Pure water. Lemon juice is acidic so it’s not neutral PH it has lower pH Hand soap is basic which makes it have more PH. baking soda is also a basic so it makes it higher ph.
1) find speed (8.8 m/s)
2) find acceleration (38.7 m/s^2)
answer is about 38.7 m/s^2
Answer:
Part 1. 4. 56 mi/h; Part 2. 7. 16 mi/h south; Part 3. 6. 56 mi/h north
Explanation:
Part 1. Average speed
Speed = distance/time
Distance = Austin-Waco + Waco-Austin + Austin-San Antonio
= 100 mi + 100 mi + 80 mi = 280 mi
Time = 5 h
Speed = 280 mi/5 h = 56 mi/h
Part 2. Average velocity
Velocity is a vector. It includes both speed and direction.
Assume south is positive and north is negative.
Distance = -100 mi + 100 mi + 80 mi = +80 mi
Velocity = +80 mi/5h = +16 mi/h = 16 mi/h south
Part 3. Average velocity Austin-Waco
Distance = north
If the student kept to an average speed of 56 mi/h, the average velocity was 56 mi/h north.
Answer:
3.528×10⁻⁸ V.
Explanation:
Electric Potential: This can be defined as the work done in an electric field in moving a unit charge from infinity to any point. The S.I unit of electric potential is Volt (V) or J/C.
From the question,
V = Fd................ Equation 1
Where V = Electric Potential, F = force experienced by the charge, d = distance.
Given: F = 3.6×10⁻⁴ N, d = 9.8×10⁻⁵ m.
Substitute into equation 1
V = 3.6×10⁻⁴( 9.8×10⁻⁵)
V = 3.528×10⁻⁸ V.
