F₁ = 6.59 N  (South)

F₂ = 8 507.74 N (toward the ground)

F₃ = 8 507.74 N ( up away from the ground)

F₄ = 147.43 (North)

F₅ = 22.82 (South)

__________

Forces F₂ and F₃ balance each other.

Resultant force:

R = F₄ - F₁ - F₅

R = 147.73 - 6.59 - 22.81 = 118.33 N

The breaking force, given that the truck reduces it speed from 12 m/s to 6 m/s over a distance of 40 m is -2700 N

We'll begin by obtaining the deceleration of the truck. Details below:

v² = u² + 2as

6² = 12² + (2 × a × 40)

36 = 144 + 80a

Collect like terms

36 - 144 = 80a

-108 = 80

Divide both side by 80

a = -108 / 80

a = -1.35 m/s²

Finally, we shall determine the breaking force. Details below:

Force = mass × deceleration

Breaking force = 2000 × -1.35

Breaking force = -2700 N

Thus, the breaking force is -2700 N

Explanation:

its been awhile since I've worked on Newton's first law

Answer:

80.08 km/h

Explanation:

Given that Black Panther ran 567.6 km to the east in 23 hours

Velocity = distance covered/time

Substitute the distance covered and time into the formula

Velocity = 567.6/23

Velocity = 24.68 km/h

then turned around and ran 221.8 km to the west in 1.2 hours.

Velocity = 221.8/1.2

Velocity = 184.83 km/h

What was his average velocity during the trip in km/h ?

Average velocity = (V + U)/2

Since the two velocity are opposite to each other, the average velocity will be:

Average velocity = (-24.68 + 184.83)/2

Average velocity = 160.15/2

Average velocity = 80.08 km/h

Therefore, his average velocity during the trip is 80.08 km/h

A solid uniform sphere of mass 1.85 kg and diameter 45.0 cm spins about an axle through its center. starting with an angular velocity of 2.50 rev/s, it stops after turning through 17.2 rev with uniform acceleration. the net torque acting on this sphere as it is slowing down is closest to - 1.22 × \(10^{-4}\) Nm.

We can use the rotational kinematic equations to solve this problem. The equation that relates the final angular velocity, initial angular velocity, angular acceleration, and the displacement is

\(wf^{2}\) = \(wi^{2}\) + 2αθ

Where ωf is the final angular velocity, ωi is the initial angular velocity, α is the angular acceleration, and θ is the displacement.

We can solve for the angular acceleration, α

α = (\(wf^{2}\) - \(wi^{2}\)) / 2θ

We know that the initial angular velocity is ωi = 2.50 rev/s, the final angular velocity is ωf = 0 (since the sphere stops), and the displacement is θ = 17.2 rev. We can convert the units of rev to radians

θ = 17.2 rev × 2π rad/rev = 108.14 rad

Substituting these values into the equation for α, we get

α = (0 - \((2.50 rev/s)^{2}\)) / (2 × 108.14 rad)

α = -0.0053 rad/\(s^{2}\)

The moment of inertia of a solid uniform sphere about an axis through its center is given by

I = (2/5)M\(R^{2}\)

Where M is the mass of the sphere and R is the radius of the sphere. We know that the diameter of the sphere is 45.0 cm, so the radius is R = 22.5 cm = 0.225 m. Substituting the given values, we get

I = (2/5)(1.85 kg)\((0.225m)^{2}\)

I = 0.023 kg\(m^{2}\)

The net torque acting on the sphere can be calculated using Newton's second law for rotation

τ = Iα

Substituting the values we obtained for I and α, we get

τ = (0.023  kg\(m^{2}\))(-0.0053 rad/\(s^{2}\))

τ = - 1.22 × \(10^{-4}\) Nm

Therefore, the net torque acting on the sphere as it is slowing down is closest to - 1.22 × \(10^{-4}\) Nm (in the negative direction).

This claim violates the Second law of thermodynamics.

The second law of thermodynamics states that each transformation releases some energy in the form of heat, hence it is impossible to create a car that can turn all of the potential energy in gasoline into kinetic motion without any waste.

