Answer:
0.692" arc sec.
Explanation:
Tan Ꝋ = Sin Ꝋ = ꝊR = 1.22 (Wavelength) / d
ꝊR = 1.22 x 550 x 10^-9m / 0.2m
= <em>3.355 x 10^-6 rad</em> x (3600 × 180) / π = 0.692" arc sec.
Answer:
The moment of inertia of the system is
Explanation:
From the question we are told that
The mass of the platform is
The radius of the platform is r = 1.95 m
The mass of the person is
The position of the person from the center is
The mass of the dog is
The position of the dog from the center is
Generally the moment of inertia of the platform with respect to its axis is mathematically represented as
The moment of inertia of the person with respect to the axis is mathematically represented as
The moment of inertia of the dog with respect to the axis is mathematically represented as
So the moment of inertia of the system about the axis is mathematically evaluated as
=>
substituting values
Answer:
13 meters
Explanation:
Step one:
given
We are told that Nathalie leaves a history classroom and walks 3 meters North
Then travels another 10 meters south to an art classroom.
Required
The total distance.
Step two:
The total distance can be computed by summing up the 3 meter North distance traveled and the 10 meter south distance traveled
Total distance= 3+10= 13meters
The answer would have to be 8.47 m/s/s because the backwards pull + the rate of speed it is going would have to be added to get the answer to compensate for the backwards pull
