inverted, real, behind the lens is the answer

Answer:

Inverted

Real

Behind the lens

Explanation:

As we know that

$d_o = 16 cm$

$d_i = 16 cm$

also we know that

$h_o = 4 cm$

$h_i = -4 cm$

now we know that magnification is given by

$M = \frac{d_i}{d_o} = \frac{h_i}{h_o}$

so we can say here that

M = 1

so here image size will be same as object size and it must be real and inverted as magnification is negative in sign

Define potentiol energy , kenetic energy.

Pani-rosa [81]

Potential energy is stored energy. For example, if a bowling ball is on top of a giant hill, we say it has potential energy because it has the potential to do work which is to roll down the hill.

Kinetic energy is the energy of movement so once that ball rolls down that hill, that potential energy is converted to kinetic energy.

Telephone signals are often transmitted over long distances by microwaves. What is the frequency of microwave radiation with a w

amm1812

Answer:

1) f= 8.6 GHz

2) t= 0.2 ms

Explanation:

Since microwaves are electromagnetic waves, they move at the same speed as the light in vacuum, i.e. 3*10⁸ m/s.
There exists a fixed relationship between the frequency (f) , the wavelength (λ) and the propagation speed in any wave, as follows:

$v = \lambda * f (1)$

Replacing by the givens, and solving for f, we get:

$f =\frac{c}{\lambda} =\frac{3e8m/s}{0.035m} = 8.57e9 Hz (2)$

⇒ f = 8.6 Ghz (with two significative figures)

Assuming that the microwaves travel at a constant speed in a straight line (behaving like rays) , we can apply the definition of average velocity, as follows:

$v =\frac{d}{t} (3)$
