Answer:
distance- 1400 m
displacement- 100 m before the finish line
Explanation:
The direction would be dependent on the direction of the current through the circuit. But for this, you can use the right hand rule to determine the direction of the magnetic field. <span>The </span>right hand rule<span> states that: to determine the direction of the magnetic force on a positive moving charge, ƒ, point the thumb of the </span>right hand<span> in the direction of v, the fingers in the direction of B, and a perpendicular to the palm points in the direction of F.</span>
Answer:
There are 934 excess electrons on the ball with charge -1.4944*10^(-16).
Step-by-Step Explanation:
A ball will usually be neutral and have no charge on it.
If it is negatively charged, it means there are excess electrons on it.
If we know the charge on the ball, we can count the excess no. of electrons.
We know that the charge on the ball = c = -1.4944*10^-16
Charge of one electron = e = 1.6*10^-19
Charge of n electrons on the ball = ne = c
⇒ n = c/e
n = (-1.4944*10^-16)/(1.6*10^-19)
n = 934 electrons
Answer:
Explanation:
v² = u² + 2as
v = 0
u = 96 / 3.6 = 26.7 m/s
0² = 26.7² + 2a100
a = -3.5555555... ≈ -3.6 m/s²
the negative sign indicated the acceleration vector opposes the (assumed positive) initial velocity vector direction.
