Answer:
On Edg 2021, the answer was "B = The moon's orbital period and distance from Earth"
Explanation:
I hope this is correct for you, if it isn't I am very sorry. Good luck! :)
Answer:
291 K
Explanation:
To convert Celcius to Kelvin all you have to do is add 273 because 0 Celcius is equal to 273 K.
18 + 273 = 291
Answer:
A. 2.83 m/s
B. 39.55 degrees north of east
Explanation:
The velocity of the ball relative to the ground is the sum vectors of velocity of the ball relative to Mia and the velocity of Mia relative to the ground
If we take north east as positive direction then
Velocity vector of the ball relative to Mia is
Velocity of Mia relative to gorund is
<0, 5.3>
So velocity of the ball relative to the ground is
<1.8, -3.12> + <0, 5.3> = <1.8, 2.18>
Its magnitude is:
m/s
Its direction is
north of east
Answer:
Explanation:
The speed is 0.7 m/s.
The distance covered is 1609 m.
Multiplying both sides by <em>t</em>.
Then dividing both sides by 0.7.
It would take 2298.57 seconds.
Answer:
Viscosity of the fluid is
Explanation:
Given
- Length of the concentric cylinders, L=75 cm
- Gap between two concentric cylinders = 1 mm
- The frequency of inner cylinder = 300 rpm
- Torque acting
- Outer diameter of the inner cylinder=15 cm
The Area is given by
The velocity of the layer is layer is given by
Force acting by one layer of the fluid to other is given by F
Now from the Law of viscosity we have
Hence the viscosity of the fluid is
