Answer:

Universal Gravitational Constant

Explanation:

Universal Gravitational Constant or G is used in calculating the gravitational force between two objects. The force (F) is given by,

[tex]F = \frac{GMm}{r^{2}}[/tex]

where,

M and m = mass of two objects

r = distance between the centers of the two objects

The value of G with an accuracy of 99% was first calculated by Henry Cavendish in 1798.

The value of [tex]G = 6.67 \times 10^{-11}[/tex] m³kg⁻¹s⁻²

Answer:

G = Fr2/m2

Explanation:

we have to isolate G

multiply r2 on both sides

Fr2 = gm2

and then divide m2

Fr2/m2= G

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.

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:

Cross contamination.

Step-by-Step Explanation:

The contamination that results  from spread of bacteria from meat to vegetable is called cross contamination which means the bacteria from one type of food transferred to  other food which eventually spoil the food.

This happens by direct contact of two types of food.

The contamination that results from the spread of bacteria from meat to vegetables is called Cross-contamination.

Cross-contamination is the movement of bacteria or other pathogenic microbes from one food item or surface to another, which can result in the spread of diseases.

In the case of meat and vegetables, cross-contamination can happen if bacteria from uncooked or carelessly handled meat come into contact with vegetables, either directly or through shared surfaces. This may occur while handling, storing, or preparing food.

Using separate cutting boards and utensils for raw meat and raw vegetables, washing your hands completely after handling raw meat, and storing meat and vegetables separately in the refrigerator are all critical ways to reduce the risk of cross-contamination.

Hence, the contamination that results from the spread of bacteria from meat to vegetables is called cross- contamination.

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.

The metric system is used in science because it is universally adopted, easy to convert, and flexible across large and small numerical ranges. Every unit in the metric system increases by a factor of ten, an advantage not found in the U.S customary units. Metric units are easily scalable across different fields, making it a practical choice in science.

In the realm of science, it is more common to use the metric system, a measurement system adopted by most countries, except the United States. A core advantage of adopting this system is that every unit increases multiplicatively by a factor of ten. The base units of the metric system are the meter for length, kilogram for mass, and second for time.

One significant advantage of such system is its flexibility in scaling across extremely large or small numerical ranges simply through the use of an appropriate metric prefix, making it universal across various scientific and professional fields. For instance, in construction, one would most likely deal with meters, whilst in aviation, kilometers are more suitable, and nanometers find their use in optical design.

Unlike in the system of U.S customary units where conversions between various units might be complicated, the metric system offers simple conversions by merely shifting the decimal place of a number due to the sequential powers of 10 of the metric prefixes.

Answer:

Velocity of plane = 30.93 m/s

Explanation:

Considering vertical motion of ball

    Initial velocity, u =  0 m/s

   Acceleration , a = 9.81 m/s²

   Displacement, s = 195 m

   We have equation of motion s= ut + 0.5 at²

   Substituting

       s= ut + 0.5 at²

       195 = 0 x t + 0.5 x 9.81 x t²

        t = 6.31 seconds

Now considering horizontal motion of ball

   Acceleration , a = 0 m/s²

   Displacement, s = 195 m

   Time, t = 6.31 s

   We have equation of motion s= ut + 0.5 at²

   Substituting

       s= ut + 0.5 at²

       195 = u x 6.31 + 0.5 x 0 x 6.31²

        u = 30.93 m/s

Velocity of plane is horizontal initial speed of ball = 30.93 m/s

Velocity of plane = 30.93 m/s

Answer:

A. 22 Hz and 42 Hz

Explanation:

When two waves of slightly different frequency meet each other, they produce an interference pattern called beat. The frequency of this beat is equal to the absolute value of the difference between the individual frequencies of the two waves:

[tex]f_B=|f_1-f_2|[/tex]

In this problem, we have 20 beats per second, so the beat frequency is

[tex]f_B = \frac{20}{1 s}=20 Hz[/tex]

Therefore, we have to find the pair of waves whose frequency difference is 20 Hz. Let's analyze each choice:

A. [tex]f_B = |22 Hz - 42 Hz|=20 Hz[/tex] --> YES

B. [tex]f_B = |47 Hz - 55 Hz|=8 Hz[/tex] --> NO

C. [tex]f_B = |38 Hz - 63 Hz|=25 Hz[/tex] --> NO

D. [tex]f_B = |18 Hz - 26 Hz|=8 Hz[/tex] --> NO

So, the correct choice is A.

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.
