Time - 0.792s
acceleration - 9.8m/s2
vertical height - ?
remember that height is in meters
so from the acceleration
9.8 = x
----
0.792*0.792
cross multiply
=6.147m approximately 6.2m
Answer:
Maximum magnetic field will be 0.288 T
Explanation:
We he given number of turns in solenoid N = 23800
Length of the solenoid l = 1 m
So number of turns per unit length in the solenoid ![n=\frac{N}{l}=\frac{23800}{1}=23800](https://tex.z-dn.net/?f=n%3D%5Cfrac%7BN%7D%7Bl%7D%3D%5Cfrac%7B23800%7D%7B1%7D%3D23800)
Maximum current in solenoid i = 100 A
Magnetic field due to solenoid is equal to ![B=\mu _0ni](https://tex.z-dn.net/?f=B%3D%5Cmu%20_0ni)
![B=4\pi \times 10^{-7}\times 23800\times 100=0.288T](https://tex.z-dn.net/?f=B%3D4%5Cpi%20%5Ctimes%2010%5E%7B-7%7D%5Ctimes%2023800%5Ctimes%20100%3D0.288T)
As the current is maximum so magnetic field will be also maximum
So maximum magnetic field will be 0.288 T
Answer:
Reproducible data is one component of the precision of a measurement or test method and accurate data is one of the components of data quality.
OR
The data which is accurate means it can't be changed further is called accurate data. while, The data which is changed again and again is called reproducible data. Reproducible data is one component of the precision of a measurement or test method and accurate data is one of the components of data quality.
<span>So this question based on doppler effect
Here apparent freq = freq of sound *(speed of sound-speed of observer)/(speed of sound-speed of source)
given
freq of sound=2000
speed of observer= 20
speed of source= 30
taking speed of sound as 343 m/s
apparent freq = 2000 [343 - 20] / [343 - 30] = 2063.90 Hz</span>
Electrical resistance resists the rate of flow of charge (Current), so when resistance increases, current will decrease
In short, Your Answer would be "True"
Hope this helps!
