Answer:
22m/s
Explanation:
Given parameters:
Time = 5s
Acceleration = 4m/s²
Initial velocity = 2m/s
Unknown
Final speed = ?
Solution:
To solve this problem, we use the expression below;
v = u + at
v is the final speed
u is the initial speed
a is the acceleration
t is the time taken
So, insert the parameters and solve;
v = 2 + 4 x 5 = 22m/s
Answer:
Evaporation happens when a liquid substance becomes a gas. When water is heated, it evaporates. The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor.
