because the top part become weaker

Explanation:

Unfortunately, all trees have some potential to fail during heavy winds or other harsh elements, such as snow and ice. ... In these incidences, the tree trunk acts as a lever and the force applied to the roots and trunk increases with height and mass. Taller trees are more susceptible to windthrow.

"Windthrow" is a phenomenon that uproots a tree because the trunk acts as a lever applying force to the roots. ... Trees are more likely to uproot during strong winds especially if the tree is top-heavy which can also result in tearing, splitting and limb breakage

Answer:

Mass of object = 8kg

Explanation:

= 1.5

You can now solve for your unknown value of mass.

A net force of 12.0 N causes an object to increase its speed from 15.0 m/s to 18.0 m/s during a 2.0 second interval. The mass of the given object 8 Kg.

A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

Since a = change in v/ change in t,

a = (18-16)/2

a = 1.5

Force, f = ma

mass, m = F/a

          m = 12/1.5

          m = 8 Kg.    

A net force of 12.0 N causes an object to increase its speed from 15.0 m/s to 18.0 m/s during a 2.0 second interval. The mass of the given object 8 Kg.

Answer:

its electric current

Explanation:

Answer:

P.E = 25.48 Joule

Explanation:

Here,

mass (m) = 2kg

height (h) = 1.3m

g = 9.8m/s^2

P.E = mgh

= (2) (9.8) (1.3)

P.E = 25.48 Joule

Thus, the potential energy of a 2kg plant that is on a windowsill 1.3m high is 25.48 Joule

Answer:B. A segment of a DNA molecule

Explanation:

Answer: Because machines cannot create new energy themselves, they merely change its direction, its form, the amount applied, or the distance it is applied over. Therefore, although it may seem like machines make things easier, in reality they just convert one form of energy into another, and cannot multiply energy or work.

Answer:

-12.38 N

Explanation:

This question requires you to first find the acceleration then apply Newton's 2nd law of motion to find the force.

To find deceleration use the formula;

v²= u²+2ad ---where

v= final speed = 0 m/s

u= initial speed = 3.0 m/s

a= acceleration { in this case , deceleration} = ?

d= distance from the point where its passenger rolled off= 4.0 m

therefore ;

[tex]a=\frac{v^2-u^2}{2d}[/tex]

[tex]a=\frac{0^2-3^2}{2*4} =\frac{-9}{8} m/s^2[/tex]

Mass of the sled is calculated from its weight force.

Weight force = mg

mass of sled = weight force / g  where g= 10 m/s²

mass of sled = 110/10 = 11kg

The magnitude of horizontal net force will be : F= ma  where ;

m= mass of sled = 11 kg

a= deceleration = -9/8 m/s²

F = 11 * -9/8 = -12.38 N

Force is acting on the opposite direction of the initial motion of the sled.

The magnitude of the horizontal net force acting on the sled is 12.375 N.

Given data:

The initial speed of sled is, u = 3.0 m/s.

The final speed of sled is, v = 0 m/s.

The distance covered before stopping is, s = 4.0 m.

The weight of sled is, W = 110 N.

Using the Newton's second law, the net horizontal force acting on the sled is given as,

F = ma

here,

m is the mass of sled.

a is the acceleration of sled.

Mass is calculated from the weight as,

W = mg

110 = m (10)

m = 11 kg.

Now, using the second kinematic equation of motion to obtain the acceleration of sled as,

[tex]v^{2}=u^{2}+2(-a)s\\\\0^{2}=3^{2}+2(-a)4\\\\8a=9\\\\a=1.125 \;\rm m/s^{2}[/tex]

Then the magnitude of net horizontal force is,

[tex]F = ma\\\\F = 11 \times 1.125\\\\F = 12.375\;\rm N[/tex]

Thus, we can conclude that the magnitude of the horizontal net force is 12.375 N.

Answer:

Explanation:

Element: consists of only one kind of atom, can't be broken down into a simple type of matter by either physical or chemical means and can consist as either atoms or molecules

Compound: consists of atoms of two or more different elements bound together, can be broken down into simpler types of matter by chemical means BUT not by physical means, has properties that are different from its component elements and always contain the same ratio of its component atoms.

Electromagnetic wave has a high frequency and can travel in a vacuum or space.

It has a high frequency and can travel in a vacuum or space is the statement which best describes an electromagnetic wave having shorter wavelength because electromagnetic waves having shorter wavelength has high frequency and it can propagate through space means need no medium for propagation.

The transmission of electromagnetic waves does not require a medium and they are able to travel through vacuums or space. Ultraviolet light, X-rays, and gamma rays are the examples of electromagnetic waves so we can conclude that electromagnetic waves having shorter wavelength has high frequency and it can propagate through space.

Explanation:

Speed, being a scalar quantity, is the rate at which an object covers distance. The average speed is the distance (a scalar quantity) per time ratio. ... Velocity is the rate at which the position changes. The average velocity is the displacement or position change (a vector quantity) per time ratio.

Answer:

It’s both I and II

Explanation:

Speed refers to how fast something goes by using the equation distance/time. So it only uses distance and time.

On the other hand velocity is basically speed, so it uses distance/time, but the only difference is velocity uses direction.

Explanation:

Answer:The croquet ball velocity v will be 56/500 the tennis ball velocity V after the impulse.

The second law (force = mass*acceleration) says that the same force will accelerate the balls by the inverse of their mass. That is, the force will continuously change the momentum:

f = 500a = 56A

Therefore a = f/500 and A = f/56

and a/A = 56/500.

The croquet ball will accelerate less, for whatever time or distance you apply the force.

The third law: for every action, there is an equal and opposite reaction. So, if in fact you apply the same force to strike each ball, you will feel the same reaction. That’s probably easier to do for a quick strike (the impulse case above) than for a long, smooth acceleration over distance, because the balls have very different elastic response. The body can tell how equally you applied force!

Answer:

120 miles/hour

Explanation:

The average speed is the ratio of total distance covered by an object or a body to the total time taken to cover the distance.

Mathematically,

    Average speed = total distance covered/total time taken

In the case of Connie:

total distance = 180 + 180 = 360 miles

In order to calculate the time for each trip

speed = distance/time

  time = distance/speed

From Phoenix to flagstaff:

  time = 180/180 = 1 hour

From flagstaff back to Phoenix:

  time = 180/90 = 2 hours

total time taken = 1 + 2 = 3 hours

Average speed = 360/3 = 120 miles/hour

Hence, the average speed is 120 miles per hour.
