Answer:
There are over 10 hazards or more at construction sites ,below are examples
Explanation:
1.Working at height.
2.Moving objects.
3.Slips, trips, and falls.
4.Noise.
5.Hand arm vibration syndrome.
6.Material and manual handling.
7.Collapsing trenches.
8.Asbestos.
9.Electricity.
10.Airborne fibres and materials.
The correct option is this: THE ATOMS IN THE SOLID WILL BE VIBRATING IN POSITION.
This is because the molecules in solids are held together by strong inter molecular forces, the molecules can not move about freely but they cab vibrate in their position.
Explanation:
As it is given that W = = 28.9 lbf
Mass is given as 30.0 lbm
Now, calculate as follows.
=
= 0.9633 lbf/lbm
Since, it is known that 1 lbf = lbm \times . Therefore, local gravity (g') will be calculated as follows.
=
Thus, we can conclude that the value of local gravity is .
Answer: A polar bond is a covalent bond between two atoms where the electrons forming the bond are unequally distributed. This causes the molecule to have a slight electrical dipole moment where one end is slightly positive and the other is slightly negative
Explanation:
For example like H & CL
<u>The three functions of the stem:</u>
- To support the leaves,
- To conduct water, and
- To conduct minerals to the leaves.
