Yea it’s called the Saffir-Simpson Hurricane scale, made in 1960s and further developed in 1970s
Answer:
lacceleration is given by
a=F/m
With force acting on the object remained constant ,the acceleration is inversly proportional to mass of the object i.e with increase in mass =>acceleration decreases and with decrease in mass => acceleration increases.
a)
acceleration decreases
b)
acceleration increase
Answer:
The answer to the question is;
Based on their acceleration the rank of the satellites from largest to smallest is.
B >→ A >→ E >→ C >→ F >→ D.
Explanation:
Acceleration is given by 
Therefore the acceleration for each of the satellite is given by
Satellite A)
= 5.12 m/s²
Satellite B)
= 10.24 m/s²
Satellite C)
= 2.56 m/s²
Satellite D)
= 0.16 m/s²
Satellite E)
= 2.88 m/s²
Satellite F)
= 0.64 m/s²
Therefore in order of decreasing acceleration, from largest to smallest we have
Satellite B) > Satellite A) >Satellite E) >Satellite C)>Satellite F)>Satellite D).
Answer:
1.40 N
Explanation:
The magnitude of the frictional force is given by:

where
is the coefficient of friction
N is the magnitude of the normal reaction
The coefficient of friction for this problem is
. The magnitude of the normal reaction is equal to the combined weight of the boy and the sled, because the surface is horizontal, so

Therefore, the frictional force is
