Answer:
1000 cm.
Explanation:
To obtain the estimated tree height :
(Height of rod / length of rod shadow) = (height of tree / length of tree shadow)
Substituting values into the formula :
(150cm / 120 cm) = (height of tree / 800 cm)
Using cross multiplication :
Height of tree * 120 = 150 * 800
Height of tree = (150 * 800) / 120
Height of tree = 120,000 / 120
Height of tree = 1000
Hence, estimate height of tree = 1000 cm
Answer:
196
Explanation:
subtract 24 from 220 to get your answer.
1. distance plus direction
displacement
2. 30 m/s northwest, for example
velocity
3. total distance divided by total time
average speed
4. what an object going around a curve at a constant speed is
undergoing
acceleration
5. 30 m/s, for example
speed
6. any non-directional quantity
scalar
That's law of conservation of mass..
the original log changes its form of mass that ash but the total mass of the system remains constant that's the law of conservation of mass
