here Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water. These negative impacts can affect human behavior and can prompt mass migrations or battles over clean water.

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.

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]

Answer:

equator

Explanation:

The diameter of earth is largest when measured around the equator, due to the equatorial bulge.

The equatorial bulge is a phenomenon caused by the Earth's diameter being wider in the Equator.

A straight line with its endpoints located on the edge of the circle and its center is used to calculate the diameter of a circle. Latitudes like the equator and the Arctic Circle have diameters that can be calculated by scientists.

The Equator is the place on Earth where it is the broadest. At the equator, the circumference of the Earth is 40,075 km.

The force of attraction between all masses in the universe; especially the attraction of the earth's mass for bodies near its surface.

Answer:

A complete vibration is called a "period".

Starting at 0, the particle would move to +A, back to zero, to -A and back to zero to complete one cycle of a vibration

Answer:

a ) Its resistance

Explanation:

It depends on current and resistance

Example: Increasing the tension in A string causes the speed of waves on the string to increase. Since the wavelengths of the standing waves remains constant, this results in a larger frequency of oscillations in the string, which we percieve as a higher pitch when the string vibrates the air.

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
