ice crystals that form by accretion are fairly large. explain why they fall slowly.

Answers

Ice crystals that form by accretion are fairly large, they fall slowly because of there high surface area to volume ratio, which cause high air resistance.

Ice crystals that form by accretion are large and have a high surface area to volume ratio. This high surface area causes more air resistance, which slows their fall. The larger the surface area, the more air resistance there is, and the slower the crystals fall. Additionally, the shape of the crystals can also affect their fall speed, with more irregular shapes experiencing more air resistance and thus falling slower. Ice crystals are the building blocks of snowflakes and have a well-defined and ordered internal structure. The structure of an ice crystal depends on the conditions under which it forms, such as temperature and humidity. At very cold temperatures, the crystals are usually simple hexagonal structures, while more complex branching structures can form at warmer temperatures.

A ball is attached to the end of a string. It is swung in a vertical circle of radius 0.90 m. What is the minimum velocity that the ball must have to make it around the circle?

Answers

Moving in a vertical circle If the distance is calculated using a fixed point, it will be the same everywhere. The ball needs to travel around the circle at a minimum speed of 44.1 m/s.

What is called velocity?

The vectorial expression of velocity is the movement in space-time of an object or particle. The recognised unit of velocity magnitude is the metre per second (m/s) (also known as speed). The rate of speed can also be expressed in centimetres per second (cm/s). The pace at which an object's location changes as seen from a certain angle and as stated by a specific time unit (for example, 60 km/h northbound) is measured by its velocity, which is the direction in which it is travelling.

What is velocity in physics?

As a physical vector quantity, velocity must have a specified magnitude and direction. Speed is a coherent derived unit whose quantity is measured in metres per second (m/s or ms1) in the SI. Speed is the scalar absolute value (magnitude) of velocity (metric system). A vector is "5 metres per secon.

The vertical circle has a radius of 0.90 metres.

As the ball rotates vertically and continuously in a circular motion. As a result, the ball will move at the same speed at each point.

Consequently, the centripetal force ought to be constant at each location, that is,

mv2/R

Here, m stands for mass. R is the radius, and v is the speed.

The tension operating on the ball (towards the centre) and the gravitational force acting on it counteract this centripetal force. Thus,

mv2/R=T+mg

The tension should be zero for the minimal velocity. Thus,

mv2/R=mg

Simplify it as,

V2/R=g

V=√Rg

Assume that V is the initial velocity.

1/2mv2=mg(2R)+1/2m(√(gR^2 )

V=√5gR

G's squared value is 9.8 m/s. The ball must therefore move at a minimal speed in order to complete the circle:

What will be the acceleration, if a vehicle started from rest and its velocity reached 20 m/s after 5 second? Calculate. Ans: 4m/s (2)​

Answers

Answer: 4m/s2 ✅

Explanation: A vehicle started from rest and its velocity reached 20m/s after 5 seconds. To calculate the acceleration, we can use the formula: acceleration = (change in velocity) / (change in time).

The change in velocity is 20m/s - 0m/s = 20m/s (the final velocity minus the initial velocity)

The change in time is 5 seconds (the time it takes for the velocity to change)

So the acceleration of the vehicle is (20m/s) / (5s) = 4m/s2✅

Answer: The acceleration of the car starting from rest is 4 m/s^2✅

A solid cube of mass 87 kg and edge length 0.95 m rests on a horizontal floor as shown below. A person then pushes on the upper edge of the cube with a horizontal force of magnitude F. At what value of F will the cube start to tip? Assume the frictional force from the floor is large enough to prevent the cube from sliding.

Answers

The force required to tip the cube is equal to the coefficient of static friction times the weight of the cube.

fx=μs * 87 kg * 9.8 m/s^2

What is the force required to tip the cube?

Generally, The cube will start to tip when the net torque about the point of contact between the cube and the floor is equal to zero. The torque is given by:

torque = force x distance from axis of rotation

The distance from the axis of rotation is half the edge length of the cube (0.475m), and the force is the force applied by the person (). Therefore, the torque is:

torque = fx x 0.475

For the cube to tip, the torque due to the person's force must be greater than the maximum torque the friction can provide, which is the friction force times the distance from the axis of rotation.

The maximum torque provided by friction is:

friction torque = friction force x 0.475

Since the friction force is equal to the normal force (mg) multiplied by the coefficient of static friction (μs), the maximum torque provided by friction is:

friction torque = μs * mg * 0.475

where m is the mass of the cube, g is the acceleration due to gravity and μs is the coefficient of static friction between the cube and the floor.

So, we can find the force needed to tip the cube by equating the torque due to the force with that of the friction torque.

Fx*0.475 = μs * m * g * 0.475

Fx= μs * m * g

Fx= μs * 87 kg * 9.8 m/s^2

This question discusses circular motion. Circular motion is the motion of an object that forms a circular path around a fixed point. An object moving in a circle needs a force that always deflects it toward the center of the circular path. This force is called the centripetal force.

Horizontal equilibrium T sinθ = m x v²/r

r = D/2 = 10.8/2 = 5.4 m

From the above two equations, mg tanθ = m x v²/r

but from the figure

r = L sinθ + 5.4 m

r = (2.85 x sin38.2 + 5.4)

r = (2.85 x 0.6184 + 5.4) = 7.1 m

So,

v² = g x tanθ x r

v² = 9.8 x tan38.2 x 7.1

v² = 9.8 x 0.78 x 7.1

v  = √54.27

C The system has 2.655 kJ of work done by the surroundings.

D The system performs 2.655 kJ of work on the surroundings.

Answers

The work done by the system is -2.655KJ. This states that the system performs 2.655KJ of work on the surroundings. Thus, the correct option is D.

What is work done?

Work done is defined as the product of force and the distance over which the force is applied on the object. Work is done when a force is applied to an object and the object experiences motion through a distance.

Given that the work is done on the surrounding, i.e., the work is done by the system and the heat is absorbed by the system.

Therefore,

ΔU = -5.155KJ

q = 2500J = 2.5KJ

Now from first law of thermodynamics,

ΔU = q + w

-5.155 = 2.500 + w = -2.655KJ

w = -2.655KJ

Hence the work done is -2.655kJ.

We are aware of what the circle's area is.

A =π r²

Compare equation with regard to time t.

dA/dt = 2π r dr/dt

while dr/ dt = 0. 2m/ sec

so

dA/dt = 0.8 π r

The circle's circumference is also known to be,

C= 2π r

60π = 2π r

r = 30

Now put the value r in equation

dA/dt = 0.8 π r

dA/dt = 0.8 π 30

dA/dt = 24 π

Your question is incomplete but most probably your full question was

We have long known about the effects of stereotyping. Thats why we have been fighting to put an end to these stereotypes. Now, reality television is harming our progress. One researcher at Syracuse University, Sherri Williams, found that people on reality shows were chosen based on how well they fit certain stereotypes. During the show, they were encouraged to play up these stereotypes as much as possible. In this way, the show helped to strengthen stereotypes about different types of people.Which sentence can be added to the paragraph as supporting evidence for its main idea?A.
