Gravity Gravitational Force of Gravity
Answer:
B) more current.
Explanation:
When two lamps are connected in series then we have
now let the two lamps are identical
so we have
now the total resistance of the lamps is given as
now the current in that case is given as
Now when lamps are connected in parallel
net resistance of two lamps is given as
so now we have
so we have
so now the current through the battery will be
So current will be more when two lamps are connected in parallel
Answer: 2.55 joules, -9.81 joules, -12.36 joules
Explanation:
the parameters given from the question are :
mass (m) = 0.20 kg
height above water (h₁) = 1.3m
depth of the well (h₂) = 5m = -5m (the negative sign is there because it is a depth below the surface )
constant value for acceleration due to gravity (g) = 9.8 m/s
- potential energy (PE) before the stone is released = m x g x h₁
PE₁ = 0.20 x 9.8 x 1.3 = 2.55 joules
- potential energy (PE) when it reaches the bottom of the well= m x g x h₂
PE₂ = 0.2 x 9.8 x (-5) = -9.81 joules
- change in potential energy = PE₂ - PE₁
= -9.81 - 2.55 = -12.36 joules
Answer:
geothermal energy
Explanation:
the energy is obtained from the heat within the surface of earth
Answer:
a) 1.51Vm/s
b)Id=0.134A
Explanation:
(a) The time rate of change of electric flux between the plates can be computed by using:
where Ic is the current of the capacitor, e0 is the dielectric permittivity of vacuum and A is the area of the capacitor.
(b) The displacement current coincides with capacitor current:
Id = 0.134A
hope this helps!!
