A 50.0-kg child stands at the rim of a merry-go-round of radius 2.70 m, rotating with an angular speed of 3.95 rad/s. What minimum coefficient of static friction is required

Answers

Answer 1

A 50.0-kg child stands at the rim of a merry-go-round of radius 2.70 m, rotating with an angular speed of 3.95 rad/s. Minimum coefficient of static friction is required 13.56.

To find the minimum coefficient of static friction required, we need to calculate the centrifugal force acting on the child and compare it to the force of friction.

The centrifugal force acting on the child is given by:

= Fc

= m * r * w^2

where

= m

= 50.0 kg (mass of child)

= r

= 2.70 m (radius of the merry-go-round)

= w

= 3.95 rad/s (angular velocity)

So, Fc = 50.0 kg * 2.70 m * (3.95 rad/s)^2

= 6629.775 N

The force of friction acting on the child is given by:

= Ff

= friction coefficient * normal force

where

friction coefficient = minimum coefficient of static friction required (unknown)

= normal force

= m * g

The normal force is equal to the weight of the child, which is

= m * g

= 50.0 kg * 9.8 m/s^2

= 490 N

So, Ff = friction coefficient * 490 N

To find the minimum coefficient of static friction, we need to set Ff equal to Fc and solve for the friction coefficient:

friction coefficient = Ff / N

friction coefficient = 6629.775 N / 490 N

= 13.56

So the minimum coefficient of static friction required is 13.56.

The kinetic energy of Flying pluff is 121 KJ.

What is Kinetic energy?

The energy that an object has as a result of motion is known as kinetic energy.  It is described as the effort required to move a mass-determined body from rest to the indicated velocity.

The body holds onto the kinetic energy it acquired during its acceleration until its speed changes. The body exerts the same amount of effort when slowing down from its current pace to a condition of rest.

Formally, a kinetic energy is any term that includes a derivative with respect to time in the Lagrangian of a system. According to classical physics, an object with mass m moving at a speed of v has kinetic energy equal to mv2.

A 2.6-mm-diameter sphere is charged to -4.4 nC. An electron fired directly at the sphere from far away comes to within 0.32 mm of the surface of the target before being reflected.
a. What was the electron's initial speed?
b. At what distance from the surface of the sphere is the electron's speed half of its initial value?
c. What is the acceleration of the electron at its turning point?

Answers

The correct answer to the given question is -6.944 * 10^-28 Joules

a. To find the electron's initial speed, we can use the conservation of energy. The initial kinetic energy of the electron must equal the final potential energy of the electron at its closest approach to the sphere.

Ki = 1/2 * me * v^2

v = sqrt(2Ki/me)

Ki = qe * V = (1.6 x 10^-19 C) * (-4.4 x 10^-9 C) = -6.944 x 10^-28 J

b. At the point where the speed of the electron is half of its initial value, the kinetic energy of the electron is half of its initial value. Therefore,

Ki/2 = 1/2 * me * (v/2)^2

we can solve for the distance from the surface of the sphere using the same equation as in part a, and substituting Ki/2 and v/2 for Ki and v respectively

c. The acceleration of the electron at its turning point can be found using the equation for centripetal acceleration:

a = v^2/r

where a is the acceleration, v is the speed of the electron, and r is the distance of the electron from the center of the sphere at its closest approach. We can use the value of v from part a and the distance from part b to find the acceleration.

How does gravitational force work?

The gravitational force, also known as gravity, pulls objects with mass in the same direction. We frequently think about the Earth's gravitational pull. This force is firmly holding your body in place. But every mass-bearing object attracts other mass-bearing objects toward it through gravity.

Using the formula of gravitational attraction

F = G× M₁M₂/d²

where G = 6.67 × 10⁻¹¹ Nm²Kg⁻²

M₁ = 8000Kg

M₂ = 1500 Kg

F =  6.67 × 10⁻¹¹ × 8000 × 1500 / (1.5)²

Answers

The time it takes for the ball to reach its maximum height is 745 milliseconds.

What is time?

Time is defined as a scalar quantity that describes the progression of events in the universe. It is often considered to be the fourth dimension of spacetime, along with the three dimensions of space. Time is closely related to the concepts of causality, or the relationship between cause and effect, and is considered to be a fundamental aspect of the physical universe.

To find the time it takes for the ball to reach its maximum height, we need to use the equation:

1/2 * a * t^2 + v * t + d = 0

where a is the acceleration due to gravity (-9.8 m/s^2), t is the time, v is the initial velocity (2.13 m/s), and d is the initial displacement (0 m, since the ball is thrown upward from the ground).

We know that the ball is thrown upward and reaches its maximum height, so it is subject to a constant acceleration due to gravity in the downward direction. Therefore, the acceleration is -9.8 m/s^2.

The time to reach the maximum height can be found by solving the above equation for t.

t = sqrt(-2*d/(a+v))

t = sqrt(-2*0/(-9.8+2.13))

t = sqrt(2*2.13/(9.8-2.13))

t = sqrt(4.26/7.67)

t = sqrt(0.555)

t = 0.745s

To get the time in milliseconds:

t = 0.745s * 1000ms/s = 745 ms

Therefore, the time it takes for the ball to reach its maximum height is 745 milliseconds.

Answers

Answer:

Magnitude of the change in momentum = 0.45kgms-1

Force exerted = 1.13N

Explanation:

The magnitude of the change in momentum of the fly can be calculated using the equation Δp = mv, where m is the mass of the fly and v is the velocity of the fly. In this case, the fly has a mass of 0.30g and an initial velocity of 1.5ms-1. Therefore, the change in momentum of the fly is

Δp = (0.30g) x (1.5ms-1) = 0.45kgms-1.

The average force exerted by the web on the fly can be calculated using the equation F = Δp/Δt, where F is the average force, Δp is the change in momentum of the fly, and Δt is the time taken for the fly to come to rest. In this case, the change in momentum of the fly is 0.45kgms-1 and the time taken for the fly to come to rest is 0.40s. Therefore, the average force exerted by the web on the fly is

F = (0.45kgms-1)/(0.40s) = 1.13N.

Does the effective thermal conductivity of an insulation system account for heat transfer by conduction alone

Answers

Yes, effective thermal conductivity of an insulation system accounts for heat transfer by conduction.

What do you mean by thermal conductivity?

Thermal conductivity is a property of a material that describes its ability to conduct heat. It is typically measured in units of watts per meter per kelvin (W/m·K). The thermal conductivity of a material is affected by various factors, such as temperature, pressure, and the presence of impurities or defects.

The effective thermal conductivity of an insulation system is a measure of its ability to resist heat transfer by conduction. It does not take into account other forms of heat transfer, such as convection or radiation.

The value of the thermal conductivity is typically measured by determining the rate of heat flow through a sample of the insulation material under specific conditions of temperature and pressure.

The lower the thermal conductivity, the better the insulation's ability to resist heat transfer by conduction.

Hence, effective thermal conductivity of an insulation system accounts for heat transfer.
