Answer:
13.4 m/s
Explanation:
Given:
Δx = 12 m
v₀ = 0 m/s
a = 7.5 m/s²
Find: v
v² = v₀² + 2aΔx
v² = (0 m/s)² + 2 (7.5 m/s²) (12 m)
v ≈ 13.4 m/s
Answer:
The current through the bulb when the flashlight is turned on is 0.55 A.
Explanation:
Given that,
You have a flashlight that takes four ideal 1.5 V batteries, voltage of the flashlight, V = 6 V
The resistance of bulb, R = 11 ohms
We need to find the current through the bulb when the flashlight is turned on. As per Ohms's law :
V = IR

So, the current through the bulb when the flashlight is turned on is 0.55 A. Hence, this is the required solution.
Answer:
The results is Li₂O
Explanation:
n a chemical reaction, the electron miner in the formula must be balanced, that is, the number of positive and negative charges is the same
In this case, oxygen has a valence of -2 that is, it can give two electrons and lithium has a valence of +1, therefore two lithium atoms are needed for the charges to be neutral, therefore the chemical formula is
The results is Li₂O
