Yes, if a body is floating in a liquid, the rise in the liquid level is equal to the body height. This phenomenon is known as Archimedes' principle.

Archimedes' principle says when a body is immersed in a fluid (liquid or gas), it experiences an upward buoyant force equal to the weight of the fluid displaced by the body. Buoyant forces act in the opposite direction to gravity.

When a body floats in a liquid, it displaces a volume of liquid equal to its volume. As a result, the liquid level rises by an amount equal to the height of the submerged part of the body.

This principle holds for objects that float or are partially immersed in a liquid, such as a buoyant boat or a floating object. However, if the body sinks completely into the liquid, the liquid level rise will no longer be equal to its height. Instead, it depends on the density and volume of the submerged object.

that the relative placements of the charges as well as their multiples affect a set of ions' potential energy. When the specific charge have the same sign or have equal signs, the energy is positive. Or else, it is negative.

The force acting just on two objects affects the potential energy formula. The formula for gravitational force is P.E. (= mgh, where g seems to be the acceleration caused by gravity (9.8 m/s2 at the earth's surface) while h represents the elevation in metres.

As a result, the system's potential energy equals the sum of a work that was done to set up the entire system of two counts. The potential energy that exists in the combination of two charges in such an external field can be stated as follows: q1V(r1) = q2V(r2) + (q1q2/4or12).

The expression \(X^{N} + Y^{N}\)is not divisible by X - Y (where Y is not equal to 0).

To determine whether the expression \(X^{N} + Y^{N}\) is divisible by X - Y (where Y is not equal to 0), we can use the factor theorem and the property of binomial expansion.

The factor theorem states that if a polynomial P(x) is divisible by (x - a), then P(a) equals zero. In our case, if \(X^{N} + Y^{N}\) is divisible by (X - Y), then when we substitute X = Y into the expression, the result should be zero.

Let's substitute X = Y into the expression:

\(Y^{N} + Y^{N}\)

Since \(Y^{N}\) is equivalent to \(Y^{N}\) , the expression becomes:

2(\(Y^{N}\))

We can see that the expression 2(\(Y^{N}\)) is not equal to zero unless Y is equal to zero. Therefore, if Y is not equal to zero, \(X^{N} + Y^{N}\) is not divisible by X - Y.

In summary, unless Y is equal to zero, the expression \(X^{N} + Y^{N}\) is not divisible by X - Y according to the factor theorem and the given condition.

Explanation:

Answer:

Approximately \(1000 \; {\rm N}\) (assuming that \(g = 10\; {\rm N \cdot kg^{-1}}\).)

Explanation:

The buoyant force on an object is equal to the weight of the liquid that this object has displaced.

In this example, the object displaced \(V = 0.1\; {\rm m^{3}}\) of water. The density of water is \(\rho = 1.00 \times 10^{3}\; {\rm kg \cdot m^{-3}}\). Thus, the mass of the water displaced would be \(m = \rho\, V = 1.00 \times 10^{2}\; {\rm kg}\).

Since \(g = 10\; {\rm N \cdot kg^{-1}}\) by assumption, the weight of that \(m = 1.00 \times 10^{2}\; {\rm kg}\) of water would be \(m\, g = 1.00 \times 10^{3}\; {\rm N}\). Hence, the buoyant force on this object would be \(1.00 \times 10^{3}\; {\rm N}\), which is \(1000\; {\rm N}\) when rounded to one significant figure (as in volume.)

The change in motion, visible effects of the collision, and temperature increase would all serve as evidence that energy was transferred during the collision between the cart and the track after the removal of electrostatic forces.

If the electrostatic forces on the cart and track were suddenly removed and the cart hits the track, there would be several pieces of evidence indicating that energy was transferred during the collision.Firstly, there would be a noticeable change in the motion of the cart. The cart would decelerate as it collides with the track, and its velocity would decrease due to the loss of energy. This change in motion demonstrates that energy has been transferred from the cart to the track.

Secondly, there may be visible effects of the collision, such as deformation or damage to the cart or the track. This deformation or damage occurs because the energy transferred during the collision is transformed into other forms, such as heat or sound energy. These visible effects provide evidence of energy transfer.Additionally, there could be an increase in the temperature of the cart and/or the track due to the conversion of kinetic energy into thermal energy upon impact. This temperature change would be another indication that energy has been transferred.

The net force on particle q₂, located between particles q₁ and q₃, is approximately 189000 N. The force exerted by particle q₁ on q₂ is positive and equals 252000 N, while the force exerted by particle q₃ on q₂ is negative and equals -63000 N.

To find the net force on particle q₂, we need to calculate the individual forces exerted on q₂ by particles q₁ and q₃ and then determine their sum.

