Blaine steps into a ski slope with an angle of 25 degrees. there is a coefficient of kinetic friction of 0.15 between him and the ground. he has a mass of 65kg. questions:
1. write an expression for net force in the x and y directions. be sure to tilt your axis along the incline.
2. Calculate the net force and acceleration in the x- and y- directions.

I would really appreciate it if you can write the steps or at least the formula and the answer. ​

Astudent is performing an experiment comparing sound and light waves. the student gathers the following data. what conclusion does the student most likely make based on this data? light waves always travel the same speed; however, the speed of sound is determined by the medium that it travels through. all sound waves always have the same energy, so the temperature of the medium does not affect wave speed. light needs to vibrate particles, so it travels fastest in tightly packed solids, while sound does not need a medium, so it travels fastest in a gas. tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.

Which situation will have the highest resistance? a.long wire and high temperatureb.short wire and high temperaturec.long wire and cold temperaturedshort wire and low temperature

Why are graphs useful when interpreting data
