Len [333]

Answer: have "cis C=C double bonds" and "liquid" at room temperature.

Explanation:

The unsaturated fatty acids have one or more C=C double bonds in the cis formation. Thus, this results in the molecules not been as stable as the saturated fats. They have weaker intermolecular bonds thus resulting in lower melting point . The consequently results in it being liquid at room temperature.

A box weights 50kg applies friction force of 125N. You apply a force of 150N going in the right direction. What is the total net

Pachacha [2.7K]

Answer:

Net force = 25N and in the right direction

Explanation:

mass of box, m = 50kg

Force of block = 150N

Friction force = 125N

$Net force = Force Applied - Friction force = F - F_f$

150 - 125 = 25N

the force applied to the block is greater than the friction force. there the force applied will overcome the friction force and move in the right direction of the force applied
