Answer:
C
Explanation:
The potential energy decreases because Magnet 1 moves against the magnetic force. If it was increased it would be kinetic
Answer:
1.63 
Explanation:
The equation 
would be used where:
g = acceleration due to gravity
G = universal gravitational constant (6.67408 × 
)
M = mass
R = radius.
assuming the values following both 10s of the mass and radius are their exponents, which is a little confusing, the values given would simply be substituted.
Anyone can correct me if I'm wrong.
Answer:
Hey mate.....
Explanation:
This is ur answer.....
<em>The formula to calculate force is: force = mass x acceleration, or F = m x a, where force and acceleration have both magnitude and direction.</em>
Hope it helps!

Answer:
f = 6.37 Hz, T = 0.157 s
Explanation:
The expression you have is
y = 5 sin (3x - 40t)
this is the equation of a traveling wave, the general form of the expression is
y = A sin (kx - wt)
where A is the amplitude of the motion, k the wave vector and w the angular velocity
Angle velocity and frequency are related
w = 2π f
f = w / 2π
from the equation w = 40 rad / s
f = 40 / 2π
f = 6.37 Hz
frequency and period are related
f = 1 / T
T = 1 / f
T = 1 / 6.37
T = 0.157 s
