It takes 7.0s for a piece of wood to be falling from a tall building in the velocity of 68.6 m/s
<u>Explanation:</u>
v = u + at
68.6 ms^-1 = 0 ms^-1 + (9.8 ms^-2 x t)
t = 68.6 ms^-1 / 9.8 ms^-2
t = 7.0s
It takes 7.0s for a piece of wood to be falling from a tall building in the velocity of 68.6 m/s
Give me some answer choices and i will be happy to help
Answer:
Part A:
Part B:
Option B (Towards the South)
Explanation:
Part A:
Magnitude if electric field E:
E=Force/charge
Force=2.04×10−14 N
Charge=1.6×10−19 C
Part B:
Option B (Towards the South)
As electron is experiencing the force towards south,it means the direction of the electric field is towards the south because direction of field lines is from positive to negative, so proton is moving towards south it means negative charge is in south to which proton is attracted. So electric field is towards South.
The answer is A because the oryx in the picture are competing.
Answer:
Biodiversity.
Explanation:
The number of different species in a particular area is known as biodiversity. Blue whales, plants, different kind of animals, and micro-organism living in an ocean is the example of biodiversity. In biodiversity each specie has its own role. For example, if a biodiversity has large number of plants (species), it will have many type of crops.
