Total number of invoices = 30,800
Invoices produced by each computer = 30,800/2 = 15,400
Rates:
Computer 1 = 7,700/hr
Computer 2 = 6,800/hr
Time taken by computer 1 = 15,400/7,700 = 2 hrs
In 2 hrs, invoices produced by computer 2 = 2*6,800 = 13,600
Invoices remaining after the two hours when computer 1 finishes = 15,400 - 13,600 = 1,800 invoices.
When you play a piano, your energy increases in a uniform, continuous manner and is therefore quantized.When you play a piano, you can press only on individual keys, so that your energy is restricted to certain values and is therefore quantized.
The answers that apply;
- may involve a change in total mass
- involve very high-energy changes
- involve changes in nuclides when decay occurs
There are two types of radioactive reactions; fission and fusion. Fission involves the splitting of an unstable isotope (with a high mass number) into stable elements (of lower mass number) that differ in characteristics from the parent atoms. Fusion involves the fusion of two light atoms into a heavier atom. Both reactions emit huge quantities of energy in the process.
Answer:
Chromosphere
Explanation:
The Chromosphere is one of the important internal layers of the sun, which lies above the layer of Photosphere. The Chromosphere has a thickness of about 3 to 5 km having a very high temperature, ranging from about 5000 to 20,000°C. Due to this extreme temperature and continuous nuclear fusion process that takes place at the core of the sun, there forms the reddish colored layer, which is usually not visible but can be observed during the time of a total solar eclipse, by the use of an ultraviolet telescope.
Answer:
0.1 m/s
Explanation:
Please see attached photo for explanation.
Mass of 1st cart (m₁) = 500 g
Initial velocity of 1st cart (u₁) = 0.25 m/s
Mass of 2nd cart (m₂) = 750 g
Initial velocity of 2nd cart (u₂) = 0 m/s
Velocity (v) after collision =.?
m₁u₁ + m₂u₂ = v(m₁ + m₂)
(500 × 0.25) + (750 × 0) = v(500 + 750)
125 + 0 = v(1250)
125 = 1250v
Divide both side by 1250
v = 125 / 1250
v = 0.1 m/s
Thus, the two cart will move with a velocity of 0.1 m/s after collision.
