Answer:
<h2>Derived quantities are based on fundamental quantities, and they can be given in terms of fundamental quantities.</h2>
<h3>Fundamental quantities are the base quantities of a unit system, and they are defined independent of the other quantities. </h3>

Answer:
32.52 N
Explanation:
F-F' = ma.................. Equation 1
Where F = Force needed to pull the block, m = mass of the block, a = acceleration of the block, F' = Frictional force of the surface acting on the blcok
F = ma+F'
But,
F' = μmg
Where g = acceleration due to gravity, μ = coefficient of static friction
F = ma+μmg.................... Equation 2
Given: m = 6.0 kg, a = 1.5 m/s², μ = 0.40
Constant: g = 9.8 m/s²
Substitute these values into equation 2
F = 6(1.5)+6(9.8)(0.4)
F = 9+23.52
F = 32.52 N
Use the equation PV=nRT to find no. of moles (n)
For this;
At STP
Pressure= P= 1 atm
Temperature=T = 273.16 K
Volume= V= 16.3 L = 16.3 dm³
R = 0.0821 dm³ atm K⁻¹ mol⁻¹
Now,
PV= nRT
(1)(16.3)=n(0.0821)(273.16)
n = 0.727 mol
Now, again using the same equation for
Pressure=P= 735 torr
Temperature=T= 57°C
T= 57+273 =330 K
n= 0.727 mol (form previous calculation)
R= 62.4 dm³ torr K⁻¹ mol⁻¹
Now,
PV= nRT
(735)V= (0.727)(62.4)(330)
V= 20.37 dm³
Do you mean 12 km/h because this is a measurement of distance
Answer:
This structure can be viewed as consisting of six separate parts: (1) a nucleus, (2) a central bulge, (3) a disk (both a thin and a thick disk), (4) spiral arms, (5) a spherical component, and (6) a massive halo. Some of these components blend into each other. Three views of the Milky Way Galaxy.
