Climate change is the reason for a lot of factors such as:
Heat-trapping Greenhouse Gases And The Earth's Climate
Greenhouse Gases
Reflectivity or Absorption of the Sun's Energy
Changes in the Earth's Orbit and Rotation
Variations in Solar Activity
Changes in the Earth's Reflectivity
Volcanic Activity
There's a lot more that I could list, but hopefully this will do.
As it is pushed deeper, the buoyant force on the jar will decrease. The correct option is B
<h3>What is buoyant force ?</h3>
The upward force applied to an object that is fully or partially submerged in a fluid is known as the buoyant force. Upthrust is another name for this upward thrust. A body submerged partially or completely in a fluid appears to shed weight, or to be lighter, due to the buoyant force.
The fluid under which an object is submerged exerts pressure, which is what generates the buoyancy force. Because a fluid's pressure rises with depth, the buoyancy force is always upward.

Answer:
Alpha is the least penetrating radiation listed below.
Gamma is the most penetrating radiation in the given list.
These rays can be used to detect cancer, sterilizing the medical instrument, smoke detector, etc.
Radiation emitted from the radioactive elements also have very harmful. They affect the living being a lot. Waste from the nuclear reactor also contains harmful radiation which causes Land pollution if not disposed of properly.
Answer:
a) 16m/s b) 192m
Explanation:
v1=32m/s a=-2m/s^2 t=8s v2=? d=??
a) I will use this equation v2= v1 + a*t
v2= 32m/s + -2m/s^2 * 8s
v2= 32m/s + -16m/s
v2= 16m/s
b) v2^2=v1^2 + 2ad
rearranging
v2^2-v1^2=2ad
v2^2-v1^2/2= a d
v2^2-v1^2/2a=d
16m/s^2 - 32m/s^2/ 2 x-2m/s^2 =d
d=192m
