how would you describe gravity?

Answer:

4

Explanation:

Not all plants can grow flowers. Only the ones thay have buds can.

Not all plants produce flowers. Hence, this is the characteristic which is not common in all plants.Therefore, the correct option is 4.

Flowers are the structures of plants. They are responsible for producing seeds that will grow into new plants. Flowers typically consist of a colorful or ornamental part called the corolla, which attracts pollinators such as bees and butterflies, and a reproductive part called the stamen and pistil, which contain the plant's male and female organs.

Not all green plants produce flowers. Flowering plants are a type of plant that belong to the group Angiosperms, but there are also non-flowering plants like ferns and mosses that do not produce flowers. Therefore, the correct option is 4.

Answer:

q = 0.384 C

Explanation:

The total charge present at the head can be easily found out by multiplying the charge on a single electron with the total number of electrons present on the head:

[tex]q = ne[/tex]

where,

q = total charge on head = ?

n = total no. of electrons on the head = 2.4 x 10¹⁸

e = charge on 1 electron = 1.6 x 10⁻¹⁹ C

Therefore,

[tex]q = (2.4\ x\ 10^{18})(1.6\ x\ 10^{-19}\ C)[/tex]

q = 0.384 C

Answer:

he would have to run at a 7 and a half mile to get 8 miles in an hour

Explanation:

Answer:

7.5 minutes

Explanation:

We know that there are 60 minutes in an hour. So, we can say that Rogan can run 8 miles per 60 minutes. Now, we can create an equation to solve for how many minutes it would take per mile.

8/60 = 1/x

x = 7.5

So, it would take Rogan approximately 7.5 minutes to travel 1 mile.

Answer:

here's the link you asked for: https://www.nyas.org/ebriefings/the-physics-of-everything/ and here's the info inside the link: During the second quarter of 2016, the Academy hosted a series of evening panel discussions boldly titled "." With grant support from The John Templeton Foundation, the six panels addressed how physics is addressing grand questions and the potential limitations on what we may be able to learn using physics to address those questions.

The first session posed the question "" Three physicists explored the frontiers of cosmology and quantum physics. There may always be limits to our understanding in areas such as string theory, dark matter, and multiverses. But the panelists agreed that it is best to proceed as if explanations based in physics can be found.

The second session asked "" The panelists argued that philosophy has much to offer physics, in contrast to the assertions of some prominent physicists. In such areas as the role of observations in quantum mechanics and the experimental validation of theory, the panelists illustrated the power of a critical, interdisciplinary approach to understanding not only the facts but the significance of physics ideas.

Physics has achieved its success in part by selecting problems that can be addressed by reducing them to simple parts following simple laws. Less amenable subjects were discussed in the third session, "" Biology, ecology, and social phenomena such as cities are all not easily described with simple equations, but still show amazing regularities. The panelists, including two physicists, a philosopher, and a computer scientist, sketched their hopes for unifying principles that explain these regularities.

One complex phenomenon that has so far evaded physical analysis was the topic of the fourth session, "." Two of the panelists, a neuroscientist and a roboticist, did not even regard consciousness as a distinct phenomenon but rather as a byproduct of systems that model themselves. In contrast, a philosopher and a physicist felt that this behavioral description misses something essential about what consciousness "feels like." Both groups expressed hope for experimental tests of their views.

The fifth session addressed the question, "" Recent experimental observations of thousands of planets orbiting other stars bolster the expectation that ours is not the first civilization. The panelists explored how we might look for others and why we have not encountered any yet. One troubling possibility is that civilizations that achieve global scale inevitably encounter challenges such as climate change that they fail to overcome.

The sixth session was entitled "." Two physicists and a computer scientist discussed amazing developments at the intersection of quantum gravity (as manifested in black holes) and quantum information. Trying to reconcile these disparate observations has overturned the traditional view of black holes, with no clear resolution so far. At the same time, an abstract connection between gravitational models and quantum models in one fewer dimension is providing insight into both fields, including new methods for error correction in quantum computing as well as benchtop tests of black hole physics.

The wide ranging discussions of the six panels illustrate the power of physics to explain the universe as well as the vast frontiers of that universe that still remain to be explored.

you tend to push off with the foot still on the boat.

Newtons 3rd law of motion hold that every action has an equal and opposite reaction.

