Answer:
work done against friction: (a) if a body is moved horizontally against the frictional force this type of work is work done against friction.
(b) for example sliding a box and rolling a drum
work done against gravity: (a) if a body is moved vertically upwards against the gravity of the earth, this type of work is work done against gravity
(b) for example lifting and throwing of a body upward

(d) is the correct answer.
Answer:
B) Yes, ΔMNO ≅ ΔPON by SAS
Step-by-step explanation:
The Side Angle Side (SAS) postulate states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then these two triangles are congruent.
In this case, side MO is congruent to side NP and side NO is shared by both triangles. The included angle in ΔMNO is ∠O and in ΔPON is ∠N, and they are congruent.
5/15 in it's simplest form is 1/3
The triangle look late but you can bring it around
