Answer:
Because they would naturally dye the test strips in the colors violet and red, regardless of their pH values

5.8 moles of nitrogen gas are needed to pressurize the air bag.
<h3>What's the expression of Ideal gas equation?</h3>
- Ideal gas equation is PV=nRT
- P= pressure, V = volume, n= no. of moles of gas, R= universal gas constant, T = temperature of the gas
<h3>What's the no. of moles of nitrogen present in a 60L air bag at 2.37 atm pressure and 25°C temperature?</h3>
- P= 2.37 atm, V = 60L, R= 0.0821 L-atm/mol-K, T = 25°C = 298K
- n= PV/RT
= (2.37×60)/(0.0821×298)
= 5.8 moles
Thus, we can conclude that 5.8 moles of nitrogen gas are needed to pressurize the air bag.

Answer: A (Ft)
Explanation: The impulse experienced by the object equals the change in momentum of the object. In equation form, F • t = m • Δ v
Drinking water helps maintain nearly all processes of the human body and <em>homeostasis. </em>Further, drinking water helps,
- Digestion
- Absorption
- Circulation
- Saliva and mucus production
- Thermoregulation/homeostasis
- Lubrication of joints
- Boosts integumentary health.
- Helps in excretory systems
- Prevents dehydration of cells
- Reduces chance of hangover from alcoholic drinks.
- etc,
Succinctly, it is VERY important to drink water! Water is the source of human life and without water, we cannot survive.
Answer:
option (c)
Explanation:
Fundamental frequency of segment A = f
Second harmonic frequency of B = fundamental frequency of A .
Tension in both the wires is same and the mass density is also same as the wires are identical.
fundamental frequency of wire A is given by
.... (1)
Second harmonic of B is given by
.... (2)
Equation (1) is equal to equation (2), we get
So, LB = 2 L
Thus, the length of wire segment B is 2 times the length of wire segment A.
