Awaitperson carrying a tray with a platter on it tips the tray at an angle of 12 degrees below the horizontal. if the gravitational force on the platter is 5.0 n, what is the magnitude of the force parallel to the tray that tends to cause the platter to slide down the tray?

1.04 N

Explanation:

Given

Gravitational Force on the Platter is

Tray makes an angle of

This gravitational Force has components along and Perpendicular to Platter

Perpendicular Force

Along the Tray

Thus 1.04 N is the magnitude of force that will cause Platter to slide down  

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6

double the distance = divide strength by 4
