Answer: Option (a) is the correct answer.

Explanation:

When we say something to a person related to his performance in a task, office, school, college etc then it is known as a feedback.

A feedback can be positive or negative.

For example, a student's performance was not up to the mark so his teacher remarked as capable of doing better by putting some more efforts. This remark represents a positive feedback.

Thus, we can conclude that feedback is always given to you by other people.

g Two identical metal spheres (small enough to be treated as particles) each with a mass of 3.1 × 10−3 kg are hung from separate
gogolik [260]

Answer:

Explanation:

Let q be the charges on each spheres , 2d be the   distance between them in equilibrium , T be tension in the string and F be the force of repulsion between them

F = k q² /4d²

For equilibrium

T sin15 = F

T cos 15 = mg

tan15 = F / mg

F = mg tan15

k q² /4d² = mg tan15

k q² = 4d² x mg tan15

= 4 x( .7 sin15)² x 3.1 x 10⁻³ x 9.8 x .2679

= 1.068 x 10⁻³

q = .3444 x 10⁻⁶ C

no of electrons

=  .3444 x 10⁻⁶  / 1.6 x 10⁻¹⁹

= 215.25 x 10¹⁰

Please help me with this question...
Yakvenalex [24]
1) In first case, both the objects(hand & tea) are in direct contact, so heat will flow by the process of "Conduction" 

2) In this case, objects are not in direct contact, and heat is transferring from one to another by "Convection"

3) Here, there is no contact between the objects (our body & sun), sun light with heat comes through the process of "Radiation"

In short, Your Answers would be:
1) Conduction
2) Convection
3) Radiation

Hope this helps!

A long wire is known to have a radius greater than 4.0 mm and to carry a current uniformly distributed over its cross section. i
ollegr [7]

Magnetic field outside it due to long wire is given by

B = \frac{u_o i}{2 \pi r}

Magnetic field due to long wire inside wire at any point

B = \frac{u_o i r}{2 \pi R^2}

Now the ratio of two magnetic field is given by

\frac{B_{in}}{B_{out}} = \frac{r_1/R^2}{1/r_2}

\frac{0.285}{0.200} = \frac{4*10}{R^2}

1.425 = \frac{40}{R^2}

R = 5.3 mm

A car is initially moving at 20 m/s east and a little while later it is moving at 10 m/s north. Which of the following best desc
Nina [5.8K]

Answer:d

Explanation:

Given

First car is moving  towards east with velocity 20 m/s

\vec{v_1}=20\hat{i}

then it turns towards north then velocity is  

\vec{v_2}=10\hat{j}

suppose car takes t sec to change its path so average acceleration is given by

a=\frac{v_2-v_1}{t}

a=\frac{1}{t}(10\hat{j}-20\hat{i})

So average  acceleration is towards North of west.

A roller coaster car of mass m = 300 kg is released from rest at the top of a 60 m high hill (position A), and rolls with a negl
Triss [41]

Answer:

The principle of conservation of energy and angular momentum

Explanation:

At point A, the car experienced maximum of potential energy

As it moves down the hill, the potential energy decreases while the kinetic energy increases.

The maximum kinetic energy of the car is needed for the attainment of enough centripetal force to help the car move through the loop without falling .
