Explanation:
Toughest animal existing now would be like a bear more specifically a grizzly bear. I say this because when your near this animals and your messing with it or it's cubs your more than likely dead you climb up a tree,did you forget they can climb to,when running a grizzly bear can get up to a max speed of 35 MPH, Now the grizzly bear isn't the most aggressive but is still one of the rulers of bears along with it's relative the polar bear,but when you are talking about pain they can't take pain shoot them it takes more than 1 show better have a machine gun or be able to run fast a knife isn't going to do a lot in less you get it in it's eye. Now for a grizzly bear you can play dead and he will fall for it or she but all you need to know is don't mess with it.
Another one of the toughest animal is a komodo dragon.
When were talking about a komodo dragon there like a human they way up to 170 LBS to 200 LBS they have a length of 8 foot and a half. Now komodo dragons are very friendly and can be a family pet but if that thing bites you,you will be dead within hours in less treated amindentally. The komodo dragon can kill water buffalos, and the komodo dragon has no predators. The komodo dragon is the biggest lizard in the world and is poisonous so that is a reason to not get around with, one time a komodo dragon killed an eight year old boy so not really friendly.
is there anymore things you want my opinion on on actually the real deal.
would you like to know most aggressive,
most dangerous,
most poisonous,
The most feared
the most loving
The biggest animal in the world
The most friendly or other just let me know:)
Hope it helps have a great afternoon:)

The cylinder in the picture is rotating at 500 RPMs. The friction coefficients between the cylinder and block B are static=0.5 and kinetic=0.3. Assume both blocks are attached together. Determine if the block system will slide down or not.
Coefficient of static friction = 0.5Coefficient of Kinetic friction = 0.3Angular velocity = 500 RPMsThe Radius of the System
Let R be the radius of cylinder
[tex]m_a + m_b = 4 + 3 = 7kg[/tex]
The angular velocity is 500 RPMs
[tex]\omega ^2 = \frac{500 * 2\pi}{60} rad/s\\N = (M_a + M_b)\omega ^2 R[/tex]
The normal force
[tex]f = \mu N = (M_a + M_b) g\\\mu (M_a + M_b) \omega ^2 R = M_a + M_b\\R = \frac{1}{\mu \omega ^2 R}\\\mu_s = 0.5\\R = \frac{1}{0.5 * (\frac{500 * 2\pi}{60})^2 }\\R = 0.0073m\\R = 7.3mm[/tex]
Since the radius is very little for two block to execute circular motion so system will slide down.

what is an electric current ?
Answer:
An electric current is a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space. It is measured as the net rate of flow of electric charge through a surface or into a control volume.
Explanation:
students in a lab are doing experiments involving the motion of objects. they pull an object across a table and use a detector to measure the acceleration of the object for the entire time they pull it. The graph shows the data from the detector, with four segments labeled
Based on the acceleration-time graph, the segments of the motion in which the object experience a net force are both 1 and 3.
What is Newton's Second Law of Motion?Newton's Second Law of Motion states that the acceleration of an object is inversely proportional to its mass and directly proportional to the net force acting on the physical object.
How to calculate the net force.Mathematically, the net force acting on the car is given by Newton's Second Law of Motion:
[tex]F=ma =\frac{m(v\;-\;u)}{t}[/tex]
Where:
m is the mass.t is the time.u is the initial velocity.u is the final velocity.a is the acceleration.Note: Mass represents the conversion factor between net force and acceleration on an acceleration-time graph.
Based on the acceleration-time graph, the segments of the motion in which there is a net force acting on the object are both 1 and 3 while it experienced constant acceleration at segment 2 and 4.

