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:
Advantage:
It makes work faster and easier
Disadvantage:
The work to its very best
Explanation:
More people reduces the time spent on one work which makes easier to finish but the work might not be done to its very best because different people are doing the job
Answer:
im sure your already past this but it's E.
Explanation:
This is because in this case potential energy is linear to height, which means that the higher the more potential energy.
Answer:
option C
Explanation:
given,
Period of oxygen molecule = 6 s
number of molecule = 6 x 10²³
Area of wall = 2 cm²
speed of molecule = 400 m/s
mass of O₂ molecule = 5.344 × 10⁻²⁶ Kg
we know,
Δp= F Δt
Δp change in momentum
Δp = N.m.Δv
where N is the number of oxygen molecules strike a wall
Δv = v - (-v)= 2 v
Pressure,
P = 21376 Pa
P = 21.4 kpa
hence the correct answer is option C
Answer:
Increasing force tends to increase acceleration while increasing mass tends to decrease acceleration. Thus, the greater force on more massive objects is offset by the inverse influence of greater mass. Subsequently, all objects free fall at the same rate of acceleration, regardless of their mass.
If the mass increases, it's harder to accelerate
