Hazel recently read an article that claimed that radio waves can cause electron displacement. Based on

Physics
1 answer:
iren [92.7K]2 years ago
3 0

Answer:

Based on  the passage, the article's claim is not true.  Therefore, the answer is:

No, because radio waves  have energies that are too  low to fall in the ionizing  range.

Explanation:

Radio waves are generally known as forms of non-ionizing radiation.  This means that they do not have enough energy, unlike microwaves, to separate electrons from atoms or molecules, thereby ionizing them.  They cannot cause electron displacement, as claimed in the article.  Therefore, they cannot break chemical bonds, which can cause chemical reactions or DNA damage. As non-ionizing radiation, radio waves occur at lower frequencies in the electromagnetic spectrum.

Calculate Gravitational Potential Energy for an object on Earth with a mass of 2 kg and a height of 7 m.
victus00 [196]

Answer:

137.2J

Explanation:

Ep= mgh

Given,

  • m=2kg
  • h=7m

and we know, g = 9.81 N/kg

Ep= 2 × 9.81 × 7

Ep= 137.2J

2. A truck speeds up from a velocity of 6 m/s to 14 m/s in 4 seconds. What is the trucks acceleration? SHOW YOUR WORK
zavuch27 [327]

#2

As it is given here

initial speed is

v_i = 6 m/s

After 4 seconds the final speed is

v_f = 14 m/s

so here we can use the formula of acceleration using kinematics

a = \frac{v_f - v_i}{t}

a = \frac{14 - 6}{4}

a = 2 m/s^2

so here it will accelerate at 2 m/s^2 rate.

#3

As it is given here

initial it starts from rest

v_i = 0 m/s

After 2.5 seconds the final speed is

v_f = 15 m/s

so here we can use the formula of acceleration using kinematics

a = \frac{v_f - v_i}{t}

a = \frac{15 - 0}{2.5}

a = 6 m/s^2

so here it will accelerate at 6 m/s^2 rate.


#4

i think question is not correct as in first line it is saying about a bag of trash and then in next line it is asking for the position of Jumper and bridge.
