Answer:

A woman births a child out of her va**na

Explanation:

When a man and woman have a thing called intercourse, the sperm and egg mix (or something like that) which creates the fetus (I think?) and 9 months later a baby is born out of the woman's va**na

How high does a rocket have to go above Earth's surface before its weight is half of what it is on Earth?

Contact [7]

Answer:

$h=1.6\times 10^6\ m$

Explanation:

As we know that the acceleration due to gravity decreases with height.

At certain height it will get to the half of its value on the surface of the earth.

As we know that the weight on the surface of the earth is given as:

$w=m.g$

where:

m = mass of the object

g = acceleration due to gravity of the substance

Since mass of the substance is constant so the variation is weight is possible only due to change in the acceleration due to gravity.

We know that the variation of the acceleration due gravity with height is given as:

$g_{_h}=g\times (1-\frac{2h}{R} )$

where:

$g_{_h}=$ value to acceleration due to gravity at height h

g = acceleration due to gravity at the earth's surface

h = height of the object

R = radius of the earth = $6400\ km$

according to question the weight becomes half, so,:

$4.9=9.8\times (1-\frac{2h}{6400\times10^3} )$

$h=1.6\times 10^6\ m$ is the height a rocket has to go above Earth's surface before its weight is half of what it is on Earth.

which of the following is true in regard to a charged atom? a. when an atom loses an electron, it becomes an anion, which is neg

3241004551 [841]

Among the choices provide, the one statement that is true with regards to a charged atom is C, the number of protons and the number of electrons within the same atom are unequal. A charged atom is called an ion. Atoms are nonpartisan since they have similar quantities of positive and negative charges.

A diffraction pattern is formed on a screen 130 cm away from a 0.420-mm-wide slit. Monochromatic 546.1-nm light is used. Calcula

notka56 [123]

Answer:

The fractional Intensity $\frac{I}{I_{max}}$ = 0.0146

Given:

wavelength of the light, $\lambda = 546.1 nm = 546.1\times 10^{-9} m$

slit and screen separation difference, D = 130 cm = 1.3 m

distance of the point from the center of the principal maximum, y = 4.10 mm = 0.041 m

slit width, d = 0.420 mm = $0.420\times 10^{-3}$

Solution:

To calculate the fractional intensity, we use the given formula:

$\frac{I}{I_{max}} = \frac{sin^{2}\delta }{\frac({\delta}{2})^{2}}$ (1)

$\delta = \frac{\pi }{\lambda}dsin\theta$

For very small angle:

$\delta = \frac{\pi dy}{\lambda D}$ (2)

where

$\delta = total phase angle$

$\theta = angle of deviation$

Using eqn (2):

$\delta = \frac{\pi \times 0.42\times 10^{-3}\times 4.1\times 10^{-3} }{546.1\times 10^{-9}\times 1.3} = 7.6202 radians$

Now, using eqn (1):

$\frac{I}{I_{max}} = \frac{sin^{2}(7.6202) }{(\frac{7.6202}{2})^{2}} = 0.0146$

Ordinarily, material presented ________ is usually the most difficult to remember due to interference

Brums [2.3K]

Memorizing items on a list are enabled by the effects of primacy and

recency.

Ordinarily, material presented in the middle of a list is usually the most

difficult to remember due to interference.

Reasons:

When memorizing a list of items, due to the primacy effect, the information

at the beginning of the list are given importance, in the brain, due to their

many attributes, which may be due to them being;

The first item

Definition of the task (assignment of importance level)

Idea of what to expect (preparation of the mind)

Also the last items on the list are recalled by the effect known as recency,

which is probably due to the tendency to store items in the short term

memory.

Therefore, in the course of memorizing a list, the first items on the list can

be stored in the long-term memory. The items that comes last in the

list are stored in the short-term memory, while the material presented in

the middle of the list are not allocated to a storage, and are usually

the most difficult to remember due to interference, by other items that

tend to come up during the retrieval process, from the long-term memory.

(Rearranging the list can aid total recall)
