The correct question is

A block of mass 0.10 kg is attached and secured to one end of a spring with spring constant 50. The other end of the spring is secured to a wall. The block is pushed against the spring, which compresses the spring to a position of z=-0.04 m. When uncompressed, the end of the spring that is attached to the block is at a position of = 0.00 m. The block-spring system is then released from rest, and the block travels along a horizontal, rough track. A motion sensor is placed so that it measures the velocity of the object as it slides along the track. A graph of total mechanical energy of the block-spring system as a function of position is shown. Which of the following statements about the block-spring system are true? Select two answers.

A-The force exerted on the block by the spring at z=-0.02 m is 1 N.

B-The block has maximum speed at 0.00 m.

D-The work done by friction as the block travels from -0.04 m to -0.02 m is 0.01 J.

Particle 1 and Particle 2 these two particles have the same centripetal force.

correct option: (A) and (B)

Any force that changes the direction of motion toward the center of a circular motion is known as a centripetal force. The part of the force that produces the centripetal force is the part that is perpendicular to the velocity. Due to Earth's permanent axis of rotation, the direction of centrifugal force is always outward and away from the axis, which is the opposite of the direction of gravity at the equator and zero in the poles.

The direction of centrifugal force is always outward and away from the axis because the Earth revolves around a fixed axis. At the equator, it is therefore the opposite of the direction of gravity; at the poles, it is zero.

Centripetal acceleration is given by: a = v²/r

For particle 1: a₁ = v²/r

For particle 2: a₂ = (2v)²/2r = 2v²/r

For particle 3: a₃ = (v/2)²/r = v²/4r

For particle 4: a₄ = (2v)²/3r = 4v²/3r

centripetal force (F) = ma

Thus,

F₁ = = ma = mv²/r

F₂ = (m/2)a₂ = mv²/r

F₃ = 2ma₃ = 2mv²/4r = mv²/2r

F₄ = m4v²/3r = 4/3mv²/r

a) electric field will be zero at (2.414 × d) distance from weaker charge Q, and at (3.414 × d) distance from the stronger charge 2Q

b) electric field will be zero at '0.414d' distance from weaker charge Q, and at '0.586d' distance from the stronger charge 2Q.

When charge exists in any form, an electric field is linked with each point in space. E, often known as electric field strength, electric field intensity, or just the electric field, is a mathematical constant that expresses the strength and direction of an electric field.

a)

Electric field is given by:

Assuming ₁ = Q, q₂ = 2Q, and suppose q₁ is at origin and q₂ is at x = +d

Now suppose at point P, distance x = - r electric field is zero, then

E(net) = E₁ - E₂ = 0

E₁ = E₂

kq₁/r₁² = kq₂/r₂²

r₁ = distance between q₁ and P = r

r₂ = distance between q₂ and P = d + r

Using above values:

q₁/r₁² = q₂/r₂²

Q/r² = (2Q)/(d + r)²

1/r² = 2/(d + r)²

(d + r)/r = √2

(d + r) = r × √2

r = d/((√2) - 1) = 2.414 × d

So. electric field will be zero at (2.414 × d) distance from weaker charge Q, and at (3.414 × d) distance from the stronger charge 2Q.

b)

Electric field is given by:

E = kq/R²

We know that the direction of the electric field will be away from the charge when the charge is (+)ve and towards the charge when the charge is (-)ve. Since q₁ and q₂ have the same sign in the example, the electric field between the charges will be zero.

Assuming q₁ = Q, q₂  = 2Q, and suppose q₁ is at origin and q₂ is at x = +d

Now suppose at point P, distance x = r from origin electric field is zero, then

E(net) = E₁ - E₂ = 0

E₁ = E₂

kq₁/r₁² = kq₂/r₂²

r₁ = distance between q₁ and P = r

r₂ = distance between q₂ and P = d - r

Using above values:

q₁/r₁² = q₂/r₂²

Q/r² = (2Q)/(d - r)²

1/r² = 2/(d - r)²

(d - r)/r = √2

d - r = r ×√2

r = d/((√2) + 1) = 0.414d

So, electric field will be zero at '0.414d' distance from weaker charge Q, and at '0.586d' distance from the stronger charge 2Q.

