Answer:
Wavelength,
Explanation:
Given that,
Speed of the sound in the rat tissues, v = 1500 m/s
Let is the wavelength of an ultrasonic wave. The speed of a wave is given by the relation as follows:
Let us assume that the frequency of ultrasonic wave is 2.3 MHz.
So, the wavelength of an ultrasonic wave is . Hence, this is the required solution.
Answer:
Charge enter a 0.100 mm length of the axon is
Explanation:
Electric field E at a point due to a point charge is given by
where is the constant =
is the magnitude of point charge and is the distance from the point charge
Charges entering one meter of axon is
Charges entering 0.100 mm of axon is
substituting the value of in above equation, we get charge enter a 0.100 mm length of the axon is
When a rock is dropped from a bridge in this way, in terms of the magnitude of the acceleration and the speed of the rock as it falls, the best option is "<span>(1) Both acceleration and speed increase."</span>
Answer:
A) 2.09
B) -62.09°
Explanation:
If D = A+B+C then C = D - A - B
Converting both A and B to rectangular coordinates, we get:
A = [-4.07 , 4.68] and B = [6.19 , 3.87]
Replacing these values we can get the x and y components of C:
C = [0.98 , -1.85]
Its module is:
Its angle is:
