Using a scale of 1 cm to represent 10 N, find the size and direction of the resultant of forces of 50 N and 30 N acting at the angle of 45 O to each other.

Explanation:

P = 50 N

Q = 30 N

= Angle between the vectors =

Resultant is given by

Angle of resultant

Magnitude of the resultant is

Direction of the resultant is

explanation:

as the height from which the ruler was dropped increased, the speed of the ruler at ryan's hand increased.

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.
