Darya [45]2 years ago

Answer:

Their primary way of spreading is from human activities, they can quickly travel around the world for example these new "murder" hornets that can kill a large bee hive with one sting, they traveled all the way from Asia. Invasive species can also be through people's luggage, small boats, planes and large shipment like cargo carriers. I hope this helps. : )

Which example does not describe a behavioral adaptation? A. A squirrel buries acorns to dig up and eat later. B. A honeybee does

chubhunter [2.5K]

The answer is B) A honeybee does a dance to tell the other bees where to find flowers.
Honeybees do not dance, first of all.
Second, that is not an adaptation. That is more like a message. An adaptation is changing to the environment to survive. This is not changing to the environment. They are just signaling the other bees.
A, C, and D are all adaptations. They change so that they can survive. They do a different method than usual.

Which of the following statements are true about the lenses used in eyeglasses to correct nearsightedness and farsightedness? (T

Slav-nsk [51]

Answer:

A: They produce a real image.

Explanation:

The images formed on the retina of the eye for a normal visibility must always be real.

Only a real image can be physically projected on any physical object whereas the virtual images are visible due to reflections.

The nearsightedness is corrected with the help of a concave lens since it is the condition of the eye lens remaining thick and curved to converge the rays entering the eyes after a shorter distance which results in their image formation even before the retinal surface so to initially diverge them a bit so that they converge on the retinal surface and form the image there we use concave lens. Vice-versa of the above justification in the case of farsightedness.

Hola tengo un taller de física y nose como resolver este pregunta

Blizzard [7]

a) 0.26 h

b) 71.4 km

Explanation:

In order to solve the problem, we have to know what is the final velocity of the car.

Here, we assume that the final velocity reached by the car is

$v=300 km/h$

Therefore, we can find the time taken by the car to reach this velocity by using the suvat equation:

$v=u+at$

where:

u = 250 km/h is the initial velocity

$a=190 km/h^2$ is the acceleration of the car

v = 300 km/h is the final velocity

t is the time

Solving for t, we find:

$t=\frac{v-u}{a}=\frac{300-250}{190}=0.26 h$

In order to find the distance covered by the car, we can use the following suvat equation:

$s=ut+\frac{1}{2}at^2$

where:

s is the distance covered

u is the initial velocity

a is the acceleration

t is the time

For the car in this problem, we have:

u = 250 km/h

t = 0.26 h (calculated in part a)

$a=190 km/h^2$

Therefore, the distance covered is

$s=(250)(0.26)+\frac{1}{2}(190)(0.26)^2=71.4 km$

Calculate the magnitude of the electric field at one corner of a square 1.10 m on a side if the other three corners are occupied

natka813 [3]

The direction of magnetic field is south-east and the magnitude is

$23.66$ × $10^{3} N/C$ .

Here, the magnitude of CD and BC will be cancelled, as they both are in the opposite direction and equal to each other.
the magnitude, towards the diagonal AC will result in CP, which is the direction of the electric field.

magnitude of electric field can be defined as :- The force per charge on the test charge is a straight forward way to define the size of the electric field.

To find the magnitude of the electric field use the formula

$E = kq/ r^{2}$
