What would you tell the person who is trying to loosen the rusty?
What would you tell the person who is trying to loosen the rusty nut with the wrench? Move your hand farther from the nut. Four weights are tied together and hung from the ceiling.
What does AC stand for Asvab?
Alternating Current. The abbreviation AC stands for. DIODE. Restricts a currents flow to a single direction.
Why are the hoops closer together near the bottom?
Why are the hoops closer together at the bottom of the tank? The water pressure pushing against the sides of the tank is greater near the bottom.
Why are spaces placed between slabs of concrete?
Contraction/control joints are placed in concrete slabs to control random cracking. A fresh concrete mixture is a fluid, plastic mass that can be molded into virtually any shape, but as the material hardens there is a reduction in volume or shrinkage. The result is cracking of the concrete.
What is best to say about a runner who is running at a constant velocity?
What is BEST to say about a runner who is running at a constant velocity? Their acceleration is zero.
How does the force needed to turn the wrench change if you increase the lever arm?
It decreases. How does the force needed to turn the wrench will change if you increase the lever arm? It increases.
Which device restricts flow to a single direction?
A diode serves this function with electricity. The diode, just like a one-way flapper valve, restricts the flow to a single direction.
What type of electricity used to power a car radio is typically?
Car radios use direct current (DC) voltage to power their electronics while home electronics use alternating current (AC) with a much higher voltage. In fact, car radios can work down to somewhere around 11 volts DC, with 12V to 14.4V being typical when a vehicle’s engine is running.
When wire conductors are coated with solder The process is called?
Tinning is a process of using a soldering iron to melt solder around a stranded electrical wire.
What is centrifugal force quizlet?
Centrifugal Force. an apparent force that acts outward on a body moving around a center, arising from the body’s inertia. ( non-inertia).
Which of the objects has the most structural strength?
There are several shapes that are used when strength is important. The arc (think: circle) is the strongest structural shape, and in nature, the sphere is the strongest 3-d shape.
How many minutes will it take for the airplane to land at an airport 3000 feet above sea level?
The minimum practical time (assuming 30,000 foot altitude and a 3000 feet-per-minute [fpm] descent rate) would be 10 minutes, though this is not the case for a few reasons. First – 3000 fpm is at the agressive end of the spectrum, and actual rates are probably between 1000-2000 fpm (taking us up to 15-30 minutes).
How does a round stone become smooth?
Abrasion causes rocks to grind down and become rounder as they are transported down the river. … First, abrasion makes a rock round. Then, only when the rock is smooth, does abrasion act to make it smaller in diameter.
What is the tool shown Asvab?
The tool pictured is a hole cutter bit, also known as a hole saw.
What is best to say about a runner who is running?
Velocity is a time-dependent property of an object, while acceleration is not. What is BEST to say about a runner who is running at a constant velocity? Their acceleration is positive.
What distinguishes the three different classes of levers?
The three different classes of levers in the body are differentiated by where the resistance (the weight) occurs in relation to the axis (the fulcrum).
Which of the following best describes a body in equilibrium quizlet?
Which of the following BEST describes a body in equilibrium? B. All forces acting on a body are balanced. What differentiates extension from hyperextension?.
What does it mean if the torque of a force is positive?
Note that each force that acts in the counterclockwise direction has a positive torque, whereas each force that acts in the clockwise direction has a negative torque. The torque is greater when the distance, force, or perpendicular components are greater.
What does it mean when torque is zero?
Torque is zero when body is stationary or rotating at a constant rotational velocity external torque must be zero. This is from Newton’s First Law expressed rotationally.
Which device restricts current flow?
A diode is a semiconductor device that essentially acts as a one-way switch for current. It allows current to flow easily in one direction, but severely restricts current from flowing in the opposite direction.
What does a resistor do?
A resistor is a passive electrical component with the primary function to limit the flow of electric current.
What is the purpose of a diode?
diode, an electrical component that allows the flow of current in only one direction. In circuit diagrams, a diode is represented by a triangle with a line across one vertex.
What kind of electricity do cars use?
Most of the components in a vehicle will run using DC currents. Therefore, the car’s battery will use a DC current to power these electronic components.
How can I power my car radio at home?
You need a 12V power cord to use your car stereo power supply for home use, but you can easily get that from a hardware store. Cut the end of the power cord and connect the black wire with the line of white around the stereo’s red and yellow wires. Make sure every wire is completely covered before you plug it in.
How much power does a car radio use?
The maximum output power per channel for average car stereos ranks at about 10 watts RMS. It’s a decent setup to shun out usual traffic noise without causing too much distortion. If you get a compact 4-channel amp, you can dramatically increase this performance but at the cost of some extra power.
