Answer:

In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction

Answer:

Newton's Law of Motion

1- Every object persists in its state of rest or uniform motion -­ in a straight line unless it is compelled to change that state by forces impressed on it.

2- Force is equal to the change in momentum per change in time. For a constant mass, force equals mass times acceleration.

3- For every action, there is an equal and opposite reaction.

A mechanic changing the spark plugs in a car notes that the instruction manual calls for a torque with a magnitude of
Papessa [141]

The magnitude (in N) of the force she must exert on the wrench is 150.1 N.

<h3>Force exerted by the wrench</h3>

The force exerted by the wrench is calculated using torque formula as follows;

torque, τ = F x r x sinθ

where;

  • F is the applied force
  • r is the perpendicular distance if force applied

F =  τ /(r sinθ)

F = (39) / (0.3 sin 60)

F = 150.1 N

Thus, the magnitude (in N) of the force she must exert on the wrench is 150.1 N.

In a few sentences, describe how the thermostat utilizes a bimetallic strip in order to turn a furnace on and off in one or two
Vilka [71]

Answer:

Explanation:

Bimetallic strips are used in thermostats for measuring and controlling temperature. The strip is connected to a switch and as the temperature changes, the strip flexes and opens or closes a contact. They are also used in ovens for measuring temperature. An electromechanical thermostat typically contains either a bi-metal coil or a metal strip. When the temperature changes, this coil or strip will move, causing a vial containing mercury to tip to one side. The mercury flows to one end of the vial, signaling that the heating or cooling needs to be turned on.
