A graphical model of energy flow is an energy pyramid; The steps of the energy flow are
Producers: Green plants store solar energy as chemical energy after it being converted by photosynthesis.
Consumers: The are unable to produce food, they live on food produced by green plants.
Decomposers: some bacteria and molds break down the dead bodies of plants and animals step by step and turn them into simpler substances of dead plants and animals.
Answer:
Explanation:
the speed of the tsunami will be
v = distance / time
v = s/t
v = 2300 / 5.3
v = 434 miles/hour
To convert this to m/s, we should note that, 1 mile = 1609 m, and thus
434 miles/hr = 434 * 1609/3600
434 miles/hr = 194 m/s
The frequency, f is given by the formula
f = velocity * wavelength
f = vλ
f = 194 * 470
f = 91180 Hz = 91 kHz
Period, T = 1/f
Period T = 1.096*10^-5 s or
Period T = 1.096*10^-5 / 60
Period, T = 1.828*10^-7 minute
The volume of the sphere is given by V = 4/3 * pie * r^3. We seek dr/dt that the rate of change of the radius with respect to time.
V = 4/3 * pie * r^3
Since we know the rate at which the volume changes wrt time. We can plug it in to find dr/dt.
dV/dt = 36pie. But dV/dt = 4/3 * pie * 3r^2 * dr/dt
So we have that dr/dt = (dV/dt) / 4/3 * pie * 3r^2
So dr/dt = (36pie)/ 4/3 * pie * 3(4)^2
dr/dt = 113.112/ 201.0864 = 0.5624
number 1. is 223MHz number 3. is Each particle is a helium atom not an ion
Initial speed of walking = 1 m/s
Final speed of walking = 3 m/s
Change of speed in walking = (3 - 1) m/s
= 2 m/s
Time in which the change of speed occurred = 1 sec
Then
Acceleration = Change of Speed/ Time taken
= 2/1 m/s^2
= 2 m/s^2
So the correct option among all the options that are given in the question is option "A". I hope the procedure for finding the acceleration is clear to you and in future you can attempt such problems on your own and will required no help from outside.
