Answer:
primary advantage of composite material are high strength, low weight, corrosion resistance
Explanation:
The primary advantage of composite material is
1) high strength - they are stronger in strength than commanly used material like steel and aluminium.
2)low weight - lighter than most of the material like woods and others metals
3) corrosion resistance - it resist extreme condition of weather and can be good place where handling of chemicals takes place.
Answer:

Explanation:
We know the mass of the hole, so we define as,
kg
For which centripetal force is equal to gravitational force

Angular velocity is equal to v/r,

As r=1 and w=1, we clear to d,
m

Answer/Explanation:
They have a relatively small mass compared to Protons and Neutrons. Protons are electrochemically positive in charge and the Neutrons are electrochemically neutral in charge.
Answer:


Explanation:
Given that:
- mass of plank,

- length of plank,

From the image we can visualize the given situation.
Consider the given plank to be mass-less and having a uniformly distributed mass of 1.5 kg per meter.
<u>Now in the balanced condition:</u>

.......................(1)

...........................(2)
is the force acted by the tailgate on the plank.
<u>Substitute the value from (2) into (1):</u>
is the force acted by the wall upon the plank.
