Answer:
1000 m/s
Explanation:
Given that
Mass of the ball, m = 10 g = 0.01 kg
Charge of the ball, q = 2 C
Field strength of the field, E = 5 N/C
Acceleration of the ball, a = ? m/s²
We know the the equation holds,
F = qE, on substituting, we have
F = 2 C * 5 N/C
F = 10 N
Also, we know that
F = ma, and as such,
a = F / m, on substituting we have
a = 10 N / 0.01 kg
a = 1000 m/s²
Therefore, the acceleration of the ball is 1000 m/s²
Explanation:
The inductive reactance 
is given by
Solving for f, we get
Answer: 30.34m/s
Explanation:
The sum of forces in the y direction 0 = N cos 28 - μN sin28 - mg
Sum of forces in the x direction
mv²/r = N sin 28 + μN cos 28
mv²/r = N(sin 28 + μcos 28)
Thus,
mv²/r = mg [(sin 28 + μ cos 28)/(cos 28 - μ sin 28)]
v²/r = g [(sin 28 + μ cos 28)/(cos 28 - μ sin 28)]
v²/36 = 9.8 [(0.4695 + 0.87*0.8829) - (0.8829 - 0.87*0.4695)]
v²/36 = 9.8 [(0.4695 + 0.7681) / (0.8829 - 0.4085)]
v²/36 = 9.8 (1.2376/0.4744)
v²/36 = 9.8 * 2.6088
v²/36 = 25.57
v² = 920.52
v = 30.34m/s
It would take the bicyclist 9 seconds to move 36m.
Answer:
The answer is 13 however make sure if they ask for a certain measurement like meter answer it by saying 13 meters.
Explanation:
This basically turns into basic algebra if you know the formula for work. The formula for work is W=F*d
Here are the variables that you know 650J=50N*d so you need d.
All you do is divide 650J by 50N and you get a total of 13 (meters since I don't know what they want you to put it in).
