Answer: 1.64 *10^19 electrons
Explanation: In order to the explain this problem we have to consider the following:
The current= charge/time; so
as the electrons move in the tungsten wire we have:
0.526 C/s= N electrons per second* charge of electron=
N electrons/s= 0.526/1.6*10^-19= 3.28 *10^18 electrons/s
Then, during 5 seconds will pass:
3.28 *10^18 electrons/s*5 5s= 1.64 *10^19 electrons
Answer:
Distance, s = 399.42 m/s
Explanation:
It is given that,
Initial velocity of drag racer, u = 0
Final velocity of drag racer, v = 407 km/hr = 113.056 m/s
Acceleration,
Third equation of motion is :
s is the distance traveled
s = 399.42 m/s
So, the distance traveled during this acceleration is 399.42 m/s. Hence, this is the required solution.
Answer:
Car C
Explanation:
The length of the deformed crumple zone is significantly longer in Car C, so the average deceleration was lower. The lower acceleration puts less stress on the dummy. Car C better protected the dummy.
Hi,
The answer is D, Gravitational.
