Answer:
mass of the fish is 8.11 kg
Explanation:
As we know that the frequency of oscillation of spring block system is given as
here we know that the reading of scale varies from 0 to 155 N from length varies from x = 0 to x = 10 cm
Now we have
so now we have
so mass of the fish is 8.11 kg
A squirrel running up towards the trunk of a tree transforms kinetic energy into gravitational potential energy. Again lifting heavyweight over one's head also requires gravitational potential energy. Pen being held above the table is another instance of Potential Energy. The person walking upstairs would also require more kinetic potential energy.
<u>Explanation</u>
- Gravitational potential energy is the energy that any object possesses owing to its location on the ground surface. The gravitational potential, therefore, happens to be at its maximum level for objects near the earth surface where acceleration is unchanged at 9.8 m/s^2.
- In very simple terms, Gravitational potential energy is that form of energy that is present due to the location of the specific object above the earth's surface. Further, the volume and weight of the object are also very instrumental in determining its gravitational potential energy since the more voluminous the object the greater the kinetic potential energy.
- In the above question, if the squirrel running up towards the trunk of a tree, would require more energy to move up hence more kinetic potential energy. In the same weightlifter lifting weight above his head would require energy to lift it and hence more kinetic potential energy. Again, a person walking upstairs would require more energy which is said to be the potential kinetic energy
Answer: Density, pressure, and temperature all increase as you go deeper into the Earth.
Explanation: Explanation: As you go deeper in depth, pressure increases. Density = mass/volume. The layers beneath us due to pressure get packed to the point of being very dense.
P-waves pass through both mantle and core, but are slowed and refracted at the mantle / core boundary at a depth of 2900 km. S-waves passing from the mantle to the core are absorbed because shear waves cannot be transmitted through liquids. ... The core has a radius of 3470 km.
