The rock will compress as the stress applied increases with depth and it will break when it cannot withstand the stress.

The pressure or stress on the rock is defined as force per unit area of the rock which equally increases with depth. This can be expressed as follows;

[tex]P= \frac{F}{A}\\\\P = \rho gh[/tex]

where;

Thus, we can conclude that the stress on the rock will increase with increase in depth. The rock will compress as the stress applied increases with depth and it will break when it cannot withstand the stress.

Answer:

17.64 Newtons

Explanation:

In order to find the weight of an object we take the mass in kilograms and multiply it by the gravitational constant (9.8), which is 1.8 * 9.8 = 17.74 Newtons.

Weight is force on the body of given mass 1.8 Kg. Weight is 17.64 N.

A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

Weight of body is force due to gravity,

F = mg

F = 1.8*9.8

F = 17.64 N

Weight of the body is given as 17.64 N.

Weight is force on the body of given mass 1.8 Kg. Weight is 17.64 N.

Answer:

It shows the same number of atoms of each element on both sides of the equation

A balanced equation demonstrates the conservation of mass by having the same number of each type of atom on both sides of the arrow.

Explanation:

Matter cannot be created or destroyed in chemical reactions. This is the law of conservation of mass. In every chemical reaction, the same mass of matter must end up in the products as started in the reactants. Balanced chemical equations show that mass is conserved in chemical reactions.

A balanced chemical equation shows that total number of atoms before reaction is equal to total number of atoms after the reaction. As, the total mass of any object lies on its atom, a balanced chemical equation demonstrate the Law of Conservation of Mass.

The Dalton's atomic theory is as follows:

The total number of atoms before and after a reaction are equal, according to a chemical equation that is in balance. A balanced chemical equation illustrates the Law of Conservation of Mass since every object's atom holds the entirety of its mass.

This question involves the concepts of the equations of motion for both the vertical motion and the horizontal motion.

The diver "does not" hit the rock.

First, we will calculate the time taken by the diver to land. For this purpose, we will use the second equation of motion for the vertical motion of the diver:

[tex]h = v_{iy}t+\frac{1}{2}gt^2[/tex]

where,

h = height of cliff = 44 m

[tex]v_{iy}[/tex] = vertical component of the initial velocity of the diver = 0 m/s

t = time taken to land = ?

g = acceleration due to gravity = 9.81 m/s²

Therefore,

[tex]44\ m=(0\ m/s)t+\frac{1}{2}(9.81\ m/s^2)(t)^2\\\\t = \sqrt{\frac{(44\ m)(2)}{9.81\ m/s^2}}[/tex]

t = 3 s

Now, we will calculate the horizontal distance where the diver landed. For this purpose, we will use the equation of motion for the horizontal motion of the diver. Assuming the air resistance to be zero the horizontal motion will be uniform. Hence:

[tex]s = vt\\s = (1.8\ m/s)(3\ s)\\[/tex]

s = 5.4 m

Since the section of the rock was 4 m away from the cliff. Hence, the diver crossed that rock section and safely laded at a distance of 5.4 m, which is 1.4 m ahead of the rock section.

Answer:

i think firest one is true

and the second one is D

Answer:

the velocity is 4 ms, if it asked for change it be 0 m/s but its asking for velocity so option 4, 4m/s

Explanation:

The correct answer is Option 2: 2 m/s². The acceleration of the object at 8 seconds is 2 m/s². Note that the negative sign indicates that the acceleration is in the opposite direction of the velocity.

To calculate the acceleration of the object at 8 seconds, we need to look at the change in velocity over time (acceleration is the rate of change of velocity).

Given the graph, we can see that at 8 seconds, the velocity of the object is 6 m/s.

Now, let's find the change in velocity between 8 seconds and 10 seconds:

Change in velocity = Final velocity - Initial velocity

Change in velocity = 2 m/s - 6 m/s

Change in velocity = -4 m/s

Next, find the time interval between 8 seconds and 10 seconds:

Time interval = Final time - Initial time

Time interval = 10 s - 8 s

Time interval = 2 seconds

Now, calculate the acceleration:

Acceleration = Change in velocity / Time interval

Acceleration = (-4 m/s) / (2 s)

Acceleration = -2 m/s²

The correct answer is Option 2: 2 m/s². The acceleration of the object at 8 seconds is 2 m/s². Note that the negative sign indicates that the acceleration is in the opposite direction of the velocity.

Due to paralysis, the result is severe spinal injuries. This is often the case because the spine houses much of the central nervous system, which controls movement. Hence, option C is correct.

You might become paralyzed, and unable to move on your own when something interferes with the nerve impulses that muscles receive from the brain. Strokes, spinal cord injuries, and neurological diseases like multiple sclerosis are among the common causes of paralysis.

When you are unable to move your muscles voluntarily, you are said to be paralyzed. Paralysis results from nerve system issues.

Muscles receive messages from healthy nerves. This causes the muscles to contract. When you’re paralyzed, or have paralysis, you can’t move certain parts of your body.

The force is different because of the amount of weight applied so the answer is A

The force that makes a difference in the weight of each person is Gravitational. Correct option is B.

Gravitational force is a fundamental force of nature that exists between any two objects with mass. It's the force that keeps us and everything else on Earth anchored to its surface. This force is proportional to the mass of the objects involved and inversely proportional to the square of the distance between them.

For example, if you were standing on a bathroom scale, the reading on the scale represents the force of the Earth's gravity acting on your body, which is why it's often referred to as your "weight." The actual mass of an object remains constant regardless of its location, but its weight can vary depending on the strength of the gravitational field at different locations (e.g., the weight on the Moon would be less than on Earth due to the Moon's weaker gravitational pull).
