Answer:
59cm
Explanation:
angular velocity = 0.8 rad/s
linear velocity = angular velocity * radius
=0.8rad/s * 5m
= 4 m/s
wavelength = (V + U)/F
where,
V is the velocity of the wave
U is the velocity of the source
F is the frequency of the source.
wavelength = (350 m/s + 4 m/s ) / 600 Hz
Wavelength = 0.59m or 59 cm
Answer:
D) accelerate but will not spin.
Explanation:
On the off chance that there is no air resistance the object will accelerate yet won't turn, this is on the grounds that without air resistance same force is applied on each bit of the object. Force on each segment is coordinated descending i.e parallel force. So there is no force to deliver spin movement in it.
It will accelerate because of gravity
Step 2: calculate A and B magnitudes
Step 3: calculate x, y components
Step 4: sum vector components
Step 5: calculate magnitude of R
Step 6: calculate direction of R
Answer:
wipe the area that came into contact with the electrodes with an alcohol pad
Explanation:
According to my research on the procedure for iontophoresis, I can say that based on the information provided within the question the OTR should wipe the area that came into contact with the electrodes with an alcohol pad. This is because the alcohol pad kills any bacteria that is lingering on the skin and therefore prevents infections from occurring. Especially since the iontophoresis procedure can increase skin permeability which makes it easier for infections to arise.

As we know that
here we know that
now from above equation we have
