Which ramp is going to make the ball travel down faster?
The 2nd ramp because it is steeper and would give the ball a faster push caused by gravity than the 1st ramp.
To solve this problem it is necessary to apply the concepts related to the concept of superposition and the fringe separation for double slit experiment.
The equation can be written as

Where
= Distance between fringes
x = distance between slits and screen
d = Distance between slits
= Wavelength
Our values are given as
d= 0.08mm
x =3m

In this way replacing in the equation,




Therefore the distance between the fringes is 2.37cm
PART B) For the case in which it is submerged in water it is necessary to apply the relationship of the fringes with the index of refraction therefore



Copper(I) chloride, commonly called cuprous chloride, is the lower chloride of copper, with the formula CuCl.
Answer:
4.25 s
Explanation:
Given:
angular acceleration'α'= 1.8 rad/s²
angle 'θ'= 45 rad
time 't'= 4s
initial angular velocity '
'=0
as we know that,
θ=
t + 
45 = 4
+ (0.5 x 1.8 x 16)
45- 14.4 = 4 
30.6 = 4 
= 7.65 
Next is to find t by using the equation
=
+ 
7.65= 0 + (1.8)
= 7.65/1.8
= 4.25 s
Therefore, At the start of 4s interval the motion is at 4.25 second
Answer:
True
Explanation:
Charts are the most accurate way to measure most things. For example, a chart can help you understand how the population of the world has changed since 1998.
