Answer: p = mv

Explanation:  momentum(p) is equal to mass(m) and velocity(v).

Answer:

Dynamic Equilibrium are stable because there is an equal rate of transition between reactants and products, or between the forward and the reverse process, in a back and forth manner, such that the net change of the concentration or system is zero, and therefore, there are no excess force factor, tending to create a different outcome

Explanation:

Dynamic equilibrium, in physics and in chemistry, is the equilibrium experienced by a system that undergoes change, where however, both the forward and the reverse effect of the change are taking place.

Answer:

57 N

Explanation:

Were are told that the force

of gravity on Tomas is 57 N.

And it acts at an inclined angle of 65°

Thus;

The vertical component of the velocity is; F_y = 57 sin 65

While the horizontal component is;

F_x = 57 cos 65

Thus;

F_y = 51.66 N

F_x = 24.09 N

The net force will be;

F_net = √((F_y)² + (F_x)²)

F_net = √(51.66² + 24.09²)

F_net = √3249.0837

F_net = 57 N

Answer:

C

Explanation:

Option C - Its displacement in a given period of time is the correct alternative.

We have the velocity of an object.

We have to find out what other quantity is needed to determine the velocity.

Velocity is defines as the rate of change of displacement with time. Mathematically -

v = Δx/Δt

According to the question -

As discussed above, velocity is the ratio of displacement and time taken to cover that displacement. Velocity is the measure of how fast a specific object is moving. Lesser the time taken to cover the distance, faster is the object as -

F [tex]\alpha[/tex] 1 / t

Acceleration, weight and mass of the object has nothing to correlate with the velocity of object at any specific location since mass and weight will remain constant throughout.  Therefore it is displacement in given period of time that is required.

Hence, Option C is the correct alternative.

Explanation:

The Sun's gravitational pull helps to control tides on earth and also to keep the earth in a curvilinear motion.

Gravity, or gravitation, is a natural phenomenon in which all entities with mass or energy are drawn to one another, including planets, stars, galaxies, and even light.

The gravitational pull of the sun continuously pulls the earth towards it, although because of the fast movement of the earth we never reach towards the sun instead we revolve around it.

Despite the fact that the sun's gravitational pull is neutralised by the movement of the earth in a curve, there is still some gravitational pull that exists which helps to control the tides on earth.

Thus, the Sun's gravitational pull helps to control tides on earth and also to keep the earth in a curvilinear motion.

Answer:

Sexual Dimorphism of the Human Skeleton. The human skeleton is not as sexually dimorphic as that of many other primate species, although human female skeletons tend to be smaller and less robust than human male skeletons within a given population. There are also subtle differences between males and females in the morphology of the skull, teeth, longs bones, and pelvis.

1. Which limiting factor(s) in this lab simulation are biotic?

The limiting factors in this lab that are biotic are predators and food.  

2. Which limiting factor(s) in this lab simulation are abiotic?

The limiting factor in this lab that is abiotic is pollution.  

3. Which limiting factor impacted the cricket frog population the most? Use evidence to support your answer.

The limiting factor that impacted the cricket frog population the most is the predators because the population went to 90K and then all the way down to 15K.

4. Which limiting factor impacted the cricket frog population the least? Use evidence to support your answer.

The limiting factor that impacted the cricket frog population the least is pollution because it stayed the same then went down to 35K.

5. Mosquitoes can carry and transmit disease to animals and humans. Explain how the cricket frog plays an important role in limiting the spread of mosquito-borne illnesses like West Nile virus and malaria.

The cricket frogs play an important role in limiting the spread of mosquito borne illnesses because they consume the mosquitos and decrease the population of contaminated mosquitos.  

6. Predict the long-term effects of these limiting factors on the cricket frog population in the pond ecosystem.

Eventually the cricket frog population may die out because of all the negative factors. If there are too many mosquitoes, then the frog population can begin to die out. With pollution, the frogs do not have a safe and clean environment to leave in and can get infected, sick, and can die after a while. Crocodiles need to eat, so they are also bringing down the population.

