Answer:
N = 1036 times
Explanation:
The radial probability density of the hydrogen ground state is given by:






N = 1035.57
N = 1036 times
The answer is, "the speed of the current is 5 miles per hour."
To calculate the speed of the current,
let's assume speed of current = xmph. Time taken to travel from one pier to another with the current = 100/(20+x)h
But the time taken to travel from one pier to another with the current, which is given is = 4 hours. So, 4=100/(20+x) 80+4x = 100
4x = 20
x = 5 Thus, the speed of the current is 5 miles per hour.
Maria throws two stones from the top edge of a building at a speed of 20 m/s, The time is mathematically given as
t=4.5 sec.
<h3>How much later is it before the second stone hits?</h3>
Generally, the equation for speed is mathematically given as
V = u+at
Therefore
0 = 22-9.8xt.
t = 22 /9.8 sec
t = 2.24489.
The same time will be taken from max^m height to point O
The extra time is taken
t=4.49 sec.
t=4.5 sec.

Answer:
<em>a) 3344 N</em>
<em>b) 3344 N</em>
Explanation:
This is the complete question
1100 kg car pushes a 2200 kg truck that has a dead battery. When the driver steps on the accelerator, the drive wheels of the car push against the ground with a force of 5000 N. Rolling friction can be neglected. A. What is the magnitude of the force of the car on the truck? Express your answer to two significant figures and include the appropriate units. B. What is the magnitude of the force of the truck on the car?
Mass of the car = 1100 kg
Mass of the truck = 2200 kg
Force exerted on the ground by the car = 5000 N
The total mass in the system = 1100 + 2200 = 3300 Kg
Total force in the system = 5000 N
Recall that the force in the system = mass x acceleration
therefore,
5000 = 3300 x a
Total acceleration in the system = 5000/3300 = 1.52 m/s^2
The force on the truck individually fro the car, will be the product of this acceleration and its mass
Force on the truck = 2200 x 1.52 = <em>3344 N</em>
b) Force on the car From the truck will be equal to this force but will act in the opposite direction.
Force on the car from the truck is <em>3344 N </em>
Answer:
T2 = 662°c Q(in) = 911kj W(out) = 180kj
Explanation:
1. Firstly, we find the mass from the initial volume and specific volume from steam table A-5 for given pressure and state.
M = V(1)/a(1) = 0.6/0.7183(kg)
Where a(1) = specific volume
M = 0.835kg
The work is determined from the final pressure and the volume change that occurs when it is reached.
W = P2(V2 - V1)
W = P2V2
= 300×0.6kg = 180kg
Therefore, to get the final temperature and final pressure, the final temperature is determined fro steam table A-6 using interpolation.
T2 = T1* + T2*-T1*/a2*-a1* (a2-a1*)
T2 = 600 + 700-600/1.4958-1.34139 (1.43746-1.34139)
T2 = 662°c
2. The final internal energy can be determined in the same way just like the initial ones were done. From A-5 on steam table given the pressure
The heat Q(in) = ∆u + W(out)
= m(U2-U1) + W(out)
= 0.835(3412.3-2536.8)kj
+ 180
Q(in) = 911kj
