Total Money =$32
Cost of each ticket =$4
Let number of tickets be x
So
$4x=$32
X=32/4
X=$8
Answer:
33.33 rad / s
Explanation:
Linear velocity = 35 m/s
Radius = 1.05 m
The relation between the linear velocity and the angular velocity is given by
Linear velocity = radius × angular velocity
Angular velocity = linear velocity / radius
Angular velocity = 35 / 1.05
= 33.33 rad/ s
Answer:
Explanation:
As the source is situated on x - axis , it must be situated in between the two listeners .
So the x coordinate of source is
(-7 + 3 )/2
= - 2 m
The equation of the wave- front will be that o a circle having centre at (-2,0)
and radius = distance between -2 and 3 , that is 5 m
equation of circle
=( x+2 )² + y² = 25
It cuts y axis when x = 0
Putting x = 0
4 + y² = 25
y² = 21
y = + √21 , or - √21
Answer:
Electric flux in a) , b) and c) is same which is 0.373 × 10 ⁶ N m²/C
Explanation:
given,
surface charge (q) = 3.3 × 10⁻⁶ C
to calculate electric flux = ?
a) radius = 0.76 m
area of sphere = 4 π r²
electric flux =
electric flux =
flux = 0.373 × 10 ⁶ N m²/C
electric flux in the other two cases will also be same as electric flux is independent of area
so, Electric flux in a) , b) and c) is same which is 0.373 × 10 ⁶ N m²/C
