Answer:
ξ = 0.00845020162 V or 8.4 mV
Explanation:
Magnetic flux measures the total magnetic field that passes through a known area. Magnetic flux describe the effect of magnetic field in a given area. Mathematically,
magnetic flux (Ф) = BA cos ∅
where
A = test area
B = magnetic field
before the flip
Ф = Bπr²N
N = number of turn
magnitude of induced emf = N |ΔФ/Δt|
ξ = 2Nπr²B/dt
ξ = 2 × 22 × π × (1.02/2)² × 0.000047/0.2
ξ = 44 × π × 0.51² × 0.000047/0.2
ξ = 44 × π × 0.2601 × 0.000047/0.2
ξ = 0.0005378868 × 3.142/0.2
ξ = 0.00169004032/0.2
ξ = 0.00845020162 V or 8.4 mV
A roller coaster is stopped on a track. When the engineer presses a launch button on the coaster, the coaster moves forward. Explain this change in terms of balanced and unbalanced forces.
Answer:
A. 26.17 B. 1.17 C. 30.86 D. 5.86
Explanation:
To calculate force, use the formula force equals mass times acceleration, or F = m × a. Make sure that the mass measurement you're using is in kilograms and the acceleration is in meters over seconds squared. When you've solved the equation, the force will be measured in Newtons.
Examples:
<span>Air </span>
<span>Blood </span>
<span>Mouthwash </span>
<span>Rubbing Alcohol </span>
<span>Peroxide </span>
<span>Hand-sanitizer </span>
<span>Perfume </span>
<span>Some bath gels </span>
<span>Coffee </span>
<span>Chicken or Beef Broth </span>
<span>Body Spray </span>
<span>Natural Oils </span>
<span>A heterogeneous mixture is a mixture where the components of the mixture are not uniform or have localized regions with different properties. </span>
<span>Examples: </span>
<span>Rocks </span>
<span>Oil and water </span>
<span>Soup </span>
<span>Pizza </span>
<span>Copper sulfate </span>
<span>Salsa </span>
<span>Chicken soup </span>
<span>Cottage cheese
