The following equation is an example of decay?<br><br> 232/90 TH---4/2 HE +228/88 RA?
DaniilM [7]

Answer:

Alpha decay

Explanation:

  • Alpha decay is one of the three major types of decays, others being, beta decay and gamma decay.
  • <em><u>When a radioactive isotope undergoes alpha decay it emits alpha particles. An alpha particle is equivalent to the nucleus of Helium atom.</u></em>
  • <em><u>Therefore, an atom undergoing decay, its atomic mass is decreased by 4 and its atomic number is decreased by 2. </u></em>
  • Thus, since 232/90 Th, has undergone alpha decay its mass number is reduced by 4 to 228 and its atomic number by 2 to 88, and becomes 228/88 Ra.

Why is respiration an exothermic reaction? A. a large amount of energy is released into its surroundings B. the heat content, q,
Rina8888 [55]
A. a large amount of energy released into its surrounding

During the respiration, glucose molecules are converted to other molecules in a series of steps. They finally end up as as carbon-dioxide and water.

The overall reaction is

<span>C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + 2805 kJ
</span>
The reaction is exothermic reaction because <span>C=O and O-H bonds in the products are so much more stable than the bonds in the reactants.
</span>
Bond energy is the average needed to break a bond.

Some bond energies are:
C-C = 347 kJ/mol
C-H = 413kJ/mol;
C-O = 358 kJ/mol;
O-H = 467 kJ/mol;
O=O = 495 kJ/mol;
<span>C=O = 799 kJ/mol</span>

The reason why the position of an electron cannot be measured with absolute precision is:
LenKa [72]
They are too small are never in the same place. Electrons are constantly moving in random motion within the electron cloud, making them impossible to follow.

Discuss the relationship between electric and magnetic fields. How are they related?
evablogger [386]
<span>Discuss the relationship between electric and magnetic fields. How are they related?</span>

The magnetic field is related to the electric field in such a way that magnetic fields moves perpendicular the electric field. This relationship exists between a magnetic field and an electric field is a consequence of associating elementary particles.

At an amusement park, a Physics 114 takes a ride on a fast-moving Ferris wheel. The apparent weight of the student is different
Rudiy27

Answer:

N1 / N2 = 1.0016

Explanation:

The apparent weight of the student is the value that a balance would have this corresponds in this case to the normal of the student. Let's write Newton's second law in the lower and upper part of the loop

For lower rotating wheel

    N1 - W = m a

    a = v² / r

    N1 = W + v² / r

The relationship between linear and angular velocity is

    v = w r

As the wheel rotates at a constant speed, we can use angular kinematics

    w = θ / t

    θ = 3 rev (2π rad / 1rev) = 6π rad

    w = 6π / 150

    w = 0.04π rad / s = 0.1257 rad / sec

calculate    

   N1 = mg + w² r

   N1 = 55 9.8 + 0.1257² 27

   N1 = 539 + 0.4267

   N1 = 539.426 N

Now we perform the same calculation for the top

   -N2 - W = -m a

    N2 = -W + ma

    N2 = 539 - 0.4267

    N2 = 538.5733 N

The relationship between the weight at the bottom and top is

   N1 / N2 = 539.4267 / 538.5733

   N1 / N2 = 1.0016
