Boy X and Boy Y both move backward in opposite directions.
Answer:
LHS=RHS=[L]
Explanation:
Given mathematical expression:
where: dimension:
s = displacement length
u = initial velocity
t = time
a = acceleration
now using dimensional analysis:
we know that the ratio and constants have no dimension.
as we know that only similar dimensions can be added or subtracted therefore we get a correct conclusion.
<em>However we can deduce the operators between the equations and can neither check for the validity of the constants. We can only check for the dimension of the terms involved.</em>
KE = PE
Work done = PE = KE
Wd = force * distance
Force = m.a
Distance = s
But a = v -u/t
v = final velocity
u = initial velocity
t = time
s = (t)(u + v)/2
KE = body starts from rest
Wd = m * (v-u/t) * (t)(u+v)/2
Wd = m * (v-0/t) * (t)(0+v)/2
Wd = m * (v-0) * (0+v)/2
Wd = m * (0 + v^2 - 0 + 0)/2
Wd = m * v^2 /2
Wd = 1/2 mv^2
Therefore if h=PE/(12000kg * 9.8m/s^2)
And PE=KE
h=5400000J/117600kgms^2
h=45918367.3m2/s4
Answer:
The correct answer would be downwards
Hope this helps have a good day
a. a gradual approximation to the final solution
Explanation:
Means/end analysis is a process that involves creation of an end goal to enable the identified means to apply.
In this techniques sub-goals are formed to eliminate the challenges faced in application of a selected operator.
It starts by identifying a predetermined goal which is followed by actions that will led to the goal.
