Answer:
a) 24.918 m
b) 4.5078 seconds
c) [0.18, 0.39]
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration due to gravity = 9.81 m/s²
At the beginning of the last 1 second the velocity will be 15.095 m/s
Taking that as the final velocity of the path from the maximum height we find time
So, the ball traveled for 1+1.539 = 2.2539 seconds from the maximum height to the ground.
The maximum height the ball traveled is 24.918 m.
The time the ball will take to go up is 2.2539 seconds
So, total time the ball will be in flight is 2.2539+2.2539 = 4.5078 seconds
Solving the above equation we get
t = 0.18 seconds
Solving the equation we get
t = 0.39 seconds
So, the ball will traveling in the [0.18, 0.39] seconds of the flight
Answer;
-Single replacement
Explanation;
The reaction;
Cu(s) + 2AgNO3= Cu(NO3)2 + 2Ag , is an example of a single replacement reaction.
-It is a type of chemical reaction where an element reacts with a compound and takes the place of another element in that compound.
In the above reaction copper(Cu) takes the place of silver(Ag) in the salt AgNO3 to form Copper (ii) nitrate (CuNO3) and silver metal (Ag).
- Another example of a single replacement reaction occurs when potassium (K) reacts with water (H2O). A colorless solid compound named potassium hydroxide (KOH) forms, and hydrogen gas (H2) is set free.
The 3 parts of the lever is:
1. Fulcrum lever. The fulcrum lever is the support point on which a lever pivots.
2. Load lever. A load lever is the object that is being moved by a lever.
3. Effort lever. Last but not least, the effort lever is the force that is needed to move an object
