Explain why it is esaier to climb a mountain on a zigzag path rather than one straight up the side. is your increase in gravitat

ional energy the same in both cases?

Answer:

More work done with less power

The increase in gravitational energy is the same as the height which is a function of gravitational energy is the same in both cases

Explanation:

Climbing the mountain in zigzag pattern is easier because

1. The time it takes to climb increases so that the required power or rate of doing work decreases

2. Climbing in zigzag pattern affords the use of leverages by the sides

3. Similar mechanical power gain and efficiency from using a drive screw instead of a nail to fasten items together can be achieved

The increase in gravitational energy is the same gravitational energy ~ mass × gravity ×height

The movement of the planets and other celestial bodies in the Solar System is caused by
Anvisha [2.4K]

The movement of the planets and other celestial bodies in the solar system is actually caused by the sun's gravitational pull or force.

Just like the moon orbits the earth because of the gravitational pull by the earth so does gravitational pull by the sun causes planets' and other celestial bodies' orbit.

In a supermarket, you place a 22.3-N (around 5 lb) bag of oranges on a scale, and the scale starts to oscillate at 2.7 Hz. What
allsm [11]

Answer:

Force constant, k = 653.3 N/m

Explanation:

It is given that,

Weight of the bag of oranges on a scale, W = 22.3 N

Let m is the mass of the bag of oranges,

m=\dfrac{W}{g}

m=\dfrac{22.3}{9.8}

m = 2.27 kg

Frequency of the oscillation of the scale, f = 2.7 Hz

We need to find the force constant (spring constant) of the spring of the scale. We know that the formula of the frequency of oscillation of the spring is given by :

f=\dfrac{1}{2\pi}\sqrt{\dfrac{k}{m}}

k=4\pi^2 f^2m

k=4\pi^2 \times (2.7)^2\times 2.27

k = 653.3 N/m

So, the force constant of the spring of the scale is 653.3 N/m. Hence, this is the required solution.

Give a brief description of the factors involved in understanding the etiology of a disease.
zysi [14]

\mathfrak{\huge{\pink{\underline{\underline{AnSwEr:-}}}}}

Actually Welcome to the Concept of the Diseases.

When a doctor tries to figure out the cause of a disease, they are actually trying to figure out the etiology of the disease.

Etiology is the cause of a disease or the science that deals with such causes.

The word etiology comes from the Greek etio-, which means 'causation' and -ology, which refers to the scientific study of something (here relates to study or research on disease).

A disease's etiology, or cause, generally falls into three main categories; intrinsic, extrinsic and idiopathic.

1.) Intrinsic means coming from within. Therefore, any pathological, or disease-causing, change that has occurred from inside the body has occurred as a result of intrinsic factors.

e. g. Inherited conditions, or conditions that are passed down to you from your parents. An example of this is hemophilia, a disorder that leads to excessive bleeding.

2.)The second category of disease etiology is extrinsic etiologies. This means the cause of the disease, or pathological change, came from outside of the body.

e. g. Infectious agents like bacteria, viruses, fungi, and parasites.

3.)The third and final category of disease etiology is idiopathic, or of unknown cause.

e. g. It may be sudden pain in stomach,etc.
