Parallax of the stars is created by :
B. Different locations of Earth in its orbit
Parallax refer to the position of an object (in this case, a star) that will look different if we view it from different positions
hope this helps
Answer:
So after stretching new resistance will be 0.1823 ohm
Explanation:
We have given initially length of the wire 
Radius of the wire 
Resistance of the wire initially 
We know that resistance is equal to 
,here 
is resistivity, l is length and A is area
From the relation we can say that 
Now length of wire become 6.75 m
Volume will be constant
So 
So 
So 
Calculate the circumference of the circular path of the wheel by the equation,
C = 2πr
where C is the circumference,
r is the radius
Substituting the known values,
C = 2(π)(0.487 m) = 3.06 m
Then, period of the motion will be determined by dividing the number of rotations done,
T = (3.06 m) / (5.75 /s) = 0.53 s
<em>ANSWER: 0.53 s</em>
Explanation:
u = 0m/s
v = 30m/s
a = 2m/s²
Using Kinematics, we have v = u + at.
Therefore t = (v - u) / a
= (30 - 0) / (2) = 15 seconds. (B)
