Answer:
Explanation:
We are given that
Charge=q=
Potential difference=V=3 V
We know that
Work done=
Using the formula
Work done by charge to move from the negative terminal to the positive terminal of battery=
J
Work done by charge to move from the negative terminal to the positive terminal of battery=
Wood i think could be wrong
Answer:
Explanation:
Magnetic field at a a point R distance away
B = μ₀ / 4π X 2I / R where I is current
Magnetic field due to one current
= 10⁻⁷ x 2 x 24 / 1 x 10⁻³
48 x 10⁻⁴ T
Magnetic field due to other current
= 10⁻⁷ x 2 x 24 / 3x 10⁻³
16 x 10⁻⁴ T
Total magnetic field , as they act in opposite direction, is
= (48 - 16 ) x 10⁻⁴
32 x 10⁻⁴ T .
Answer:
meter per second square
Explanation:
Given
Height ,h 
m
Radius, r 
m
Distance travelled, 
m
Since, the stone is released and it falls towards the sky, its initial velocity is zero
As per equation
, we will evaluate "t"
Substituting the given values in above equation, we get
Velocity
centripetal acceleration
How do we find the Average Speed ?
The Average Speed is the distance traveled for the object, divided by the elapsed time taken to travel that distance, so the formula is :
<em>S = D / T</em>
where S = Average Speed, D = Distance, and T = Times
Here the object is the ball, the distance is 9 meters and the time elapsed for the ball to roll down the street is 3.5 seconds. Applying the formula we get :
S = 9 / 3.5 ≈ 2.6 metres per second
The ≈ symbols (which is the <em>wavy equal sign</em>) means we can't write the exact result, because there is an infinite quantity of numbers after the decimal point. So we need to give an approximation, since the result is 2.57142857142857...etc. we choosed to round up the result to 2.6.
