Answer:
I would say D
Explanation:
The dependent variable is the thing that is measured when the independent variable is changed by us.
The independent variable would be the type of disinfectant so after you use the disinfectant you would measure the amount of bacteria meaning the answer would be D
Answer:
313.8 m/s
Explanation:
Momentum p must be conserved.
The momentum before the collision:
The momentum after the collision:
Solving both equations:
(9.39 x 10⁹ sec) x (1 day / 8.64 x 10⁴ sec)
= (9.39 / 8.64) x 10⁵ days
= 108,680.56 days
How about to understand the nature of reality itself? Also, we live in the universe, so it might be useful to understand how it works.
The magnitude of the magnetic field on the axis of the ring 5 cm from its center is 143 pT.
The radius of the nonconducting ring is R = 10 cm.
The ring is uniformly charged q = 10 μC.
The angular speed of the ring, ω = 20 rad/s
The ring is x = 5 cm from the center of the ring.
Now,
R = 10 cm = 0.1 m
q = 10.0 μC = 10 × 10⁻⁶ C
x = 5 cm = 0.05 m
The magnetic field on the axis of a current loop is given as:
B = [ μ₀ IR² ] / [4π(x² + R²)^{3/2} ]
Now, I = q / [2π/ω]
So, the magnitude of the magnetic field which is directed away from the center is:
B = [ μ₀ ωqR² ] / [4π(x² + R²)^{3/2} ]
B = [ μ₀ (200) (10 × 10⁻⁶) (0.1)² ] / [4π((0.05)² + (0.1)²)^{3/2} ]
B = 1.43 × 10⁻¹⁰ T
B = 143 pT
