Calculation

In situations like this air resistance are usually been neglected thereby

making g= 9.81 m/

Bring out the given parameters from the question:

Initial Velocity () = 1000 m/s

Target distance (d) = 2000 m

Target height (h) =  800 m

Projection angle ∅ = ?

Horizontal distance = tcos ∅     .......................... Equation 1

where  = velocity in the X - direction

          t = Time taken

Vertical Distance = y =  t - g        ................... Equation 2

Where    = Velocity in the Y- direction

             t  = Time taken

= sin∅

Making time (t) subject of the formula in Equation 1

                   t = d/(cos ∅)

                     t =  =   =                 ...................Equation 3

substituting equation 3 into equation 2

Vertical Distance = d =   - g

                                 Vertical Distance = h = sin∅  - g

 Vertical Distance = h = dtan∅  

- g  Applying geometry

                              =  + 1

 Vertical Distance = h = d tan∅   - 2 g ( + 1)

              substituting the given parameters

              800 = 2000 tan ∅ - 2 (9.81)(  + 1)

             800 = 2000 tan ∅ - 19.6(  + 1)  Equation 4

Replacing tan ∅ = Q     .....................Equation 5

In order to get a quadratic equation that can be easily solve.

           800 = 2000 Q - 19.6 + 19.6

Rearranging 19.6 - 2000 Q + 780.4 = 0

                    = 101.6291

                      = 0.411

   Inserting the value of Q Into Equation 5

                tan ∅ = 101.63    or tan ∅ = 0.4114

Taking the Tan inverse of each value of Q

∅ = 89.44°     ∅ = 22.37°

What connection exists between hanging weight and centripetal force?

The centripetal force holding mass m1 in a horizontal circular orbit is equal to the weight of the hanging mass. When an object is moving at a certain speed, its weight exerts a force on it that causes the required centripetal acceleration; the track exerts no force on the object at all.

What forces are operating on a hanging object?

The downward pull of gravity and the upward tension force are the only two forces that the hanging mass (m2) is subject to. The centripetal acceleration of an item is independent of mass; as a result, the centripetal acceleration is unaffected by changes in mass.

5. if the air at 1000 mb is lifted to 700 mb, will it be colder or warmer than the surrounding air? does this represent a stable or an unstable condition? why?

Answers

When air at 1000 mb is lifted to 700 mb, it will be colder than the surrounding air.

This represents an unstable condition, as the air is not able to stay in its current state and is forced to move up and away from its original position. This creates a situation where the colder air is more dense and is more likely to sink back down towards its original position.

In an unstable condition, the air is constantly moving and shifting, making it difficult to predict what the weather conditions will be.

This condition is considered to be unstable because the air has become less dense than the air around it. As the air rises and cools, the air molecules condense and form clouds which can lead to the development of storms.

a boy is using a rope to pull a sled to the right. what are the directions of the tension force and the friction force on the sled respectively?

Answers

Answer:

Tension force: towards boy

Friction: away from boy

Explanation:

For this problem, assume that the boy is pulling the sled from left to right

Tension force:

The tension force is going to the right (towards the boy) because the boy is the one who is applying the tension force onto the sled for it to follow him.

Friction force:

In this case, there is kinetic friction between the ground and the sled. The kinetic friction is slowing down the sled, which is going to the right, therefore the direction of the friction force is pointing to the left (away from the boy)

3. 4. A horse runs with a velocity of 15 km/hr towards the north for 90 minutes. Determine the displacement of the horse.

Answers

Explanation:

A car travels north on the highway for 125 kilometers, then turns west for 75 kilometers, then makes a u-turn and travels south for 125 kilometers.

A. To determine the displacement of the car, you would need to calculate the final position of the car relative to its initial position. In this case, the car traveled north for 125 km, then west for 75 km, and then south for 125 km. This means the car ends up in the same place it started (125 km south of its starting point), so the displacement would be 0 km.

Anthony has 25 kilograms of sand, while Juan has 60 pounds of sand. To determine which of the two boys has the most amount of sand, we need to convert the weight of the sand from pounds to kilograms. 60 pounds is approximately 27.2 kilograms. So Juan has 27.2 kilograms of sand and Anthony has 25 kilograms of sand. Anthony has more sand.

A horse runs with a velocity of 15 km/hr towards the north for 90 minutes. To determine the displacement of the horse, you would need to calculate the distance traveled by the horse. You can use the formula: Displacement = velocity x time. In this case, the velocity is 15 km/hr and the time is 90 minutes (converted to hours). So, Displacement = 15 x (90/60) = 22.5 km towards the North.

Answers

The post collision velocity of the bawling ball is 2.35 m/sec, if the mass of the bowling ball is 88 kg and the mass of the pin is 0.95 kg.

