Answer:
Kinetic - a box moving
Thermal - sand that feels warm
Electrical - lightning
Radiant - radio waves
Gravitational Potential - fruit hanging from a tree

Cheetah speed: ![v_c = 97.8 km/h=27.2 m/s](https://tex.z-dn.net/?f=v_c%20%3D%2097.8%20km%2Fh%3D27.2%20m%2Fs)
Its position at time t is given by
(1)
Gazelle speed: ![v_g = 78.2 km/h=21.7 m/s](https://tex.z-dn.net/?f=v_g%20%3D%2078.2%20km%2Fh%3D21.7%20m%2Fs)
the gazelle starts S0=96.8 m ahead, therefore its position at time t is given by
(2)
The cheetah reaches the gazelle when
. Therefore, equalizing (1) and (2) and solving for t, we find the time the cheetah needs to catch the gazelle:
![v_c t=S_0 + v_g t](https://tex.z-dn.net/?f=v_c%20t%3DS_0%20%2B%20v_g%20t)
![(v_c -v_g t)=S_0](https://tex.z-dn.net/?f=%28v_c%20-v_g%20t%29%3DS_0)
![t=\frac{S_0}{v_c-v_t}=\frac{96.8 m}{27.2 m/s-21.7 m/s}=17.6 s](https://tex.z-dn.net/?f=t%3D%5Cfrac%7BS_0%7D%7Bv_c-v_t%7D%3D%5Cfrac%7B96.8%20m%7D%7B27.2%20m%2Fs-21.7%20m%2Fs%7D%3D17.6%20s)
(2) To solve the problem, we have to calculate the distance that the two animals can cover in t=7.5 s.
Cheetah: ![S_c = v_c t =(27.2 m/s)(7.5 s)=204 m](https://tex.z-dn.net/?f=S_c%20%3D%20v_c%20t%20%3D%2827.2%20m%2Fs%29%287.5%20s%29%3D204%20m)
Gazelle: ![S_g = v_g t =(21.7 m/s)(7.5 s)=162.8 m](https://tex.z-dn.net/?f=S_g%20%3D%20v_g%20t%20%3D%2821.7%20m%2Fs%29%287.5%20s%29%3D162.8%20m)
So, the gazelle should be ahead of the cheetah of at least
![d=S_c -S_g =204 m-162.8 m=41.2 m](https://tex.z-dn.net/?f=d%3DS_c%20-S_g%20%3D204%20m-162.8%20m%3D41.2%20m)
Answer: Physical
Explanation: There are no changes being done to the salt. Think of it this way, if you dissolve the salt in water then boil the water completely, you will have the same salt you started with.
Answer:
Because you have a greater understanding of the mentality and conduct of individuals you care about, you are better able to understand their perspective and are more likely to recognize possible situational factors for their behavior.
