Answer:
4.5kg m^2 s−1
Explanation:
Step one:
the expression for angular momentum is given as
m = mass = 0.5kg
v = velocity = 7.5m/s
r = radius= 1.2m
Required
L = angular momentum
Step two:
substitute into the expression
L=0.5*7.5*1.2
L=4.5kg m^2 s−1
Answer is: balanced equation.
<span>Law of conservation of matter claims that in a</span>ny system that is closed to the transfer of matter, the amount of matter in the system stays constant.
Balanced equation states that <span>same number and type of atoms after the chemical reaction must present as before the chemical change.</span>
D = 110 m, t = 5 s
v o = 110 cs : 5 m = 22 m/s
-------------------------------------
v = v o - a t
v = 0 m/s, v o = 22 m/s, t = 4 s
0 = 22 - 4 a
4 a = 22
a = 22 : 4
a = 5.5 m/s²
g = 9.80 m/s²
9.80 : 5.5 = 0.56
Answer:
The magnitude of its acceleration is 5.5 m/s or 0.56 g.
The smaller the area the greater the pressure, while the bigger the smaller the pressure. So they are inversely proportional
