Answer:
The speed of the wind is 25 km/hr.
Explanation:
Let us call the speed of the plane and
the speed of the wind. When the plane is flying against the wind, it covers the distance of 900-km in 2 hours (120 minutes); therefore;
(1).
And when the plane is flying with the wind, it covers the same distance in 1 hour 48 minutes (108 minutes)
(2).
From equation (1) we solve for and get:
,
and by putting this into equation (2) we get:
or in km/hr this is
<u>Answer:</u>
2N/cm
<u>Step-by-step explanation:</u>
According to the Hooke's Law, the force required to extend or compress a spring is directly proportional distance you can stretch it, which is represented as:
where, is the force which is stretching or compressing the spring,
is the spring constant; and
is the distance the spring is stretched.
Substituting the given values to find the elastic constant to get:
Therefore, the elastic constant is 2 Newton/cm.
