In physics class, Anne is designing a small circuit that can operate a mixer. Identify the devices she should use in the circuit
Lubov Fominskaja [6]

To operate a mixer circuit , Anne should use a (motor, buzzer, bulb, or battery) to transfer electric energy into motion. She should also use a (switch, resistor, buzzer, or bulb) to start and stop the flow of current.

An electric-powered circuit consists of a device that gives energy to the charged particles constituting the modern-day, consisting of a battery or a generator; devices that use cutting-edge, including lamps, electric cars, or computer systems; and the connecting wires or transmission traces.

An electrical circuit is an interconnection of electrical components or a version of such an interconnection, consisting of electrical elements. an electrical circuit is a network along with a closed loop, giving a go-back direction for the cutting-edge.

An electrical circuit consists of a source of electrical strength, two wires that can convey electric power present day, and a mild bulb. One stop of both the wires is hooked up to the terminal of a mobile at the same time as their free ends are related to the light bulb. the electric circuit is damaged while the bulb is switched off.

Which of acceleration, age, speed, temperature, and velocity are vector quantities?.
ollegr [7]

Velocity and acceleration are vector quantities whereas speed, temperature and age are not.

<h3>What is a vector quantity?</h3>

Vector is a quantity that has both magnitude and direction and is represented by an arrow whose direction is same as that of the quantity and length is proportional to the quantity's magnitude.

Vector has magnitude and direction but it does not have position. Velocity and acceleration both are vector quantities as they have magnitude and direction.

If the speed of an object remains same but direction changes then the object is accelerating. It is important to remember that acceleration and velocity aren't always in the same direction.

When hiking at altitude, the air pressure drops to 825,000Pa. Solve the force that site exerts against the side of a rectangular
OLga [1]

Answer:

The force is 1237500N

Explanation:

We can apply the following expression

pressure=\frac{Force}{Area}

To find the area of rectangular tent wall:

Area=length *width\\Area=2.00m*0.750m\\Area=1.5m^{2}

Now to find the force:

pressure=825,000pa

pressure=\frac{Force}{Area}

Force=pressure*Area\\Force=825000pa*1.5m^{2} \\Force=1237500N
