Answer:
the velocity of the water flow is 7.92 m/s
Explanation:
The computation of the velocity of the water flow is as follows
Here we use the Bernouli equation
As we know that

= 7.92 m/s
Hence, the velocity of the water flow is 7.92 m/s
We simply applied the above formula so that the correct value could come
And, the same is to be considered
Titan is the largest moon in Saturn.
Answer:
2.89 hours
Explanation:
given :
Vo = 72 km/h
Vt = 90 km/h
S = 234 km
find : the time taken (t) = ?
solution :
2.a.s = Vt² - Vo²
2.a.(234) = 90²- 72²
468.a = 8100 - 5184
= 2916
a = 2916/468 = 6.23 km/h²
so,
t = (Vt-Vo) /a
= (90-72)/ 6.23
= 18/ 6.23
= 2.89 hours
Answer:
W = 12 kJ
Explanation:
We have,
Voltage of a battery is 12 V
Charge supplied by the battery is 1000 C
It is assumed to find the work is done by the battery in moving the charge. The work done is given in terms of voltage as :

or
W = 12 kJ
So, the work of 12 kJ is done by battery in moving charges.