Answer:

conductor

Explanation:

A "conductor" is a material that allows the charges to pass freely from one body to the other. This causes a movement among the electrons and this means that the charge will be passed entirely to the object receiving it. This is also called "conductive material."

Examples of conductors are: copper, aluminum, gold, silver, seawater, etc.

The opposite of conductors are called "insulators." These do not allow the free movement of charges from one object to the other.

Examples of insulators: plastic, rubber, paper, glass, wool, dry air, etc.

The y-component of the ball's velocity is 10 m/s

The second choice 10.0 m/s is correct

Explanation:

Projectile Motion

It's the type of motion that experiences an object that is projected near the Earth's surface and moves along a curved path exclusively under the action of gravity.

Being vo the magnitude of the initial velocity and θ the angle it makes with the horizontal, the components of the initial velocity are calculated as follows:

[tex]v_{ox}=v_o.\cos\theta[/tex]

[tex]v_{oy}=v_o.\sin\theta[/tex]

Since the football is kicked at vo=20 m/s and an angle of θ=30°:

[tex]v_{oy}=20.\sin 30^\circ[/tex]

[tex]v_{oy}=20*0.5=10[/tex]

The y-component of the ball's velocity is 10 m/s

The second choice 10.0 m/s is correct

Explanation:

Answer:

The air around you has weight, and it presses against everything it touches. That pressure is called atmospheric pressure, or air pressure. It is the force exerted on a surface by the air above it as gravity pulls it to Earth.

Atmospheric pressure is commonly measured with a barometer. In a barometer, a column of mercury in a glass tube rises or falls as the weight of the atmosphere changes. Meteorologists describe the atmospheric pressure by how high the mercury rises.

An atmosphere (atm) is a unit of measurement equal to the average air pressure at sea level at a temperature of 15 degrees Celsius (59 degrees Fahrenheit). One atmosphere is 1,013 millibars, or 760 millimeters (29.92 inches) of mercury.

Atmospheric pressure drops as altitude increases. The atmospheric pressure on Denali, Alaska, is about half that of Honolulu, Hawai'i. Honolulu is a city at sea level. Denali, also known as Mount McKinley, is the highest peak in North America.

Answer:

The acceleration of the ball is constant and equal to -9.81 m/s² (acting downwards)

The velocity of the ball reduces at a constant rate with time on its way up

Explanation:

The motion of the ball upwards is described by the following equation;

v = u - g × t

v² = u² - 2 × g × s

Where;

v = The final velocity of the ball

u = The initial velocity of the ball

g = The acceleration due to gravity = Constant

s = The height of the bass after a given time, t

t = The time in which the ball is rising

Therefore, the acceleration of the ball = The acceleration due to gravity  (Constant) = -9.81 m/s²↓

From v = u - g × t = u - 9.81 × t , the velocity of the ball reduces at a constant rate with time on its way up.

Answer:

Acceleration remains constant and velocity decreases

A chemical symbol is a one- or two-letter designation of an element. Compounds are combinations of two or more elements. A chemical formula is an expression that shows the elements in a compound and the relative proportions of those elements. Many elements have symbols that derive from the Latin name for the element.

Answer: Approximately 302 m/s^2

================================================

Work Shown:

s = starting velocity = 0

f = final velocity  = 46

d = distance = 3.5

a = acceleration = unknown (we're solving for this)

[tex]f^2 = s^2 + 2a*d \ \ \text{ ..... one of the kinematics equations}\\\\46^2 = 0^2 + 2a*3.5\\\\2116 = 7a\\\\7a = 2116\\\\a = \frac{2116}{7}\\\\a \approx 302.28571\\\\a \approx 302[/tex]

The acceleration to three sig figs is roughly 302 m/s^2

The acceleration is so large because the ball's final velocity is incredibly fast in such a short amount of time.

Answer:

25 m/s

Explanation:

Momentum = mass × velocity

Given that,

velocity  = Momentum ÷ mass

velocity = 1800 ÷ 72
