Answer:
Cinder blocks
Explanation:
From safety training guides, whenever there is inadequate support, poor
construction, or a movement in the components of the
scaffold such as the coupler as well as the base upon which the
scaffold structure is built, there will be a great danger of collapse.
In light of this safety rule, Cinder blocks such as sandcrete blocks, bricks e.t.c shouldn't be used to support scaffold because they
have a high tendency of being crushed under load
Answer:
8.8 cm
31.422 cm/s
Explanation:
m = Mass of block = 0.6 kg
k = Spring constant = 15 N/m
x = Compression of spring
v = Velocity of block
A = Amplitude
As the energy of the system is conserved we have
Amplitude of the oscillations is 8.8 cm
At x = 0.7 A
Again, as the energy of the system is conserved we have
The block's speed is 31.422 cm/s
It is an extension of the grounding system
A. Energy was used to change phase of water from liquid to gas (evaporation). it is radiated back into the atmosphere from the stove.
This is because water evaperates after reaching it's boiling point.
