Answer:
1.5 m/s²
Explanation:
Applying,
a = (v-u)/t ...................... Equation 1
Where a = acceleration of the particle, v = final velocity of the particle, u = Initial velocity of the particle, t = time.
From the question,
Given: u = 0 m/s (From rest), v = 15 m/s, t = 10 seconds
Substitute these values into equation 1
a = (15-0)/10
a = 15/10
a = 1.5 m/s²
Answer: 3
Explanation:
Lithium always has 3 protons bc it’s atomic number is 3 which is determined by its amount of protons.
I believe the correct answer from the choices listed above is the last option. The advances in food production that were attributed to the Green Revolution of the 1960s and 1970s are drought-resistant varieties of crop plants.
Hope this answers the question. Have a nice day.
Answer:
Since velocity is a vector quantity there is no net displacement and the average velocity is zero
(A) is correct
the musical instrument such as a piano may be tuned by using the phenomenon of beats.
The phenomena of beat frequency is often used to tune musical instruments like piano. A tuning fork is tapped ad a string of paino is plucked simultaneously. If the two sound sources produce beats whose frequencies are different, their frequencies won't be identical, and they are will out of tune and noise. Hence the above process is repeated until the frequencies are identical and resonant and the frequencies are not distinguished. Thus making the instrument in tune
This method will work more efficiently for an instrument that is entirely out of tune because it will be easier to distinguish the beats of the instruments and the tuning fork.
Hence the musical instrument such as a piano may be tuned by using the phenomenon of beats.
