Answer:
Multiply the acceleration by time to obtain the velocity change:
Example:
Velocity change = 6.95 * 4 = 27.8 m/s . Since the initial velocity was zero, the final velocity is equal to the change of speed. You can convert units to km/h by multiplying the result by 3.6: 27.8 * 3.6 ≈ 100 km/h
Answer:
D
Explanation:
D it generates pressure by fusing hydrogen.
Answer:
343/440
Explanation:
Recall that v=d/t
Now, this is the same thing.
Frequency is 1/T and wavelength is the distance travelled in one period.
So Vs=f*λ
(the greek letter is used as the symbol of wavelength; it's arbitrary)
The student must have made an error in her measurement in the concentration of hydrogen ion in the basic solution given. From her measurement, the concentration is 1 × 10−3 M. If we calculate the pH, we get:
pH = -log ( 1 × 10−3) = 3
A pH of 3 does not signifies a basic solution it is in the acidic range. So, the measurement is wrong.
