A205 kg log is pulled up a ramp by means of a rope that
isparallel to the surface of the ramp. the ramp is inclined at30%
with respect to the horizontal. the coeffecient ofkinetic frictin
between the log and the ramp is 0.900 and the loghas an
acceleration of 0.800 m/s2. find the tension in therope.

2.737 kN

Explanation:

Given

mass of log(m)=205 kg

ramp inclination

coefficient of kinetic friction between log and ramp is ()=0.9

log has an acceleration of 0.8 m/s^2

Let T be the tension in the rope

Where =Sin component of weight

(Where N is Normal reaction)

sin30=0.5

cos30=0.866

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !
