Answer:
The equivalent resistance of the combination is 3.42 ohms.
Explanation:
We have,
8 ohms resistor is connected in parallel with a 6 ohms resistor. It is required to find the equivalent resistance of this combination.
For a parallel combination, the equivalent resistance is given by :
Plugging the values of R₁ and R₂, we get :
So, the equivalent resistance of the combination is 3.42 ohms.
Answer:
D
Explanation:
a weak base is the answer
Explanation:
It is given that,
Radius of curvature of the mirror, R = 1.54 cm
(a) We have to find the focal length of the mirror. The relationship between the focal length and the radius of curvature is given by :
f = focal length of the mirror
f = 0.77 cm
(b) The power of mirror is given by the reciprocal of focal length i.e.
Power, 
P = 1.29 diopters
Hence, this is the required solution.
Put your bet down on Choice 'A'. The others are just flat wrong.
Answer: I showed you all calculation . You did not attach any graph to question .
Explanation:
Lets first find Velocity
Vr=o m/s
Ve=?
a=1m/s²
t=2s
----------
a=(Vr-V)/t
1m/s²=Vr-0m/s/2s
2m/s=Vr
Lets find the time neeeded to stop :
a=1m/s²
Vs=2m/s
Vf=0m/s
a=(Vf-Vs)/t
t*1m/s²=2m/s
t=2 s
