Quick definition: fear appeal: making someone do something out of fear of something.
I think the way it's used is that doctors make people dear disease.
Answer:
D &B
Explanation:
Using Fleming right hand rule that States that if the fore-finger, middle finger and the thumb of left hand are stretched mutually perpendicular to each other, such that fore-finger points in the direction of magnetic field, the middle finger points in the direction of the motion of positive charge, then the thumb points to the direction of the force
We use the formula: p = E/c where E = hc / λ. hence, p = h/ λ. where h is the Planck's constant: 6.62607004 × 10-34 m2 kg / s and <span>λ is the wavelenght.

a) p = <span>6.62607004 × 10-34 m2 kg / s / 0.1 x10^-9 m = 6.62607 x 10-24 m kg/s
</span>b) p = 6.62607004 × 10-34 m2 kg / s / 3 x10^-2 m = 2.20869 <span>x 10-32 m kg/s
</span>b) p = 6.62607004 × 10-34 m2 kg / s / 2 x10^-9 m = 3.3130 <span>x 10-25 m kg/s</span>
7.11x 10⁶J
Explanation:
Given parameters:
Speed of light = 3 x 10⁸m/s
Mass of object = 23.7g = 0.0237kg
Unknown:
Energy = ?
Solution:
From Einstein's equation, we see that mass and energy are equivalent using the expression below:
E = mc²
Substituting the parameters:
E = 3 x 10⁸ x 0.0237 = 7.11x 10⁶J