A delivery drone uniformly slowed down from 45 m/s to 23 m/s in a straight line over a 30-minute duration within a 16-
kilometer radius of its warehouse. What was the magnitude of its average acceleration?
Answer: The Answer is A 1.2 x 10−2 m/s2
The average acceleration of the delivery drone as it slowed down was -0.012 m/s².
What is average acceleration?The average acceleration is defined as the average rate of change of velocity with respect to time. Mathematically -
a = Δv/Δt
Given is a delivery drone that uniformly slows down from 45 m/s to 23 m/s in a straight line over a 30-minute duration.
We can write -
[u] = 45 m/s
[v] = 23 m/s
Δt = 30 min = 30 x 60 = 1800 sec
We can write the average acceleration as -
a = Δv/Δt
a = (23 - 45)/1800
a = - 0.012 m/s²
Therefore, the average acceleration of the delivery drone as it slowed down was -0.012 m/s².

11. Differentiate between refraction of light and dispersion of light.
Answer:
Refraction refers to any bending of waves due to a change in speed. In the case of light being refracted by a prism, dispersion means that the higher the frequency light bends more. In short, Refraction is the bending of light and Dispersion is the frequency dependece of this behaviour.

If a person weighs 692 N on earth and 5320 N on the surface of a nearby planet, what is the acceleration due to gravity on that planet?
Answer:
Approximately [tex]75.3\; \rm m \cdot s^{-2}[/tex]. (Approximately [tex]7.69\, g[/tex], where [tex]g[/tex] denotes the acceleration due to gravity on the surface of the earth.)
Explanation:
The weight of an object is the size of the overall gravitational pull on that object. If the mass of this person is [tex]m[/tex], the weight of this person at a point with gravitational acceleration [tex]g[/tex] would be [tex]m \cdot g[/tex].
Let [tex]g_{0}[/tex] denote the gravitational acceleration on the surface of the earth. The weight of this person on the surface of the earth would be [tex]m \cdot g_0[/tex].
Let [tex]g_1[/tex] denote the gravitational acceleration on the surface of that "nearby planet". The weight of this person on the surface of that planet would be [tex]m \cdot g_1[/tex].
According to the question:
Weight of this person on the surface of the earth: [tex]692\; \rm N[/tex]. Therefore, [tex]m \cdot g_0 = 692\; \rm N[/tex].Weight of this person on the surface of that nearby planet: [tex]5320\; \rm N[/tex]. Therefore: [tex]m \cdot g_1 = 5320\; \rm N[/tex].Take the quotient of these two equations:
[tex]\displaystyle \frac{m\cdot g_1}{m \cdot g_0} = \frac{5320 \; \rm N}{692\; \rm N}[/tex].
[tex]\displaystyle \frac{g_1}{g_0} \approx 7.6879[/tex].
[tex]g_1 \approx 7.6879 \, g_0[/tex].
In other words, the gravitational acceleration on the surface of that nearby planet is approximately [tex]7.6879[/tex] times the gravitational acceleration on the surface of the earth.
The gravitational acceleration on the surface of the earth is approximately [tex]g \approx 9.8\; \rm m \cdot s^{-2}[/tex]. Therefore, the gravitational acceleration on the surface of that planet would be approximately [tex]7.6879\, g \approx 7.8679 \times 9.8\; \rm m \cdot s^{-2} \approx 75.3\; \rm m \cdot s^{-2}[/tex].
Now imagine everyone in the group hug starts moving away from each other what effect do you think that would have on your temperature
temperature would decrease because you aren’t close to other bodies with similar temperatures, you are now surrounded by air that is cooler than you. the molecules move from hot to cold always.
What is Temperature?Temperature is a unit used to describe hotness or coldness. It can be stated in terms of any number of arbitrary scales and shows the direction in which heat energy will naturally flow, i.e., from a hotter body to a colder body (one at a lower temperature).
Temperature is not the same as the energy of a thermodynamic system; for instance, an iceberg has a significantly larger total heat energy than a match, despite the fact that a match is burning at a much higher temperature.
As opposed to extensive characteristics, like mass or volume, temperature is referred to as an intense property—one that is independent of the quantity of matter being considered—along with pressure, density, and other comparable properties.
Therefore, temperature would decrease because you aren’t close to other bodies with similar temperatures, you are now surrounded by air that is cooler than you. the molecules move from hot to cold always.
