Answer:
0.0059
Explanation:
According to the question the seismic activity density is given by
Here,
Number of Earthquakes over a given time span = 424
The land area affected = 71300 mi²
So,
The seismic activity density is 0.0059

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
