Someone places a chocolate bar near a working radar set that is used to locate ships and airplanes. which best describes what is

likely to happen to the chocolate bar? it changes color as it absorbs visible light from the radar set. it softens and melts as it absorbs microwaves from the radar set. it becomes radioactive after it absorbs gamma rays from the radar set. it begins to fluoresce after it absorbs ultraviolet light from the radar set.

The chocolate softens and melts as it absorbs the microwaves, and it makes a mess.

Answer: Option (b) is the correct answer.

Explanation:

A radar emits microwaves which have longer wavelengths and a frequency range of 1 GHz to 300 GHz.

The microwaves are like electromagnetic waves and produces heat due to the emission of radiation.

Thus, when a chocolate bar is placed near a working radar set that is used to locate ships and airplanes then the chocolate bar will softens and melts as it absorbs microwaves from the radar set.

Aleksandr-060686 [28]

Answer:

The time is  t = 0.02 \ s  

Explanation:

From the question we are told that

  The period of the circuit is  T  =  0.04

Generally voltage maximization of the capacitor occurs during the voltage minimization of the inductor and vise versa

So the time between the voltage maximization of the capacitor and that of the inductor is mathematically represented as

           t = \frac{T}{2}

=>        t = \frac{0.04}{2}

=>        t = 0.02 \ s

A proton travels with a speed of 5.02×10⁶ m/s in a direction that makes an angle of 60.0° with the direction of a magnetic ficld
lesantik [10]
Answer: The magnitude of the proton's acceleration is 0.748 ×10^14 m/s²

Explanation:
the velocity ,v, of ththe proton = 5.02×10^6 m/s
Magnitude , B , of the magnetic field = 0.180 T

First , we need to find the magnitude of the Force on the proton. This is given by the relation :
F = q(v x B) = qvBsinθ

where 'q' is the charge of proton , q= 1.6×10^-19 C
θ is the angle the proton makes with the direction of the magnetic field

Putting the respective values of v, B ,θ in the above equation, we get:

F = (1.6×10^-19 C)(5.02×10^6 m/s)(0.180T) sin60°
∴ F = 1.25 ×10^-13 N

Now , from Newton's second law we know that ,
F=m×a

∴ a = F/m

Mass of a proton = 1.67×10^27 kg
a= 1.25 × 10^-13 N / 1.67 × 10^27 kg

a= 0.748 × 10^14 m/s² =acceleration of the proton