A free-body diagram of the block on the frictional part of the surface would show the force of friction acting in the opposite direction to the velocity of the block, and the force of gravity acting downward.

Using conservation of energy, the speed of the block at the base of the ramp can be found by setting the initial kinetic energy of the block (1/245^2) equal to the final kinetic energy of the block (1/2mv^2) and solving for v. v = sqrt((1/245^2)/(1/2*m)) where m is the mass of the block.

Using conservation of energy, the maximum vertical height H of the block on the ramp can be found by setting the initial potential energy of the block (mgH) equal to the final kinetic energy of the block (1/2mv^2) and solving for H. H = (1/2mv^2)/(m*g)

a) The total impulse given to the mass on the spring (mass A) during the brief collision is the product of the force exerted on the mass by the block and the time duration of the collision.

b) The speed of the mass on the spring (mass A) immediately after the collision can be determined using the conservation of momentum.

c) The velocity of the block immediately after the collision can also be determined using the conservation of momentum.

d) The spring constant can be determined by using the equation k = (2*F)/x, where F is the force exerted on the spring and x is the compression of the spring.

To find the horizontal range of the block from the end of the ramp, we can use the equations for horizontal and vertical motion of a projectile, with the angle of launch being 30 degrees, the initial speed being 6 m/s, and the final vertical position being 1m above the end of the ramp.

The negative charge on one of the identical spheres in a pair of conducting, fixed, and attracted to each other by an electrostatic force spheres is -1.00*10^-6 C. We can calculate this using Coulomb's law.

We can begin by using Coulomb's law, which states that the electrostatic force between two charges is proportional to the product of the charges and inversely proportional to the square of the distance between them.

Coulomb's law can be mathematically written as:

F = k * (q1 * q2) / r^2

where F is the force, k is the Coulomb constant, q1 and q2 are the charges on the two spheres, and r is the distance between their centers.

Given that the force of attraction is 0.108 N when the spheres are 50.0 cm apart, we can use the Coulomb's law to find the product of the charges on the spheres.

0.108 N = (9 * 10^9 N*m^2/C^2) * (q1 * q2) / (0.50 m)^2

The product of the charges on the two spheres is q1q2 = (0.108 N * (0.50 m)^2) / (9 * 10^9 Nm^2/C^2) = 1.2 * 10^-7 C^2

We can use this value to find the charges on the spheres when they are connected by a thin conducting wire and repelling each other with an electrostatic force of 0.0360 N.

0.0360 N = (9 * 10^9 N*m^2/C^2) * (q1 * q2) / (0.50 m)^2

q1q2 = (0.0360 N * (0.50 m)^2) / (9 * 10^9 Nm^2/C^2) = 4.0 * 10^-8 C^2

Since the product of the charges q1*q2 is now smaller, we can assume that one of the charges (let's say q1) is now smaller and the other charge (q2) is now bigger, hence have opposite charges.

We can use the formula q1q2 = 1.210^-7 C^2 / 4.0*10^-8 C^2 = 3q1q2

q2 = 3q1 and q1q2 = 4*10^-8 C^2

Substituting, we get q1 = (410^-8 C^2) / 3q1 = 1.3310^-8 C

The negative charge on one of the sphere is 1.33*10^-8 C

The net force is zero because it is moving at a constant speed. So, in the horizontal direction = 0. This will happen if the horizontal component of T, Tcos0 is equal to the frictional force.

It acts in a direction that is opposite to the motion or attempted motion of an object. Frictional force is caused by the microscopic irregularities on the surfaces that are in contact. The strength of the frictional force depends on the types of materials in contact and the amount of force pressing the two surfaces together.

An example of friction is when you try to slide a book across a table. The table exerts a frictional force on the book in the opposite direction of the motion, making it harder to slide the book. Another example is when you try to walk on a slippery surface, such as ice, the friction between your shoes and the ice is reduced, making it harder to walk.

Because of the inertia of the satellite's motion, it will proceed tangentially to its circular orbit at the same speed, or V.

The satellite will deviate from its course with its tangential velocity because there won't be any centripetal force to keep it in a circular orbit in the absence of gravitational force. Accelerations at the centripetal axis are produced by centripetal forces. Any satellite's circular motion around a celestial body, with the exception of the Earth's rotation around the Sun, is caused by the centripetal force generated by their mutual gravitational attraction.
