Answer:

Climate.

Explanation:

Weather can be defined as the atmospheric conditions of a particular area over a short period of time.

The elements of weather include precipitation, wind, temperature, atmospheric pressure, relative humidity, cloud, and wind speed.

The long-term average weather for a region is called climate.

This ultimately implies that, when the average atmospheric conditions prevailing in a specific region persists for a very long period of time, it is known as climate.

Electromagnets are an example of how electricity can create magnetism is True statement.

Permanent magnets are not the same as electromagnets. Coils of wire with electricity running through them make up electromagnets. An electromagnet's wire coils act like magnets when an electric current flows through them because moving charges produce magnetic fields.

The coils stop functioning as a magnet when the electricity is turned off. When magnetic forces are only required for brief periods of time, electromagnets are frequently used in electrical equipment.

They both make use of electromagnets, which use electricity to apply a magnetic field. Extremely strong electromagnets are used by wrecking yards to transfer heavy scrap metal or even entire cars from one location to another.

Therefore, Electromagnets are an example of how electricity can create magnetism is True statement.

Answer:

The plane travels at a rate of 313 meters per second.

Explanation:

Since the speed of sound at an elevation of 40,000 feet, where many aircraft fly, is 295 m / s, if an airplane is flying at Mach 0.92 at this altitude, to determine how fast is the airplane traveling in meters per second you must perform the following calculation:

1 Mach = 1,225.04 km / h

1 km = 1,000 m

1 h = 3,600 sec

1 = 1225.04

0.92 = X

0.92 x 1225.04 = X

1,127.03 = X

(1,127.03 x 1,000) / 3,600 = X

1,127,030 / 3,600 = X

313.06 = X

Thus, the plane travels at a rate of 313 meters per second.

Explanation:

Group 18 are the noble group so 16 + 2 = 18

Answer:

2 * 10^5 pa

Explanation:

Pressure = Force / Area

Each thigh bone has a cross sectional area of 10cm²

Both thigh bones :

2 * 10cm² = 20cm²

To m² : 20 * (0.01)²

20 * 0.0001 m² = 0.002 m²

Force = mass * acceleration due to gravity(g)

g = 10m/s² ;

Force = 40 * 10 = 400N

Pressure = 400 N / 0.002 m²

Pressure = 200,000 N/m² = 2 * 10^5 pascal

Answer:

322.5mL

Explanation:

According to Charles's law, which state that at constant pressure the volume of fixed mass of a gas is proportional directly to it's temperature.

This can be expressed as

V1/ T1 = V2 / T2

Where

V1= initial volume= 693 mL

V2= final volume

T2= final temperature=( –125°C + 273)= 148K

T1= initial temperature= (45°C+ 273)=318K

V1/ T1 = V2 / T2

693/318 = V2/148

693×148 = 318 × V2

V2=102564/318

= 322.5mL

* in a tube with both ends open

        λ = 2L / n                    n = 1, 2, 3,…

* tube with one end open and the other closed.  

         λ = 4L / n                     n = (2n ’+ 1 )

Explanation:

When a sound wave enters a pipe, a resonance process occurs, whereby only some wavelengths can occur.

* in a tube with both ends open

in this case there are maximums at each end, so if the length of the had is L

              λ = 2L 1st harmonic

              λ = 2 L / 2 2nd harmonic

              λ = 2L / 3

              λ = 2L / n                    n = 1, 2, 3,…

* In the case of a tube with one end open and the other closed.

At the open end there is a belly and at the closed end a node

              λ = 4L 1st harmonic

              λ = 4L / 3 3rd harmonic

              λ = 4L / 5

              λ = 4L / n                  n = 1, 3, 5,… odd

Answer:

mechanical energy

Explanation:

In science, matter can be defined as anything that has mass and occupies space. Any physical object that is found on earth is typically composed of matter. Matter are known to be made up of atoms and as a result has the property of existing in states.

Generally, matter exists in three (3) distinct or classical phases and these are;

1. Solid: it is the state of matter in which the physical substance has a definite shape and fixed volume but not compressible. Examples of solids are pen, screwdriver, television, car etc.

2. Liquid: it is the state of matter in which the physical substance can be poured and it takes the shape of its container. Also, liquids generally have a definite volume. Examples of liquids are urine, water, milk, blood etc.

3. Gas: it is the state of matter in which the physical substance has no definite shape or volume and as a result fills all available space. Also, gases are easily compressible and can flow. Examples of gases are hydrogen, oxygen, argon, nitrogen etc.

Generally, the form of energy associated with the particles of objects include thermal energy, nuclear energy and chemical energy.

However, a form of energy not associated with the particles of objects such as an atom is mechanical energy.

Explanation: thats whats right

The speed of the blocks after the collision is most nearly will be Vf= 2.376 m/s.

Collision is defined as when two bodies of different masses move towards each other with a particular speed, then there will be three cases after the collision.

Elastic collision, in which the kinetic energy of the object remains constant.

Inelastic collision in which the kinetic energy is not conserved after the collision.

Completely elastic collision, in which the masses stick together after the collision and  move with a final speed.

It is given in the question that

Mass of body A= 2 kg

Velocity of body A= ?

Mass of body B=3 kg

Velocity of body B= 0 m/s

since the body is coming from the inclined place at an angle 30 so the height will be calculated as:

[tex]\rm Sin\theta=\dfrac{h}{H}[/tex]

Inclined plane H=3.6 m

[tex]\rm Sin30=\dfrac{h}{3.6}[/tex]

[tex]h=1.8 m[/tex]

Now the initial velocity of the object from the conservation of energy

[tex]m_Agh=\dfrac{1}{2}m_Av_A^2[/tex]

[tex]v_A=\sqrt{2gh[/tex]

[tex]v_A=\sqrt{2\times9.81\times 1.8}=5.94\ \frac{m}{s}[/tex]

Now form the collision is completely elastic so the momentum before collision will be equal to after collision.

[tex]m_Av_A+m_Bv_B=(m_A+m_B)v_f[/tex]

[tex](2\times 5.94)+(3\times0)=(2+3)v_f[/tex]

[tex]v_f=\dfrac{11.88}{5}=2.376\ \frac{m}{s}[/tex]

Thus the speed of the blocks after the collision is most nearly will be Vf= 2.376 m/s.
