Answer: The particle model, because only high-energy frequencies of lights can remove electrons.
Explanation: just did the test and got it right :)
Answer:
150A
Explanation:
Given parameters:
Potential difference = 120V
Resistance = 0.8Ω
Unknown:
Current = ?
Solution:
From ohm's law;
I =
I is the current
V is the voltage
R is the resistance
Now insert the parameters and solve;
I = = 150A
Answer:
Idk but that is concerning and do you have a cat??
Explanation:
The weight required to stretch the spring 12.5 cm is 7.5 N (Option A)
<h3>Data obtained from the question</h3>
- Initial weight (W₁) = 3 N
- Initial Length (L₁) = 5 cm
- New length (L₂) = 12.5 cm
- New Weight (W₂) =?
<h3>How to determine the new weight </h3>
The new weight required to stretch the spring can be obtained as follow:
W₁ / L₁ = W₂ / L₂
3 / 5 = W₂ / 12.5
Cross multiply
W₂ × 5 = 3 × 12.5
Divide both sides by 5
W₂ = (3 × 12.5) / 5
W₂ = 7.5 N
