This question deals with the volume of different shapes.
a) volume of the sphere is "33.51 m³".
b) volume of the cylinder is "25.13 m³".
a)
The volume of a sphere is given by the following formula:
<u>Volume = 33.51 m³</u>
<u />
b)
The volume of a cylinder is given by the following formula:
<u>Volume = 25.13 m³</u>
<u />

Answer:
-20v
Explanation:
Data provided in the question as per the given situation
L = 45 mH
f = 250 Hz
V_o = 20V
Based on the above information, let us assume voltage across inductor be V at t
So,
t = 2 ms
Now
The voltage at time t = 2.0 ms is
= -20 volt
= -20v
We simply solved the above equation so that the correct voltage could come
Answer:
The astronaut who has a mass of 80 kg without the toolkit do survive with 40 seconds of remaining air
Explanation:
Due the astronaut throws the 10-kg tool kit away with a speed of 8 m/s, it gives a momentum equivalent but in the other direction, so , then we can find the speed that the astronaut reaches due to its weight we get,
.
Finally, as the distance to the space shuttle is 200m, the time taken to the astronaut to reach it at the given speed will be , as the remaining air time is 4 min or 240 seconds, The astronaut who has a mass of 80 kg without the toolkit do survive with 40 seconds of remaining air.
