Answer:
3 ohm
Explanation:
Given :
V=9V
And according to given question same current is flowing in both resistance that means resistance will connected in series
So,
R= R+R=2R
Now,
Applying ohm's law
Therefore, answer is 3 ohm
Explanation:
a)
The circumference of the path is:
C = 2πr
C = 2π (0.235 m)
C = 1.48 m
Velocity = displacement / time
v = 1.48 m / 1.95 s
v = 0.757 m/s
b)
1 rev / 1.95 s = 0.513 Hz
c)
1 rev / 1.95 s × (2π rad / rev) = 3.22 rad/s
Answer:
Q= 722.5 *10⁻¹² C
Explanation:
Conceptual analysis
For a parallel plate capacitor, we can use the following formula :
E= (Q) /(ϵ₀*A) Formula (1)
Where:
E: electric field between the plates ( N/C)
Q: Charge of the plates (C)
ϵo : vacuum permittivity ( C²/ N.m²)
A : area oh the plates (m²)
Known data
A = 1.2 m²
E= 68 N/C
ϵo= 8.8542*10⁻¹² ( C²/ N.m²)
Problem development
We apply the formula (1) :
Q= (68) (8.8542*10⁻¹²)(1.2)
Q= 722.5 *10⁻¹² C
We would have earthquakes and tsunamis, i think, i don't really know?!?
It would probably be nice to use the brakes
