An increase in which quantity will result in an increase in momentum?

Answers

Answer 1

Answer: Momentum = (mass) x (velocity)

(Remember that momentum is a vector ... it has a direction.
Its direction is the same as the velocity.)

An increase in either mass or velocity will increase the momentum.

It's pretty hard to increase the mass of a moving object, so I think
the better answer is velocity .

Two objects are moving at equal speed along a level, frictionless surface. the second object has twice the mass of the first object. they both slide up the same frictionless incline plane. which object rises to a greater height?

Answers

Answer:

They both rises to same height.

Explanation:

When an object is sliding up in friction less surface than according to conservation of energy its potential energy will be converted into kinetic energy.

$mgH=(1)/(2)mv^(2)\n v=√(2gH)$

Here, m is the mass, v is the velocity, g is the acceleration due to gravity and H is the height.

Here the height is independent on the mass of an object and its only depend on velocity.

Now according to the question, two objects have same velocity but they have different masses.

Therefore, they rises to the same height because height will not change with mass.

Both objects rise to the same height

$\texttt{ }$

Further explanation

Let's recall Kinetic Energy Formula as follows:

$\large {\boxed{Ek = (1)/(2)mv^2} }$

Ek = Kinetic Energy ( Joule )

m = mass of the object ( kg )

v = speed of the object ( m/s )

Let us now tackle the problem !

$\texttt{ }$

Given:

initial speed of first object = initial speed of second object = v

final speed of first object = final speed of second object = 0

mass of first object = m

mass of second object = 2m

Asked:

height = H = ?

Solution:

We will use Conservation of Energy to solve this problem:

$Ep_1 + Ek_1 = Ep_2 + Ek_2$

$0 + (1)/(2)mv^2 = mgH + 0$

$(1)/(2)v^2 = gH$

$v^2 = 2gH$

$\boxed {H = (v^2)/(2g)}$

$\texttt{ }$

$H_1 : H_2 = (v_1^2)/(2g) : (v_2^2)/(2g)$

$H_1 : H_2 = v_1^2 : v_2^2$

$H_1 : H_2 = v^2 : v^2$

$H_1 : H_2 = 1 : 1$

$\boxed{ H_1 = H_2 }$

$\texttt{ }$

Conclusion:

Both objects rise to the same height

Human impacts on biomes are best characterized by _______

Answers

Answer;

-Interruption of natural biome processes

Explanation;

-Human beings have continuously continued with interference of different biomes and thus bringing various modifications to these biomes. Human activities often affect ecosystems in negative ways because human systems are not closed loop systems. For example; human waste enters other natural ecosystems, where it can cause them to become unbalanced

-If efforts are not enhanced in conserving the natural world, we shall continue experiencing deteriorating weather factors like the global warming. Failure to conserve our biosphere will ultimately hurt the human race, together with organisms in various biomes.

Final answer:

Human impacts on biomes include changes in biodiversity, alterations in ecosystem structure, and climate change. These impacts stem from human activities like deforestation, mining, pollution and the emission of greenhouse gases.

Explanation:

Human impacts on biomes are best characterized by changes in biodiversity, alterations in ecosystem structure, and climate change. The significant increase in human population and activities such as deforestation, mining, and pollution lead to biodiversity loss and habitat destruction. These activities collectively trigger alterations in the ecosystem structure. Additionally, human-induced emissions of greenhouse gases contribute to global climate change, which further disturbs the biomes - the various life zones on Earth. Therefore, the major human impacts on biomes include changes in biodiversity, ecosystem structure alterations, and climate change.

When you look at green dots with a red filter what color did you see?

Answers

-- Looking at the dots casually, they look green because they absorb all other
colors of light, and only green light is left to proceed to your eyes. (In order for
this to work, there has to be some green in the light shining on the dots.
Daylight and most light bulbs work fine.)

-- The filter looks red because it absorbs all other colors of light, and only
the red light is left to pass through the filter and come out on the other side.

-- When the green light from the dots hits the red filter, it's absorbed in the
filter, and there's no light left to come out on the other side.

If you're looking through the filter at the dots, they look black.

A 10.-kilogram object, starting from rest, slides down a frictionless incline with a constant acceleration of 2.0 m/sec2 for four seconds. What is the approximate weight of the object? A) 1 N B) 10 N C) 100 N D) 1,000 N

Answers

C) 100N

Given:

Mass of the object = 10kg

Acceleration due to gravity = 9.81m/s²

Weight is a measure of the force of gravity pulling down on an object. It depends on the object's mass and the acceleration due to gravity, which is 9.8 m/s² on Earth.

Formula for calculating the Weight of an object is expressed as;

Weight = mass × acceleration due to gravity

On substituting the values in the above formula:

Weight = 10×9.81

Weight = 98.1N

Hence, the approximate weight of the object is 100N.

Therefore, the correct option is option C.

What type of energy is involved when a river moves sediment and erodes its banks?a. chemical energy

What happens as gravity pulls water down a slope?
a. Kinetic energy changes to potential energy.
b. Both kinetic and potential energy vanish.
c. Energy is stored for future use.
d. Potential energy changes to kinetic energy.

Answers

First question: The type of energy involved when a river moves sediment and erodes its banks is: option d. Kinetic energy. Kinetic energy is the energy associated with motion. A body (in this case the water) that moves has an energy associated with its motion that is proportional to the speed (exactly to the square of the speed). When the water collides with the banks it is the kinetic energy of the river that erodes it Second question: the answer is the option d. As gravity pulls water down a slope potential energy changes to knietic energy. This is the, water loses altitude and gains velocity. The potential energy. which is proportional to the height, decreases and the kinetic energy, which is proportional to the square of the speed, increases.

Answer:

Question A: D., or "kinetic energy".

Question B: D., or "Potential Energy changes to kinetic energy."
