Answer:
Market segmentation helps you send the right message, every time, by efficiently targeting specific groups of consumers.
Explanation:
Answer:
The coordinates of the target are (8790m, 3400m).
Explanation:
First of all, we have to find the components of the initial velocity
and
, using trigonometry:
![v_0_x=v_0\cos\theta=(360m/s)\cos50\°=231.4m/s\\\\v_0_y=v_0\sin\theta=(360m/s)\sin50\°=275.7m/s](https://tex.z-dn.net/?f=v_0_x%3Dv_0%5Ccos%5Ctheta%3D%28360m%2Fs%29%5Ccos50%5C%C2%B0%3D231.4m%2Fs%5C%5C%5C%5Cv_0_y%3Dv_0%5Csin%5Ctheta%3D%28360m%2Fs%29%5Csin50%5C%C2%B0%3D275.7m%2Fs)
Now, we find the x-coordinate using the equation of motion with constant speed (since there is no external force in x-axis that causes an horizontal acceleration):
![x=v_0_xt\\\\x=(231m/s)(38.0s)=8790m](https://tex.z-dn.net/?f=x%3Dv_0_xt%5C%5C%5C%5Cx%3D%28231m%2Fs%29%2838.0s%29%3D8790m)
Then, we find the y-coordinate using the equation of position of an object with constant acceleration (since there is the gravitational force causing a vertical acceleration on the shell):
![y=v_0_yt-\frac{1}{2}gt^{2}\\\\y=(276m/s)(38.0s)-\frac{1}{2}(9.81m/s^{2})(38.0s)^{2}=3400m](https://tex.z-dn.net/?f=y%3Dv_0_yt-%5Cfrac%7B1%7D%7B2%7Dgt%5E%7B2%7D%5C%5C%5C%5Cy%3D%28276m%2Fs%29%2838.0s%29-%5Cfrac%7B1%7D%7B2%7D%289.81m%2Fs%5E%7B2%7D%29%2838.0s%29%5E%7B2%7D%3D3400m)
Finally, the coordinates of the target are (8790m, 3400m).
Answer:
When boiling water is poured into a thick tumbler its inner surface expands. However, due to low thermal conductivity of glass, the expansion of outer surface of the tumbler is quite small. Due to uneven expansion of the outer and inner surfaces, the tumbler breaks.
