iren [92.7K]

Answer:

0.05 V/m

Explanation:

V = Potential difference that is possible for the dolphin to detect = 0.5 mV

d = Distance between electrodes = 1 cm

Electric field strength is given by

$E=\dfrac{V}{d}$

$\Rightarrow E=\dfrac{0.5\times 10^{-3}}{1\times 10^{-2}}$

$\Rightarrow E=0.05\ V/m$

The corresponding electric field strength is 0.05 V/m

What is the acceleration of the motorcycle in section CD?

jenyasd209 [6]

Answer:

30m/s²

Explanation:

The acceleration of the motorcycle in section CD is the slope of the velocity - time graph.

Given that;

Initial velocity = 20m/s Time = 6s

Final velocity = 50m/s Time = 7s

The time interval = 7s - 6s = 1s

So;

Acceleration = $\frac{Change in velocity }{time}$ = $\frac{50 - 20}{1}$ = 30m/s²

The color of bears, may be brown, black or white depending on how far North the bears are found.

Bears found close to the Arctic or North pole are white polar bears.

Based on the description of the house, every side of the home faces South meaning that the individual lives in the North pole.

If the period of a spring is 5 seconds what is the frequency

Scilla [17]

Answer:

C. 0.2 Hertz

Explanation:

The frequency of a spring is equal to the reciprocal of the period:

$f=\frac{1}{T}$

where

f is the frequency

T is the period

For the spring in this problem,

T = 5 s

therefore, the frequency is

$f=\frac{1}{5 s}=0.2 Hz$
