Amplitude is not measured from peak to trough, but from rest to peak or rest to trough.

The highest and lowest points on the surface of a wave are called crests and troughs respectively. The vertical distance between the peak and the trough is the height of the waves. The horizontal distance between two successive peaks or troughs is called the wavelength.

The amplitude of a wave is the maximum displacement of a particle on a medium with respect to its position of rest.

The amplitude can be thought of as the distance between rest and the peak. The amplitude from the rest position to the dip position can be measured in a similar manner.

Answer:

Density= 2.78 g/cm³

Relative density=2.8

Explanation:

To calculate the density of the cube we have to use the formula ρ=mass/volume

ρ stands for density.

So now we don't have the volume of the cube and to find the volume of the cube we have to use the formula a³

3³= 9 cm³

Now plug in the values. ρ= 25 g/9 cm³

ρ= 2.78 g/cm³

To find the relative density, we have to use the formula ρsample/ρH20

The sample means the density of the substance earlier. We do not know the density of water but it is constant at 997 kg/m³.

Now we have to make the units same so you change the unit of the density of cube to kg/m³

So, 25/1000= 0.025 kg

9/100×100×100 (because cm³ which means that there should be 3 meters to change the unit and to conver cm to meter we need to divide by 100 so 9cm/100, 9cm²/100×100, 9cm³/100×100×100)

=0.000009 m³

The new density= 0.025 kg/ 0.000009 m³

= 2777.78 kg/m³

Now plug the values into the formula:

relative density= 2.777.78 kg/m³ / 997 kg/m³

=2.8

There is no unit since kg/m³ and kg/m³ cancels

The molar concentration of sodium phosphate in the 200.0 mL solution is 0.03734 mol/L.

The molar concentration of sodium phosphate in a solution can be calculated using the formula:

Molar concentration (mol/L) = moles of solute / volume of solution (L)

First, we need to calculate the moles of sodium phosphate in the solution. We are given that 1.223 g of sodium phosphate (Na3PO4) is used to prepare a 200.0 mL solution.

To convert grams to moles, we need to divide the given mass by the molar mass of sodium phosphate, which is 163.9 g/mol.

Moles of sodium phosphate = 1.223 g / 163.9 g/mol = 0.007468 mol

Next, we need to convert the volume of the solution from milliliters (mL) to liters (L). Since 1 L is equal to 1000 mL, we divide the given volume by 1000.

Volume of solution = 200.0 mL / 1000 = 0.200 L

Now, we can calculate the molar concentration:

Molar concentration = 0.007468 mol / 0.200 L = 0.03734 mol/L

Therefore, the molar concentration of sodium phosphate in the 200.0 mL solution is 0.03734 mol/L.

Please note that the molar concentration is also referred to as molarity, and it represents the number of moles of solute per liter of solution. In this case, the molar concentration of sodium phosphate tells us the amount of sodium phosphate dissolved in the given solution.

Explanation:

At all points through her slide, it is important to reiterate that energy is always conserved.

Kinetic energy is the energy due to the motion of a body.

Potential energy is the energy due to the position of a body.

Based on the law of conservation of energy, energy is neither created nor destroyed but simply transformed from one form to another.

 So;

At all points:

           Total energy  = Potential energy + Kinetic energy

Since the initial energy  = 5000J which is the potential energy

This is the total energy within the system as the kinetic energy at this point is 0;

 After a few seconds, the potential energy is 1928J;

The back side of a polished spoon has f = -6.50 cm (convex). If you

hold your nose 5.00 cm from it then the  magnification of the image is

0.864.

The formula for calculating magnification in such a case is: Magnification = -di/do

Here, f = -6.50 cm is the focal length of the mirror, and the object is the back side of a polished spoon.

The distance between the object and the mirror, in this case, is the distance between your nose and the spoon, which is 5.00 cm.

