Answer /The wave with frequency 100 will have its crests farther apart as its wavelength Will be more or elevated.

Explanation:

For sound waves, the velocity ‘v’ is equal to the product of wavelength (λ) and frequency (f) i.e. (v = n × λ or v/n = λ). Therefore, frequency is indirectly proportional to the wavelength.

The sound wave with frequency 100 will have its crests farther apart from each other as frequency is indirectly proportional to the wavelength. The speed of a wave is uninfluenced by variation in the frequency. Therefore, the less frequency wave will have more wavelength.

Explanation:

The more focused the rays are, the more energy an area receives, and the warmer it is.

The average velocity of the whole journey will be total distance covered divided by the total time. It will be approximately equal to 8 m/s. The right answer is option B

Velocity is the distance travelled in a specific direction. While the average velocity of the whole journey will be total distance covered divided by the total time

When driving a Toyota avensis car along a straight road for 16.5km at

50km/h,

The velocity = 50 km/h

Distance = 16.5 km

Use the speed formula to calculate time.

Speed = distance / time

Time = distance / speed

Time = 16.5 / 50

Time = 0.33 s

If over the next 20min, you walked another 2.5km further along the road for a petrol station, Then,

average velocity = Total distance covered divided by total time taken.

Where

The time t = 20/60 = 0.333 h

Total time = 0.33 + 0.3333

Total time = 0.6633333

Total distance = 16.5 + 2.5

Total distance = 19 km

Average velocity = 19 / 0.66333

Average Velocity = 28.64 km/h

Now convert Km/h to m/s

(28.6432 x 1000) / 3600

286432 / 3600

7.956m/s

Therefore, the average velocity of the whole journey from beginning of the drive to the arrival at the filling station will be approximately 8 m/s

Answer:It is known that geothermal vitality has numerous preferences compared with sun oriented and wind frameworks. These points of interest incorporate climate confirmation, base stack, incredible steadiness, and tall warm effectiveness. The entire introduced capacity of geothermal power, be that as it may, is much less than sun powered and wind.

Answer:

The amount of sunlight received depends on time of day and weather. So, the amount of solar energy produced can be inconsistent. However, heat flows out of Earth all the time, so the supply of geothermal energy is more reliable and consistent.

Answer:

1200000 J or 12x10^5 J

Explanation:

Work = force * distance, so using that:

Note: Distance has to be in meters
W = 800 * 1.5x10^3

W = 1200000 J

The work done while pushing a crate across a level floor for a distance of 1.5km would be 1200 Kilojoules.

The total amount of energy transferred when a force is applied to move an object through some distance

Work Done = Force * Displacement

As given in the problem we have to calculate how much work is done when a force of 800.0 Newtons  is exerted while pushing a crate across a level floor for a distance of 1.5 kilometers,

1 kilometers = 1000 meters

1.5 kilometers = 1500 meters

Work done on pushing a crate = force ×displacement

                                                    =800.0 ×1500

                                                     =1200000

                                                    =1200 Kilojoules

Thus, the work done would be 1200 Kilojoules.

Hi there!

Assuming the pulley is frictionless and massless, we can do a summation of forces for each block.

Block 1 has the tension force (in direction of acceleration) and force of static friction acting on it. For the block to be stationary, the net force must be 0, so:
[tex]\Sigma F = T - F_S[/tex]

[tex]0 = T - F_S\\\\T = F_S[/tex]

Now, we can do a summation for Block 2.

[tex]\Sigma F = W_2 - T\\\\0 = W_2 - T\\\\T = W_2[/tex]

We can substitute this tension in the above equation to solve for the force of static friction and the coefficient of static friction.

[tex]F_S = W_2\\\\\mu m_1g = m_2g\\\\\mu = \frac{m_2}{m_1} = \boxed{\mu = .2}[/tex]

The length of the inclined plane is approximately 12 ft

The situation forms a right angle triangle.

Right triangle have one of its angle as 90 degrees.

Therefore,

The length of the inclined plane is the hypotenuse of the triangle. The length of the inclined plane can be found using trigonometric ratios.

height = 4 ft

angle(∅) = 19.45°

sin 19.45 = 4 / h

h = 4 / 0.33298412235

Question:

A piece of rubber 10cm long stretches from 6mm when a load of 100N is hung from it. What is the strain?

Important Note (for solving your any problems):

In Physics to help for better understanding, it is important to write out

your given first.Given:

1. Original length = 10cm 2. Extension e= 6mm

3. The extension is meant to be in cm and to convert mm to cm, divide the number by 10.

Answer:

Strain = 0.6

Explanation:

Solution:

Remember that,

[10 mm = 1 cm]

6 mm = (6 × 1) ÷ 10

-

= 0.6 cm

Load (force) = 100N

Recall that,

Strain = (extension) Original length

Strain = 0.6 cm ÷ 10 cm

Strain = 0.06

If you convert to standard form,

0.06 = 6 x 10^-2
