Answer:
6080 N
Explanation:
From the question given above, the following data were obtained:
Mass (m) of car = 800 Kg
Acceleration (a) of car = 7.6 m/s²
Force (F) =?
The force experienced by the car can be obtained as illustrated below:
Force (F) = mass (m) × acceleration (a)
F = m × a
F = 800 × 7.6
F = 6080 N
Thus, the experience a force of 6080 N
Answer:
it means you have 4 sodium
Explanation:
Answer:
[H⁺] = 5.012 x 10⁻⁹. & [OH⁻] = 1.995 x 10⁻⁶.
Explanation:
∵ pH = - log[H⁺]
8.3 = - log[H⁺]
∴ log[H⁺] = - 8.3.
<em>∴ [H⁺] = 5.012 x 10⁻⁹.</em>
∵ [H⁺][OH⁻] = 10⁻¹⁴.
<em>∴ [OH⁻] = 10⁻¹⁴/[H⁺] </em>= 10⁻¹⁴/(5.012 x 10⁻⁹) = <em>1.995 x 10⁻⁶.</em>
