Heya!
For this problem, use the formula:
s = Vo * t + (at^2) / 2
Since the initial velocity is zero, the formula simplifies like this:
s = (at^2) / 2
Clear a:
2s = at^2
(2s) / t^2 = a
a = (2s) / t^2
Data:
s = Distance = 518 m
t = Time = 7,48 s
a = Aceleration = ¿?
Replace according formula:
a = (2*518 m) / (7,48 s)^2
Resolving:
a = 1036 m / 55,95 s^2
a = 23,34 m/s^2
The aceleration must be <u>23,34 meters per second squared</u>
Explanation:
carbon dioxide, chlorophyll, water and light
Effective resistance = 2+1.5 = 3.5 ohms
Current in the circuit = 1.2 A
Lost volts in the battery = 1.8V
Current in one of the 3 ohms resistors = 0.6 A
I hope it helps
oof, that question is difficult! i would say its d because if you pull a slingshot farther than another one, it would have more potential energy.
Answer:
thermoset
Explanation:
A thermoset material is a polymer that is irreversibly hardened by curing. Curing is induced by heat and cannot be undone because the polymers cross link during the process, creating permanent chemical bonds.
