<span>Make the surfaces smoother. Rough surfaces produce more friction and smooth surfaces reduce friction
Lubrication is another way to make a surface smoother
Make the object more streamlined
Reduce the forces acting on the surfaces

No, because the energy is the capacity for performing work. Gravity is the force that draws everything to the earth's center.
Answer:
Photosynthesis is the pocess by which green plants make their own food.
b. sunlight, glucose, water, altra-violet ray as catalyst
The resultant force of both forces is 15.62 N.
<h3 /><h3>What is resultant?</h3>
The Resultant of forces is a single force obtained when two or more forces are combined.
To calculate the resultant of the force, we use the formula below.
Formula:
- R = √[a²+b²-2abcos∅]..................... Equation 1
Where:
- R = Resultant of the forces.
- ∅ = Angle between both forces
From the question,
Given:
Substitute these values into equation 1
- R = √[8²+10²-2×8×10cos120°]
- R = √[64+100-160cos120°]
- R =√ [164-160(-0.5)]
- R = √[164+80]
- R = √(244)
- R = 15.62 N
Hence, the resultant force of both forces is 15.62 N.
