How many steps are in a stride? two steps What is average stride length by height? In this activity you should have found this hypothesis to be pretty accurate. On average, adults have a step length of about 2.2 to 2.5 feet. In general, if you divide a person’s step length by their height, the […]
How does a catapult work science?
How does a catapult work science? A catapult works because energy can be converted from one type to another and transferred from one object to another. When you let go, this stored energy is released, converted into energy of motion and transferred to the missile (the launched object), which then flies through the air. What […]
Which is the power stroke in 4-stroke engine?
Which is the power stroke in 4-stroke engine? Four-stroke cycle used in gasoline/petrol engines: intake (1), compression (2), power (3), and exhaust (4). The right blue side is the intake port and the left brown side is the exhaust port. What happens in each stroke of a 4-stroke engine? An internal-combustion engine goes through four […]
What is the expression for net force net force?
What is the expression for net force net force? When a force is applied to the body, not only is the applied force acting, there are many other forces like gravitational force Fg, frictional force Ff and the normal force that balances the other force. Therefore, the net force formula is given by, FNet = […]
What is the difference between socialism and a pure command economy?
What is the difference between socialism and a pure command economy? explain the difference between socialism and a pure command economy. In socialism, the government owned some, but not all, factors of production. In a pure command economy, the government owns all factors of production. Which type of economic system is most likely to experience […]
What is the first thing a technician should do before performing diagnosis on any electrical circuit?
What is the first thing a technician should do before performing diagnosis on any electrical circuit? Perform starter circuit voltage drop tests; determine needed repairs. Disable the ignition and fuel system before performing these tests. Check the voltage drop between each component in the starter circuit while operating the starter motor. Voltage drop between each […]
How do you calculate maximum flow through a control valve?
How do you calculate maximum flow through a control valve? The volume flow rate for liquids can be calculated by multiplying the fluid velocity times the flow area. Thus, Cv is numerically equal to the number of U.S. gallons of water at 60°F that will flow through the valve in one minute when the pressure […]
What are the 5 stages of team development?
What are the 5 stages of team development? Tuckman’s model identifies the five stages through which groups progress: forming, storming, norming, performing, and adjourning. Each of the five stages of team development represents a step on the team-building ladder. During which stage does a team accomplish most of its significant work? adjourning stage What happens […]
What is the difference between friction and antifriction bearings?
What is the difference between friction and antifriction bearings? Friction bearings commonly use lubricating oil to separate the moving component from the mated non-moving bearing surface. An antifriction bearing is a bearing that contains moving elements to provide a low friction support surface for rotating or sliding surfaces. Why are ball and roller bearings called […]
What is redundancy work?
What is redundancy work? Redundancy occurs when employers reduce their workforce because a position is no longer required. “Redundancies are a form of dismissal, and can happen when an employee’s job no longer exists. This may be due to an employer needing to reduce their workforce, close the business, or certain work is no longer […]
