is a vector quantity, while the others are scalars. A vector quantity has both magnitude and direction, making it possible to be represented by arrows indicating the direction and strength of the field.

Key differences :

For example, the electric potential of a point charge is given by V = kQ/r, which is a scalar, whereas the electric field is defined as the force per unit charge and is a vector.

The answer is false.

A stretched rubber band has elastic potential energy.

Sample Response: The amount of solar energy that reaches the Earth’s surface depends on the weather, location, and time of year.

Answer:

We associate roughness with a greater coefficient of friction, then we think that rough surfaces on clothing would inhibit the speed of an Olympic athlete.  This is not always true because the amount of roughness might improve the way air pass through the fabric.  

One example of controlled roughness that actually promote speed are the dimples on golf balls. Dimples create turbulence around the ball, which sucks air to the ball, making its displacement easier and promoting its speed.

A substance is a single component that cannot be separated into other substances. Homogeneous mixtures exemplify this concept.

Substance refers to a single component that can't be separated into other substances through chemical means. A homogeneous mixture is a type of substance that is uniform throughout, like salt dissolved in water.

Geothermal facilities are very expensive to build and are only able to be built in areas with the correct geology. These power plants operate virtually emission and pollution free, and they do not require fuel or waste to be shipped to or from the facility.

The second option would be nuclear power plants.  However, nuclear power plants can leave behind radiation and radiated waste which is considered pollution.

Biomass power plants, geothermal power plants, and nuclear power plants are types of power plants that generate virtually no pollution.

Biomass power plants, geothermal power plants, and nuclear power plants are types of power plants that generate virtually no pollution. Biomass power plants burn organic matter (biomass) from plants to create electricity, while geothermal power plants use the natural heat flow from the Earth's core to generate steam that turns turbines and produces electricity. Nuclear power plants use fission to generate electricity without emitting air pollutants or CO2. However, it is important to note that nuclear power plants produce radioactive waste that needs to be safely stored for an extended period of time.

Answer:

4 beats per second

Explanation:

When two waves of slightly different frequencies overlap, they produce an interference pattern called beat, which consists in a periodic oscillation whose frequency is called beat frequency.

The beat frequency is equal to the absolute value of the difference between the frequencies of the two original waves:

[tex]f_{beat}=|f_1 -f_2|[/tex]

In this problem, the frequencies of the two waves are:

[tex]f_1 = 24 Hz\\f_2 = 20 Hz[/tex]

So, the beat frequency is

[tex]f_{beat}=|20 Hz-24 Hz|=4 Hz[/tex]

which corresponds to 4 beats per second.

= 0.0020108 m³

  V₁=0.002 m³, T₂ =20 °C

   V₂= ?   T₂ = 50° C

That is, 50°C - 20°C = 30 °C

       V₂ =V₁ [1 + γ(50-30)]

              =  0.002 [1 + 0.00018(30)]

              = 0.0020108 m³

Therefore; the volume of mercury at 50°C is  0.0020108 m³

Answer:

The car take the time is 3.0 sec

Explanation:

Given that,

Speed = 24 m/s

Acceleration = -8.0 m/s²

We need to calculate the time

Using equation of motion

[tex]v = u+at[/tex]

Where, v = final velocity

u = initial velocity

a = acceleration

t = time

Put the value into the formula

[tex]0=24-8.0\times t[/tex]

[tex]t =\dfrac{24}{8.0}[/tex]

[tex]t = 3.0\ sec[/tex]

Hence, The car take the time is 3.0 sec.

Answer:

The ball would have greatest speed at the bottom of ramp C

Explanation:

From the given ramps, C would generate the highest potential energy especially at the highest point that the ball starts to move down the ramp. Potential energy is the energy possessed by an object moving with a uniform velocit or at rest. Since potential energy increases with height, the potential energy gained by the ball on ramp C would cause an increase in its momentum as it glides down to the bottom of the ramp.

Electromagnetic waves are created by a charged particle that generates an electric field. The electric field creates a magnetic field. As the charged particle moves, the electric field and magnetic field keep changing, which causes the wave to move.
