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
We use the equation:
g = G m / r2
where
<span>G=constant universal gravitational = 6.67 x 10^-11 n m^2/kg^2 </span>
<span>m=planet mass=5.9736 x 10^24 kg (twice=11.9472) </span>
<span>r radium planet=6.372 km (twice=12.744)
</span>
<span>g= 6.67 x 10^-11 n m^2/kg^2 x 11.9472 10^24 kg/(12.744.000m)^2 </span>
<span>g=4.90 m/s^2 (1/2 of Earth gravity) <------- second option</span>
Answer:
first order date and most recent order date
Explanation:
it was switched. column 5 should be most recent order date because it's 2020 while column 6 should be first order date because it was in 2019
