Answer:
3 cm
Explanation:
According to the question,
.
.
.
Now the approximate slit's image width is equal to width of central maxima.
And width of central maxima is twice the width from center to first maxima
So,
.
Substitute all the variable in above equation.
.
.
Answer: Right.
According to traffic rules, one should keep one's vehicle in the right side of lane if intends to turn right in near future. The purpose of this is the road safety. Also, it saves time. It would be difficult to take a right turn from the left side of the lane. It would cause inconvenience to others as well.
Answer:
The answer is ε = 1.5*εo
Explanation:
we have to:
I = R*C
also:
C´ = (A*ε)/α
C = (A*εo)/α
So:
I´ = ε*I
Given by the exercise:
I´/I = 1.5 (50% of increase)
Thus:
ε/εo = 1.5
Clearing ε:
ε = 1.5*εo
In the x-direction, the frictional force is the lone force pro
tem on the player
The formula is: Fnet = ma
f = ma
In the y-direction, N, the normal force turns up and mg, the force of gravity turns
down
N = mg (since there is no speeding up in the vertical direction)
f = -uN
=> f = -umg
-umg = ma
=> a = -ug
Using the kinematics equation:
d = (vf^2 - vi^2) / 2a
d = vi^2 / 2ug
d = 4.6^2 / 2(4.508)
d = 2.35 m/s
