The altitude is usually low. Tropical places are mainly on the ocean, that's usually why it's so hot. They are usually close to the equator, but not right on it. The tropics get a lot of direct sunlight, so wear that sunscreen! The ocean currents are warm, so they bring along warm water. All of those help make the tropics the way they are.

Answer:
The force needed will be 5000[N]
Explanation:
Using the Newton's second law we have:
![F = m*a\\where\\F = force [N]\\m = mass [kg]\\a= acceleration [m/s^2]\\Replacing we have\\F = 0.025[kg]*200000[m/s^2]\\F = 5000 [N]](https://tex.z-dn.net/?f=F%20%3D%20m%2Aa%5C%5Cwhere%5C%5CF%20%3D%20force%20%5BN%5D%5C%5Cm%20%3D%20mass%20%5Bkg%5D%5C%5Ca%3D%20acceleration%20%5Bm%2Fs%5E2%5D%5C%5CReplacing%20we%20have%5C%5CF%20%3D%200.025%5Bkg%5D%2A200000%5Bm%2Fs%5E2%5D%5C%5CF%20%3D%205000%20%5BN%5D)
Answer:
The primary reason of seeing the cracker burst and hearing the sound later is because the speed of sound and light. Speed of light is in the vicinity of 3*10^8m,/ sec while the speed of sound is at a distance of 332m/sec. It is similar to lightning that strikes before the sound.
