Answer to Problem 1P

The absolute zero in the new scale is 738°N .

Explanation of Solution

Given info: The normal human body temperature in degree Fahrenheit is 98.6°F . In the new scale the normal body temperature and freezing point of water is 100°N and 0°N respectively. The melting point of mercury is 37.9°F . The highest temperature is 134.1°F .

Write the expression to convert the temperature scale.

N=aF+b (1)

Here,

N is the temperature in °N .

a,b are constants.

F is the temperature in degree Fahrenheit.

Substitute 98.6°F for F and 100°N for N in equation (1).

100°F=a(98.6°F)+b (2)

The freezing point of water in degree Fahrenheit is 32°F .

Substitute 32°F for F and 0°N for N in equation (1).

0N=a(32°F)+b (3)

Solve equation (2) and (3).

a=1.5b=48.04

The temperature of absolute zero in degree Fahrenheit is 460 .

Substitute 460 for F , 1.5 for a and 48.04 for b in equation (1).

N=1.5(460)+(48.04)=738N

Conclusion:

Therefore, the absolute zero in the new scale is 738°N .

Answer to Problem 1P

The melting point of mercury in new scale is 105°N .

Explanation of Solution

Given info: The normal human body temperature in degree Fahrenheit is 98.6°F . In the new scale the normal body temperature and freezing point of water is 100°N and 0°N respectively. The melting point of mercury is 37.9°F . The highest temperature is 134.1°F .

Write the expression to convert the temperature scale.

N=aF+b (1)

Substitute 37.9 for F , 1.5 for a and 48.04 for b in equation (1).

N=1.5(37.9)+(48.04)=105

Conclusion:

Therefore, the melting point of mercury in new scale is 105°N .

Answer to Problem 1P

The boiling point of water in new scale is 270°N .

Explanation of Solution

Given info: The normal human body temperature in degree Fahrenheit is 98.6°F . In the new scale the normal body temperature and freezing point of water is 100°N and 0°N respectively. The melting point of mercury is 37.9°F . The highest temperature is 134.1°F .

The boiling point of water in degree Fahrenheit is 212 .

Write the expression to convert the temperature scale.

N=aF+b (1)

Substitute 212 for F , 1.5 for a and 48.04 for b in equation (1).

N=1.5(212)+(48.04)=270

Conclusion:

Therefore, the boiling point of water in new scale is 270°N .

Answer to Problem 1P

The highest recorded air temperature on Earth’s surface in new scale is 153°N .

Explanation of Solution

Given info: The normal human body temperature in degree Fahrenheit is 98.6°F . In the new scale the normal body temperature and freezing point of water is 100°N and 0°N respectively. The melting point of mercury is 37.9°F . The highest temperature is 134.1°F .

Write the expression to convert the temperature scale.

N=aF+b (1)

Substitute 134.1 for F , 1.5 for a and 48.04 for b in equation (1).

N=1.5(134.1)+(48.04)=153

Conclusion:

Therefore, the highest recorded air temperature on Earth’s surface in new scale is 153°N .

The figure below shows, at left, a solid disk of radius R = 0.600 m and mass 75.0 kg. Tu Mounted directly to it and coaxial with it is a pulley with a much smaller mass and a radius of r = 0.230 m. The disk and pulley assembly are on a frictionless axle. A belt is wrapped around the pulley and connected to an electric motor as shown on the right. The turning motor gives the disk and pulley a clockwise angular acceleration of 1.67 rad/s². The tension T in the upper (taut) segment of the belt is 145 N. (a) What is the tension (in N) in the lower (slack) segment of the belt? N (b) What If? You replace the belt with a different one (one slightly longer and looser, but still tight enough that it does not sag). You again turn on the motor so that the disk accelerates clockwise. The upper segment of the belt once again has a tension of 145 N, but now the tension in the lower belt is exactly zero. What is the magnitude of the angular acceleration (in rad/s²)? rad/s²
