251 atm pressure is transmitted in the hydraulic system.

According to Pascal's principle,

P₂ = P₁

⇒ F₁/A₁                                                      ( ∵ pressure = force / area)

⇒ F₁ /πr₁²

r₁ = 0.500 m /2 = 0.250 m

An applied force of 100 N to the brake pedal acts in the cylinder through a lever. This will exert a force of 500 due to the lever of the hydraulic system.

Hence, P₂ =F₁/πr₁²

                = 500 N/ π (0.250 × 10⁻²)²

                = 2.55 × 10⁷ Pa

Convert the unit of the pressure from Pa to atm

P₂ = 2.55 × 10⁷ Pa ( 1 atm /1.01325  10⁵ Pa)

     = 251 atm

Hydraulic systems function and carry out duties thru the use of a fluid that is pressurized. every other manner to put this is the pressurized fluid that makes things paintings. The energy of liquid gasoline in hydraulics is massive and as a result, hydraulics are generally used in heavy devices.

Answer:

the ans is 120 degree hope it will help

Answer:

The magnitude of acceleration is 2m/s² .

Explanation:

First, you have to find the velocity as it starts to travel 200m in 10s. The formula of velocity is V = Distance/Time, then you have to substitute the values into the formula :

\(v = d \div t\)

\(let \: d = 200 \\ let \: t = 10\)

\(v = 200 \div 10\)

\(v = 20m/s\)

Next, you have to substitute the values into the acceleration formula, a = (v-u)/t where v represents final velocity, u is initial velocity and t is time taken :

\(a = \frac{v - u}{t} \)

\(let \: v = 20 \\ let \: u = 0 \\ let \: t = 10\)

\(a = \frac{20 - 0}{10} \)

\(a = \frac{20}{10} \)

\(a = 2m/ {s}^{2} \)

Answer:

As altitude increases and atmospheric pressure decreases, the boiling point of water decreases.

We know

\(\boxed{\sf Power=\dfrac{Work\:done}{Time}}\)

\(\\ \sf\longmapsto Power=\dfrac{Force\times displacement}{Time}\)

\(\\ \sf\longmapsto Power=\dfrac{50\times 10}{10}\)

\(\\ \sf\longmapsto Power=\dfrac{500}{10}\)

\(\\ \sf\longmapsto Power=50W\)

This question involves the concepts of the equations of motion both in the horizontal motion and the vertical motion.

The rock hits "30.91 m" away from the base of the building.

First, we will calculate the time taken by the rock to reach the ground by applying the second equation of motion in vertical motion:

\(h=v_it+\frac{1}{2}gt^2\)

where,

h = height of the building = 30 m

vi = initial vertical speed = 0 m/s

t = time = ?

g = acceleration due to gravity = 9.81 m/s²

Therefore,

\(30\ m = (0\ m/s)(t)+\frac{1}{2}(9.81\ m/s^2)(t)^2\\\\t=\sqrt{\frac{(2)(30\ m)}{9.81\ m/s^2}}\\\\\)

t = 2.47 s

Now, we will calculate the horizontal distance by analyzing horizontal motion. Ignoring the air friction, the horizontal motion will be uniform:

\(s=vt\)

where,

s = horizontal distance = ?

v = horizontal speed = 12.5 m/s

Therefore,

\(s=(12.5\ m/s)(2.47\ s)\)

s = 30.91 m

The main advantage of a no-contact voltage indicator is that it is fast and safe to use. It can be used to detect live electrical circuits without touching the wires. They have an advanced internal circuitry that does not require physical contact with the live wire being tested.

They also work up to several hundred volts and are cost-effective. The no-contact voltage indicator, unlike the solenoid-type voltage tester, is ideal for quickly locating live wires or insulation flaws in electrical wiring. The use of a no-contact voltage indicator over a solenoid-type voltage tester offers great safety advantages.

A no-contact voltage indicator is a device that uses a sensing tip to detect the presence of AC voltage by either an LED indicator, audible alarm, or both. This type of voltage tester does not require physical contact with the surface being tested, making it a much safer testing method.

With no contact required, it eliminates the possibility of a shock should the solenoid-type tester contacts a live wire. In addition, this type of voltage indicator is able to determine if an outlet is wired correctly without having to insert a plug or other conductive device.

Answer:

The potential energy is zero since the rock isn't moving.

Answer:

Explanation:

It's not equal and opposite. You're thinking of Newton's 3rd Law. This is not that. This is gravitational attraction between 2 objects. We can figure out mathematically the pull that the earth has on a single person, by using the equation for gravitational force and the universal gravitational constant, G:

\(F_g=\frac{Gm_1m_2}{r^2}\) where G is the universal gravitational constant, m1 is the mass of one person, m2 is the mass of the earth, and r-squared is the addition of the radius of the earth plus the radius of you in relation to the surface of the earth.

Let's say a person weighs 150 pounds; in Newtons this is 667 N (rounded from 667.233); his mass then, in terms of the metric system (using 9.8 for gravity), is 68.2 kg. Let's also say that this person is 6 feet tall. 6 feet is the same as 1.83 m (rounded to 3 sig fig's) and the radius from that person's center to the surface of the earth would be about half that height at r = .915 meters. Filling in the formula:

\(F_g=\frac{(6.67*10^{-11})(68.2)(5.98*10^{24})}{(6.38*10^6)^2}\) it turns out that the person's radius adds nothing significantly to the radius of the earth, so it doesn't even count mathematically. It's way too small compared to the earth's radius (which is the denominator of that equation). We find that

\(F_g=668N\) That's the pull that the earth has on that person which, not coincidentally, is the weight in pounds we said that the person was. Isn't physics amazing!?

We need to calculate the energy possessed by the bullet due to its kinetic energy and then calculate the amount of ice melted by it.The amount of ice melted is 52.875 kg, or 52875 g. Therefore, the correct option is option c) (52.875 kg).

Using the equation for kinetic energy:

KE = 1/2 mv²

Where, KE is the kinetic energy,m is the mass of the bullet,v is the velocity of the bullet

Substituting the given values,KE = 1/2 × 0.05 kg × (840 m/s)²

= 176400 J

This energy gets converted into heat when it strikes the ice cube. The amount of heat required to melt a given mass of a substance is given by the specific heat of the substance using the formula: Heat required to melt = mass × specific heat × change in temperature

Here, the temperature change is from 0°C to 0°C, so it is 0. We need to find the mass of ice that would require this amount of heat to melt, so rearranging the above formula, we get: mass of ice = Heat required to melt / (specific heat × change in temperature)

Substituting the given values,

Mass of ice = 176400 J / (0.02 cal/g°C × 1°C × 4.184 J/cal × 1000 g/kg)

= 52.875 kg

= 52875 g

Therefore, the amount of ice melted is 52.875 kg, or 52875 g. Therefore, the correct option is option c) (52.875 kg).

The Index of Refraction of the champagne is approximately 1.00033.

To find the Index of Refraction of the champagne, we need to use the formula:
Index of Refraction = (sin i) / (sin r)
Where i is the angle of incidence (in this case, 30 degrees) and r is the angle of refraction (in this case, 18 degrees).
Plugging in these values, we get:
Index of Refraction = (sin 30) / (sin 18)
Index of Refraction = 1.00033
This means that the speed of light in champagne is about 1.00033 times slower than the speed of light in a vacuum.
Knowing the Index of Refraction is important in understanding how light behaves when it passes through different materials. The amount of refraction that occurs depends on the Index of Refraction of the material, as well as the angle of incidence.
