Objects of equal mass are oscillating up and down in simple harmonic motion on two different vertical springs. The spring consta
olga55 [171]

Answer:1080 N/m

Explanation:

Given

Spring constant of first Spring K_1=245 N/m

mass of both the system is same

Both system have same maximum velocity

if x=A\sin \omega t is general equation of SHM

then maximum velocity is given by

v_{max}=A\omega

\omega =\sqrt{\frac{k}{m}}

v_1_{max}=A_1\omega _1

\omega _1=\sqrt{\frac{k_1}{m}}

similarly \omega _2=\sqrt{\frac{k_2}{m}}

also A_1=2A_2

so A_1\times \sqrt{\frac{k_1}{m}}=A_2\times \sqrt{\frac{k_2}{m}}

2\times \sqrt{k_1}=\sqrt{k_2}

k_2=4k_1

k_2=4\times 245=1080 N/m

What are some contact forces in the geosphere?
aivan3 [116]

1) Example of contact force: friction

2) Examples of non-contact forces: gravity and electromagnetic force

Explanation:

1)

Contact forces are forces that acts only when the objects involved are touching.

An example of contact force in the geosphere is friction. Friction is a force that acts when two objects slide past each other, and the surfaces of the two objects are in contact. Due to the presence of "microbumps" on the two surfaces, there is a resistive force opposing the motion of the two objects, and this force is called friction.

Friction also acts when an object is moving through a fluid, although it takes a different name: resistance. Also in this case, the resistance acts in the direction opposite to the motion of the object, slowing it down.

2)

Non-contact forces are forces that act from a distance, therefore they act even when the objects involved are not touching.

Examples of non-contact forces are:

  • Gravitational force: this is an attractive force that acts between any object with mass. Its magnitude is directly proportional to the product of the masses of the two objects and inversely proportional to the square of the distance between the two objects.
  • Electromagnetic force: this is a force exerted between electrically charged objects. Its magnitude is directly proportional to the product of the two charges and inversely proportional to the square of the distance between the charges. It can be attractive (if the charges have opposite sign) or repulsive (if the charges have same sign).

A rubber ball and a steel ball are dropped from the same height onto a concrete floor. They have the same mass, and lets assume
Mkey [24]

Answer:

The average forces would be the same

Explanation:

Both have the same velocity on impact as they fell from the same height.

Both have the same velocity after the bounce because they reach the same height.

Both have the same mass

Both will thus experience the same impulse because both have the same change in momentum.

Therefore both experience the same average force.

What kind of waves are present during an earthquake? ...
Brrunno [24]

Answer:

1. The two main types of waves are body waves and surface waves. Body waves can travel through the earth's inner layers, but surface waves can only move along the surface of the planet like ripples on water. Earthquakes radiate seismic energy as both body and surface waves.

2. potential energy

3. Newton's second law of motion is F = ma, or force is equal to mass times acceleration.

4. Refraction is the bending of light

5. Density uses the formula p=m/V, or density (p) is equal to mass (m) divided by volume (V). Density is defined as mass per unit volume.

Elanso [62]
<span>The amount of dissolved oxygen in water may decrease because of the increase in organic matter in the water. <span>Aquatic organisms breathe and use oxygen. Large amounts of oxygen are consumed by the decomposition of bacteria (when there are large amounts of dead matter to decompose, there will be a significant number of bacteria). Examples: dead organic matter (algae), wastewater, garden waste, oils and fats, all this results in a decrease in dissolved oxygen in the water.</span></span>
