What would you predict is worse based on your knowledge of quantum theory - a weak beam of ultraviolet light, or an intense beam

of infrared light?

Answer : Amongst the given choices a weak beam of ultraviolet light is considered to be the worst as compared to others.

The wavelength of UV light is from 10 nm to 400 nm, and its energy varies from 3 eV to 124 eV.

As a single beam of UV light will have much energy in each photon which is emitted. The damage done by UV rays is observed to be very harmful in human cells and may cause many diseases. UV rays can also damage the eyes as more than 99% of UV radiation is absorbed by the front of the eyes. It can also lead to ultimate blindness. Therefore, it is considered to be much worse than an intense beam of infrared light.

Particle 1 has a velocity v1 = 2 m/s and a mass m1 = 2 kg . this particle collides with particle 2 of mass m2 = 6 kg , which is
creativ13 [48]
This follows the law of conservation of momentum. Momentum is the product of mass and velocity of object. 
Momentum = mass(m) x velocity(v) 
law of conservation of momentum means that the total momentum of system before the collision of 2 objects is equal to the total momentum after the collision 
Before the collision total momentum 
= m1v1 + m2v2
m1 = 2 kg
v1 = 2 m/s
m2 = 6 kg
v2 = 0 m/s
substituting the values in the equation 
total momentum before = (2 kg x 2 m/s) + (6 kg x 0 m/s)
total momentum = 4 kgm/s
after the collision the 2 objects stick together and have a common velocity 
total momentum after the collision  = (6 kg + 2 kg)x V  = 8V
V = speed of the conglomerate particle

since total momentum before is equal to total momentum after
8V = 4
V = 2 m/s
speed of conglomerate particle is 2 m/s

Calculate the mass percent for all components in a solution containing the following. 0.350 Kg of water, 5.4 moles of ammonia an
Alina [70]

Answer:

  • % Water = 54.96%
  • % Ammonia = 0.14%
  • % Cobalt (II) Nitrate = 30.62%

Explanation:

To calculate mass percent, first we need to <u>calculate the total mass of the mixture</u>:

  • Mass Water ⇒ 0.350 kg Water = 350 g water
  • Mass Ammonia⇒We use ammonia's molar mass⇒5.4 mol * 17 g/mol =  91.8 g
  • Mass cobalt (II) nitrate ⇒ 195.0 g

Total Mass = Mass Water + Mass Ammonia + Mass Cobalt Nitrate

  • Total Mass = 350 g+ 91.8 g+ 195 g = 636.8 g

To calculate each component's mass percent, we divide its mass by the total mass and multiply by 100:

  • % Water ⇒ 350/636.8 * 100% = 54.96%
  • % Ammonia ⇒ 91.8/636.8 * 100% = 0.14%
  • % Cobalt (II) Nitrate ⇒ 195/636.8 * 100% = 30.62%
