6 0

Answer: the loneliest whale relates to the communication that whales give to each other

Explanation: whales have different forms of communication , and the ‘loneliest’ whale can’t get any company by the other whales.

In other words: it may be a new and different way whales communicate, nobody knows much about the loneliest whale. It may be forming a new kind of communication

Answer:

Explanation:

still water speed is 50 m / 25.0 s = 2.00 m/s or 200 cm/s

In lane 1 the effective speed would be 201.2 cm/s

5000 cm / 201.2 cm/s = 24.85 s

The change is 25.00 - 24.85 = 0.15 s decrease in time

In lane 8, the effective speed would be 198.8 cm/s

5000 cm / 198.8 cm/s = 25.15 s

The change is 25.00 - 25.15 = 0.15 s increase in time

Answer:

<h2>Magnetic field strength in that region is 1.2 T</h2>

Explanation:

As we know by the formula of radius of charge moving in external field is given as

$R = \frac{mv}{qB}$

so we will have

$R = 25 cm$

$m = 1.6 \times 10^{-27} kg$

$q = 1.6 \times 10^{-19} C$

$v = 0.10 \times 3 \times 10^8 m/s$

now we have

$0.25 = \frac{(1.6 \times 10^{-27})(3\times 10^7)}{(1.6 \times 10^{-19})B}$

now we have

$B = 1.2 T$

What is the source of geothermal energy? User: What is the source of geothermal energy?

bazaltina [42]

The answer is; C

In particular points in the earth’s surface, underground water is naturally heated to steam that can be harness for geothermal energy. The steam that ejects from the ground with high kinetic energy can be used to turn turbines that generate electricity. The underground water is usually heated by the hot rocks beneath that are subjected to the immense heat of magma or the enormous pressure of overlying crust.

A particle's position along the x-axis is described by. x(t)= At+Bt^2where t is In seconds: x is in meters: and the constants A

DanielleElmas [232]

Answer

given,

position of particle

x(t)= A t + B t²

A = -3.5 m/s

B = 3.9 m/s²

t = 3 s

a) x(t)= -3.5 t + 3.9 t²

velocity of the particle is equal to the differentiation of position w.r.t. time.

$\dfrac{dx}{dt}=\dfrac{d}{dt}(-3.5t + 3.9t^2)$

$v= -3.5 + 7.8 t$ ------(1)

velocity of the particle at t = 3 s

v = -3.5 + 7.8 x 3

v = 19.9 m/s

b) velocity of the particle at origin

time at which particle is at origin

x(t)= -3.5 t + 3.9 t²

0 = t (-3.5 + 3.9 t )

t = 0, $t=\dfrac{3.5}{3.9}$

t = 0 , 0.897 s

speed of the particle at t = 0.897 s

from equation (1)

v = -3.9 + 7.8 t

v = -3.9 + 7.8 x 0.897

v = 3.1 m/s
