Hello Lauren, The answer to this question is D:Plate boundaries.
Have a wonderful day:).
Answer:
Amplitude.
Explanation:
The amplitude of a transverse wave is the measurement of it's maximum displacement.
It is also the maximum distance that a point moves in a transverse wave when measured from its position of rest.
Answer:
Vector quantity
Explanation:
-A vector quantity refer to the physical quantity characterized by the presence of both magnitude as well as direction.
-The direction is given as North.
-The magnitude is given as 80 blocks.
#Hence, this is a vector quantity.
Answer:
The ratio of the refractive indices of the liquids is 1.22
Solution:
Critical angle for A and B interface,
Critical angle for A and B interface,
Now,
From the relation in between the critical angle and refractive index:
(1)
where
n = rafractive index
= critical angle
Thus
For AB interface:
For AC interface:
Thus the ratio of the refractive indices of these liquids can be given as:
F = ma
Force = mass * acceleration
Switch the question to be:
Mass = force/acceleration
34 Newtons/4 m/s = m
M = 8.5 kg
Answer should be: The mass is 8.5 kg
