The distance between two wavefronts is termed as wavelength.

The wavelength of a sound wave is defined as the space between two adjacent wavefronts. The number of wavefronts the observer detects during a period of time can be used to calculate the wave's frequency.

The medium (such as a vacuum, air, or body of water) through which a wave travels determines its wavelength. Waves can be anything from music to light to water to periodic electrical signals. While light and other electromagnetic radiation use variations in electric and magnetic field strength, sound waves are variations in air pressure. Water waves are fluctuations in a body of water's height. Atomic locations change during the shaking of a crystal lattice.

The specific heat capacity of the metal, cm is 214.87 J/kg-k.

As per the given data,

we need to find  the specific heat capacity of the metal, cm.

According to the above question,

it is given that,

Weight of  chunk of an unknown metal is 1.00kg

chunk has been in boiling water for several minutes and it is quickly dropped into an insulating Styrofoam beaker containing 1.00kg of water at 18.0°C.

After stirring for 5.00 minutes, the water's temperature has reached a constant value of 22.0°C .

The water specific heat capacity  is cw = 4190J/(kg)  

Now,

temperature of metal is 100 degree celsius ( water boils at 100 degree celsius )

equilibrium temperature = 22 degree celsius

specific heat capacity of water Cw= 4190 J/kg-K

According to question, specific heat capacity of metal be Cm

Therefore,

mass of metal that is Mm = 1 kg

mass of water that is Mw = 1 kg

we know that,

heat energy lost by metal is equal to  heat energy gained by water

(assuming no heat is lost to the surroundings)

heat energy lost by metal = Mm * Cm * (100 - 22)

heat energy lost by water = Mw * Cw * (22 - 18 ) (given - initial temperature of water = 18 degree celsius)

therefore,

Mw * Cw * (22 - 18 ) = Mm * Cm * (100 - 22)

4190 * 4 = Cm * 78

Cm = 214.87 J/kg-k

Hence, the specific heat capacity of the metal, cm is 214.87 J/kg-k.

To solve a line cut by a transversal, use the properties of parallel lines, such as corresponding angles and alternate interior angles, to find the unknown angle measurements.

When a line is cut by a transversal, a number of simultaneous equations can be formed by using the properties of parallel lines. For example, the corresponding angles of the lines will always be equal, the alternate interior angles will be equal, and the consecutive interior angles will add up to 180 degrees. Using these properties, you can identify the unknown angle measurements. For example, if the measure of one of the corresponding angles is known, the measure of the other corresponding angle can be determined simply by using the fact that they are equal. Similarly, if one of the alternate interior angles is known, the other can be determined using the fact that they are equal.

The loss of kinetic energy of the moving car is 238,866 J

Kinetic energy is the energy in a moving object due to its motion,

K.E. = 1/2 M[tex]V^{2}[/tex]

Given in the question,

Mass of big car M1 = 1640 kg

Mass of small car M2 = 820 kg

Initial velocity of big car V1 = 0

Initial velocity of small car V2 = 25.6 km/s

using the principle of conservation of momentum,

Total momentum before collision = total momentum after collision

M1V1 + M2V2 = V (M1+M2)

1640 × 0 + 820×25.6 = V ( 1640+ 820)

V = 820 ×25.6 /2460

The net force acting on the bicyclist along with its own weight is 687 N. The magnitude of acceleration for this force is 10.56 m/s².

Force is a physical quantity characterised by its magnitude and direction. Force deform an object or changes its state of rest or motion. Force of a moving body  is the product its mass and acceleration.

The normal force acting on an object by ts weight = mg

thus normal force on 65 kg bicyclist = 65 Kg × 9.8 m/s² = 637 N.

The dragging force acting on him = 50 N.

The resultant force = 637 N + 50 N = 687 N

Force = m a

acceleration  = force/ mass

Answer:

the correct answer is B) 27.

Explanation:

To find the angle of refraction, you can use the formula:

n1 * sin(angle of incidence) = n2 * sin(angle of refraction)

where n1 and n2 are the refractive indices of the two media (in this case, air and the liquid), and the angles are measured from the normal to the surface.

Plugging in the values from the problem, we have:

1 * sin(40) = 1.5 * sin(angle of refraction)

Solving for the angle of refraction, we get:

angle of refraction = sin^-1(1/1.5 * sin(40))

Using a calculator or a table of trigonometric functions, we can find that the value of sin^-1(1/1.5 * sin(40)) is approximately 27.3 degrees.

Therefore, the correct answer is B) 27.
