Answer:
No you would not be an entrepreneur
Explanation:
An entrepreneur is someone who creates a business, and also organize the business affairs. The entrepreneur takes on the biggest financial risk.
It consists of a coil in a constant magnetic field. The current in the coil is the current being measured, and changes the magnetic moment of the coil (given by IA where I is current and A is loop area). This coil's magnetic moment feels a torque in this external magnetic field that moves a needle that tells the observer what the current must be, since the external field is known by the designers of the galvanometer.
<u>Given:</u>
Enthalpy of dissolution for NaOH = 44 kJ/mol
Mass of NaOH = 12.6 g
Mass of water = 250 g
Initial temperature of water T1 = 23 C
<u>To determine:</u>
The final temperature of water, T2
<u>Explanation:</u>
Molar mass of NaOH = 40 g/mol
# moles of NaOH = 12.6 g/ 40 g.mol-1 = 0.315 moles
Heat released during dissolution of 0.315 moles of NaOH=
= 44 * 0.315 = 13.86 kJ = 13860 J
Heat released by NaOH = heat absorbed by water
13860 = m*c*(T2-T1)
13860 = 250*4.18*(T2-23)
T2 = 36.26 C
Ans: The final temperature of water is 36.3 C
Answer:
139.11 m/s
0.000194287 Hz
5147.00596 s
Explanation:
= Wavelength = 716 km
s = Distance = 3130 km
t = Time = 6.25 h
Speed is given by
Speed of the wave is 139.11 m/s
Frequency is given by
The frequency is 0.000194287 Hz
Period is given by
The period is 5147.00596 s
Explanation:
Since the current flowing through an ideal capacitor is described by equation:
for voltage across the capacitor constant with time the current is:
Open switch has this characteristics (Constant voltage and zero current).
