Answer:
From the given choices, the healthy snack that can provide protein after physical activity is the third option, yogurt. Yogurts are derived from fermentation of raw materials by the healthy bacteria, usually of lactobacillus origin. Other items in the choices are not able to provide protein.

Answer:
0.03 m
Explanation:
Mirrors work on the principle of reflection.
Reflection occurs when a ray of light hits a surface and bounces back into the origina medium at a different angle.
We can solve this problem by using the magnification equation:
where
y' is the size of the image
y is the size of the object
q is the distance of the image from the mirror
p is the distance of the object from the mirror
Here we have:
y = 0.10 m is the height of the object
p = 0.20 m is the distance of the object from the mirror
q = -0.06 m is the distance of the image from the mirror (negative because it appears behind the mirror, so it is a virtual image)
Solving for y', we find the size of the image:
And the positive sign indicates that the image is upright.
Answer:
Explanation:
Initial magnetic flux = magnetic field x area
= 4.4 x 5 x 10⁻³
= 22 x 10⁻³ weber
Final magnetic flux
= 1.32 x 5 x 10⁻³
= 6.6x 10⁻³ weber
change in magnetic flux = 15.4 x 10⁻³
emf induced = change in flux / time
= 15.4 x 10⁻³ / 22 x 10⁻³
= .7 V
current in bracelet = emf / resistance
= .7 / .02
= 35 A
b )
power = volt induced x current
= .7 x 35
= 24.5 W .