Thus, the distance of the image from the mirror is:di = -f/(1/do - 1/f)

Putting the values in the formula, we get:di = -6.50/(1/5 - 1/-6.50) = -4.32 cm (negative sign indicates that the image is virtual)

Using the magnification formula, we have: Magnification = -di/do = -(-4.32)/5.00 = 0.864

Thus, the magnification of the image is 0.864.

The change will double the electric field between the plates is (a) Bring the plates so that they are 0.01 m apart.

The electric field between the plates of a parallel plate capacitor is given by E = V/d, where V is the voltage between the plates and d is the distance between them.

a) If the plates are brought closer together to a distance of 0.01 m, the electric field between them will double. The new electric field will be E = (1000 V)/(0.01 m) = 100,000 V/m.

b) This statement is incorrect. Changing the distance between the plates or the area of the plates will affect the electric field, but not necessarily double it.

c) Increasing the voltage across the plates to 1500 V will not double the electric field. The new electric field will be E = (1500 V)/(0.02 m) = 75,000 V/m.

d) Increasing the area of the plates will not double the electric field. The new electric field will be E = (1000 V)/(0.02 m) = 50,000 V/m, which is half the original electric field.

e) Increasing the distance between the plates to 0.04 m will not double the electric field. The new electric field will be E = (1000 V)/(0.04 m) = 25,000 V/m, which is one-fourth the original electric field.

Therefore, the correct answer is (a) Bring the plates so that they are 0.01 m apart.

Structures are determined by two principal factors: the relative sizes of the ions and the ratio of the numbers of positive and negative ions in the compound.

Ionic compounds at a molecular level are arranged in definite patterns to give a crystalline structure leading to a high melting point, high boiling point and high density in ionic compounds.

In ionic bond is formed when a metal transfers electrons to a nonmetal and an ion pair is formed. The ions are held together by strong electrostatic interaction as described by Coulomb's law.

However, the smallest unit of an ionic substance is called the formula unit. The compound arranges itself in definite patterns to form a crystalline lattice. Hence, the structure of ionic compound is highly ordered. This leads to a high melting point, high boiling point and high density in ionic compounds.

A change in wind direction will not have a significant effect on maintaining a 3° glide slope at a constant true airspeed, but it may require some minor adjustments in heading or pitch to compensate for any deviations caused by the wind.

A change in wind direction will have an effect on maintaining a 3° glide slope at a constant true airspeed. The glide slope is determined by the vertical and horizontal components of the aircraft's velocity. If there is a crosswind, it will cause the aircraft to drift off course, which could lead to a deviation from the desired glide slope. The pilot will have to adjust the aircraft's heading to compensate for the crosswind and maintain the desired glide slope.

The ball goes 8.62m high.

In physics, gravitational acceleration refers to the speed at which a body falls freely in a vacuum (and thus without experiencing drag). This is the constant acceleration brought on just by the gravitational pull. Gravimetry is the measurement and study of these rates. All bodies accelerate at the same rate in vacuum, independent of their masses or compositions.

u(initial velocity of the ball) = 13 m/s

m(mass of the ball ) = 0.25kg

total energy = Kinetic energy + Potential energy

Initially,

Kinetic energy =  0.5 x 0.25 x 13 x 13 J = 21.125J

Potential energy = 0 J

Finally,

Kinetic energy =  0 J

Potential energy = mass x gravitational acceleration x height

Since total energy is conserved ,

Initial kinetic energy = final potential energy

21.125J = 0.25 x 9.8 x height

Thus , height = 8.622

Explanation:

it goes from low-temperature to high-temperature because it's reacting

Answer:

Explanation: Thermal energy is transferred through water by conduction, convection, and radiation. Conduction occurs when heat is transferred through direct contact between water molecules with different thermal energy. Convection occurs when warmer water rises to the top and cooler water sinks to the bottom, creating a circular motion that distributes heat. Radiation is the transfer of energy through electromagnetic waves, but it is not significant in water due to poor conduction. The specific mechanism that dominates heat transfer depends on various factors such as temperature gradient, depth, and presence of other materials.
