Difference is that science is a particular discipline or branch of learning, especially one dealing with measurable or systematic principles rather than intuition or natural ability or science can be scion while physics is the branch of science concerned with the study of properties and interactions of space, time etc

Physics is branch of science which deals with the properties of matter and their energies. And coming to science it is a systemic enterprise that builds and organizes knowledge in t eatable explanations and predictions about the universe.

Answer:

e) indicated that the speed of light is the same in all inertial reference frames.

Explanation:

In 18th century, many scientists believed that the light just like air and water needs a medium to travel. They called this medium <em>aether</em>. They believed that even the space is not empty and filled with aether.

Michelson and Morley tried to prove the presence and speed of this aether through an interference experiment in 1887. They made an interferometer in which light was emitted at various angles with respect to the supposed aether. Both along the flow and against the flow to see the difference in the speed of light. But they did not find no major difference and thus it became the first proof to disprove the theory of aether.

It thus proved that the speed of light remains same in all inertial frames.

Also, it became a base for the special theory of relativity by Einstein.

A circular loop of radius 11.7 cm is placed in a uniform magnetic field. (a) If the field is directed perpendicular to the plane

Mama L [17]

Answer:

Magnetic field, B = 0.199 T

Explanation:

It is given that,

Radius of circular loop, r = 11.7 cm = 0.117 m

Magnetic flux through the loop, $\phi=8.6\times 10^{-3}\ T/m^2$

The magnetic flux linked through the loop is :

$\phi=B.A$

$\phi=BA\ cos\theta$

Here, $\theta=0$

$B=\dfrac{\phi}{A}$

$B=\dfrac{\phi}{\pi r^2}$

$B=\dfrac{8.6\times 10^{-3}}{\pi (0.117 )^2}$

B = 0.199 T

So, the strength of the magnetic field is 0.199 T. Hence, this is the required solution.

From an apple tree 2 metres high, a 100g mass apple fell of the tree, what work did it do?

Likurg_2 [28]

Answer:

When an apple falls from the tree to the ground, its energy of position (stored as gravitational potential energy) is converted to kinetic energy, the energy of motion, as it falls. When the apple hits the ground, kinetic energy is transformed into heat energy.

OLEGan [10]

One major obstacle to developing good human relations is that man is fearful by nature. There are risks involved in developing human relations, and humans are mostly too scared to take those risks. Majority of humans are comfortable with staying in their own comfort zones, and would like to avoid the hassle of getting to know others.

If the magnetic field a perpendicular distance r to the left of a current-carrying wire is 10 T, what will the net magnetic fiel

larisa86 [58]

Answer:

30 T

Explanation:

The magnetic field due to first wire at point A is $B_1=\frac{\mu _0i}{2\pi r}$

Magnetic field due to second wire at point A is $B_2=\frac{\mu _02i}{2\pi r}$

As the current flows in opposite direction in both the wire so net magnetic magnetic field at point A is $B=B_1+B_2=\frac{\mu _0i}{2\pi r}+\frac{\mu _02i}{2\pi r}=\frac{\mu _03i}{2\pi r}$

So net magnetic field $B=3B_1=3\times 10=30T$ as $B_1$ is given as 10 T in question