When a car is running on gasoline, some of the energy it produces is lost to heat within and around the engine, which increases entropy. While some of the thermal energy generated by burning gasoline is utilised to move the automobile during internal combustion, the majority of the thermal energy is used to heat the engine and the exhaust gases, which do not drive the car. Therefore, an automobile that is 100% efficient cannot be created.

To determine the greatest distance you can be from the base camp at the end of the third displacement, regardless of direction, we need more specific information about the magnitudes and directions of the displacements.

Displacement is a vector quantity that has both magnitude and direction. The distance covered during multiple displacements depends on the individual magnitudes and directions of each displacement. Without specific values, it is not possible to determine the exact greatest distance from the base camp.

If you provide the magnitudes and directions of the three displacements, I can help you calculate the total distance and determine the maximum possible distance from the base camp at the end of the third displacement.

The average person's vertical jump on the Moon would be 0.65 m.

The gravitational acceleration near the surface of the Moon is 1.62 m/s2, which is about one sixth the gravitational acceleration on Earth.

As a result, an average person's vertical jump on the Moon would be less than on Earth.

To calculate the vertical jump on the Moon, we need to use the formula h = 1/2 x g x t2.

This equation is used to calculate the height h (in meters) that an object will reach when thrown into the air, given the gravitational acceleration g (in m/s2) and the time t (in seconds) it takes to reach the peak of the jump.

Since the gravitational acceleration on the Moon is 1.62 m/s2, and the time taken to reach the peak of the jump is the same (assume 0.5 s), then h = 0.5 x 1.62 x (0.5)2, which is 0.65 m.

Therefore, an average person's vertical jump on the Moon would be 0.65 m.

Answer: False

Explanation: The sun is one of earths primary energy sources. Without the sun, all animals, plants, humans would die. The sun's energy provides warmth for humans and plants and animals cannot grow without the sun.

The statement "Energy from the sun tends to affect only a small part of Earth's system" is false.

The sun emits several forms of energy, including visible light, ultraviolet radiation, infrared radiation, and X-rays. Of these, visible light is the most abundant form of energy that reaches the Earth's surface.

The visible light from the sun provides the energy that drives the Earth's climate and weather patterns, powers photosynthesis in plants and algae, and is responsible for the colors we see in the world around us.

In addition to visible light, the sun also emits ultraviolet (UV) radiation. Some of this UV radiation is absorbed by the Earth's atmosphere, which helps to protect us from its harmful effects, but some of it reaches the Earth's surface and can cause skin damage and other health problems.

The sun also emits infrared radiation, which is responsible for heating the Earth's surface and atmosphere. This heat is important for the Earth's climate and weather patterns and is also used to generate electricity in solar power plants. The energy from the sun is essential for life on Earth and has a major impact on virtually every aspect of the Earth's system.

Here in the Question,

Energy from the sun has a major impact on the entire Earth system, from the atmosphere to the oceans to the land surface. The energy from the sun drives the Earth's climate and weather patterns, it powers the hydrologic cycle and drives ocean currents, and it provides the energy for photosynthesis, which is the basis of the Earth's food chain.

The energy from the sun that reaches the Earth's surface is also responsible for many physical and chemical processes that occur in the Earth's crust and upper mantle. For example, the energy from the sun powers the movement of tectonic plates, which leads to earthquakes, volcanic eruptions, and the formation of mountains.

The energy from the sun affects virtually every aspect of the Earth's system, from the smallest microorganisms to the largest geological features.

Therefore, the statement "Energy from the sun tends to affect only a small part of Earth's system" is false.

The number of sets of measures that a within-subjects F-test will accommodate depends on the specific design and factors involved in the study.

The within-subjects F-test, also known as repeated measures ANOVA (Analysis of Variance), is used to analyze the effects of one or more independent variables on a dependent variable measured on the same subjects over multiple conditions or time points. In a within-subjects design, each participant or subject undergoes all levels or conditions of the independent variable(s). The number of sets of measures is determined by the number of levels or conditions of the independent variable(s) being studied. For example, if there are two independent variables, each with three levels, and all participants are measured in each combination of levels, then there would be six sets of measures (2 * 3 = 6).
