EXERCISE 6 1. A shopper in a supermarket pushes a cart with a force of 35 N directed at an angle of 25° downward from the horizontal. Find the work done by the shopper as she moves down a 50-m length of aisle. 1.6 kJ 2. A horizontal force of 150 N is used to push a 40.0-kg packing crate a distance of 6.00 m on a rough horizontal surface. If the crate moves at constant speed‚ find (a) the work done by the 150-N force and (b) the coefficient of kinetic friction between the crate and surface. 900J

Physiological Effects of Steroids and Steroid Abuse Competition in sports is absolutely incredible. Some athletes go as far as using drugs illegally such as anabolic steroids‚ a synthetic derivative of the male hormone testosterone. However‚ major sports bodies like the Olympics‚ the NBA‚ the NFL‚ and the NHL ban the use of such substances. For this reason‚ it is helpful to know the physiological effects of steroids as well as negative consequences of steroid abuse. In their experiment‚ Anttila

he Respiratory System Fig 4. Horse’s respiratory system The functions of the respiratory system are to provide the body with oxygen‚ to remove carbon dioxide from the body‚ to control temperature (breathing out warm air and breathing in cool air)‚ to eliminate water‚ to communicate (Voice production) and sensory input (Smell/ touch- nose hairs). The respiratory system consists of the nostrils‚ pharynx‚ larynx‚ Nostrils The nostrils expand to allow air to enter the respiratory system‚ hairs within

Air enters the nose by passing through the external nares or nostrils. The mucosa lining the nasal cavity‚ called the respiratory mucosa‚ warms the air as it flows pa Respiratory physiology The major function of the respiratory system is to supply the body with oxygen and to dispose of carbon dioxide. To do this‚ at least four distinct events‚ collectively called respiration‚ must occur: 1. Pulmonary ventilation Air must move into and out of the lungs so that the gases in

Cardiovascular System Anatomy & Physiology The heart is the pump responsible for maintaining adequate circulation of oxygenated blood around the vascular network of the body. It is a four-chamber pump‚ with the right side receiving deoxygenated blood from the body at low presure and pumping it to the lungs (the pulmonary circulation) and the left side receiving oxygenated blood from the lungs and pumping it at high pressure around the body (the systemic circulation). The myocardium (cardiac
