High temperature and pressure tend to favor flow rather than breakage, so it is surprising that large, very deep earthquakes are sometimes observed, occurring in warm places where the pressure is high. What is accurate about these rare, deep earthquakes?.

Answers

They happen at subduction zones, where shifting mineral assemblages appear to "implode" as a result of increased pressure on the rock as it is subducted deeper.

The notion that is currently preferred is "Implosion." The building blocks often reorganize to take up less space as subduction zones move rocks deeper where pressure is stronger, moving from, say, a one-on-top-of-another pattern to a fit-in-the-gap-between-those-below pattern. This might sometimes seem to happen gradually before happening abruptly (I can't move till my neighbor does...), resulting in an implosion. Where temperatures and pressures are just so high that we don't imagine rocks can break, the largest, deepest earthquakes occur. Nowhere near as deep as the earthquakes, humans have never dug a hole. Atomic bomb testing has mostly ended. A large earthquake is also much larger than a large atomic weapon.)

The Moment of Inertia of skater of mass 58 Kg with approximated radius of 0.102 m will be 0.301 kg m².will be 0.301 kg m².

We have a 58 kg skater who is approximated as a cylinder that has a radius of 0.102 m.

We have to determine the Moment of Inertia of the of the skater.

What is Moment of Inertia? What is its general formula?

Moment of inertia is the property of the body by which it resists angular acceleration. The general formula of Moment of Inertia is given by -

I = Σ m[i] r[i]².

According to the question -

Mass of skater = 58 Kg

Radius = 0.102 m

Now, the moment of inertia of the cylinder about the axis of cylinder is -

I = 1/2 MR²

I = 0.5 x 58 x 58 x 0.102 x 0.102

I = 1682 x 0.010404

I = 0.301 kg m²

Hence, the Moment of Inertia of skater of mass 58 Kg with  approximated radius of 0.102 m will be 0.301 kg m².

A metal bowl with a weight of 1.05 n is placed in a larger kitchen container filled with soybean oil. how much soybean oil must the bowl displace in order to float? for reference, the mass density of soybean oil is about 917 g/liter and its weight density is about 8,99 n/liter. please give your answer in liters

Answers

The volume of soybean oil displaced by the boat to float is 0.00011 liters or 1.1 x 10^-4 liters.

An object floating in a liquid follows Archimedes’ Principle.

According to the Archimedes Principle, the amount of fluid displaced by the body is equal to its weight.

So, the buoyant force applied by the liquid should be equal to the weight of the bowl.

Hence

Weight of bowl = Buoyant Force of Soybean Oil

Mg = V(ρ)(g)

Here V = volume of soybean oil

ρ = density of soybean oil

1.05 = V x 917 x 9.8

The volume(V) comes out to be 0.00011 liters.

The induced electromotive force (emf) with different polarities induces a current whose magnetic field opposes the change in magnetic flux through the loop in to ensure that the original flux is maintained throughout the loop when the current flows in it.

How is Lenz’s law conservation of energy?

Lenz’s law is based on the law of conservation of energy. The induced current is always opposed by the cause that produces it. Hence, there is extra work done against the opposing force. The work done against the opposing force results in the change in the magnetic flux and hence the current is induced. Hence the law of conservation of energy is satisfied.

The main interaction in ionic compounds is ionic bonding, a type of chemical bonding that involves the electrostatic attraction between two atoms or ions with dramatically differing electronegativities.

When a metal and a non-metal react, an ionic bond is created.

s = ut  + 1/2 g[tex]t^{2}[/tex]

By putting the value of h and t in the  equation

1.50 = u × 0.240 + 1/2 × 9.8 × [tex]0.240^{2}[/tex]

u = (1.50 - 0.28224) / 0.240

u=  5.074

Newton’s second law relates an object’s acceleration to its mass and the net force acting on it. Does newton’s second law apply to a situation in which there is no net force? select the best explanation.

Answers

Newton's second law does apply to a situation in which there is no net force as having a net force of zero will produce an acceleration having 0.  

According to Newton's second law, the acceleration of an object depends upon two variables- the mass of the object and the net force acting on the object. Here, the acceleration of an object is directly proportional to the force acting on it and inversely proportional to the mass of that object. The net force applied is equal to the sum of all the forces acting on an object.

In a situation where the net force applied is zero, the object having a mass would have zero acceleration. This means that the object would have zero velocity and would be constant.

This depicts that Newton's second law can be applied to every situation where there is a net force applied, or not. Even if there is no net force, this law can still be applied.

What is force ?

In physics, a force is a power that could exchange the motion of an item. A force can reason an item with mass to alternate its velocity (e.g. moving from a kingdom of relaxation), i.e., to accelerate. force also can be described intuitively as a push or a pull. A pressure has each significance and course, making it a vector amount. it's far measured within the SI unit of newton (N). force is represented by the symbol F (formerly P).

The original form of Newton's second regulation states that the net pressure acting upon an object is same to the price at which its momentum adjustments with time. If the mass of the item is consistent, this regulation means that the acceleration of an item is without delay proportional to the internet pressure performing on the item, is in the route of the net force, and is inversely proportional to the mass of the item.

principles associated with pressure include: thrust, which will increase the velocity of an item; drag, which decreases the velocity of an item; and torque, which produces changes in rotational velocity of an item.
