An object that is initially at rest on a frictionless floor is struck by a flying rock with an impulse jfonox. what is the final

momentum of the object?

Answer:

jfonox

Explanation:

since impulse is the change in momentum given by

Impulse = Force x time = change in momentum

I = ft = mv-mu= m(v-u)= jfonox

since the object is initially at rest

u=0,

mv is the final momentum of the object

I =Ft = m(v - 0) = jfonox

mv= jfonox

this show that the final momentum of the object at rest is equal to the impulse received

if  any of the mass m, final velocity v or the impact force and the duration of impact of the object is known then we can find or quantify the final momentum.

Please help!! This is the last question and i’m unsure! I will mark brainliest! Please try to provide a explanation you don’t ha
Flauer [41]

Answer:

True

Explanation:

As of Newton's law, yes. Because when I land my feet on the ground, I apply a force. As per Newton's third law, the ground must apply the same force on me.

If its correct, may I hv brainliest?

Select the statements that apply in order to complete the model (you can choose multiple answers).
Mashutka [201]

The statement a,d and e are correct. The chemical equation must be balanced.

<h3>What is a chemical reaction ?</h3>

One or more compounds, known as reactants, are transformed into one or more distinct substances, known as products. Such a process is known as a chemical reaction.

The given equation is;

\rm  CH_4+2O_2 \arrow \rightarrow CO_2+2H_2O

The statements that apply in order to complete the model is;

a) The products must equal the reactants.

d) One carbon atom and two oxygen atoms are needed to balance the equation.

e) One carbon dioxide molecule should be added to the product side of the equation.

Hence, statement a,d and e are correct.

To learn more about the chemical reaction, refer to the link;

Which of the following is a characteristic of the cosmic microwave background radiation
Akimi4 [234]

Answer:

The Cosmic Microwave Background radiation, or CMB for short, is a faint glow of light that fills the universe, falling on Earth from every direction with nearly uniform intensity. It is the residual heat of creation--the afterglow of the big bang--streaming through space these last 14 billion years like the heat from a sun-warmed rock, reradiated at night.

Since the early twentieth century, two concepts have transformed the way astronomers think about observing the universe. The first is that it is fantastically large; the portion of the universe visible today is a sphere nearly 15 billion light-years in radius, and that, we believe, is just the tip of the iceberg. The second is that light travels at a fixed speed. A simple consequence of these ideas is that as you look at more and more distant objects, you're seeing farther and farther back in time--sometimes very far back indeed. When you see Jupiter shining in the night sky, for example, you're looking about an hour back in time, whereas the light from distant galaxies captured by telescopes today was emitted millions of years ag0.
