How far does an object go after the pushing force is removed till it stops. the object's speed is 1.70 m/s when the pushing force is removed. friction is 52.0 n and mass of object is 80.0kg

The speed of water at the end of spillway is 57.7 (m/s)

Calculation:

According to the Bernoulli equation:

P/? + v^2/2 + gz = constant

However, the atmospheric pressure and density are essentially the same at the peak and bottom of the falls. Therefore,

v^2/2 + gz = constant , so:

v_bottom^2/ 2 = v_top^2/2 + gz, or:

v_bottom = sqrt(v_top^2 + 2gz) = sqrt(v_top^2 + 2g*170)

If v_top ~ 0, then:

v_bottom ~ sqrt(2gz) = sqrt(2*9.8*170) = 57.7 (m/s)

The 3 resistors on the upper side of the circuit are linked in series in this instance, and the total resistance R1 is expressed as 1+1+1=3.

The combined resistance R2 is expressed as 2+2+2=6 due to the series connection of the three 2-ohm resistors on the lower part of the circuit. The intermediate resistances R1, R2, and 2 are linked in parallel. This parallel connection's total resistance, R3, is therefore represented as 2/1+ 2/1+ 6/1 = 1/1=1 ohm.

The maximum height of the particle is 100feet

Applying linear motion equations,

v^2 = u^2 - 2as

v = final velocity

u = initial velocity

g = acceleration due to gravity

s = height travelled

At max height,

velocity = 0 i.e. V=0,  initial velocity u = 16ft/sec

g = 32ft/[tex]sec^{2}[/tex]

so we have

0 = [tex]u^{2}[/tex] -2gs

S = [tex]u^{2}[/tex]/2g

= 16*16/2*32

= 4 feet

So maximum height = initial height + height travelled

= 96 + 4 = 100 feet

The range is u2sin2g and the needed value of the maximum height is u2sin2g. Not to be confused with flying time is the maximum height attained.

As the liver cells of animals, carbohydrates are kept in glycogen granules close to the inner membrane. On demand, these release energy.

In addition to human muscle and liver cells, other cells such as those in the brain, heart, smooth muscle, kidney, red and white blood cells, and even adipose tissue also store modest amounts of glycogen.

Glucose is stored in the form of glycogen. It is a sizable, multi-branched polymer of glucose that is converted back into glucose in response to glucagon and accumulates in response to insulin. The fact is that because fat is such an energy-dense molecule and contains so many calories per gram, ounce, or pound, it is far simpler to lose weight when your body burns carbohydrates instead of fat.

An electric field is the physical field that surrounds the electrically charged particles and exerts force on all other charged particles in the field, either attracting or repelling them. It also refers to physical field for a system of charged particles. Electric fields originate from the electric charges and time-varying electric currents.

When a hydrogen atom forms a covalent link with an N, O, or F atom, hydrogen bonding takes place.

Only a few substances that contain hydrogen can form a hydrogen bond.

The hydrogen bonds in the CH4 molecule are visible.

When a F atom and a hydrogen atom are covalently bound, the hydrogen atom gains a slight positive charge.

Covalent bonds and hydrogen bonds are interchangeable terms.

The interaction known as hydrogen bonding, which involves a hydrogen atom sandwiched between two other atoms with a high affinity for electrons, is stronger than van der Waals forces but weaker than ionic or covalent bonds. Atoms in separate molecules or distinct regions of the same molecule can form hydrogen bonds with one another. A hydrogen atom (FH, NH, or OH) is covalently bound to one of the pair's (the donor) typically fluorine, nitrogen, or oxygen atoms, with which it shares electrons unevenly. As a result of this high electron affinity, the hydrogen gains a little positive charge. The other atom in the pair, which is usually F, N, or O, has an unshared electron pair, giving it a little negative charge.

The donor atom efficiently transfers its hydrogen to the receiver atom by electrostatic attraction, creating a connection. Water (H2O) is liquid over a much wider temperature range than would be anticipated for a molecule of its size due to its extensive hydrogen bonding. Because it quickly forms hydrogen bonds with the solute, water is an excellent solvent for ionic compounds as well as many other types of solutes. A linear protein molecule's ability to fold into its functional configuration depends on the hydrogen bonds formed between the amino acids. The double-helix structure of DNA is essential for the transmission of genetic information. It is created by hydrogen bonds between nitrogenous bases in nucleotides on the two strands of DNA (guanine partners with cytosine, adenine couples with thymine).

When the total debt ratio is 0.36, the debt-equity ratio is 0.5625.

The debt-to-equity ratio is a financial metric that shows how much debt and shareholder equity were utilized to finance the assets of a company. The ratio, often known as risk, gearing, or leverage, is closely related to leveraging. The debt-equity ratio serves as a gauge for how equally creditors and owners or shareholders contributed to the capital used by the company. The debt-equity ratio is the simple ratio of all long-term debt and equity capital in the company. The debt-to-equity ratio is calculated by dividing a company's total liabilities by the sum of its shareholders' equity. For the majority of businesses and industries, a desirable debt-to-equity ratio is around 2.0. A high debt-to-equity ratio shows that a business is using more market capital to finance its operations, whereas a low debt-to-equity ratio shows that the business is making better use of its assets and using less market capital. The debt-to-equity ratio is often higher in the capital industries.

Total Debt ratio = Debt/Asset

It is a component quantity of the various measurements used to sequence events, to compare the duration of events or the intervals between them, and to quantify rates of change of quantities in material reality or in the conscious experience. Time is often referred to as a fourth dimension, along with the three spatial dimensions.

Time has long been an important subject of the study in religion, philosophy, and science, but defining it in a manner applicable to all fields without circularity has consistently eluded scholars. Nevertheless, diverse fields such as the business, industry, sports, the sciences, and the performing arts all incorporate some notion of time into their respective measuring systems.

Time in physics is operationally defined as the "what a clock reads".

Examples of events are collision of two particles, the explosion of a supernova, or the arrival of a rocket ship. Every event can be assigned the four numbers representing its time and position (the event's coordinates).

However, the numerical values are different for the different observers. In general relativity, question of what time it is now only has meaning relative to a particular observer. Distance and the time are intimately related, and the time required for light to travel a specific distance is the same for all observers, as first publicly demonstrated by Michelson and Morley.

A ship travels 20 km to the south and then 40 km to the west. The ship's displacement from its starting point is approximately 44.7 km. Hence, the displacement is approximately 45 km.

Here, the calculation is done,

a = 20 km (southward movement)

b = 40 km (westward movement)

Now, one can find the displacement (d) using the Pythagorean theorem:

d² = a² + b²

d² = (20 km)² + (40 km)²

d² = 400 km² + 1600 km²

d² = 2000 km²

Now, by taking the square root of both sides to find the displacement (d):

d = √(2000 km²) d ≈ 44.7 km (rounded to one decimal place)
