Answer:

' In layman's terms, the k variable in Hooke's law (F = -kx) indicates stiffness and strength. The higher the value of k, the more force is needed to stretch an object to a given length. This value is dependent on the object's material alongside its shape and Proportons

Answer:

Solubility in gasses and liquids increase as pressure increases. This is due to colligative properties. The nitrogen gas levels would increase the farther the diver dives due to the increase of pressure causing the solubility of the nitrogen to increase, thus increasing the amount of it as you go deeper in the ocean.

Explanation:

As they plummet down, the driver would be in more risk. The solubility of gases and liquids increases as pressure increases. This is due to the existence of colligative properties. The nitrogen gas levels grow when the diver descends further into the water due to increased pressure, which causes the nitrogen's solubility to rise, increasing the amount of nitrogen present.

One Newton can be defined as the amount of force that would give a mass of one kilogram an acceleration of one meter per second per second.

The definition of force in physics is: The push or pull on a massed object changes its velocity.

An external force is an agent that has the power to alter the resting or moving condition of a body. It has a direction and a magnitude.

A spring balance can be used to calculate the Force. Newton is the SI unit of force.

From Newton's second law of motion: we know that:

Force = mass × acceleration

Now in SI system:

Unit of force is Newton.

Unit of mass is kg and unit of acceleration is meter per square second.

Hence, one Newton force can be defined as:

The required force to generate 1 meter per square second acceleration on an  object of mass one kilogram.

Select the checkboxes: Forces, Sum of Forces, Values, Masses and Speed. Kee the knob that regulates the friction at the center of the scale. Forces Sum of Forces Values Masses

3. Start to push the box, increasing the force applied on the box slowly. There is a force that is opposite to the force you are applying. What is the name of the force opposing to the motion? 4. Once the box start moving, the magnitude of the resultant force increase instantaneously. How do you explain that? 5. Push the box and find the force needed to make the box to start moving. Add more mass (box, kid, man,refrigerator, basket as needed) and repeat the procedure such that you complete the table below.

Explanation:

The forces act on skateboard when we push it are , external force of 500N and friction force because of the surface.

The stationary object will remain stationary or the subject in the motion will keep its motion until or unless the external force is not applied .

Answer:

Vectors are defined as quantities which are fully described by both their magnitude and direction. By definition, a vector has a direction associated with it.

Explanation:

is this what you want?

Force is a vector quantity hence it can be resolved into a vertical and a horizontal components.

1) The horizontal component of the applied force is given by;

Fnet = F cos θ

Fnet = 70.0N × cos (45.0)

Fnet = 49.5 N

2) The horizontal component of the frictional force is;

F = -Ff + mgsinθ

F = applied force

Ff =mgsinθ - F

Ff = (11 × 10 × sin 45) - 49.5

Ff = 28.3 N

Horizontal component of Ff

28.3 N cos 45 = 19.9 N

3) The applied force is given by;

F = 11 Kg ×  1.00m/s^2 = 11.0 N

Velocity and displacement take direction of motion into account while distance does not take direction of motion into account.

Vector quantities take into account both magnitude and direction of motion while scalar quantities only take the magnitude of motion into account. In describing the motion of an object, we use terms such as; velocity, distance, displacement etc.

Looking at the options provided in the question, displacement and velocity are vectors hence they take the direction of motion into account. Distance is a scalar quantity hence it does not take direction of motion into account.

Answer:

Pressure is inversely proportional to the area of the surface. While a blunt knife has more area coming in contact than a sharp knife and the pressure exerted by the blunt knife will be less as compared to that of a sharp knife. Therefore it is easier to cut with a sharp knife.
