Answer:
Static friction acts on stationary objects while kinetic friction acts on those in motion. Static friction is always greater or equal to kinetic friction. This can explain why objects often take more force to get in motion than it takes to continue their motion.
Answer:
Test (OR you may decide to call it study)
Answer:
a) l = 24 cm
b) υ = 2.5 × 10⁹ Hz
Explanation:
given,
wavelength of microwave = 12 cm
length of microwave
= 2 × λ
= 2 × 12
l = 24 cm
microwave is an electromagnetic wave speed is 3 × 10⁸ m/s
v = υ λ
υ =
υ =
υ = 2.5 × 10⁹ Hz
Answer:
(a) The convex mirror image, is always upright at all positions, while images formed by concave mirrors are always inverted when the object distance from the mirror is more than the mirrors focal length.
(b) An upright image is not seen for object at a distance from a concave mirror further than the focal length of the mirror, which is the spoon in the question
Therefore, the location of her eyes of approximately, 30 cm, from the mirror is more than the mirror's focal length
Explanation:
