A solute will dissolve more quickly if the solvent particles are moving faster and therefore collide with the surface of the solid solute pieces more often.

Which condition will cause this to occur?

We are given that a skater starts at a height of 2 meters. If we do a balance of energy and assume that there is no friction or any other nonconservative forces we get:

Where:

We can cancel out the mass and the acceleration of gravity:

Substituting the initial height we get:

Therefore, on the other side, he will get to 2 meters in height.

Pressure will decrease whenever the surface area increases, and when the weight of the object is reduced.

We know that,

\(\large \boxed{ \mathrm{pressure = \frac{mass}{area \: \: of \: \: surface}} }\)

Now, we can observe that the area of surface is inversely proportional to the pressure, Therefore pressure will change opposite to the change in surface area in contact.

So, if we increase the surface area then there would be decrease in magnitude of pressure.

Total, 110 ohms resistance you would need to the circuit in order to limit the current to 2 amperes.

To limit the current in the circuit to 2 amperes, we can use Ohm's Law, which states that the current (I) in a circuit is equal to the voltage (V) divided by the resistance (R);

I = V / R

Given;

Operating voltage (V) = 220 volts

Circuit resistance (R) = 55 ohms

Desired current (I_desired) = 2 amperes

We wil rearrange Ohm's Law to solve for the resistance required to achieve the desired current;

R_required = V / I_desired

Substituting the given values, we have;

R_required = 220 V / 2 A

Calculating the division, we find;

R_required = 110 ohms

Therefore, you would need to add an additional resistance of 110 ohms to the circuit in order to limit the current to 2 amperes.

Answer:  46.0455 cm

Explanation:

The kinetic energy of the puck is 2.75625 Joules.

This energy is used to compress the spring and bring the puck to rest. The work done on the puck by the spring is equal to the change in kinetic energy of the puck, which is the kinetic energy it initially had.

The work done on the puck by the spring can also be expressed as the potential energy stored in the spring at the point of maximum compression, which is given by the formula \(\( \frac{1}{2} k x^2 \)\), where \(\( k \)\) is the spring constant and \(\( x \)\) is the distance the spring is compressed.

Setting these two expressions for the work done equal to each other gives:

\(\( \frac{1}{2} k x^2 = 2.75625 J \)\)

We can solve this equation for \( x \), the distance the spring is compressed.

The spring will compress approximately 0.460455 meters, or 46.0455 cm, before the puck is brought to rest.

Assuming that the man is standing still on a flat, horizontal surface and neglecting air resistance, the normal force produced by the ground upwards on the leg would be equal in magnitude to the weight of the man, which is given as approximately 84 kg.

Therefore, the normal force being produced by the ground upwards on the leg would be approximately 84 kg multiplied by the acceleration due to gravity (9.81 m/s^2), which gives a value of approximately 823.44 N (Newtons).

So the normal force being produced by the ground upwards on the leg is approximately 823.44 N.

Answer:

Mercury has the shortest orbit

Explanation:

Its right

Answer:

200 m / min

Explanation:

Total distance = 2000 m

Total time = 2+4+1+3 = 10 minutes

Average speed = 2000 m / 10 min = 200 m/min

Plugging in the given values and solving for the final velocity of the 6kg block will give you the speed of the 6.00-kg block after it has descended 1.50 m. In this case, the normal force is the weight of the 8kg block, and the displacement is the distance that the 8kg block moves.

To calculate the speed of the 6.00-kg block after it has descended 1.50 m, you can use the conservation of mechanical energy. The initial mechanical energy of the system is the potential energy of the 6.00-kg block (mgh) and the potential energy of the 8.00-kg block (mgh). As the blocks move, some of this energy is converted into kinetic energy, and some is lost to friction. The equation for the conservation of mechanical energy is:

E_initial = E_final + W_friction

Where E_initial is the initial mechanical energy of the system, E_final is the final mechanical energy of the system, and W_friction is the work done by friction.

The final mechanical energy of the system is the kinetic energy of the 6.00-kg block (1/2 mv²) and the potential energy of the 8.00-kg block (mgh).

To calculate the work done by friction, you can use the equation:

W_friction = force x distance x cos(theta)

Where force is the force of friction, distance is the distance over which the force of friction acts, and theta is the angle between the force of friction and the displacement. The force of friction is the coefficient of kinetic friction times the normal force.

In this case, the normal force is the weight of the 8kg block, and the displacement is the distance that the 8kg block moves.

W_friction = m_kF_nd

Where m_k = 0.25 is the coefficient of kinetic friction, F_n = 8*9.8 N is the normal force, and d = 1.5m is the distance that the 8kg block moves.

Plugging in the given values and solving for the final velocity of the 6kg block will give you the speed of the 6.00-kg block after it has descended 1.50 m.

The car must start at a height of approximately 127.55 meters on the hill in order to achieve a speed of 50 m/s at the bottom, assuming it is engineless and resistance-free.

