Answer:
The answer to your question is given below
Explanation:
From the question given above, we can see that the wave with a higher frequency has a shorter wavelength while that with a lower frequency has a longer wavelength. This is so because the frequency and wavelength of a wave has inverse relationship. This can further be explained by using the following formula:
Velocity = wavelength x frequency
Divide both side by wavelength
Frequency = Velocity /wavelength
Keeping the velocity constant, we have:
Frequency ∝ 1 / wavelength
From the above illustration, we can see clearly that the frequency and wavelength are in inverse relationship. This implies that the higher the frequency, the shorter the wavelength and the shorter the frequency, the higher the wavelength.
Answer:
Explanation:
A representative does his/her utmost to convey the feelings of the majority of the group they speak for, and stands up for their interests. This might be for negotiation, voting, litigation, diplomacy, etc.
A leader, ideally, inspires their constituents and brings out the best in them, as in strength, ethics, spirituality, and so on.
Short version: a rep is an agent or conduit. A leader is a catalyst. Either job can be hard. And yes, it can be done for most of a population. Maybe not all, but not everyone can fit into the same mold.
<span>The correct answer is A: True. Although the ability to forecast weather has increased over the years, the ability to predict when and how much wind will occur at any given time and place is difficult. Weather conditions are subject to constant change and while some areas are known to have more wind than others, there is no guarantee about how much wind there will be as weather patterns vary in consistency.</span>
Imagine a right triangle where the legs represent the horizontal and vertical lengths of the string and the hypotenuse represents the length of the string.
Let us assign some values:
x = horizontal length in feet
50 = vertical length in feet
L = length of the string in feet
Because we are modeling these quantities with a right triangle, we can use the Pythagorean theorem to relate them with the following equation:
L² = x² + 50²
We want to find an equation for the change of L over time, so first differentiate both sides with respect to time t then solve for dL/dt:
2L(dL/dt) = 2x(dx/dt)
dL/dt = (x/L)(dx/dt)
First let's solve for x at the moment in time described in the problem using the Pythagorean theorem:
L² = x² + 50²
Given values:
L = 100ft
Plug in and solve for x:
100² = x² + 50²
x = 86.6ft
Now let's find dL/dt. Given values:
x = 86.6ft, L = 100ft, dx/dt = 4ft/sec
Plug in and solve for dL/dt:
dL/dt = (86.6/100)(4)
dL/dt = 3.46ft/sec
Answer:
6 climate regions are Mediterranean, Polar, Tropical, Temperate, Arid and Tundra.
Explanation:
There are six main climate regions in the world. These regions distinguished from one another on the basis of climate that exists there. Above mentioned climates are described shortly as follows:
Mediterranean: This region is the region surrounding the Mediterranean sea, Southern California and Southern America. The climate in this region is hot and dry in summer whereas mild winters are there in this region.
Polar: This region is on the South Pole, near the side of Greenland. The climate in this region is very cold and chilled.
Tropical: This region consists of jungles of South America, Africa, some parts of Asia and the islands of Pacific. The climate of this region is Hot. Due to heavy rainfalls in this area, the area is also wet.
Temperate: North America, Europe and Northern Asia is included in this region. The climate is mild hot in summers and cold in winters.
Arid: This region consists of deserts of Africa, Asia, US and Australia. The climate is very hot throughout the year.
Tundra: This region consists of the mountain tops of America, Asia and Greenland. The climate is extremely cold in such regions throughout the year.
