What disadvantage of convex mirror​

Physics
1 answer:
Eddi Din [679]3 years ago
5 0

Answer:

The disadvantage is that convex mirror is that they make it appear like those objects are at a more noteworthy distance than they actually are. It always gives a virtual, erect and a diminished image.

True or false: the most appropriate weights to use in the wacc are book value weights.
Veseljchak [2.6K]

This statement is false as the most appropriate weights to use in the wacc are market value weights.  

The weighted average cost of capital (WACC) is the amount that a company anticipates charging on average to all of the holders of its securities in order to fund its assets (WACC).

Each capital source's cost (debt and equity) is multiplied by the appropriate weight by market value when computing WACC, and the results are then added up to arrive at the final calculation.

It matters that the external market, not management, is in charge.

The WACC is the rate of return a company must get on its base of existing assets to appease its owners, creditors, and other financiers; otherwise, they will hunt for alternative investments.

The formula Sequals16tsquared is used to approximate the distance​ S, in​ feet, that an object falls freely from rest in t secon
Tom [10]

S = 16t² where t = time in seconds.

Let S = 1190ft then solve for t:

16t² = 1190

t² = 74.4

t = 8.62s

What quantity is represented by a unit called newton (N) ?
bixtya [17]

Newton is the SI unit of force . Newton is the name of a British scientist and the name of unit is to honour him. The unit is actually Kg.m/s 2 The unit can be derived by the formula. Take the example of weight. It's formula is W = mg . We know that the unit of mass is kg and gravity is m/s 2 so the unit of weight becomes kg.m/s 2 This unit is known as a Newton. It is always given a capital letter because it is someone's name. Other units that are always capitalised (upper case) are Ampere (Amp), Watt, Volt, Coulomb, Kelvin, Celsius, Fahrenheit, Curie, Roentgen because they are also people's names.

Write a hypothesis about the effect of the wavelength on the diffraction angle. Use the "if . . . then . . . because . . ." form
adell [148]
A) Wavelength is the distance between two successful crests or troughs in a transverse wave or the distance between two successful compressions or rarefactions in a longitudinal wave. if the wavelength of a wave is long then the wave will diffracts more compared to a wave with a shorter wavelength because the size of the wavelength is proportional to the angle of diffraction. Such that if the gap is larger than the wavelength then the wave passes through the gap and does not spread much on the other side, while when the gap size is equal to the wavelength, maximum diffraction occurs and the waves spread greatly out.

b) Diffraction is a phenomenon that occurs when a wave encounters an obstacles or a slit. It is referred to as the bending of light around corners of an obstacles or aperture into the region of geometrical shadow of the obstacle. It is caused by one wave of light is shifted by the diffracting object which will in turn cause the wave to have interference with itself. (either constructive or destructive)

¿Diferencias entre movimiento vertical y horizontal?​
Ronch [10]

Answer:

Los movimientos verticales o circulación convectiva consisten en un intercambio de lugar entre el aire caliente de las capas bajas y el aire frío de las superiores. Este movimiento se debe a la diferencia de densidades de las distintas masas de aire. Los movimientos horizontales se basan en las diferencias de presión.
