A = 94
B = 36
C = Kr or Krypton
Explanation:
The given nuclear reaction is written below:
²³⁵₉₂ U + ₀¹ n ⇒ ¹³⁹₅₆Ba + ᵃₙ C + 3¹₀n
Although mass and matter is not conserved in nuclear equations, the mass and atomic number must be conserved.
This implies that the mass number on both side of the equation be the same. The atomic number too must be the same.
Conserving mass number;
235 + 1 = 139 + a + 3(1)
a = 236 - 142 = 94
Conserving atomic number:
92 + 0 = 56 + n + 3(0)
92 = 56 + n
n = 36
A = 94
B = 36
C = Kr or Krypton

Heat is technically the movement or more like vibration of the molecules. More thermal energy = more vibration
The SI system was created so most countries can have the same units and cause no confusion.
Answer:
The spring constant = 104.82 N/m
The angular velocity of the bar when θ = 32° is 1.70 rad/s
Explanation:
From the diagram attached below; we use the conservation of energy to determine the spring constant by using to formula:
Also;
Thus;
where;
= deflection in the spring
k = spring constant
b = remaining length in the rod
m = mass of the slender bar
g = acceleration due to gravity
Thus; the spring constant = 104.82 N/m
b
The angular velocity can be calculated by also using the conservation of energy;
Thus, the angular velocity of the bar when θ = 32° is 1.70 rad/s
