Answer: a) Qo=550 *10^-6 C; b) Io=0.18 A; c) τ=3 ms
Explanation: In order to explain this problem we have to consirer the capacitor expresion given by :
C=Q/V then Q=C*V
the initial charge of the capacitor is:
Qo= 5*10^-6*110=550 μC
When the capacitor is connected to a resistor the stored charge is consume at the resitance as a current (dQ/dt):
The charge as a function of time is given by;
Q(t)= Qo*e(-t/τ) where τ is the equal R*C and represent the time constant.
the we have that the current is:
I=dQ/dt= (Qo/τ)*e(-t/τ)=(Qo)/(R*C)*e(-t/R*C)
Io=(Qo/τ)=(550*10^-6)/(600*5*10^-6)=0.18 A
IF there is no friction against the moving object (impossible in real life),
then it takes NO force to keep the object moving at a constant speed
in a straight line.
It takes force only to CHANGE the object's motion ... speed it up, slow
it down, or change its direction.
A because unit means one, i’m almost sure of that
Answer:
d. a large region outside Jupiter occupied by its magnetic field and filled with high-energy charged particles.
Explanation:
A magnetic field is generated by the movement of a charged particle in the space around it. For the case of Jupiter its magnetic field is created by the liquid metallic hydrogen in its core.
So the magnetosphere is just the magnetic field around a planet, which interacts with high-energy charged particles (for example: Cosmic Rays).
Magnetospheres protect planets from the extreme radiation coming from stars or another interstellar source.
Answer:
Explanation:
Given that,
Small piston Hydraulic piston has an area
A1 = 0.01m²
If the force applied is 250N is applied to the small piston at an area of 0.05 m²
Then,
F2 = 250 N and A2 = 0.05m²
Then, applying pascal principle,
Pressure at small area = pressure are bigger area
P1 = P2
F1 / A1 = F2 / A2
F1 / 0.01 = 250 / 0.05
F1 / 0.01 = 5000
Cross multiply
F1 = 5000 × 0.01
F1 = 50 N
