The best description of a grizzly bear’s habitat is:
A habitat is the natural surrounding or place where an organism lives, grows and competes with other organisms for resources. It is a physical area.
There are three major types of habitat which includes:
A grizzly bear is a subspecies of brown bear and is resident in the northern plains of America and their habitat is a physical location where they live.
Therefore, the correct answer is option D

Answer:
I found this question elsewhere on brainly and the answer was verified. Here it is!
Explanation:
Grizzly bear habitats is the habitat or the physical space where the bear lives. Grizzly bears can be found in many different habitats from dense forests to subalpine meadows, arctic tundra and open plains. We can also conclude that all of the bears live in grizzly bear's habitat in order to survive.
Answer:
The hottest objects with temperatures in the millions of Kelvins, give off most of their radiation in the form of X-rays and gamma rays.
Explanation:
The electromagnetic (EM) spectrum contains radio waves, microwaves, infrared light, visible light, ultraviolet light, X-rays and gamma-rays. All these different types of radiation are made up of photons having specific wavelengths and different amounts of energy. In the EM spectrum, the photons of radio waves have the lowest energy and the energy of photons increases through microwaves, infrared, visible light, ultraviolet, X-rays, and the photons of gamma-rays have the highest energy (the energy of photons is measured in electron volts).
All warmer objects such as stars, planets, etc emit photons having a specific range of wavelengths and it depends on the surface temperature of those objects. The very hot objects with temperatures in the millions of Kelvins or more mainly emit photons with shorter wavelengths, such as gamma rays and X-rays while cooler objects emit radiation such as infrared or radio waves, having longer wavelengths.
The ultraviolet radiation has the energy in the range of a few electron volts to about 100 eV. The energy of X-ray photons is in the range of 100 eV to 100 keV and the energy of gamma-rays is greater than 100 keV. The nuclear explosions, radioactive decay, the hottest and most energetic objects in the universe such as neutron stars, supernova explosions, etc produce gamma rays.
Objects with temperatures in the millions of Kelvins emit most of their radiation in the X-ray and gamma-ray parts of the electromagnetic spectrum.
Objects with temperatures in the millions of Kelvins primarily give off most of their radiation in the X-ray and gamma-ray parts of the electromagnetic spectrum. As an object's temperature increases, the wavelengths of radiation it emits become shorter. This phenomenon is described by Wien's displacement law.
At lower temperatures, such as those found on Earth or in stars like our Sun, objects emit most of their radiation in the visible and infrared parts of the spectrum. However, as temperatures rise to millions of Kelvins, the emitted radiation shifts to shorter wavelengths, eventually falling into the X-ray and gamma-ray regions.
In the X-ray and gamma-ray parts of the electromagnetic spectrum, radiation has extremely high energy and short wavelengths. These types of radiation are associated with the very high temperatures and intense energy found in extremely hot objects, such as the cores of massive stars, supernovae, and certain high-energy astrophysical phenomena. Scientists use X-ray and gamma-ray telescopes to study these extreme environments and the radiation they emit.

6001 pounds is slightly more than 3 tons. This is because, in the comparison scale, 1 ton is equal to 2000 pounds. So, 3 tons equals 6000 pounds.
The student is asking which is more, 3 tons or 6001 pounds. To determine this, we need to understand the relationship between tons and pounds. We know that 1 ton is equivalent to 2000 pounds. So, 3 tons would be equivalent to 3*2000 = 6000 pounds.
Hence, comparing 6001 pounds with 3 tons, or effectively 6000 pounds, 6001 pounds is slightly more than 3 tons.

Gravitational potential energy increases; kinetic energy increases.
B.
Kinetic energy equals gravitational potential energy.
C.
Kinetic energy increases; gravitational potential energy decreases.
D.
The mass of the ball is required to answer this.
The ball originally contains potential energy and no kinetic energy, therefore we can use the theory of conservation of mechanical energy. Its total energy, which is made up of the KE and PE, is constant and equal to its starting PE as it falls. Thus, option C is correct.
As the ball falls toward the ground, its gravitational potential energy is transformed into kinetic energy. The kinetic energy of the ball will increase as it accelerates until it collides with something. The ball's collision generates kinetic energy, which is transformed into several forms of energy.
As it rises, the ball's speed slows until the very apex of its motion, where it briefly pauses. At the peak, it accelerates at -9.8 m/s2.
Therefore, A ball is thrown up into the air, yet although though it rises into the air, the direction, and velocity of the ball are actually downward.

The amount of electrical energy used by the television is given by:
where P is the power of the device and t is the time.
The power of the television is P=315 W, while the total time is
If we substitute these numbers into the formula, we find the energy:
so, the correct answer is
(1) 5.67 × 10^5 J
