Plz help me!!!! A spring is connected to a wall as shown below. A mass on a horizontal surface is connected to the springs and p

Answer:

320 N/m

Explanation:

F = k·Δx

where

F is the restoring force of the spring

k is the proportionality constant called the ‘spring constant’

Δx is the change in the spring’s position due to the deformation.

You need the k so

25 cm= 0.25m

k=F/∆x = 80/0.25 = 320 N/m

which observation about the Mid-Atlantic Ridge region provides the best evidence of the seafloor has been spreading over for mil
Kitty [74]

Magnetic stripes on the sea floor

Explanation:

The observation of magnetic stripes patterns at the region of the Mid-Atlantic Ridge galvanized the evidence that sea floor spreading has been on for several millions of years.

  • Geomagnetic field of the earth is similar to that of bar magnet having the north and south pole.
  • It originates from the movement of iron-nickel within the outer core.
  • This geomagnetic field causes the magnetization of magnetic minerals in rock.
  • When freshly formed magma is brought to the surface at the mid oceanic ridge area, the prevailing magnetic field causes the magnetic minerals in the magma to cool in such a way that they align their domains to that of the field.
  • The magnetic field of the earth can reverse and take different geometry. Sometimes, its intensity is very strong and at other times it is weak.
  • The magnetic minerals in melts bear these records.
  • As new materials are brought up, they get magnetized.

Why do stars twinkle​
vlada-n [284]

As light from a star races through our atmosphere, it bounces and bumps through the different layers, bending the light before you see it. Since the hot and cold layers of air keep moving, the bending of the light changes too, which causes the star's appearance to wobble or twinkle.

Explain what is meant by “field” and compare the properties of gravitational, electric, and magnetic forces in terms of particle
notsponge [240]
Field in this context refers to a region of the space to which corresponds a value.

There is a gravitational field around the earth, because a mass m placed at any point around the earth will be atracted (gravitational force) by it.

There is an electric field in a point when a charge placed there feels an electric force.

The gravitational field is proportional to the value of the mass of the object that produces it.

The electric field is proportional to the magnitude of the charge of the particle that produces it.

The gravitational field is always attractive. The electric field may be attractive or repulsive.

Both fields are proportional to the inverse of the squared distance.

The magnetic field is created when a charge is in movement,i.e a charge in movement will create a magnetid fiedl around it that will act and create a magnetic force over other charge also in movement.

The magnetic field is proportional to the product of the charge times its velocity and inversely proportional to the squared distance. The force generated my be attractive or repulsive.

Why is the sum of forces/net force less than the applied force? Think about the direction of the forces in your answer
Reil [10]

Answer:

he same direction the magnitude of the resultant is equal to the scalar sum of the magnitude of the forces, but if they are applied in different directions the magnitude must be found using the Pythagorean theorem

Explanation:

When there are several applied forces, if they are all in the same direction the magnitude of the resultant is equal to the scalar sum of the magnitude of the forces, but if they are applied in different directions the magnitude must be found using the Pythagorean theorem, so which the resulting dowry is less than the sum of the magnitudes.

Let's carry out an example with two forces, F1 and F2 of equal magnitudes

if they are in the same direction

           F_total = F₁ + F₂ = 2 F

if they are at 90º

          F_total = \sqrt{F_1^2 + F_2^2}= \sqrt{2}  \ F

if they are at 180º

          F_total = F₁ -F₂ = 0
