<h2>
Answer: The volume will triple (increase by a factor of three).</h2>
Explanation:
The expression for an Ideal Gas is:
(1)
Where:
is the pressure of the gas
is the volume of the gas
the number of moles of gas
is the gas constant
is the absolute temperature of the gas
Finding :
(2)
If we are told the the amount of gas and pressure remain constant, but we increase the temperature by a factor of three; we will have to rewrite (2) with the new temperature :
(3)
(4)
Now, if we compare (2) with (4), it is clearly noticeable the volume of the gas has increased by a factor of 3.
Answer:
f = 3.97 Hz
Explanation:
Given that,
Centripetal acceleration,
The radius of motion is 0.02 m
The formula for the centripetal acceleration is given by :
The speed of an object in a circular path is given by :
t is time period
Also, f=1/t (f is frequency)
Hence, the frequency of motion s 3.97 Hz.
Answer:
Explanation:
The acceleration of an object is given by
where
v is the final velocity
u is the initial velocity
t is the time interval it takes for the velocity to change from u to v
For the car in this problem,
u = 21.0 m/s
v = 46.0 m/s
t = 2.5 s
Substituting, we find the acceleration
Answer:
The magnetic moment of a system measures the strength and the direction of its magnetism. The term itself usually refers to the magnetic dipole moment. Anything that is magnetic, like a bar magnet or a loop of electric current, has a magnetic moment. A magnetic moment is a vector quantity, with a magnitude and a direction. An electron has an electron magnetic dipole moment, generated by the electron's intrinsic spin property, making it an electric charge in motion. There are many different magnetic behavior including paramagnetism, diamagnetism, and ferromagnetism.
An interesting characteristic of transition metals is their ability to form magnets. Metal complexes that have unpaired electrons are magnetic. Since the last electrons reside in the d orbitals, this magnetism must be due to having unpaired d electrons. The spin of a single electron is denoted by the quantum number \(m_s\) as +(1/2) or –(1/2). This spin is negated when the electron is paired with another, but creates a weak magnetic field when the electron is unpaired. More unpaired electrons increase the paramagnetic effects. The electron configuration of a transition metal (d-block) changes in a coordination compound; this is due to the repulsive forces between electrons in the ligands and electrons in the compound. Depending on the strength of the ligand, the compound may be paramagnetic or diamagnetic.Explanation:
