its about how the brain reacts
Answer:
Explanation:
The angular momentum of electron mvR = 6 x 10⁻²⁵ Js
Magnetic field B = 2.5 x 10⁻³ T
radius of circular path R = mv / Bq
where m is mass , v is velocity and q is charge on electron
R² = mvR / Bq
R² = 6 x 10⁻²⁵ / 2.5 x 10⁻³ x 1.6 x 10⁻¹⁹
= 1.5 x 10⁻³
R = 3.87 x 10⁻² m
mvR = 6 x 10⁻²⁵
v = 6 x 10⁻²⁵ / mR
= 6 x 10⁻²⁵ / 9.1 x 10⁻³¹ x 3.87 x 10⁻²
= .17 x 10⁸
= 17 x 10⁶ m/s
Answer:
The answer is C she didn't mark C so its your best best of trying.Good Luck!
Explanation:
Since the equation is not given in this case, you can follow this explanation to balance it up.
A balanced chemical equation is one in which the law of conservation of matter is strictly obeyed.
According to the laws, we know that the total mass of the reacting substances must be equal to that of the product.
To do this, coefficients are usually assigned to chemical species.
In order to know the right coefficient one can use;
- A trial by error method of inspecting and putting the appropriate coefficients in front of the formula of reactants or products.
- A mathematical method in which simple equations are derived can be used.
