Answer:

Explanation:
Given the mass as M, the rotational inertia of the mower is;

-The roller doesn't slip while rolling;


The driver is tooling along in his snowmobile, pointed north,
at 8.5 m/s.
He's carrying the flares with him, so the flares are also moving north
at 8.5 m/s.
When he fires the flare straight up, it has a vertical velocity of 4.3 m/s
straight up, and a horizontal velocity of 8.5 m/s towards the north.
The magnitude of the net velocity is √(4.3² + 8.5²) .
That's about 9.53 m/s, at some angle between straight up
and straight north.
The angle above horizontal is the angle that has a tangent of 4.3/8.5 .
I'll let you work out the angle.
Answer:
carbon dioxide plays an important part in vital plant and animal process, such as photosynthesis and respiration.
Explanation:
Answer:
270 μA
Explanation:
Use the magnetic field due to long, straight wire and solve for current I.


plug in the values

= 2.7×10^{-4)×10^6
=270 μA
The current that flows in the heart is 270 μA
