Is there a picture that I can see
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.
I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
Answer:
10.347 minutes.
Explanation:
According to F = ma, she exerts force on camera of the magnitude
F = 0.67Kg*12m/
= 8.04N, assuming it took her one second to accelerate camera to 12m/s, then by newtons third law, which says every action has equal and opposite reaction , the camera exerts the same amount of force on the astronaut which gives her acceleration of a = 
.
and velocity of V = 0.1130801680m/s.
at this velocity , the astronaut has to cover the distance of 70.2 meters, it will take her 620.7985075s = 10.347 min to get to the shuttle (using S = vt).
Answer:
formed 4.6 billion years ago
orbit the Sun
range in size from a few feet to more than 500 miles across
most are found in the asteroid belt
Explanation:
Asteroids are rocky bodies orbiting the sun. Asteroids are irregular is shape and size. The size varies from few feet to 500 miles across. Majority of the asteroids lie in asteroid belt which lies between the orbits of Mars and Jupiter. These are though to be remains of unformed planet about 4.6 billion years ago due to high gravitational pull of Jupiter. The largest asteroid is Ceres which is also a dwarf planet. The mass of the entire asteroid belt is just 4% the mass of the moon.
Answer:
F = 69.3 N
Explanation:
For this exercise we use Newton's second law, remembering that the static friction force increases up to a maximum value given by
fr = μ N
We define a reference system parallel to the floor
block B ( lower)
Y axis
N - W₁-W₂ = 0
N = W₂ + W₂
N = (M + m) g
X axis
F -fr = M a
for block A (upper)
X axis
fr = m a (2)
so that the blocks do not slide, the acceleration in both must be the same.
Let's solve the system by adding the two equations
F = (M + m) a (3)
a =
the friction force has the formula
fr = μ N
fr = μ (M + m) g
let's calculate
fr = 0.34 (2.0 + 0.250) 9.8
fr = 7.7 N
we substitute in equation 2
fr = m a
a = fr / m
a = 7.7 / 0.250
a = 30.8 m / s²
we substitute in equation 3
F = (2.0 + 0.250) 30.8
F = 69.3 N