The force between two charged particles can be calculated using Coulomb's law:

F = k * |q₁ * q₂| / r²

Where F is the force between the particles, k is the electrostatic constant (k ≈ 9.0 x \(10^9\) Nm²/C²), q₁ and q₂ are the charges of the particles, and r is the distance between them.

First, let's calculate the force exerted on q₂ by q₁:

F₁₂ = k * |q₁ * q₂| / r₁₂²

F₁₂ = (9.0 x \(10^9\) Nm²/C²) * |(8.0 μC) * (3.5 μC)| / (0.10 m)²

F₁₂ ≈ 252000 N

The force is positive because q₁ and q₂ have opposite charges.

Next, let's calculate the force exerted on q₂ by q₃:

F₂₃ = k * |q₂ * q₃| / r₂₃²

F₂₃ = (9.0 x \(10^9\)Nm²/C²) * |(3.5 μC) * (-2.5 μC)| / (0.15 m)²

F₂₃ ≈ -63000 N

The force is negative because q₂ and q₃ have the same charge.

Finally, we can find the net force on q₂ by summing the individual forces:

Net force = F₁₂ + F₂₃

Net force = 252000 N + (-63000 N)

Net force ≈ 189000 N

The net force on particle q₂ is approximately 189000 N.

(a) The distance  the car travels during your reaction time is 2.83 m.

(b) The total distance traveled by the car before stopping is 97.8 m

To find the distance traveled during the reaction time, we need to find the velocity after the reaction time and then use it to find the distance traveled.

78 km/h = 78,000 m/h ÷ 3600 s/h = 21.67 m/s

After the reaction time, the velocity is equal to the initial velocity plus the acceleration during the reaction time:

v = v₀ + at

v = 21.67 m/s - (4.6 m/s²)(0.130 s)

v = 21.67 m/s - 0.599 m/s

Finally, the distance traveled during the reaction time is given by:

d = v₀t  + ¹/₂at²

d  = 21.67  x 0.130 s    +    ¹/₂(-4.6) x (0.130)²

d = 2.83 m

B) To find the total distance traveled before stopping, we need to find the time it takes for the velocity to reach 0.

The velocity after the reaction time is equal to 21.67 m/s - 0.599 m/s = 21.07 m/s.

Using the equation v = v₀ + at, we can find the time it takes to come to a stop:

t = -v₀ / a

t = -21.07 / -4.6

t = 4.58 s

The total distance traveled can be found using the equation:

d =  v₀t  + ¹/₂at²

d  = 21.67 x 4.58  + ¹/₂(-4.6) x 4.58

A ray diagram with given information gives an image location of 10.7 cm on the ruler. This method helps determine characteristics of images formed by lenses.

To build a beam graph to decide the picture area, we first need to draw an outline with the given data. We start by defining an upward boundary to address the focal point, with the ruler and the dark spot on one or the other side of it. We then, at that point, draw a bolt on the left half of the focal point at the 3.0 cm mark.

Then, we draw three beams from the bolt. The primary beam is attracted lined up with the important pivot and goes through the point of convergence on the right half of the focal point.

The subsequent beam goes through the focal point of the focal point and go on in an orderly fashion. The third beam goes through the point of convergence on the left half of the focal point and becomes lined up with the essential pivot subsequent to going from the perspective.

Where these three beams cross on the right half of the focal point is the picture area. For this situation, the beams converge at a point situated at 10.7 cm on the ruler, which is the response to the inquiry. Thusly, the picture is situated at 10.7 cm on the ruler.

This strategy for developing a beam graph is a valuable apparatus in deciding the area and qualities of pictures shaped by focal points, and is a significant idea in the investigation of optics.

The average acceleration of the motorcycle over the given distance is approximately 9.39 m/s².

To calculate the average acceleration of the motorcycle, we can use the formula:

Average acceleration = (final velocity - initial velocity) / time

First, let's convert the final velocity from km/h to m/s since the distance is given in meters. We know that 1 km/h is equal to 0.2778 m/s.

Converting the final velocity:

Final velocity = 78 km/h * 0.2778 m/s = 21.67 m/s

Since the motorcycle starts from rest (initial velocity is zero), the formula becomes:

Average acceleration = (21.67 m/s - 0 m/s) / time

To find the time taken to reach this velocity, we need to use the formula for average speed:

Average speed = total distance/time

Rearranging the formula:

time = total distance / average speed

Plugging in the values:

time = 50 m / 21.67 m/s ≈ 2.31 seconds

Now we can calculate the average acceleration:

Average acceleration = (21.67 m/s - 0 m/s) / 2.31 s ≈ 9.39 m/s²
