Time taken by each ion to travel the semicircular path through the magnetic field is 34 X 10⁻²⁶s.
<u>Explanation:</u>
Given:
Charge of oxygen ion, q = -2
Magnetic Field, B = 0.12 T
Mass of O₂ , m= 2.6 X 10⁻²⁶ Kg
Time, T = ?
We know,
Therefore,
T = 2 X 3.14 X 2.6 X 10⁻²⁶/ 2 X 0.12
T = 68 X 10⁻²⁶s
For semicircular orbit, Time taken would be T/2
T ₓ = 68 X 10⁻²⁶/2 s
T ₓ = 34 X 10⁻²⁶s
Therefore, time taken by each ion to travel the semicircular path through the magnetic field is 34 X 10⁻²⁶s.
Answer:
the nephew
Explanation:
because we need to First find the trails that is on top of all the others in order to find who was the last to leave, since the person that was last to leave would most likely step on another person's trail that has been theirs before them.
by looking at this picture I noticed that the butler's footprint was the latest one but the dogs footprint steps over it therefore making it the last to leave, and the person who owns a dog is her nephew so therefore the nephew is the one that stole the butterfly trophy.
"before cell phones, people who needed mobile communications ability installed radio telephones in their cars. in the radio telephone system, there was one central antenna tower per city, and perhaps 25 channels available on that tower. the cellular phone system divides the area of a city into small cells."
I hope this helps ^-^
Answer:
1.5g/cm³
Explanation:
Given parameters:
Initial volume of the liquid = 30cm³
Final volume of the liquid = 50cm³
Mass of the liquid = 30g
Unknown:
Density of the liquid = ?
Solution:
Density is the mass per unit volume of a substance.
Density = 
volume of the liquid = final volume - initial volume = 50cm³ - 30cm³
volume of the liquid = 20cm³
Density = 
= 1.5g/cm³
Answer:
His acceleration is 
Explanation:
Newton's second law states that acceleration of a body is cause by a net force, the relation between them is:
On the boy there're acting two forces, his weight (W) that points downward and the frictional force (f) that points upward (they boy moves downward and friction always is opposite to movement). So 
so (1) is:
Using the positive direction downward weight and gravitational acceleration(g) are positive and friction force is negative:
, solving for a:
, weight is mg:
