Answer:
in the ball
Explanation:
potential energy is where an object has energy, always, but it isn't always moving, and when you drop the ball, it has kinetic energy.
Answer:
C
Explanation:
vectors are any quantities that have both magnitude and direction
therefore both inertia and weight are both vectors
You are working for a manufacturing company, which is mathematically given as
<h3>What is the
value of m that will place the
movable bead in equilibrium at x-a a ....?</h3>
a)
Generally, the equation for the force of equilibrium is mathematically given as
F=2fcos\theta
Therefore
b)
By force equilibrium
Therefore
c)
x^2+a^2=(14/3)^{2/3}x^2
x=a/1.338
x=0.747a
d)
By force equilibrium

Answer:
52 m/s
Explanation:
Wavelength is the distance between two successive crests. Two crests make one circle hence 16 cycles are equal to 16 wavelengths. Each wavelength is equal to 208/16=13 m long
Speed of wave is given as the product of wavelength and frequency, expressed as
S=fw
Where f is the frequency and w is the wavelength
Substituting 13 m for w and 4 Hz for f then
S=4*13=52 m/s
Therefore, the speed is equivalent to 52 m/s
Answer:
5.6875 × 10^(10) electrons
Explanation:
To some this we will use the formula;
q = ne
Where;
q is charge
n is number of electrons
e is electron charge = 1.6 × 10^(-19) C
We are given q = -9.10 nc
1 nc = 10^(-9) C
Thus;
q = -9.1 × 10^(-9) C
Since q is negative, then e = -1.6 × 10^(-19) C
Thus;
-9.1 × 10^(-9) = n(-1.6 × 10^(-19))
n = -(9.1 × 10^(-9))/(-1.6 × 10^(-19))
n = 56875000000 electrons = 5.6875 × 10^(10) electrons