The law of conservation of momentum will be used here to determine the post collision velocity of the ball.

Mass of the bowling ball, M₁ = 88 kg

Mass of the pin, M₂ = 0.95 kg

Before collision velocity of the ball, v₁ = 2.41 m/s

Let the post collision velocity of the ball = v₃

Pre-collision velocity of the pin, v₂ = 0

Post collision velocity of the pin, v₄ = 5.19 m/sec

By the law of conservation of momentum,

M₁v₁ + M₂v₂ = M₁v₃ + M₂v₄

This type of acceleration refers to a change in velocity that occurs at a constant rate over a period of time, in other words the acceleration is uniform.

For example, a car that is accelerating from a stop to a slow, steady speed would be experiencing constant acceleration. The speedometer in the car would show a gradual increase in speed, rather than a sudden jump.

This is different from non-uniform acceleration, where the rate of change in velocity is not constant. For example, a car accelerating rapidly from a stop to a high speed would be experiencing non-uniform acceleration, as the speedometer would show a rapid increase in speed.

Unpolarized light with intensity 350 W/m^2 passes first through a polarizing filter with its axis vertical, then through a second polarizing filter. It emerges from the second filter with intensity 126 W/m^2 what is the angle from vertical of the axis of the second polarizing filter?
Express your answer to two significant figures and include the appropriate units.

Answers

The angle from vertical of the axis of the second polarizing filter  unpolarized light with an intensity of 350 W/m² passes first through the polarizing filter with the vertical axis, then through the second polarizing filter and merging from the second filter with an intensity of 126 W/m² = 53°

The notions presented by Malus regarding the intensity of light must be used to answer this question.

According to the law of Malus, intensity is described as:

I' = [tex]\frac{1}{2}[/tex] I₀ cos²∅

The expression for the light's intensity is provided by after the first filter.

I = [tex]\frac{1}{2}[/tex] I₀

= [tex]\frac{1}{2}[/tex] (350 W/m²)

= 175 W/m²

Hence,

I' = [tex]\frac{1}{2}[/tex] I₀ cos²∅

cos²∅ = (2I' / I₀)

∅ = cos⁻¹ ([tex]\sqrt{\frac{(2)(126)}{350} }[/tex])

= 53°

Answers

This same statement expresses the fact that to the furthest item is 80 cm distant.

An object declaration class is what?

The combination of objects known as an object class may be characterised in by the traits that all of its members share. So all e-mail systems get some characteristics, generic e-mail, for instance, may be an object class.

The left item has travelled about 1/4 of the distance contrasted to the centre object, which means that if the centre object were to be pushed half as far as the right object, it would be pretty far away (20 cm). Consequently, add 4 to the centre object's distance.

It is 80 cm distant from the furthest item.

when using the oil immersion lens, what four procedures can be implemented to achieve the maximum resolution?

Answers

When using an oil immersion lens, four procedures can be implemented to achieve maximum resolution: Using a high-quality oil immersion objective lens, Keeping the objective lens clean, Proper focus, Proper oil matching.

What are the requirements to practice the procedures?

1.Using a high-quality oil immersion objective lens: The oil immersion objective lens is the most critical component in achieving high resolution. Using a high-quality, high numerical aperture lens will ensure that the resolution is maximized.

2.Proper oil matching: The type of oil used in the immersion lens needs to have the same refractive index as the cover glass of the microscope slide to achieve maximum resolution.

3.Keeping the objective lens clean: Any dust or debris on the lens can affect the resolution. Regular cleaning of the lens with appropriate solvents will help to maintain maximum resolution.

4.Proper focus: The microscope stage needs to be adjusted so that the objective lens is in the correct position, i.e., in focus, to achieve maximum resolution. This can be done by using the fine focus knob or a focus motor.

By implementing these procedures, the maximum resolution can be achieved with an oil immersion lens.

Additionally, using the oil immersion lens at the highest possible magnification while keeping the sample well illuminated will also help to achieve the best resolution.

If the solar system were the size of your campus, how far away would the nearest star be?.

Answers

The nearest star, Proxima Centauri, would be about 4.22 light-years away if the solar system were the size of a campus.

The scale of the solar system is vast and difficult to imagine. To give a sense of perspective, if the solar system were scaled down to the size of a campus, with the sun at the center of the campus, the nearest star, Proxima Centauri, would be located about 4.22 light-years away or 24.9 trillion miles. That would be equivalent to traveling around the world over 1,174,000 times. This distance is extremely large and it is hard to comprehend but this gives us an idea of how vast and empty space is. Even the closest stars to our solar system are incredibly distant, and it's hard to imagine just how far away the more distant stars and galaxies are.
