Answer:
Explanation:
We shall apply concept of impulse to solve the problem .
Impulse = force x time
impulse = change in momentum
force x time = change in momentum
initial speed u = 24 km/h = 6.67 m /s
final speed v = 65 km/h = 18.05 m /s
change in momentum = m v - mu
= m ( v-u )
= 1350 ( 18.05 - 6.67 )
= 15363 kg m/s
F x 18 = 15363
F = 853.5 N .
Can someone help me with a question? At the local ski park, James earns 519.36 for working 32 hours. Create a double number line to identify the amount of money he would make for 1, 8 and 40 hours of work?
Answer:
c. probablistic view of nature.
Explanation:
According to the problem of particle in a box in one dimension. If the particle energy E is taken less than the height of the barrier V.
Then with the help of classical mechanics it can be prove that the particle can not cross the barrier but according to the quantum mechanics, there is a small but a finite probability to cross the barrier.
Therefore by the above discussion it can be concluded that quantum mechanics can be thought as a probablistic view of nature.
Answer:
464.69 m
Explanation:
First car
Second car
Distance = Speed × Time
Here, the time taken and the distance traveled will be the same
Equating the two equations
So, the first would have to move 
in order to overtake the second car.
