Beat frequency, fb = |f2-f1|
That is, beat frequency is the absolute difference between two frequencies. Is is as a results of destructive and constructive inferences.
Therefore, in this case:
fb = 203 - 199 = 4 Hz
Gravity is the energy due to Earth pulling down on an object.
Answer:
(I) meteorite is usually covered with a dark crust from burning in Earth's atmosphere.
(II) A meteorite usually has a high metal content.
(III) Meteorites when compared to terrestrial rocks have different isotope ratios of particular elements.
(IV) Meteorites contain rare elements, such as iridium, that terrestrial rocks do not contain.
Answer:
a' =4.15 m/s²
Explanation:
Given that
m= 3.2 kg
F₁ = 1.9 i −1.9 j N
F₂=3.8 i −10.1 j N
From second law of Newton's
F(net) = m a
F₁ + F₂ = m x a
1.9 i −1.9 j + 3.8 i −10.1 j = 3.2 a
a = 1.78 i - 3.75 j m/s²
The resultant acceleration a'
a' =4.15 m/s²
