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;
P is the pressure applied to the blockA is the area of the rock h is the depth in which the rock is subjected to g is acceleration due to gravityThus, 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.

Which has more kinetic
energy, a bowling ball or
a baseball rolling on a
table at the same speed?
Why?
Answer: a bowling ball
Explanation: a baseball doesn’t need as much kinetic energy because it’s smaller
If a bowling ball is rolling at the same speed as a small baseball then since the bowling ball is bigger it has more kinetic energy

what is the smallest possible value for the index of refraction?
Answer:
1.0
Explanation:
The smallest possible value for the index of refraction is 1.0.
What is Index of refraction?This talks about how fast light travels through an object by taking note of how much the light is bent, or refracted, as it enters into the material.
The smallest possible value for the index of refraction is 1.0 because the speed of light in any medium is always less than than the speed of light in air or vacuum.

an astronaut on an eva has wandered dangerously far away from the shuttle. she has also exhausted all the fuel in her jet pack. how can she get back to the shuttle?
The conservation of the momentum allows to find the result of how the astronaut can return to the spacecraft is:
Throwing the thruster away from the ship.
The momentum is defined as the product of the mass and the velocity of the body, for isolated systems the momentum is conserved. If we define the system as consisting of the astronaut and the evo propellant, this system is isolated and the internal forces become zero. Let's find the moment in two moments.
Initial instant. Astronaut and thrust together.
p₀ = 0
Final moment. The astronaut now the thruster in the opposite direction of the ship.
[tex]m_f[/tex] = m v + M v '
where m is propellant mass and M the astronaut mass.
As the moment is preserved.
0 = m v + M v ’
v ’= [tex]- \frac{m}{M} \ v[/tex]
We can see that the astronaut's speed is in the opposite direction to the propeller, that is, in the direction of the ship.
The magnitude of the velocity is given by the relationship between the masses.
In conclusion, using the conservation of the momentun we can find the result of how the astronaut can return to the ship is:
Throwing the thruster away from the ship.

The horizontal surface on which the block of mass 2.2 kg slides is frictionless. The force of 27 N acts on the block in a horizontal direction and the force of 81 N acts on the block at an angle as shown below is the magnitude of the resulting ac celeration of the block? The acceleration of gravity is 9.8 m/s ^ 2
The magnitude of the resulting acceleration of the block is 6.14 m/s².
The given parameters;
mass of the block, m = 2.2 kghorizontal force on the block, F = 27 Nforce below the horizontal, 81 N at 60⁰The net horizontal force on the block is calculated as follows;
[tex]F_x = 27 \ - 81 \times cos (60)\\\\F_x = -13.5 \ N[/tex]
The acceleration of the block is calculated as follows;
[tex]a = \frac{-13.5}{2.2} \\\\a = - 6.14 \ m/s^2\\\\a = 6.14 \ m/s^2 \ to \ the \ left[/tex]

An aircraft traveling at 600km/h accelerates steadily at 10km/h per second. Taking the speed of sounds as 1100km/h at the aircraft's altitude, how long will it take to reach the sound barrier.
Answer:
V2 - V1 = a t for uniformly accelerated motion
t = (V2 - V1) / a = (1100 -600) km/hr / 10 km/hr/sec
t = 500 / 10 sec = 50 sec

a dog is running at 5.5 m/s then comes to a complete stop in 1.5 seconds. What is the dogs acceleration?
The dog's acceleration running at 5.5 m/s then comes to a complete stop in 1.5 seconds is 8.25m/s²
HOW TO CALCULATE ACCELERATION:
The acceleration of a moving object can be calculated by multiplying the velocity of the object by the time taken. That is;Acceleration (m/s²) = speed (m/s) × time (s)According to this question, a dog is running at 5.5 m/s then comes to a complete stop in 1.5 seconds. The acceleration can be calculated as follows:Acceleration = 5.5 × 1.5Acceleration = 8.25m/s²Therefore, the dog's acceleration running at 5.5 m/s then comes to a complete stop in 1.5 seconds is 8.25m/s².Learn more at: https://brainly.com/question/19573976?referrer=searchResults

Determine your mass in kg noting that 1 kg is about 2.2 lbs. Then use Fg = mg to find your weight in Newtons.
Answer: see example due to variation of factor
Explanation: w = m x g
Weight= Mass (in kg) x Gravity (9.8m/s)
To get to kg from lbs take your weight divide by 2.2lbs well get you to kg
Example
Let's say a boy weighs 145lbs
145kg/2.2lbs=66kg
Now we use the equation
w=m x g
65kg*9.81m/s=637.65N

Explanation:
The 10N of force acting down and up on the object cancel out.
The 15N of force pulling the force to the right is stronger than the 5N of force pulling the object left
15N - 5N = 10N
The magnitude and unit is 10N, and the direction is right
