Wheel & Axle – On lawnmowers and wheelbarrow. Also, found in cabinet door glides and on appliances. Another common example – door knobs and even inside those locksets.

Lever – The bottle opener. Tools – the crowbar, and scissors or pliers. Double Levers – a door, a toilet seat, a broom.

Pulley – Old wood windows, some garage doors, workshop or garage lifting systems.

Wedge – The shim – used throughout the home in construction. For example, when installing doors, windows, cabinets, etc. Sometimes used to level furniture or chairs.

Now for deeper look at the simple machines found around our homes.

The hope this will be helpful.

The direction of deflection of an electron beam in a magnetic field can be determined by which of the following?

amid [387]

Answer:

Right Hand Rule

Explanation:

When a charged particle travels in a magnetic field, it experiences a force whose magnitude is given by:

$F=qvBsin\theta$

where

q is the charge of the particle

v is the velocity

B is the magnetic field strength

$\theta$ is the angle between the directions of v and B

The direction of the force can be determined by using the Right Hand Rule, as follows:

- index finger: this should be put in the direction of the velocity

- middle finger: this should be put in the direction of the magnetic field

- thumb: this will give the direction of the force -> however, for a negative charge (as the electron) the direction must be reversed, so it will be opposite.

Explain what it means when we say a substance is magnetic

galben [10]

A magnetic substance has magnetic fields. These fields start at the North Pole wrap aroundthe magnet, and terminate at the south pole of the magnet. All magnetic substances have <span>north and south poles.</span>
