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.
A 59 kg sprinter, starting from rest, runs 47 m in 7.0 s at constant acceleration.?
What is the sprinter's power output at 2.0 s, 4.0 s, and 6.0 s?
Instantaneous Power is the force times velocity
P = Fv
Because the acceleration is constant, the force will be constant as well
F = ma
P = mav
for constant acceleration, the velocity at each time is found using
v = at
P = ma(at) = ma²t
find the acceleration using kinematic equation
s = ½at²
a = 2s/t²
a = 2(47) / 7.0²
a = 1.918 m/s²
P(2.0) = 59(1.918²)2.0 = 434.25 W = 0.43 kW
P(4.0) = 59(1.918²)4.0 = 868.51 W = 0.87 kW
P(6.0) = 59(1.918²)6.0 = 1302.76 W = 1.3 kW
I hope this helped.
The tangential velocity of the car is 124.5 m/s
Explanation:
The centripetal acceleration of an object in uniform circular motion is given by:
where
a is the acceleration
v is the tangential velocity
r is the radius of the circle
For the car in this problem, we have:
is the centripetal acceleration
r = 155 m is the radius of the turn
Solving for v, we find the tangential velocity of the car:

Firstly an atom has electrons , protons and neutrons. The protons are positively charged and the electrons are negatively charged and the neurons are neutral. So in a neutral atom the amount of protons equals to the amount of electrons. Thus the protons and neutrons can be called particles
Thrust adalah kekuatan atau dorongan. Ketika sistem mendorong atau mempercepat massa dalam satu arah, ada dorong (force) hanya besar dalam arah yang berlawanan. Dalam matematika dan fisika, ini dijelaskan oleh hukum kedua dan ketiga Isaac Newton. Dorong digunakan untuk menggambarkan seberapa baik jenis mesin berjalan. Hal ini dapat digunakan untuk berbagai jenis mesin seperti mesin roket, pesawat (baling-baling) mesin, dan mesin jet.
Thrust diukur dalam "pon dorong" di AS dan di Newton dalam sistem metrik. 4.45 Newton dorong sama dengan 1 pon dorong. Satu pon dorong adalah berapa banyak dorong yang dibutuhkan untuk menjaga satu pon objek tak bergerak melawan gaya gravitasi di bumi.