To determine the height on a hill at which an engineless, resistance-free car must start in order to achieve a speed of 50 m/s at the bottom, we can use the principle of conservation of mechanical energy.

According to this principle, the sum of the potential energy and the kinetic energy of an object remains constant in the absence of external forces.

At the top of the hill:

The car has only potential energy (PE) due to its height above the bottom.

At the bottom of the hill:

The car has both potential energy and kinetic energy (KE).

Since the car is engineless and resistance-free, we can neglect any energy losses due to friction or air resistance.

The total mechanical energy (E) at the top of the hill is equal to the total mechanical energy at the bottom of the hill:

Etop = Ebottom

The potential energy (PE) at the top of the hill is given by the formula:

PE = m * g * h

Where m is the mass of the car, g is the acceleration due to gravity, and h is the height of the hill.

The kinetic energy (KE) at the bottom of the hill is given by the formula: KE = (1/2) * m * \(v^{2}\),

Where v is the speed of the car at the bottom.

Therefore, we have:

PEtop = KEbottom

m * g * h = (1/2) * m * \(v^{2}\)

We can cancel out the mass (m) from both sides of the equation:

g * h = (1/2) * \(v^{2}\)

Now, we can solve for the height (h):

h = (1/2) * \(v^{2}\) / g

Substituting the given values:

v = 50 m/s (speed at the bottom)

g = 9.8 m/\(s^{2}\) (acceleration due to gravity)

h = (1/2) * \((50 m/s)^2\) / (9.8 m/\(s^{2}\))

h = 127.55 m

Therefore, the car must start at a height of approximately 127.55 meters on the hill in order to achieve a speed of 50 m/s at the bottom, assuming it is engineless and resistance-free.

To determine the number of half-lives that have elapsed, we need to compare the ratio of 14C to 14N atoms found in the hip bone fragment.

The ratio of 1 14C atom for every 31 14N atoms suggests that the hip bone fragment contains a smaller amount of 14C compared to the expected ratio found in a living organism. Since 14C undergoes radioactive decay with a half-life of approximately 5730 years, we can calculate the number of half-lives that have elapsed by observing how many times the ratio needs to double to reach the expected ratio.

In this case, if the expected ratio is 1:1, then the observed ratio of 1:31 would require five doublings to reach 1:1. Therefore, approximately five half-lives have elapsed since the death of the organism from which the hip bone fragment originated.

Answer:

Explanation:

Aaron yogurt supremacy

the force between the two wires if they are separated by 2.50 cm is 0.525 N.

Given that force F between two parallel wires carrying electric currents is inversely proportional to the distance d between the wires and that a force of 0.750 N exists between wires that are 1.75 cm apart and that we are supposed to find the force between them if they are separated by 2.50 cm.

Let the initial force be F₁ and the initial distance be d₁.

Therefore, we can write the relationship between force and distance as;

F₁d₁ = F₂d₂

Where

;F₁ = 0.750 N (initial force)

d₁ = 1.75 cm (initial distance)

F₂ = ? (force at new distance)

d₂ = 2.50 cm (new distance)

Let us find F₂;F₁d₁ = F₂d₂F₂ = F₁d₁/d₂

Now substitute the values we know;

F₂ = (0.750 N x 1.75 cm) / 2.50 cmF₂ = 0.525 N

Therefore, the force between the two wires if they are separated by 2.50 cm is 0.525 N.

Hence, the correct option is (c).

The solar constant (S) does not get larger as you get further from the Sun. It actually gets smaller due to the decrease in solar radiation received per unit area with increasing distance from the Sun.

False. The further you get from the Sun, the solar constant (S) actually gets smaller, not larger.

The solar constant is a measure of the amount of solar radiation received per unit area at a distance of one astronomical unit (AU) from the Sun. It represents the average power per unit area received from the Sun at Earth's orbit. Since the solar constant is defined at a fixed distance from the Sun, it does not change as one moves away from it.

According to the inverse square law, the intensity of radiation decreases with increasing distance from the source. This means that as you move further from the Sun, the same amount of solar energy is spread over a larger area, resulting in a decrease in the solar radiation received per unit area.

Therefore, the solar constant is highest at a distance of one AU from the Sun, which is approximately the average distance between the Earth and the Sun. As you move closer to the Sun, the intensity of solar radiation increases, but as you move farther away, it decreases.

In a collision between two objects, both objects experience forces that are equal in magnitude and opposite in direction.

Collision between two objects naturally fall under Newton's third law of motion. When two objects collide, forces of equal magnitude and opposite direction are applied to each object. Such pressures frequently result in one thing gaining momentum and gaining speed while the other object slows down (lose momentum).

Newton's third law states that the forces acting on the two objects are of equal and opposite strength. The objects' accelerations may not be equal in magnitude even though the forces acting on them are opposite in direction and of equal magnitude. According to Newton's second law of motion, an object's acceleration depends on both its mass and force.
