Answer:

The property of concave mirror says that the line which is coming beyond center of curvature will come back to focus and parallel to the focus

And the image will be between center of curvature and focus. And arrow shows the image the way it will appear.

Please look at the attachment to see the object

Therefore, option D is correct that is it will be smaller than the vase and inverted.

Alike because they both act on the quarks making up the nucleons and they have very short ranges. The Strong Nuclear Force is an attractive force between protons and neutrons that keep the nucleus together and the Weak Nuclear Force is responsible for the radioactive decay of certain nuclei. Which also makes them very different

A migrating robin flies due north with a speed of 12 m/s relative to the air. The air moves due east with a speed of 6.7 m/s rel

mafiozo [28]

Here it is given that speed of migrating Robin is 12 m/s relative to air

so we can say that

$\vec v_{ra} = 12 m/s$ North

so it will be

Let North direction is along Y axis and East direction is along X axis

$\vec v_{ra} = 12\hat j$

also it is given that speed of air is 6.7 m/s relative to ground

$\vec v_a = 6.7 \hat i$

now as we know by the concept of relative motion

$\vec v_{ab} = \vec v_a - \vec v_b$

$\vec v_{ra} = \vec v_r - \vec v_a$

now by rearranging the terms

$\vec v_r = \vec v_{ra} + \vec v_a$

$\vec v_r = 12 \hat j + 6.7 \hat i$

now we need to find the speed of Robin which means we need to find the magnitude of its velocity which we found above

So here we will say

$v_r = \sqrt{12^2 + 6.7^2}$

$v_r = 13.7 m/s$

so the net speed of Robin with respect to ground will be 13.7 m/s

Answer: Frequency distribution helps to understand data. some complex data needs to be converted into intervals to see its frequency of occurrence. it helps to find the mean median and mode of the data. It helps in the analysis of data and its practical implementation.

Which statement about ocean surface currents is false?

Alla [95]

A) they have no effect on air temperature over land on the coast is False

Explanation:

warm and cold ocean currents can influence the coastal areas only when the air is blown into the land from the sea.
the temperature over the land increases when warm ocean currents heat the air above the ocean.
the temperature over the land decreases when cold ocean currents cool the air above the ocean and can bring colder winds to the coastal regions.
so, ocean currents play a major role in regulating the air temperature over land on the coastal region.
