Answer:
v = √(2gh)
Explanation:
Given:
Δy = h
v₀ = 0
a = g
Find: v
v² = v₀² + 2aΔy
v² = (0)² + 2gh
v = √(2gh)
You can also prove this with conservation of energy.
PE = KE
mgh = ½mv²
v = √(2gh)
A.rock breaking and D movement below ground
Answer:
The cross-sectional area of the larger piston is 800 cm².
Explanation:
Given;
mass of the automobile, m = 4000 kg
force applied on the small piston, F₁ = 500 N
area of the smaller piston, A₁ = 10 cm²
load lifted by the larger piston, F₂ = 4000 x 10 = 40,000 N
Pressure experienced by each piston is given as;

Where;
A₂ is the cross-sectional area of the larger piston

Therefore, the cross-sectional area of the larger piston is 800 cm².
Ionising radiation (ionizing radiation) is radiation that carries enough energy to free electrons from atoms or molecules, thereby ionizing them. Ionizing radiation is made up of energetic subatomic particles, ions or atoms moving at high speeds (usually greater than 1% of the speed of light), and electromagnetic waves on the high-energy end of the electromagnetic spectrum.
The sentence that best explains a possible result of climate change on Earth is : (B). Extreme heat, flooding, and drought will each increase crop yields.
<h3>Meaning of climate change</h3>
A climate can be defined as the weather pattern that is prolonged or long term in a geographical area
Climate change can now be said to be the change in the weather pattern that has been sustained in a particular geographic area for a long period of time
In conclusion, The sentence that best explains a possible result of climate change on Earth is : (B). Extreme heat, flooding, and drought will each increase crop yields.
