Your dog enjoys taking you for a walk. He pulls on his leash so that your feet start to slip. If your dog has a mass of 8kg and pulls you across the park at a constant speed of 0.8 m/s with a 20 N force, what is the coefficient of friction between your feet and the grass

in physics zero. in muscle fatigue could be high

does anyone know or what?

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.

false.

explanation:

this statement is false. after falling for 5 seconds, its speed will not be 100 m/s.
