Answer:

I will say that no 1 is incorrect

Explanation:

no 1 is incorrect because one person cant confidently and effectively carry out an investigation there should be a collective work so that when ever there is a mistake and the one leading does not notice it the sub ordinates will and it will be corrected

Answer:

so the speed will increase by 1.44 times then the initial speed if the distance is increased to double

Explanation:

As we know that the air friction or resistance due to air is neglected then we can use the equation of kinematics here

$v_f^2 - v_i^2 = 2 a d$

since we released it from rest so we have

$v_i = 0$

so here we have

$v_f = \sqrt{2gd}$

now if the distance is double then we have

$v_f' = \sqrt{2g(2d)}$

now from above two equations we can say that

$v_f' = \sqrt2 v_f$

so the speed will increase by 1.44 times then the initial speed if the distance is increased to double

Which quantity and unit are INCORRECTLY paired?

liq [111]

Force, the unit is Newton, newton is the force to accelerate a mass. so it should be kg m/s^2

joule (J) is equal to Nm not Ns

the unit of work is J and it is correct.
the unit of power is J/s which is equal to W
the unit of of energy is the same with work, which is J which equivalent to kgm2/s2

Speed x time = distance
Distance divided by time = speed
500 divided by 5
Speed = 100
