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.
Answer:
AN electric current is required for an electric charge
Explanation:
Answer:
electric current=ampere(A)
force=Newton (N)
area=metres square(m^2)
power=watt(w)
density=kg/m3
amount of substance =mole per cubic meter (mol/m3).
volume=cubic meter (m3),
Answer:
Explanation:
The horizontal component of the velocity = 19.5 cos 36.5 = 15.67m /s
The vertical component = 19.5 sin36.5 = 11.6 m /s
height h = 15.5
we shall first find the time of fall of the ball into water
vertical displacement = height = 15.5 ( positive and g will be positive as it is downwards .
s = ut + 1/2 gt²
15.5 = - 19.5 sin36.5 t + 1/2 x 9.8 x t²
4.9 t² - 11.6 t - 15.5 = 0
t = 3.31 s
During this period ball will travel in horizontal velocity of 15.67 m /s uniformly
horizontal displacement before touching water
= 3.3 x 15.67
= 51.7 m .
The density is
(180) / (the volume of the lump in cm³) .
The unit of the density is grams/cm³ .