So, the amount of force you use on your back foot to push yourself onto the dock, has an equal end opposite amount of force going the other way from your sole of your foot, which pushes the boat the other way.

The speed of the penny drops of a bridge just before it hits the water is 11.76 ms⁻¹.

Given,

Time, t = 1.2 s

The initial velocity (u), final velocity (v), acceleration (a), displacement (s), and time (t) of an object traveling with constant acceleration are related by the first equation of motion, often known as the first kinematic equation or the equation of motion with constant acceleration.

From the first equation of motion:

v = u + at

Since the initial velocity is zero. The final velocity is:

v = at

v = (9.8 ) × (1.2 s)

v = 11.76 ms⁻¹

Hence, the speed of the penny drops of a bridge just before it hits the water is 11.76 ms⁻¹.

Answer:

a) The work done by the force is 720 joules, b) The power supplied by the force is 138 watts.

Explanation:

a) Since force is uniform and parallel to the direction of motion, the work ([tex]W[/tex]), in joules, done by the force ([tex]F[/tex]), in newtons, is defined by this formula:

[tex]W = F\cdot s[/tex] (1)

Where [tex]s[/tex] is the travelled distance, in meters.

If we know that [tex]F = 60\,N[/tex] and [tex]s = 12\,m[/tex], then the work done by the force is:

[tex]W = F\cdot s[/tex]

[tex]W = (60\,N)\cdot (12\,m)[/tex]

[tex]W = 720\,J[/tex]

The work done by the force is 720 joules.

b) And an expression for the power supplied by the force ([tex]\dot W[/tex]), in watts, is concieved by differentiating (1) in time:

[tex]\dot W = F\cdot \dot s[/tex]

Where [tex]\dot s[/tex] is the speed of the wagon, in meters per second.

If we know that [tex]F = 60\,N[/tex] and [tex]\dot s = 2.3\,\frac{m}{s}[/tex], then the power supplied by the force is:

[tex]\dot W = F\cdot \dot s[/tex]

[tex]\dot W = (60\,N)\cdot \left(2.3\,\frac{m}{s} \right)[/tex]

[tex]\dot W = 138\,W[/tex]

The power supplied by the force is 138 watts.

New force = 9(initial force)

Explanation:

The force between two charges is given by :

Where

d is the original distance

Let d' is the new distance such that, r' = r/3

New force,

[tex]F'=\dfrac{kq_1q_2}{r'^2}\\\\F'=\dfrac{kq_1q_2}{(\dfrac{r}{3})^2}\\\\F'=9\times \dfrac{kq_1q_2}{r^2}\\\\F'=9F[/tex]

So, the new force becomes 9 times the initial force.

Explanation:

it is correct on Acellus

The total force on charge q(3) is 1125 x [tex]10^{-3}[/tex] Newton

We have three charges in a straight line.

We have to find the force on charge q3 due to charge q1 and q2.

The force between two point charges is directly proportional to the product of the magnitude of two point charges and inversely proportional to the square of the distance between them. Mathematically-

[tex]F = \frac{1}{4\pi\epsilon_{o}}{\frac{qQ}{r^{2} } } }[/tex]

We have -

[tex]q_{1} =q_{2} =q_{3} = -5 \times 10^{-6} C[/tex]

The distance between -

[tex]q_{1}\;and\;q_{2} = q_{2} \;and\;q{3}[/tex] = 0.5 m

Now, Force on charge q(3) due to charge q(1) -

F(1 → 3) = [tex]\frac{1}{4\pi\epsilon_{o}}{\frac{5\times 10^{-6} \times 5\times 10^{-6} }{1^{2} } } } = 9\times 10^{9} \times 25 \times 10^{-12} = 225\times 10^{-3}[/tex] N (repelling force)

Force on charge q(3) due to charge q(2) can be calculate similarly as -

F(2 → 3) = 900 x [tex]10^{-3}[/tex] N(repelling force)

Now, both the forces are in same direction, so we can add them algebraically -

[tex]F_{net}[/tex] = F(1 → 3) + F(2 → 3) = 1125 x [tex]10^{-3}[/tex] N

Hence, the total force on charge q(3) is 1125 x [tex]10^{-3}[/tex] Newton

Hence, the wavelength of light in nano meters is 0.0177 x   nm.
