P=change in E/t
Change in E=p*t
=15*3
=45
The answer is 45J.
Answer:
magnitude of net magnetic field at given point is

Explanation:
As we know that magnetic field due to a long current carrying wire is given as

here we we will find the magnetic field due to wire which is along x axis is given as

r = 2 m
now we have

into the plane
Now similarly magnetic field due to another wire which is perpendicular to xy plane is given as

r = 2 m
now we have

along + x direction
Since the two magnetic field is perpendicular to each other
So here net magnetic field is given as


2 Ways Acceleration can be changed are:
i) Increasing or decreasing the velocity of a moving object.
ii) Change of direction of the moving object.
Snells law. The ratio of the sine of the angle of refraction and the sine of the angle of incidence are always constant.n1sine0 = n2sine0
Answer:
Explanation:
The acceleration of an object is given by the formula
a = v²/r
The acceleration of the object is bound to increase, if and only if the following are changed as well.
The mass of the object is increased,
The speed of the object is increased,
The radius of the object is contrarily decreased
Taking another look at the formula, we see that if we increase the speed of the object, it increases the acceleration. And since the radius is in the denominator, it has to be reduced for the acceleration to increase
