Answer:
The angular velocity produced is 0.321 rad/s.
Explanation:
Given :
Diameter of space station , D = 190 m.
Therefore, radius , 
Also, acceleration , 
We know, angular velocity , 
.
Putting value of g and R in above equation.
We get ,
Hence, this is the required solution.
This question is incomplete; here is the complete question:
Marco is conducting an experiment. He knows the wave that he is working with has a wavelength of 32.4 cm. If he measures the frequency as 3 hertz, which statement about the wave is accurate?
A. The wave has traveled 32.4 cm in 3 seconds.
B. The wave has traveled 32.4 cm in 9 seconds.
C. The wave has traveled 97.2 cm in 3 seconds.
D. The wave has traveled 97.2 cm in 1 second.
The answer to this question is D. The wave has traveled 97.2 cm in 1 second.
Explanation:
The frequency of a wave, which is in this case 3 hertz, represents the number of waves that go through a point during 1 second. According to this, if the frequency of the wave is 3 hertz this means in 1 second there were 3 waves. Moreover, if you multiply the wavelength (32.4cm) by the frequency (3) you will know the distance the wave traveled in 1 second: 32.4 x 3 = 97.2 cm. This makes option D the correct one as the distance in 1 second was 97.2 cm.
The answer would be B.
Since the light source comes from the bottom, you just need to find the sequence from the bottom going up.
It will start with the light source, then go through the slide, which will then go through the objective lens and lastly, the eyepiece lens. In summary, the sequence is:
B. Light --- slide ---- objective lens --- eyepiece lens
Answer:
The correct option is B
Explanation:
In part A pressure is given as 
In Part B we can calculate the pressure using the formula
Where F is the force which in this case is weight which can be obtained as follow
W = Mg
Substituting 70kg for M and 
for g
A is the area with a value 
So substituting into the above equation
for part c
A 
F 
Therefore 
From this we see that the value of P for part B is the greatest
