Answer:
1500 m/s
Explanation:
Recall that for a wave,
Speed = frequency x wavelength
here we are given frequency = 500 Hz and wavelength = 3m
simply substitute into above equation
Speed = 500 Hz x 3m
= 1500 m/s
Answer:
1/8 x C
Explanation:
The capacitance of parallel plate capacitor
= ε₀ A /d where A is area of plate and d is distance between plate.
for capacitor 1
C = ε₀ A /d
For capacitor 2
radius = R/2
Area = A / 4
Capacitance
= ε₀ (A/4) x ( 1 / 2d )
= ( 1 / 8) x (ε₀ A /d)
= 1/8 x C
Answer:
The word Allopatric is derived from the Greek words allos = other and Patris = fatherland. Allopatric specification happens when the biological population of the same specie got separated from one another such that it stopped their gene flow or gene migration. It happens due to the geographical changes such as the movement of continents, changes in glaciers, mountains or oceans and it could be happened because of human activities like agriculture and industrial development etc. The first step of Allopatric specification is Geographical isolation. The species got separated and the long distances makes them unable to interbreed.
To solve this problem we simply need to apply the concepts of energy conservation.
Let us break down the problem by the steps suggested by the statement:
For the first step we have to
Where Q is heat absorbed and W the work done
For the second step we have to
Therefore the change in internal energy for entire process is 62J
