I believe the answer is Mouse/Herbivore. It was a question in my old lab haha.
Hope this helped!!

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). ![v_p - v_w = \dfrac{900km}{120min}](https://tex.z-dn.net/?f=v_p%20-%20v_w%20%3D%20%5Cdfrac%7B900km%7D%7B120min%7D)
And when the plane is flying with the wind, it covers the same distance in 1 hour 48 minutes (108 minutes)
(2). ![v_p+v_w= \dfrac{900km}{108min}](https://tex.z-dn.net/?f=v_p%2Bv_w%3D%20%5Cdfrac%7B900km%7D%7B108min%7D)
From equation (1) we solve for
and get:
,
and by putting this into equation (2) we get:
![\dfrac{900km}{120min}+v_w+v_w= \dfrac{900km}{108min}](https://tex.z-dn.net/?f=%5Cdfrac%7B900km%7D%7B120min%7D%2Bv_w%2Bv_w%3D%20%5Cdfrac%7B900km%7D%7B108min%7D)
![2v_w= \dfrac{900km}{108min}-\dfrac{900km}{120min}](https://tex.z-dn.net/?f=2v_w%3D%20%5Cdfrac%7B900km%7D%7B108min%7D-%5Cdfrac%7B900km%7D%7B120min%7D)
![2v_w = 8.3km/min - 7.5km/min](https://tex.z-dn.net/?f=2v_w%20%3D%208.3km%2Fmin%20-%207.5km%2Fmin)
![2v_w = 0.83km/min](https://tex.z-dn.net/?f=2v_w%20%3D%200.83km%2Fmin)
![v_w = 0.4165km/min](https://tex.z-dn.net/?f=v_w%20%3D%200.4165km%2Fmin)
or in km/hr this is
![\boxed{v_w= 25km/hr }](https://tex.z-dn.net/?f=%5Cboxed%7Bv_w%3D%2025km%2Fhr%20%7D)
Answer:
Weight is a force
Explanation:
Weight is the force of gravity on a mass. It can also be seen through this equation: F=ma, where m is the mass of the object and a is the acceleration of gravity.
