Answer:
When radius of star increase by 6 factor then area of star will increase by a factor of 36.
Explanation:
As we know that
Area of star A given as
Where R is the radius of star.
Area of star when radius become 6 times
So
We can say that when radius of star increase by 6 factor then area of star will increase by a factor of 36.
The above given sentence is true reason being the use of Technology.
Explanation:
The basic purpose double technology is to make hard work easier and help in meeting the needs. Technology was being developed and is being upgraded so as to make some of the tasks, which were harder to do without it, easier.
Development of Technology has made the work easier and the needs are being met with an additional profit of saving time.
Answer:
The new energy density is same as initial energy density u0 as it is independent of plate dimensions
Explanation:
As we know that energy density is total energy per unit volume
so we know that isolated plates of capacitor is placed here
here we have energy density given as
so we have
so it is independent of the dimensions of the plate while total charge on the plates is constant always
so energy density will not change and remains the same
27. 20,000 hertz
28. A stream of photons
29. Either infrared or gamma
The tiger's position at time <em>t</em> is given by
<em>x</em> (horizontal) = (4.5 m/s) <em>t</em>
<em>y</em> (vertical) = 7.5 m - 1/2 <em>gt</em> ²
Solve <em>y</em> = 0 for <em>t</em> to find the time it takes for the tiger to reach the ground :
0 = 7.5 m - 1/2 (9.8 m/s²) <em>t</em> ²
===> <em>t</em> = √(2 (7.5 m) / (9.8 m/s²)) ≈ 1.2 s
Evaluate <em>x</em> at this time :
<em>x</em> = (4.5 m/s) (1.2 s) ≈ 5.6 m
