Answer:

The answer is screw x

Explanation:

A screw is an inclined plane that spirals around a cylinder. To help visualize this, imagine a playground slide that sprirals around a central pole. The threads on a screw are the outside edge of a plane that wraps around the screw's central axis.

The closer together a screw's threads are, the longer the inclined plane. The longer the inclined plane, the less effort force required to turn the screw. The screw in image X requires the least amount of effort force to turn because its threads are the closest together.

Answer:

Screw X

Explanation:

  • In the screw x, the threads of the inclined plane are closer together. Therefore this screw has a greater mechanical advantage and hence it is easier to turn than the other screws.
  • Therefore,it takes less force to penetrate the wood with the screw X.

Describe the kinetic molecular theory
tatuchka [14]
The kinetic theory of gases is a simple, historically significant model of the thermodynamic behavior of gases, with which many principal concepts of thermodynamics were established. The model describes a gas as a large number of identical submicroscopic particles, all of which are in constant, rapid, random motion

The electric current in a wire is 1.5A. How many electrons flow past a given point in a time of 2s?
kipiarov [429]

Answer:

The amount of electrons that flow in the given time is 3.0 C.

Explanation:

An electric current is defined as the ratio of the quantity of charge flowing through a conductor to the time taken.

i.e           I = \frac{Q}{t} ...................(1)

It is measure in Amperes and can be measured in the laboratory by the use of an ammeter.

In the given question, I = 1.5A, t = 2s, find Q.

From equation 1,

            Q = I × t

                = 1.5 × 2

               = 3.0 Coulombs

The amount of electrons that flow in the given time is 3.0 C.

A test charge of -1.4 x 10-7 coulombs experiences a force of 5.4 x 10-1 newtons. Calculate the magnitude of the electric field c
VARVARA [1.3K]

Answer:

3.86×10⁶ Newton/coulombs

Explaination:

Applying,

E = F/q....................... Equation 1

Where E = Electric Field, F  = Force, q = charge.

From the question,

Given: F = 5.4×10⁻¹ N, q = -1.4×10⁻⁷ coulombs

Substitute these values into equation 1

E = 5.4×10⁻¹/ -1.4×10⁻⁷

E = -3.86×10⁶ Newtons/coulombs

Hence the magnitude of the electric field created by the

negative test charge is 3.86×10⁶ Newton/coulombs
