Answer:
1)X(t)=Xo±Vo(t)±*a
2)a(t)=
Explanation:
1)with this formula you can determine the position of the object studied when you have an accelerated, or deaccelerated motion, where Xo its your beginning position, and Vo is your beginning speed, and t is the difference of time between the final time and the initial time. The signs of the equation (+ or -) depends if its displacement its increasing on time, or diminishing, it means : positive speed, and acceleration, and in the oposite case negative speed and acceleration respectively.
2)this formula lets you know the variation of speed at each time (considering its constant), so if you have a constant variation of speed along a determined time, then you can use it.
This formula is used in uniformly accelerated rectilinear motion
I believe you're talking about displacement. It's a directional vector that depicts the movement of a point between two instances.
Answer:
326.4 mC
Explanation:
The relationship between charge, capacitance and voltage in a capacitor is given by
where
C is the capacitance
Q is the charge
V is the voltage
In this problem, we have
C = 34 mF is the capacitance
V = 9.6 V is the voltage
Re-arranging the equation and substituting the numbers, we find the charge stored in the capacitor:
I think the correct answer from the choices listed above is the first option. It is the magnetic fields present that causes the compass to move. <span>A compass reacts with the Earth's magnetic field, however, if another piece of metal is near of the needle magnet's magnetic field the needle will deflect toward the metal.</span>
