7. Consider a vacuum region, 0 < x < a, bounded by two grounded perfectly conducting walls at x = 0 and x = a. A surface charge density $\rho_0 \sin(\frac{3\pi}{a}x)$ is placed on y = 0, 0 < x < a. a) What is the electrostatic potential in the region 0 < x < a?(10%) b) What is the total charge (per unit length in z) on the surface of the conductor at x = 0? (10%)

Which of the following statements about the muscle cell contractions is not true: In a relaxed state the, the thick and thin filaments do not fully overlap (only at the sides of the A band) Cross bridge formation occurs when myosin heads bind to actin filaments Contraction is stimulated by the binding of sodium to troponin When troponin changes shape, tropomyosin no longer blocks binding sites on actin for myosin. The creation of a cross bridge requires the hydrolysis of an ATP molecule

Text: RSA Decryption Given a public key (exponent and modulus) and ciphertext (this RSA uses RSA/ECB/NoPadding), the modulus is 512 bits long. The question suggests either a dictionary attack or factorization (an English text file is provided for the dictionary attack). I have assumed that p and q are close to each other, so I used the Fermat factorization method. However, after 2 hours, the program is still running. Therefore, I think a dictionary attack is the only way, but I am clueless about the process. Please help. Thank you.
