Answer:
14.36 N
Explanation:
= Tension in string 1
= Tension in string 2
= mass of the bar = 2.7 kg
= weight of the bar
weight of the bar is given as
N
= mass of the bar = 1.35 kg
= weight of the monkey
weight of the monkey is given as
N
Using equilibrium of torque about left end
N
Using equilibrium of force in vertical direction
N
Answer:
49.82414 atm
50.74675 atm
Explanation:
P = Pressure
V = Volume = 5.45 L
R = Gas constant = 0.08205 L atm/mol K
T = Temperature = 25°C
a = 0.211 atm L²/mol²
b = 0.0171 atm L²/mol²
From ideal gas law we have

The pressure is 49.82414 atm
From Van der Waals equation we have

The pressure is 50.74675 atm
Answer:
A. the frequency decreases.
Explanation:
The wavelength of electromagnetic radiation depends on the speed of radiation and the frequency of the radiation.
The speed of the radiation is equal to the speed of light and is given as the product of its frequency and wavelength.
If
is the speed of electromagnetic radiation,
is its frequency, and
is its wavelength, then:

Therefore, wavelength is inversely proportional to its frequency.
Hence, as wavelength increases, the frequency decreases.
The LAST choice is the correct one.
