Explanation:
In 1897, J.J. ... Thomson realized that the accepted model of an atom did not account for negatively or positively charged particles. Therefore, he proposed a model of the atom which he likened to plum pudding. The negative electrons represented the raisins in the pudding and the dough contained the positive charge.
Answer:
Power P=246.78 KW
Explanation:
Mass of Elevator=4710 Kg
Can carry load =1910 Kg
Total Mass m to be lifted =4710 kg + 1910 Kg =6620 kg
speed = 3.80 m/s ⇒ per second distance traveled (height h) = 3.80 m and time t = 1 s
Using formula of Power P = 
P = 
P= 6620kg × 9.81 m/s² × 3.80 m / 1s
P= 246780.36 W
P=246.78 KW
Answer:
“We have a brain for one reason and one reason only, and that's to produce adaptable and complex movements,” stated Wolpert, Director of the Computational and Biological Learning Lab at the University of Cambridge. ... The evidence for this is in how well we've learned to mimic our movements using computers and robots.
Answer:
14.47 m/s
Explanation:
The momentum must be preserved before and after the collision:
The total momentum before the collision
where 
are the masses of the car moving south and north, respectively, before the collision. 
is the velocity of the car moving South. We take the velocity to the North as the positive direction
The total momentum after the collision
where V = 5.22m/s is the velocity of both cars after the collision
We can equalize the 2 equations and plug in the numbers:
Comets are cosmic snowballs of frozen gasses, rock and dust that orbit the sun. When frozen, they are the size of a small town. When a comet's orbit brings it close to the sun, it heats up and spews dust and gasses that form a tail that stretches away from the sun fr millions of miles. There are probably billions of comets orbiting our sun in the Kuiper Belt and even more distant Oort Cloud. Comets have right for its name and had best to orbit the sun in the Kuiper Belt.
