Answer:
-8
Explanation:
sea level is another way of saying zero. If something is above or above sea level it is a positive integer. like a regular number. if something is below sea level it is a negative integer like negative numbers. They said 8 is the elevation but new orleans is BELOW sea level. that means the integer we are looking for is going to be a negative number. 8 is the number they told us and since it is below the sea level. The integer of new orleans that represents its elevation is -8.
Answer: the child's centripetal acceleration=24.50 m/s²
Explanation:
Given that mass of child= 50 kg
radius of merry go round= 2.25m
angular speed = 3.30 rad/s
Centripetal Acceleration = v²/ r
But V= ωr
So Centripetal Acceleration = v²/ r = (ωr)²/ r
=(3.30)² x (2.25)²/ 2.25 = (3.30)² x 2.25
=24.5025m/s²
=24.50 m/s²
<span>Speed (rms) = sqrt 3KT/m, where:
K = Boltzmann's costant = 1.38*10^-23 joule/K;
T = temperature in Kelvin degrees = 273 - 63 = 210 K;
m = 44 * 1.672*10^-27 Kg;
1.672*10^-27 Kg (good approximation) is the weight of a single a.m.u. (atomic mass unit);
44 is molecular weight of CO2.
Molecular Speed (CO2) = sqrt 3*1.38*10^-23*210/44*1.672*10^-27 = 344 m/sec.

The total resistance in the circuit, R is 4 Ω .
The meters connected to the 12 Ω resistance are:
- Voltmeter - connected in parallel
- Ammeter - connected in series
If the switch is opened, only the 4 Ω and 2 Ω resistances will stop working.
<h3>What is the equivalent or total resistance in the circuit?</h3>
The resistances in the circuit are connected both in series and in parallel
The resistances in series are the 4 Ω and the 2 Ω resistances.
Equivalent resistance = 4 + 2 = 6 Ω
The 4 Ω and the 2 Ω resistances are then connected in parallel with the 12 Ω resistance.
Total resistance, R is calculated as follows:
1/R = 1/12 + 1/6
1/R = 3/12
R = 12/3
R = 4Ω
The meters connected to the 12 Ω resistance are:
- Voltmeter - connected in parallel
- Ammeter - connected in series
If the switch is opened, only the 4 Ω and 2 Ω resistances will stop working because the circuit connecting them to the cell is broken whereas the circuit to the 12 Ω resistance is continuous.
In conclusion, resistances can be connected in parallel or in series.
