2. Two pulleys 10 in. diameter and 25 in. diameter is connected by an open belt with center distance of 40 in. Find the belt length needed to connect them.
1. A lathe having a 5-step pulley is driven by a belt, assumed to be crossed, from a pulley of the same size on the countershaft. The countershaft is to have a constant speed, and the lathe is to have speeds of 60 rpm and 135 rpm when the belt is on the steps either side of the center step. If the minimum speed is 40 rpm and the smallest diameter is 4 in., find the proper speed of the countershaft, maximum speed of the lathe, and the diameter of all steps on the pulleys.
If 51% of the population carries at least one copy of the recessive allele. what is the predicted frequency of the population expressing the dominant phenotype?
The national earthquake information center characterizes the effect of
earthquakes based on Richter scale numbers. Write a C program to implement
the following decision table
.
Ritcher scale number (n)
Characterization
n<5.0
Little or no damage
5.0 <= n < 5.5
Some damage
5.5 <= n < 6.5
Serious damage: Walls may crack or fall
6.5 <= n < 7.5
Disaster: houses and buildings may collapse
Higher
Catastrophic: most
buildings destroyed

A capacitor is used in a typical flash for a “point-and-shoot” camera. The figure shows a circuit for a camera flash, where a 1.5V cell battery is charging the 2000 μF capacitor. When a flash is required, the energy stored in the capacitor is made to discharge through a discharge tube in0.001 s, giving a powerful flash.
- If we change the battery into a 5.0V cell, instead of using 1.5V cell, how much energy will be stored in the capacitor?
- If the flash lasts for about 0.001 s, what is the power delivered by the capacitor during this brief time?
a solution of 3.80 g of CH3COOH in 80.0 g C6H6 has a freezing point of 3.50°C. calculate molar mass of the solute (CH3COOH). the normal freezing point of pure benzene is 5.50°C
