The number of neutrons is equal to the atomic mass, or mass number, minus the atomic number:
80 - 33 = 47 neutrons.
Answer:
the creation of oxygen
Explanation: i just took the k12 test :)
The average force on the shell while it is in the gun barrel is 10,869,833.33N.
<h3>HOW TO CALCULATE FORCE?</h3>
Force applied on an object can be calculated by multiplying the mass of the object by its acceleration.
However, the acceleration needs to be calculated by using the following equation:
v² - u² = 2as
Where;
- v = final velocity
- u = initial velocity
- a = acceleration
- s = distance
770² - 0² = 2 (a)(1.5)
592900 = 3a
a = 197633.3m/s²
Force = 55kg × 197633.3m/s²
Force = 10,869,833.33N
Therefore, the average force on the shell while it is in the gun barrel is 10,869,833.33N.

Answer:
0.5
Explanation:
From the question given above, the following data were obtained:
Force (F) = 50 N
Weight (W) = 100 N
Coefficient of static friction (μ) =.?
The coefficients of static friction (μ) is simply defined as the ratio of force (F) to the normal reaction (N). Mathematically, it can be expressed as:
μ = F / N
With the above formula, we can obtain the coefficient of static friction as follow:
Force (F) = 50 N
Weight (W) = 100 N
Coefficient of static friction (μ) =.?
μ = F / W
μ = 50 / 100
μ = 0.5
Thus, coefficient of static friction is 0.5
Sculpture is the correct answer
