Answer:
A
I say this because exponential growth takes place when a population per Capita growth stays the same
Answer:
The speed and direction of the two players immediately after the tackle are 3.3 m/s and 53.4° South of West
Explanation:
given information:
mass of fullback, = 92 kg
speed of full back, = 5.8 to south
mass of lineman, =110 kg
speed of lineman, = 3.6
according to conservation energy,
assume that the collision is perfectly inelastic, thus
initial momentum = final momentum
= '
m₁v₁ = (m₁+m₂)'
' = m₁v₁/(m₁+m₂)
= (92) (5.8)/(92+110)
= 2.64 m/s
= '
m₂v₂ = (m₁+m₂)'
' = m₁v₁/(m₁+m₂)
= (110) (3.6)/(92+110)
= 1.96 m/s
thus,
' = √'²+'²
= 3.3 m/s
then, the direction of the two players is
θ = 90 - tan⁻¹('/')
= 90 - tan⁻¹(1.96/2.64)
= 53.4° South of West
According to the research, the correct option is b. The main difference between both is that kinetic energy involves motion, and potential energy involves position.
<h3>What are kinetic energy and potential energy?</h3>
Kinetic energy refers to that energy that a body or system possesses due to its movement and like any other type of energy, it can be converted into heat and other forms of energy.
On the other hand, potential energy is the energy that is capable of generating work as a result of the position of the body and is classified according to the forces that give rise to it, such as gravitational, elastic, chemical, among others.
Therefore, we can conclude that according to the research, the correct option is b. The main difference between both is that kinetic energy involves motion, and potential energy involves position.

1. Ice melting involves a change from a solid to a liquid and the substances maintain the properties of water because the molecules never change. 2. Water boiling is a physical change as water molecules vibrate faster, they enter the gas phase and become water vapor.
Answer:
Option C, acting as waves and particles
Explanation:
Light has dual nature because it acts both as a wave and particle. It has high energy particle i.e photons and it also behave as an electromagnetic wave. This property of light is studied under the quantum mechanics. Einstein also proved that light is a stream of photons possessing both electrical and magnetic properties.
Hence, option C is correct
