AMA is actual mechanical advantage in where it would compare the force in as well as out in using actual measurements in the real life or with friction while in IMA which is the ideal mechanical advantage no friction then is needed. The answer then is a. the value of IMA is larger than AMA.
a = Δv ÷ t
t = 5 seconds
Δv = v2 - v1
v2 = 0 m/s
v1 = 54 ÷ 3.6 = 15 m/s ----> a = (0 - 15) ÷ 5 = -15 ÷ 5 = -3 m/s²
Answer:
Q1: (a)
so
Q2:
this is the radius in meter
diameter = 2r
in this i don't know which choice is the right answer
Q3:
so
again there is no correct answer
A good way to do that is to talk abt anything, TALK MORE NOT LESS:)
Answer:
where
Pa = Gravitational potential energy of satellite A
Pb = Gravitational potential energy of satellite B
G = gravitational constant
Me = Mass of the earth
Ma = Mass of satellite A
Mb = Mass of satellite B
Re = Radius of the earth
Pb/Pa = (-GMeMb/Re) / (-GMeMa/Re)
Pb/Pa = Mb/Ma
