Answer:
Option B. 4
Explanation:
From the question given above, the following data were obtained:
Input force = 2.5 N
Output force = 10 N
Mechanical advantage (MA) =?
Mechanical advantage (MA) is simply defined as the ratio of the output force to the input force. Mathematically, it can be expressed as:
Mechanical advantage = Output : Input
MA = Output / Input
With the above formula, we can obtain the mechanical advantage of the pulley system as follow:
Input force = 2.5 N
Output force = 10 N
Mechanical advantage (MA) =?
MA = Output / Input
MA = 10/2.5
MA = 4
Thus, the mechanical advantage of the pulley system is 4.
Answer:
towards the center of the circle
(which appears to be the last option in your list of possible answers)
Explanation:
The centripetal force points always towards the center of the circle described by the object moving.
Answer:
Explanation:
I think there are some repetitions in the question which may be due to typographical errors. The correct question should have been as stated below:
An airplane flies eastward and always accelerates at a constant rate. At one position along its path, it has a velocity of 32.3 m/s . It then flies a further distance of 41300 m, and afterwards, its velocity is 43.1 m/s . Find the airplane's acceleration.
This problem could be solved using the third equation of a uniformly accelerated motion, since the airplane is said to accelerate at a constant (uniform) rate. The equation is given by;
where v is the final velocity, u the initial velocity, a acceleration and s distance.
We substitute these values into the equation and then solve for the unknown;

D) 8000 N
F = Mass × Acceleration
