So the force on the top of the ride will be 452 N

Since we  are given the  mas which is 56.0 kg  and the time taken will be 4.20 s and  the diameter is  16m,  so the radius of the rotating ring will be 8 m(d/2)

So the formula we are referring to for calculating the centrifugal for

Fc = mω²R, where r is the radius of the ring m w  is the angular velocity and  m is the mass of  the object

since, ω = 2πf

=>ω = 2π( 1/t )

So the centrifugal force will be = m(2π*(1/t ))²R

=>56.0 *(2*3.148(1/4.20))²*8

=>1000.80903086

So the force on the top will be  

=centrifugal force  - mg

=>F=1000.80- (56*9.8)

Answer:

Height, h = 8.163 meters

Explanation:

Given the following data;

Mass = 10kg

Potential energy = 800J

We know that acceleration due to gravity is equal to 9.8m/s²

To find the height of the hill;

Potential energy can be defined as an energy possessed by an object or body due to its position.

Mathematically, potential energy is given by the formula;

\( P.E = mgh\)

Where,

P.E represents potential energy measured in Joules.

m represents the mass of an object.

g represents acceleration due to gravity measured in meters per seconds square.

h represents the height measured in meters.

Substituting into the equation, we have;

800 = 10*9.8*h

800 = 98h

Height, h = 800/98

Height, h = 8.163 meters

The acceleration of the box is 0.025 m/s²

We'll begin by calculating the the frictional force

Coefficient of kinetic friction (μ) = 0.21

Mass (m) = 8 Kg

Acceleration due to gravity (g) = 10 m/s²

Normal reaction (N) = mg = 8 × 10 = 80 N

Fբ = μN

Fբ = 0.21 × 80

Frictional force (Fբ) = 16.8 N

Force (F) = 17 N

Fₙ = F – Fբ

Fₙ = 17 – 16.8

Mass (m) = 8 Kg

Net force (Fₙ) = 0.2 N

a = Fₙ / m

a = 0.2 / 8

Therefore, the acceleration of the box is 0.025 m/s²

In Stratosphere layer  the Concorde cruise, the troposphere wouldn't carry the Concorde. The temperature increases with weight in stratosphere.

The stratosphere layer is one of the layers of the atmosphere on Earth. In an upward direction, it is the second layer of the atmosphere. Right under the stratosphere is the lowest layer, the troposphere. The mesosphere is the stratosphere's higher-level neighbour. At mid-latitudes, the stratosphere's bottom is located around 10 kilometres (6.2 miles, or about 33,000 feet) above the surface. A 50 km altitude marks the stratosphere's highest point (31 miles). With latitude and seasonal changes, the height of the lower stratosphere varies. When compared to the poles, the lower boundary of the stratosphere can range from 7 km (4 miles) to 20 km (12 miles), or a height of 65,000 feet, close to the equator.

Top-down processing is used when we interpret new stimuli in light of our prior knowledge. The image focused on each retina is from a slightly different angle because we have two eyes in two separate places. Binocular disparity is the term for this phenomenon.

There are two main approaches to making meaning of stimuli: bottom-up and top-down. Bottom-up processing occurs when we let the data itself, free of any preconceived ideas, shape our perception.

In top-down processing, we interpret what we perceive by drawing on our prior knowledge and expectations.

According to the theory of "top-down processing," our brains first build a notion of the overall picture based on prior knowledge before breaking it down into more detailed information. We use our perceptual set—past experiences, expectations, and emotions—to interpret the world around us.

Therefore, when we process new stimuli based on our past experiences, we are using top-down processing.

The three options are 1,3 and 5 Moving the balls closer together. The distance decreases and forces increase.

The gravitational force ia s type of force has the ability attracts any two objects with mass. Gravitational force tries to pull two masses towards each other.

The value of the gravitational force is given by;

\(F_g=\frac{ Gm_ 1m_2}{r^2}\)

It is observed that the gravitational force is directly propotional to the product of mass and inversly propotional to the square of the distance between them.

So, the correct options are :

(1) Moving the balls closer together. The distance decreases and forces increase.

(3) Wrapping the soccer ball in layers of duct tape will also increase force because the mass will increase.

Answer: For what objects? And what data?

Explanation:

Given data:

* The mass of the cannonball is m_1 = 49 kg.

* The initial velocity of the cannonball is u_1 = 0 m/s.

* The final velocity of the cannonball is v_1 = 134 m/s.

* The mass of the boat and pirate is m_2 = 356 kg.

* The initial velocity of the boat and pirate is u_2 = 0 m/s.

Solution:

According to the law of conservation of momentum, the net momentum of the system in the initial state is equal to the net momentum of the system in the final state.

Thus,

Substituting the known values,

By simplifying,

Here, the negative sign indicates the motion of the boat and pirate is opposite to the direction of the cannonball.

Thus, the velocity of the boat and pirate after the cannonball fired is -18.44 meters per second.

Dennis, 60 feet in 0.5 seconds is the average speed of a pitcher's fastball. So, the correct option is (A).

Average speed is defined as the total distance covered by the object in a particular time interval. Average speed is a scalar quantity which is represented by the magnitude and not the direction.

The formula for average speed is found by calculating the ratio of the total distance traveled by the body to the time taken to cover that distance which is expressed as:

Average speed= Total distance travelled/ Time taken

The unit of the average speed is meter/second.

In the above given information, the pitcher's fastball average speed of Dennis is 120

Answer:

96.3%

Explanation:

Efficiency = Work input/Work output * 100%

Work done = Force * distance\

Work done by the engine is the work output = 700 * 0.55

Work output = 423.5Nm

Work done by you is the work input = 35.7*11.43

Work input = 408.051Nm

Efficiency = 408.051/423.5 * 100

Efficiency = 0.963 * 100

Efficiency = 96.3%

Hence the efficiency of the pulley system is 96.3%

In order to experiment how the mass of an object impacts how fast the object falls to earth due to gravity by dropping balls of different mass to the ground ,  three variables in the experiment that the students would need to keep constant are acceleration, gravity as well as velocity.

When something falls, gravity is the cause of the fall. That object experiences a force, which causes it to accelerate, increasing its fall velocity. Gravitational force—the force the Earth exerts on objects—is a sort of acceleration. Everything feels the exact same amount of pull from Earth. Everything accelerates in the same manner toward the Earth. Even though objects of different masses experience different amounts of force, they all accelerate at the same rate on Earth. The amount of material multiplied by the rate at which it is being drawn toward the Earth or any other planet or moon produces weight, which is the force acting on the mass as a result of gravity.

If things of different masses are dropped from the same height, they will still impact the ground at the same time because Earth provides everything the exact same acceleration.

Everyone has dropped a marble and a feather at the same moment and they all landed on the floor at various times, so when you tell it for the first time, no one will believe you. The reason for this is because air is pushing against the item in the direction that the Earth is tugging, not variations in acceleration, which are constant on Earth. Air resistance is what generates this force.

A piece of paper, for instance, has a lot of surface area that is exposed to the air resistance if it is dropped horizontally. However, there is less area exposed to the air resistance if the paper is dropped vertically and on the thin side. This indicates that the paper will experience the same pull from the Earth and less push from the air in that position. The floor won't be struck simultaneously by two pieces of paper of equal mass dropped from the same height but with one in the horizontal position and the other in the vertical position.
