Hi there!

Assuming the rod is pulled back 90° (π/2 radians), we can use angular kinematics to solve.

Using the equation:

[tex]\omega_f^2= \omega_i^2 + 2\alpha \theta[/tex]

[tex]\omega_f[/tex] = final angular velocity (? rad/sec)

[tex]\omega_i[/tex] = initial angular velocity (0 rad/sec)

[tex]\alpha[/tex] = angular acceleration (rad/sec², must solve for)

[tex]\theta[/tex] = angular displacement (π/2 rad)

Recall Newton Second Law's rotational equivalent:
[tex]\Sigma \tau = I\alpha[/tex]

τ = Torque (Nm)

I = Moment of inertia (kgm²)
α = angular acceleration (rad/sec²)

Setting the pivot point at the end, and knowing that the force of gravity works at an object's center of mass (1.5m from the rod's end), we can solve for the angular acceleration.

[tex]\tau= F \times r\\\\\tau = W \times r = 10(9.8) * 1.5 = 147 Nm[/tex]

Now, solve for the moment of inertia given I = 1/3ML² at one of its ends:
[tex]I = \frac{1}{3}(10)(3^2) = 30 kgm^2[/tex]

Solve for the angular acceleration:
[tex]147 = 30\alpha\\\\\alpha = 4.9 \frac{rad}{sec^2}[/tex]

Now, we can use the kinematic equation to solve.

[tex]\omega_f^2 = 0 + 2(4.9)(\frac{\pi}{2}})\\\\\omega_f = \sqrt{2(4.9)(\frac{\pi}{2})} = \boxed{3.923 \frac{rad}{sec}}[/tex]

The wavelength of the  radio wave in water is 222nm

The relationship between the refractive index  wavelengths in a vacuum and in water is given by:

n = λ1/λ2

So,

let λ1 be the wavelength of light in a vacuum

λ2 be the wavelength of light in water.

nwater = 1.33

Plugging in values, we have

n = λ1/λ2

1.33 =295 m /λ2

λ2 = 295 m/1.33

 = 221.80nm

 ≈222nm

Therefore the wavelength of radio wave in water is 222mn.

We have that the magnitude of the magnetic field is determined by the amount of current produced.

Generally,  the magnetic field strength is called the tesla This  is measured as one Newton per ampere-meter.

Electromagnet is a  magnet where the magnetic field is created by an electric current,

Therefore the magnitude of the magnetic field is determined by the amount of current produced

The potential energy of the fighter jet of mass 'm' at a height of 10000 meters will be 98000m.

The energy of the body due to its position is called potential energy. If a body of mass 'm' is at height 'h' above the ground, then its potential energy with respect to earth will be -

E[P] = mgh

Given is a fighter jet traveling at a height of 10,000 meters.

The potential energy of a body at height 'h' above the ground is given by-

E[P] = mgh

where -

m is the mass of body

g is the acceleration due to gravity

Assume that the mass of jet fighter is 'm'. Then its potential energy will be -

E = mgh

E = m x 9.8 x 10000

E = 98000m

Therefore, the potential energy of the fighter jet of mass 'm' at a height of 10000 meters will be 98000m.

Explanation:

The work the truck engine did during the 2 hour period is 8.1 × 10⁹ J

From the question, we are to determine how much work the truck engine did

Work is given by the formula

Work = Force × Distance

First, we will determine the distance traveled by truck

From the formula,

Distance = Speed × Time

From the given information

Speed = 45 m/s

Time = 2 hours = 2×60×60 = 7200 secs

Then,

Distance = 45 × 7200

Distance = 324000 m

Now, for the work done

Work = Force × Distance

From the given information,

Force = 25 kN = 25000 N

Therefore,

Work = 25000 × 324000

Work = 8.1 × 10⁹ J

Hence, the work the truck engine did during the 2 hour period is 8.1 × 10⁹ J

Answer:

1 g/cm³

Explanation:

1 kg = 1000 g

1 cm = 0.01 of a meter

1 m³ = 100 cm * 100 cm * 100 cm = 1,000,000 cm

1,000 kg / 1 * 1000 g / 1 kg

^ divided by 1,000,000 cm

1,000,000 divided by 1,000,000 = 1 g/cm³

While alloys are melted mixtures of two or more metals, true metals are unadulterated components. Due to their tendency to be shinier, heavier, and harder than the majority of materials, as well as the fact that they are great heat- and electricity-conductors, metals, and alloys are simple to differentiate from nonmetals.

As a compound or a solution, an alloy is a metallic material made up of two or more elements. Although carbon, a nonmetal, is a crucial component of steel, alloys typically contain metals as their own constituents.

Typically, the mixture of elements is melted to create an alloy. In very early periods, the value of alloys was discovered; brass (copper and zinc) and bronze (copper and tin) were particularly significant.

Answer:

Explanation:

I typed this into Acellus and it was correct.

Answer:

We know that 1 meter = 100 centimeters, and 1 foot = 12 inches.

So  (1,609 meters) x (100 centimeters/meter)  =  (5,280 feet) x (12 inches/foot)

The second fraction on each side of the equation is equal to ' 1 ', because

the numerator is equal to the denominator, so sticking it in there doesn't

change the value of that side of the equation.  But now we can cancel some

units,and wind up with the units we need.

  (1,609 meters) x (100 centimeters/meter)  =  (5,280 feet) x (12 inches/foot)

        (1,609 x100) centimeters  =  (5,280 x 12) inches

            160,900 centimeters  =  63,360 inches

Divide each side by  63,360 :        2.54 centimeters =  1 inch
