Answer: 0.42 km/min
Explanation:
total distance traveled(in meters) = 210m
total distance traveled(in km) = 210 ÷ 1000 = 0.21 km
total time taken(in seconds) = 30 s
total time taken(in minutes) = 30 ÷ 60 = 0.5 s
speed =(distance traveled)÷(time taken)[in km/min] = 0.21 ÷ 0.5 = 0.42km/min
An example would be 2 types of motion. It could be rectilinear or projectile motion. There are various equations for each type. Since you don't want me to tell you the answer, I could just express it in words. Then, it will be up to you to translate into mathematical equations.
For rectilinear motion, the distance traveled is equal to the initial velocity times the time, plus one-half of the acceleration times the square of the time. For projectile motion, the maximum distance is equal to the square of the initial velocity multiplied with the square of the sine of the launch angle, all over twice the gravity.
Answer: two way gravity is affected if somethings weight is doubled or grtavity gets weaker with distance
Explanation:
The component of Earth's atmosphere that is decreased due to photosynthesis is carbon dioxide (D).
