aerosol can carry warnings on their labels that say not to incinerate (burn ) them or store the cans above a certain temperature

. the gas in a used aerosol can is at a pressure of 103 KPA at 25 °c. if the can is thrown into a fire, what will the pressure be when the temperature reaches 928°c?​

Answer:

The volume is the same apply this formula Pv=nRT shows direct proportionality this is what shows so we can take only PV=T and v stays the same.

The quantum state of a particle can be specified by giving a complete set of quantum numbers (n,l, ml, ms). How many different q
Delvig [45]

Answer:

number of quantum states =  8

Explanation:

To find the total number of allowed states you take into account the following relations:

l=n-1\\\\m_l=-l,-(l-1),...,0,,,,(l-1),l

in this case you have:

n=2\\\\l=0,1\\\\m_0=0\\\\m_1=-1,0,1

furthermore, for each n,l,ml quantum state you have two additional states due to the spin of the electrons.

then, you have (n,l,ml) = (2,0,0), (2,1,-1), (2,1,0), (2,1,1) and with the spin:

number of quantum states = 2*(1+3) = 8

A ball is tied to a 1.3 m string and whirled in a circular motion with a force of 220 N. If its speed is 6 m/s, (a) what is it c
Studentka2010 [4]

The centripetal acceleration is 27.692 kg m / s^2.

The mass of the ball is 7.94 kg.

<u>Explanation:</u>

  • The curved path of an object experience a force known as centripetal force. Its direction is always pointing to the motion of the body towards the center of curvature of the path.

            centripetal force Fc = (mass * square of velocity) / radius

where m represents mass in kg

          v represents  velocity

          r represents radius in a meter.

  • The acceleration experienced in uniform circular motion is called as centripetal acceleration.It always points toward the center of rotation and is perpendicular to the linear velocity.
  •                     centripetal acceleration = v^2 / r

                                                             = (6 * 6) / 1.3

                                                             = 27.692 kg m / s^2.

 The mass of the ball is found by using the centripetal force formula,

  •                               centripetal force Fc = m v^2 / r

                                                      m = (F * r) / v^2

                                                          =  (220 * 1.3) / 36

                           mass of the ball  m = 7.94 kg.
