Analysis of the June 2013 Physics Regents Answers
Understanding the answers to the June 2013 Physics Regents exam is essential for both students and educators. Analyzing the answers helps students identify areas of strength and weakness, enabling them to focus their studies more effectively. Here is a breakdown of the answers to key questions from the exam.
Sample Questions and Answers
1. Question 1: A car accelerates uniformly from rest to a speed of 20 m/s in 5 seconds. What is the acceleration of the car?
- Answer: To find the acceleration, use the formula:
\[
a = \frac{v_f - v_i}{t}
\]
Where \(v_f = 20 \, \text{m/s}\), \(v_i = 0 \, \text{m/s}\), and \(t = 5 \, \text{s}\):
\[
a = \frac{20 \, \text{m/s} - 0 \, \text{m/s}}{5 \, \text{s}} = 4 \, \text{m/s}^2
\]
2. Question 2: A sound wave travels through air at a speed of 340 m/s. If the frequency of the sound wave is 680 Hz, what is the wavelength?
- Answer: The wavelength can be found using the formula:
\[
\lambda = \frac{v}{f}
\]
Where \(v = 340 \, \text{m/s}\) and \(f = 680 \, \text{Hz}\):
\[
\lambda = \frac{340 \, \text{m/s}}{680 \, \text{Hz}} = 0.5 \, \text{m}
\]
3. Question 3: In a simple circuit, a 12V battery is connected to a resistor of 4Ω. What is the current flowing through the resistor?
- Answer: Using Ohm's law:
\[
I = \frac{V}{R}
\]
Where \(V = 12 \, \text{V}\) and \(R = 4 \, \Omega\):
\[
I = \frac{12 \, \text{V}}{4 \, \Omega} = 3 \, \text{A}
\]
4. Question 4: A 2 kg object is lifted to a height of 5 m. What is the gravitational potential energy of the object?
- Answer: The gravitational potential energy (GPE) can be calculated using:
\[
GPE = mgh
\]
Where \(m = 2 \, \text{kg}\), \(g = 9.8 \, \text{m/s}^2\), and \(h = 5 \, \text{m}\):
\[
GPE = 2 \, \text{kg} \times 9.8 \, \text{m/s}^2 \times 5 \, \text{m} = 98 \, \text{J}
\]
