Answer:
113.7
Explanation:
maximum distance (s) = 8.9 km
reference intensity (I0) = 1 x 10^{-12} W/m^{2}
power of a juvenile howler monkey (p) = 63 x 10^{-6} W
distance (r) = 210 m
intensity (I) = power/area
where we assume the area of a sphere due to the uniformity of the output in all directions
area = 4π
= 4π x 
= 554,176.9 m^{2}
intensity (I) = 
therefore the desired ratio I/I0 = 
= 113.7

Answer:
Balloon
Explanation:
it inflates because of the air pressure inside
Question: In which situation would a space probe most likely experience centripetal acceleration?
as it revolves around a planet
as it flies straight past a moon
as it is pulled in a line toward the Sun
as it lifts off from Earth
Answer:
When "space probe revolves around a planet" most likely to experience centripetal acceleration
Explanation:
Centripetal acceleration defined as the rate in change of tangential velocity. Also, as per Newton's second law, any kind of force will be directly proportional to the acceleration attained by the object. So, for centripetal acceleration, the force will be the centripetal force. The centripetal force will be acting on an object rotating in a circular motion with its direction of force towards the center. Thus, centripetal acceleration will be experienced by an object or a space probe when it is in a circular motion. It means the space probe is revolving around a planet.
Answer:
1.00029
Explanation:
A wave is a disturbance which travels through a medium and transfers energy without displacing the medium itself.
interference is one of the characteristics of a wave motion
The Michelson interferometer produces interference fringes by splitting a beam of monochromatic light so that one beam strikes a fixed mirror and the other a movable mirror. When the reflected beams are reflected, an interference pattern results.
∝Δm=Δud
∝=wavelength 500nm
Δm=number of fringes
d=length 9f the Michelson interferometer chamber
Δu= change in refractive index
500*10^-9*29=0.05*Δu
Δu=0.00029
REFRACTIVE INDEX=1+0.00029
refractive index=
1.00029
