you must write the temprature of the copper sulfate solution on the on the y axis
Here it is given that initial speed of the package will be same as speed of the helicopter
![v_i = 5.10 m/s](https://tex.z-dn.net/?f=v_i%20%3D%205.10%20m%2Fs)
displacement of the package as it is dropped on ground
![d = -105 m](https://tex.z-dn.net/?f=d%20%3D%20-105%20m)
acceleration is due to gravity
![a = -9.8 m/s^2](https://tex.z-dn.net/?f=a%20%3D%20-9.8%20m%2Fs%5E2)
now by kinematics
![y = v* t + \frac{1}{2}at^2](https://tex.z-dn.net/?f=y%20%3D%20v%2A%20t%20%2B%20%5Cfrac%7B1%7D%7B2%7Dat%5E2)
![-105 = 5.1 * t - \frac{1}{2}*9.8*t^2](https://tex.z-dn.net/?f=-105%20%3D%205.1%20%2A%20t%20-%20%5Cfrac%7B1%7D%7B2%7D%2A9.8%2At%5E2)
![4.9 t^2 - 5.1 t - 105 = 0](https://tex.z-dn.net/?f=4.9%20t%5E2%20-%205.1%20t%20-%20105%20%3D%200)
by solving above equation we have
![t = 5.2 s](https://tex.z-dn.net/?f=%20t%20%3D%205.2%20s)
so it will take 5.2 s to reach the ground

<span>Technician a says that to prevent injuries in an auto accident, all steering columns have a break-off steering wheel. technician b says that to prevent injuries in an accident, all steering columns are now fitted with a flexible rubber tube. Both technicians are correct. The </span>vehicle manufacturers use break away steering column mounting brackets to protect the driver in an accident. The <span>vehicle manufacturers are required to use collapsible shafts in the steering column. </span>
Hello,
The answer is B) <span>electrical to mechanical.
</span><span>
When a hair dryer is being used, one of the energy transformations that takes place is </span>electrical to mechanical. Once you plug the hair dryer into the outlet, an electric current flows, starting the mechanical hair dryer.
