A skier of weight 700 N is pointed down a ski hill that has a slope angle of 25° above horizontal. What is the component of his weight pulling him down the slope.
O 634N
O 326N
O 296N
O 700N

O 296N

Explanation:

F_y = F*sin(x)

F_y = 700N*sin(25°)

F_y = 295.83N or 296N

296 N

Explanation:

F=700 x sin(25)

F= 296 N

0.11 m/s and 0.28 m/s should be correct

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
