For this case we must convert 26 seconds to hours,
By definition we have to:
1 hour equals 3600 seconds.
So, if we propose a rule of three we have:
1 hour ----------> 3600 seconds
x ------------------> 26 seconds
Where the variable "x" represents the number of hours equivalent to 26 seconds:
Thus, 26 seconds equals approximately 0.0072 hours.
Answer:
0.0072 hours
Answer:
E = -8.23 10⁻¹⁷ N / C
Explanation:
In the Bohr model, the electric potential for the ground state corresponding to the Bohr orbit is
E = k q₁ q₂ / r²
in this case
q₁ is the charge of the proton and q₂ the charge of the electron
E = - k e² / a₀²
let's calculate
E = - 9 10⁹ (1.6 10⁻¹⁹)² / (0.529 10⁻¹⁰)²
E = -8.23 10⁻¹⁷ N / C
Answer:
Explanation:
First, we have to calculate the maximum height reached by the object. We use the equations of uniformly accelerated motion:
In order to calculate this, we have to know the time taken by the object to reach the maximum height:
Now, we can calculate y:
Now, we calculate the time taken by the object in free fall:
Finally, adding and , we get the total time until the object impacts the ground:
