A 5.6 g ice cube (at 0 $^\circ$C) is placed into 194 g of water initially at 25 $^\circ$C. If the heat absorbed for melting the ice comes only from the 194 g of water, what is the temperature change of the 194 g of water? The specific heat capacity for water is 4.184 J/g$^\circ$C. Express your answer in degrees Celsius to three significant figures. $\Delta T = $ ? $^\circ$C

A person’s heart rate increases in proportion to the intensity of a frightening stimulus. b. A person hears a sudden loud noise, and their startle response is just as strong as if the noise had been slightly louder or softer. c. When exposed to a gradually increasing noise, a person experiences a corresponding gradual increase in anxiety. d.

A file of 106 bits is transmitted in blocks of 103 bits. Assume that bit errors and successive transmissions are independent of each other. The bit error rate for the channel is 10−6. Assume that at most one single-bit error occurs per block. Answer the questions below to compare the overhead associated with error detection and error correction. a. What is the expected number of errors in a block? b. Assume that single-bit (per block) parity is used for error detection. If an error is detected by the receiver in a particular block, that block is retransmitted. Assume that a retransmission is immune to error, i.e., at most one retransmission will be necessary for a given block. Determine the total number of bits that the source should expect to send for successful receipt of the file by the destination. This will include all bits associated with error detection and retransmission. c. Now assume that instead of error detection, single-bit error correction is used. Determine the total number of bits that the source should expect to send for successful receipt of the file by the destination. Assume that the error correction method uses the minimum number of bits that can be used to correct a single error. d. Assume that you don’t know the bit error rate, but you want to determine the maximum error rate at which error detection with single-bit parity followed by retransmission in case of error (part b), is more efficient than single-bit error correction with an optimal code (part c)? I am not asking you to find the value. All I need is for you to show the equation or identity that you would use to find the break-even error rate.
