Answer:
Explanation:
Given,
Magnetic field
Radius
The angle between the area vector and magnetic field is 0 degree, because the direction of area vector is always perpendicular to the plane.
A product is something sold by an enterprise to its consumers or customers. Product development is the set of activities beginning with the perception of a market opportunity and ending in the production, sale, and delivery of a product. The characteristics of a successful product development includes;
-product quality
-product cost
-development cost
-development time and
-development capability
Answer:
is proved.
Explanation:
The magnetic field in the long current carrying wire is,
Here, I is the current, B is the magnetic field.
Now, by using cylindrical coordinates for the divergence of B.
Put the value of B in above equation.
Hence, it is prove that for a long current I carrying wire magnetic field divergence that is .
Answer:
Yes, it will float.
Explanation:
It is given that,
A liquid has a density of 0.85 g/cm³.
We know that, the density of water is 1 g/cm³.
The density of the liquid is less than that of water. If the density of the liquid is less than that of water, it will float in it. Hence, if you pour some of the liquid into a glass of water, it will float.
