Ok so we know:
The time (t) is 18seconds
The acceleration (a) is 2.2m/s2
The displacement (r) is 660
Using the equation
With 'u' being the initial velocity we want, we get:
So:
So:
So the original/initial velocity was 16.8666 or 16.87 m/s
Hope this helped
That's true.
If the line is perpendicular to the y-axis, then it's horizontal,
and parallel to the x-axis.
Every point on the line has the same y-coordinate. If the point (-5, 1)
is on the line, then all the points (any number, 1) are also on it.
The equation of the line is
[ y = 1 ] .
Answer is B.
Because velocity is vector quantity, so magnitud and direction are needed to define it.
Since velocity means the speed(magnitude) of some object in a given direction, so it’s units are usually measured by meters/ seconds
Answer:
I = 3.82 x 10^(−7) A
Explanation:
The formula for magnetic field at the centre of a loop is given as;
B = μI/2R
Where μ is a magnetic constant with a value of 12.57 × 10^(−7) H/m.
I = current
R = Radius = 16/2 = 8cm or 0.08m
B = 3.0×10^(−12) T
So making I the subject of the formula, we obtain ;
I = 2RB/μ
Thus, I = [2 x 0.08 x 3.0×10^(−12)]/12.57 × 10^(−7)
I = 3.82 x 10^(−7) A
