Answer:

Alarm Clock. The buzzing sound of an alarm clock helps you wake up in the morning as per your schedule. The sound is something that you can’t see, but hear or experience.
Cell Phones Cellphones have become like Oxygen gas in modern social life. Hardly, anyone would have been untouched by the effects of a cell phone. Whether conveying any urgent message or doing incessant gossips, cellphones are everywhere. But do you know how does a cell phone work? It works on the principle of electricity and the electromagnetic spectrum, undulating patterns of electricity and magnetism.
Walking.Now, when you get ready for your office/school, whatever medium of commutation is, you certainly have to walk up to a certain distance. You can easily walk is just because of Physics. While you have a walk in a park or on a tar road, you have a good grip without slipping because of a sort of roughness or resistance between the soles of your shoes and the surface of the road.

Explanation:

physical is related to things perceived through the senses as opposed to the mind; tangible or concrete.

Two carts, one of mass 2m and one of mass m, approach each other with the same speed, v. When the carts collide, they

Svetradugi [14.3K]

Answer: Graph C is the correct option

Explanation:

The question is incomplete, please remember to submit the whole question :)

However, the rest of the question with its corresponding figures is below:

Assume that positive momentum is to the right, which of the following best represents the momentum of the cart of mass m as a function of time before and after the collision?

The initial momentum $p_{o}$ of the cart with mass $m$ (before the collision) is:

$p_{o}=-mV$ (1) Note the negative sign indicates the direction of cart's velocity (to the left, as seen in the first image attached)

On the other hand, the final momentum $p_{f}$ of both carts (after the inelastic collision) is:

$p_{f}=(2m+m) V_{f}=3m V_{f}$ (2)

So, according to this, the correct graph tha best represents the situation is C. Since before the collision the momentum is negative, then both carts slow down after the collision ( $V_{f}$ ), and taking into account the linear momentum is directly proportional to the velocity $p_{f}$ (although is in the positive direction) is less than $p_{o}$ .

What is the gravitational force between mars and Phobos

alina1380 [7]

Answer:

$F=5.16\times 10^{15}\ N$

Explanation:

We have,

Mass of Mars is, $m_M=6.42\times 10^{23}\ kg$

Mass of its moon Phobos, $m_P=1.06\times 10^{16}\ kg$

Distance between Mars and Phobos, d = 9378 km

It is required to find the gravitational force between Mars and Phobos. The force between two masses is given by

$F=G\dfrac{m_Mm_P}{d^2}$

Plugging all values, we get :

$F=6.67\times 10^{-11}\times \dfrac{6.42\times 10^{23}\times 1.06\times 10^{16}}{(9378\times 10^3)^2}\\\\F=5.16\times 10^{15}\ N$

So, the gravitational force is $5.16\times 10^{15}\ N$ .

What did James Madison foresee as an important element of the political system?

Papessa [141]

An important element of the political system as foreseen by James Madison is Interest groups.

Option c

<h3><u>Explanation:</u></h3>

The group of people with specific political interest is known as political interest group. Many efforts are organized to influence laws and policies of government. These political groups pass laws which benefits their own political group. This group can also be known as special interest group or advocacy groups.

The main purpose of Interest group is to influence public group. The work done by them is to educate the public and also policy makers and their issues. Many ways to fund their causes is also found. The function of interest group is to influence the policy of public in its favor.

Answer:

The height is : 60.025 m

Explanation:

The flowerpot falls off the balcony with zero launch angle

Given the time of fright as 3.5 s then ;

The formula to apply is ;

$T=\sqrt{\frac{2H}{g} }\\\\3.5=\sqrt{\frac{2H}{9.8} }$

3.5²= 2H/9.8

12.25 =2H/9.8

12.25 * 9.8 = 2H

120.05 = 2H

120.05/2 = H

60.025 =H
