Answer:
New acceleration is 20.0 m/s².
Explanation:
F = m*a
F = 0.35 kg * 10.0m/s²
If Force will be doubled , and mass will be the same
we can write
2F = 2*0.35 kg*10.0 m/s²=0.35kg*20.0m/s²
New acceleration is 20.0 m/s².
1. the amount of electric charge that they carried
2. the distance between them
A baseball would hit the bat harder. This is because the baseball is a lot heavier and more dense than the plastic ball. The keyword that you're looking for is density. The baseball is dense.
Answer:

Answer:
14.32 Hz
Explanation:
Given:
Frequency of the horn, f₀ = 395 Hz
Speed of the car, v = 12.0 m/s
Speed of the sound, c = 343 m/s
now, applying the doppler's effect formula, we have
where,
f is the observed frequency
on substituting the values, we get
or
f = 409.32 Hz
therefore,
the beat frequency heard is = f - f₀ = 409.32 - 395 = 14.32 Hz
