Can someone help me please.

Answer:

The hydraulic press allows the applied force (F1) to be converted into a higher force (F2) along some path as many times as the surface of the driven hydraulic cylinder (A2) is larger than the surface of the driving hydraulic cylinder (A1). The hydraulic press works on the basis of Pascal's law, which reads: External pressure is transmitted through the fluids equally in all directions.

There are many factors that determine the affordability of a planet, than its distance from the sun. It is clear that the solar radiation received by humans cannot be greater or less than certain values recommended by scientists.

However this planet may have a stronger magnetic field that diverts in large quantities the dangerous radiation that can reach Kepler-186f, in the same way the star of this planet may have less intense radiation than our sun.

These factors can be seen in an easier way by investigating the properties of the planet Kepler-186f  which must be different from the planet Earth.

answer: Its sun is cooler than our sun, so there is a possibility that water can exist in liquid state on this planet.

According to Snell's law :

Sin i / Sin r = refractive index

[tex]r = sin^{ - 1} ( \frac{sin \: i}{1.33} ) = sin^{ - 1} (0.3)[/tex]

[tex]angle \: of \: refraction = 17.45°[/tex]

Therefore, angle of refraction is less than angle of incidence because the light ray bends towards the normal when it travels from rarer to denser medium

Answer:

The minimun distance to the Cobra should be about 3.5 [m]

Explanation:

This problem can be solved using kinematics equations, and by means of the following equation:

v = x/t

where:

v = velocity = 3.5 [m/s]

t = time = 1 [second]

x = distance of the attack

x = 3.5*1  = 3.5 [m]

Physical science is the study of the inorganic world. That is, it does not study living things. (Those are studied in biological, or life, science.) The four main branches of physical science are astronomy, physics, chemistry, and the Earth sciences, which include meteorology and geology.

Answer:

Physical science is a branch of natural science that studies non-living systems, in contrast to life science. It in turn has many branches, each referred to as a "physical science", together called the "physical sciences".

Answer:

ase of convenience, since the beneficiary by having a burrow and the shrimp benefits from knowing that there are predators nearby.

Explanation:

This exercise asks to study the dependence between two animals, the shrimp and the puffer fish.

Two types of dependency are defined:

* Complete. What is when one animal lives off the other

* Convenience if one animal does not live on the other

In this case, both the shrimp and the predator do not live on each other, since they feed independently.

So it is a case of convenience, since the beneficiary by having a burrow and the shrimp benefits from knowing that there are predators nearby.

The correct answer is: the balloon benefits by getting a burrow to live in and the shrimp knows when predators are nearby.

Lithification is a process of  forming sedimentary rock. The correct option is D.

The challenging process of lithification converts loose silt grains that have recently been deposited into rock. Once a silt is deposited, lithification may occur immediately or later. Cementation is one of the crucial processes, particularly for sandstones and conglomerates.

Fresh sediment is often a loose substance that has several pores or open holes that are either filled with air or water. Lithification works to fill in the reduced pore space with a mineral deposits substance. Compaction and cementation are the major lithification processes.

Answer:

74 km

Explanation:

Ler the position of markers be A,B, and C for notation 246 km, 172 km, and 147 km respectively. John's whole journey has been shown in the figure.

As given,his initial position was the point A. At first, he travelled from the point A to C, then he traveled back from the point C to B on the straight path. His final position is at the point B.

The resultant displacement equals to the shortest distance between the final and the initial positions.

So, the magnitude of the resultant displacement is |172-246| km=74 km and the direction is towards point B from point A.

Answer:

The value is [tex]t = 689.029 \ hours [/tex]

Explanation:

From the question we are told that

The molar mass of hydrazine is [tex]Z = 32 g/mol = \frac{32}{1000} = 0.032 \ kg/mol[/tex]

The initial temperature is [tex]T_i = -186 ^o F = (-186-32) *\frac{5}{9} +273.15 = 152\ K[/tex]

The final temperature is [tex]T_f = 78 ^o F = (78-32) *\frac{5}{9} +273.15 = 298.7 \ K[/tex]

The specific heat capacity is [tex]c_h = 0.099 [kJ/(mol K)] = 0.099 *10^3 J/(mol/K)[/tex]

The power available is [tex]P = 300 \ W[/tex]

The mass of the fuel is [tex]m = 1640 \ kg[/tex]

Generally the number of moles of hydrazine present is

[tex]n = \frac{m}{Z}[/tex]

=> [tex]n = \frac{1640}{= 0.032}[/tex]

=> [tex]n = 51250 \ mol[/tex]

Generally the quantity of heat energy needed is mathematically represented as

[tex]Q = n * c_h * (T_f -T_i)[/tex]

=> [tex]Q = 51250 * 0.099 *10^3 * (298.7 - 152)[/tex]

=> [tex]Q = 7.441516913 * 10^{8} \ J[/tex]

Generally the time taken is mathematically represented as

[tex]t = \frac{Q}{P}[/tex]

=> [tex]t = \frac{7.441516913 * 10^{8} }{300}[/tex]

=> t = 2480505.6377 s

Converting to hours

[tex]t = \frac{2480505.6377}{3600}[/tex]

=> [tex]t = 689.029 \ hours [/tex]

The expression for thermal energy and power we were able to find the time necessary to heat the fuel is t = 689 h

To find

The international measurement system (SI) establishes the fundamental units in the measurement processes, this is defined by convention, giving uniformity in the calculation process and measurement exchange. Before starting the exercise we must reduce the magnitude to the SI system

          PM = 32 g / mol ([tex]\frac{1 kg}{1000 g}[/tex] g) = 32 10-3 kg / mol

          T₀ = 5/9 (ºF -32) + 273.15 = 5/9 (186 32) +273.15 = 152.0 K

          T_f = 5 * (78 - 32) +273.15 = 298.7 K

          c_e = 0.099 kj / mol k ([tex]\frac{1000J}{1 kJ}[/tex]) = 0.099 10³ J / mol K

The mole is the amount of matter of the international system (SI), the moles exist must be calculated since they are the mass of the compound for this we use a direct rule of proportions, if a mole has more than 32 10⁻³ kg, when moles are 1640 kg

           n = [tex]\frac{m}{PM}[/tex]

           n = 1640/32 10⁻³

           n = 51.25 10³ mol

If we assume that all energy transfer is thermal, we can use  

           Q = [tex]m\ c_e ( T_f - T_o)[/tex]

           Q = 51.25 10³ 0.099 10³ (298.7 -152.0)

           Q = 7.44 10⁸ J

Power defined by the relationship between work and time

           P = [tex]\frac{W}{t}[/tex]

In this case the thermal work is equal to the heat ( W=Q)

           t = [tex]\frac{Q}{P}[/tex]

           t = 7.44 10⁸ / 300

           t = 2.48 10⁶ s

They indicate that the answer is given in hours, let's reduce the time

           t = 2.48 106 s (1h / 3600s)

           t = 6.89 10² h

In conclusion, with the relationship of thermal energy and power, we were able to set the time necessary for the amount of fuel to be t = 689 h

100/5=20

Thus in 100 seconds the boy would have traveled a distance of 10 meters 20 times.

10*20=200

If the boy travels 10meters in 5 seconds, he travels 200m in 100seconds.

Here, we know that the the total distance is 10m and the total time is 5s . so the avg. speed is 10m5s=2m/s .
