I believe that your acceleration would be 4 m/s
Answer:
Its not zero anywhere
Explanation:
The magnetic field B at a distance r due to a long conductor carrying current I is given as
B= μol/2pi r
so the net magnetic field due to the current is not zero anywhere
<u>We are given:</u>
the initial height of the object (h) = 100 m
initial velocity (u) = 0 m/s
we will let the value of g = 10 m/s/s
<u>Speed of the object just before hitting the ground:</u>
From the third equation of motion:
v² - u² = 2ah (where v is the final velocity)
replacing the variables, we get:
v² - (0)² = 2(10)(100)
v² = 2000
v = 10√20 = 44.7 m/s
Therefore, the speed of the object just before hitting the ground is 44.7 m/s
Answer:
1)So, the mass(m) of the tv is 75kg and the scale(weight)=825 N therefore you devide the weight by the mass which is equal to 11m/s^2
2)First things first you need to know the gravitational force here on earth which is 9.8(approximately 10) I will sove for 9.8 and 10 so you can choose
the fish has a mass of 2.4kg and the gravity= 9.8 so the weight is equal to the mass*gravity= 23.52
now if you use 10 as the gravity= 2.4*10= 24
3) here the weight is 250N and gravity is 9.8(10) so we just devide the weight by the gravity= 250/9.8= 25.51
250/10= 25( if gravity is 10)
Answer:
In a nutshell, units of A and B are ![\frac{1}{[l]^{2}}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B%5Bl%5D%5E%7B2%7D%7D)
and ![\frac{[l]}{[t]}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Bl%5D%7D%7B%5Bt%5D%7D)
, respectively.
Explanation:
From Dimensional Analysis we understand that 
and 
have length units (![[l]](https://tex.z-dn.net/?f=%5Bl%5D)
) and 
have time units (![[t]](https://tex.z-dn.net/?f=%5Bt%5D)
). Then, we get that:
![[l] = A\cdot [l]^{3}](https://tex.z-dn.net/?f=%5Bl%5D%20%3D%20A%5Ccdot%20%5Bl%5D%5E%7B3%7D)
(Eq. 1)
![[l] = B\cdot [t]](https://tex.z-dn.net/?f=%5Bl%5D%20%3D%20B%5Ccdot%20%5Bt%5D)
(Eq. 2)
Now we finally clear each constant:
![A = \frac{[l]}{[l]^{3}}](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%7B%5Bl%5D%7D%7B%5Bl%5D%5E%7B3%7D%7D)
![A = \frac{1}{[l]^{2}}](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%7B1%7D%7B%5Bl%5D%5E%7B2%7D%7D)
![B = \frac{[l]}{[t]}](https://tex.z-dn.net/?f=B%20%3D%20%5Cfrac%7B%5Bl%5D%7D%7B%5Bt%5D%7D)
In a nutshell, units of A and B are and , respectively.
