Trees. Every time the wind blows there is a wave of motion which is movement

Answer:

The wavelike motion usually can be described by the equation:

X(y,t) = Acos(kx - wt) + Bsin(kx - wt), so wavelike motion is usually a periodic motion.

Where k is the wavenumber and w is the frequency.

You can see a wavelike motion in trees when the wind moves them and the branches start to move in oscillatory motion.

Another example of wave motion can be some fishes, that use wavelike motion to impulse in the water.

Another example can be the Vipera ammodytes that move in a wavelike motion, with the objective of increasing its speed and agility in the sand.

Blizzard [7]

Answer:

power output = 30730.71 kJ/s

Explanation:

given data

pressure p1 = 10 MPa

temperature = 500° C

pressure p2 = 10 kPa

quality = 50.027 % = 0.50027

mass flow rate m = 15.469

to find out

power output in MW

solution

we know energy balance equation here that is

Energy (in) = Energy (out)

mh1 = P(out) + mh2

P(out) = - m ( h2 - h1) .................1

we know here h1 from steam table that is

h1 = 3375.1 kJ/kg and

hf = 191.81 and hfg = 2392.1 kJ/kg

h2 = hf + quality hfg

h2 = 191.81 + 0.50027 (2392.1) = 1388.50 kJ/kg

so from equation 1 we get power output

P(out) = - m ( h2 - h1)

P(out) = - 15.469 ( 1388.50 - 3375.1 )

power output = 30730.71 kJ/s

baherus [9]

Answer:

0.85V

Explanation:

The emf is calculated by using the Lenz's Law

$\epsilon=-\frac{\Delta\Phi_B}{\Delta t}$

But for this case we have that the magnetic field is constant. Hence we have

$\epsilon=-\frac{B(A_{2}-A_{1})}{t_2-t_1}=-\frac{(1.10T)(0.270m^{2}-0.89m^{2})}{0.8s}\\\\\epsilon=0.85V$

where we have taken that the intial time is t1=0

I hope this is useful for you

Question 1.

mass = 4500 kg
potential energy (p.e) = 67500 J

now, we know :

=》

$p.e = mgh$

=》

$67500 = 4500 \times 10 \times h$

=》

$67500 = 45000 \times h$

=》

$h = \dfrac{67500}{45000}$

=》

$h = 1.5 \: m$

note : if we take acceleration due to gravity as 9.8, then height = 1.53 m

Question 2.

mass = 4500 kg
kinetic energy = 63000 j

we know,

=》

$k.e = \dfrac{1}{2} mv {}^{2}$

=》

$63000 = \dfrac{1}{2} \times 4500 \times {v}^{2}$

=》

${v}^{2} = \dfrac{63000 \times 2}{4500}$

=》

${v}^{2} = 28$

=》

$v = \sqrt{28}$

=》

$v = 2 \sqrt{7} \: \: ms {}^{ - 1}$

=》

$5.29 \: \: ms {}^{ - 1}$
