Answer:
The relationship between temperature and kinetic energy is directly proportional.
Explanation:
The temperature is directly proportional to the kinetic energy of the gas molecules. We know that kinetic energy is the energy due to the motion and when gas molecules absorbs heat, they move with more speed and the kinetic energy of particles increases as a result.
According to the kinetic theory of gases
K = 3/2RT/Na
Where K is the average kinetic energy of gas molecules, T is the temperature of the gas, Na is Avogadro's number and R is the universal gas constant.
Answer:
The maximum magnetic field strength is 833.33 T
Explanation:
The maximum magnetic field strength is equal:
Where
E = electric field strength = 2.5x10¹¹V/m
c = speed of the light = 3x10⁸m/s

Explanation:
Answer:
It goes down.
The water level remain the same.
Explanation:
This can be explained using Archimedes principle which states that a body fully or partially submerged in a fluid is acted by an upward bouyant force which is equal to the weight of the fluid the body displaced.
The wood will only sink if the weight of the wood is greater than the weight of the fluid the wood displaced, but the weight of the wood is equal to the weight of fluid displaced, therefore the wood will float.
Therefore, the weight of the wood is the same as the weight of the fluid displaced, so the wood will be at the same level as the water.
If the iron is removed, the level of the water goes down because iron weight is bigger than the water displaced and it tends to increase the water level but since it is removed, the water level will decrease.
Answer:
Biodiversity decline continues due to a rapidly expanding human population. Habitat is damaged in order to meet growing needs for agriculture, urban development, water and materials. Fish, wildlife and plants are overharvested, despite mounting evidence that many harvesting practices are unsustainable.
