Answer:

mixture

Explanation:

All matter is made of particles; these can be single atoms or atoms chemically joined to make molecules. Using this fact, matter can be classified into three broad groups: elements, compounds and mixtures. In an element, all the atoms are of the same type. If more than one type of atom is chemically joined, then a compound has been formed. If more than one type of atom or molecule is contained in the same substance, and the particles aren't chemically joined, this is a mixture.

Find the energy released in the fission reaction¹₀n + ²³⁵₉₂U → ⁹⁸₄₀Zr + ¹³⁵₅₂Te +3(¹₀n) The atomic masses of the fission product
ikadub [295]

Fission reaction is given

¹₀n + ²³⁵₉₂U → ⁹⁸₄₀Zr + ¹³⁵₅₂Te +3(¹₀n)

The atomic masses of the fission products are 97.912735 u for ⁹⁸₄₀Zr and 134.916450 u for ¹³⁵₅₂Te. Hence, the energy released in fission reaction is 191.715 MeV.

How to find the energy released in the given fission reaction?

We know, that the atomic mass of the elements are as follows:

  • ⁹⁸₄₀Zr - 97.9120u
  • ¹³⁵₅₂Te - 134.9087u
  • ²³⁵₉₂U  - 235.0483923u
  • n = 1.008665u

In order to find the mass difference, we will calculate the initial mass and the mass of products.

The equation for the reaction:

n + ²³⁵₉₂U → ⁹⁸₄₀Zr + ¹³⁵₅₂Te +3n

Mass of initial reagents is 1.008665u + 235.0483923u = 233.052588u

Product of the reagents is 97.9120u + 134.9087u + 3(1.008665u) = 235.846773u

Now, using the formula of

E=(\triangledown m)c^2

E=(0.205815u)\frac{931.494MeV/c^2}{u} c^2=191.715MeV

Hence, the energy released in fission reaction is 191.715 MeV.

A child rolls a ball on a level floor 4.0 m to another child. if the ball makes 10.0 revolutions, what is its diameter?
olga_2 [115]
Circumference : 4/10=0.4m 
Since diameter = circumference / pi (3.14) 
d = 0.4/pi = 0.127388m  
So your answer is 0.127388m

A tank is 10 m long, 8 m wide, 4 m high, and contains kerosene with density 820 kg/m3 to a depth of 3.5 m. (Use 9.8 m/s2 for the
Alexxandr [17]

Answer:

28,126pascal

Explanation:

Hydrostatic pressure exerted on the bottom of the tank can be calculated using the formula

P = hpg where;

h is the depth of the tank = 3.5m

p is the density of the kerosene = 820kg/m³

g is the acceleration due to gravity = 9.8m/s²

Substituting the values into the formula we have;

P = 3.5×820×9.8

P = 28,126Pascal

Reena has rolled down her toy car through a ramp. When she increases the height of the ramp (10 cm ) the car has travelled 5 met
Stolb23 [73]

Answer:

As she raises the height of the ramp, the speed of the toy car decreases.

Explanation:

Speed is the ratio of the distance traveled by an object to the time taken.

i.e speed = \frac{distance}{time}

From the given question, it would be observed that:

i. when the height of the ramp was 10 cm, the car traveled 5 meters.

ii. when the height of the ramp was increased to 13 cm, the car traveled 6 meters.

Therefore, an increase in the height of the ramp causes a decrease in the speed of the toy car so that the distance traveled per unit time increases. Showing that there is an inverse relationship between the height of the ramp and the speed of the toy car.
