Edison's education is most unique and relevant.
1. The first teacher he had was his mother
2. He found vital lessons and was influenced greatly by the book of R.G. Parker called School of Natural Philosophy
3. Another educating piece he had was a book entitled The Cooper Union for the Advancement of Science and Art
His style of learning was though reading books on a variety of subjects, a self-educating environment that fosters independent learning which can be useful through his life.
Answer:
Due to energy loss while collision ball will not reach to same height while if there is no energy loss then in that case ball will reach to same height
Explanation:
As we know that initially ball is held at height h = 40 cm
So here we can say that kinetic energy of the ball is zero and potential energy is given as
now when strike with the ground then its its fraction of kinetic energy is lost in form of other energies
So the ball will left rebound with smaller energy and hence it will reach to height less than the initial height
While if we assume that there is no energy loss during collision then in that case ball will reach to same height again
Answer:
53.36 m.
Explanation:
Initial velocity of the toolbox u = 0
acceleration due to gravity g = 9.8 m s⁻²
time t = 3.3 s
height of roof h = ?
h = ut + 1/2 g t²
= 0 + .5 x 9.8 x 3.3²
= 53.36 m.
In series circuit, Req = R₁ + R₂ + R₃ + ···
In parallel circuit,
<h3>Q7.</h3>
total resistance in the upper branch = R₂ + R₃ = R₂ + 2
R₂ + 2 = 12
R₂ = 10Ω
<h3>Q8.</h3>
Req = 1.7Ω
Answer:
Based on the scientific notation ,
4.372896 x10^-7 is the answer.
