Answer:

Here you go!

Explanation:

Gamma rays have the highest energy radiation and have the smallest wavelength in the electromagnetic spectrum.  They are formed by the hottest and most energetic objects in the world, with nuclear explosions, lightning and far less radioactive decay activity producing gamma rays. It can be both useful and dangerous, gamma rays are used in medicine to treat cancer with radiation when exposed to them, radiology, sterilization and much more.

Answer:

Gamma Rays

Explanation:

Gamma rays have the highest energy radiation and have the smallest wavelength in the electromagnetic spectrum. Gamma rays are ionizing electromagnetic radiation, obtained by the decay of an atomic nucleus. Gamma rays are more penetrating, in matter, and can damage living cells to a great extent. Gamma rays are used in medicine (radiotherapy), industry (sterilization and disinfection) and the nuclear industry.

The extremely high energy of gamma rays allows them to penetrate just about anything. They can even pass through bones and teeth. This makes gamma rays very dangerous. They can destroy living cells, produce gene mutations, and cause cancer.

A rectangle has an area measuring 1350 square centimeters. Its length and width are whole numbers of centimeters. What are the p
Aleks04 [339]

The smallest perimeter of the rectangle is of value 150 cm.

Given:

The area of the rectangle, A = 1350 cm²

Calculation:

Let the length of the rectangle be 'x'

      the breadth of the rectangle be 'y'

We know that the area of a rectangle is given as:

A = (x) × (y)  

Applying values in the above equation we get:

xy = 1350 cm²

Factorizing the value of 1350, the possible values of length and breadth of the rectangle is as listed below:

x (cm)         y (cm)

1350      ×       1

675       ×       2

450       ×       3

270       ×       5

225       ×       6

150        ×       9

135        ×       10

90         ×       15

75         ×        18

54         ×        25

50         ×        27

45         ×        30         (least possible value)

Thus, the smallest perimeter of the rectangle can be calculated as:

P = 2 (x + y)

  = 2 (45 + 30)

  = 150 cm

Therefore, the smallest perimeter that the rectangle will have is 150 cm.

If you hit another object with your vehicle, your _____ will be slowed or stopped by the force of impact caused by that object u
konstantin123 [22]
The answer is the vehicle. At the precise moment of the impact in a collision, there is the release of energy when a vehicle strikes another vehicle or another object. Earlier to an impact, a vehicle and everything inside the vehicle is traveling at whatever speed the vehicle had been going. As the collision continues, the vehicle slowly loses energy. However, the vehicle occupants and any others items in the vehicle continue to move forward at the same speed as the vehicle had been traveling prior to impact.
