Answer:

It is observed that when a compass is brought near a current carrying conductor the needle of compass gets deflected because of flow of electricity. This shows that electric current produces a magnetic effect.

A simple pendulum having a length of 1.02 m and a mass of 6.66 kg undergoes simple harmonic motion when given an initial speed o
attashe74 [19]

Answer:

<em>Time period of pendulum is 2.02 s.</em>

Explanation:

A <em>simple pendulum</em> is a device which consists of mass m hanging from the string of length L attached to the some point.When displaced and released its swings back and forth with periodic motion.

The time period of pendulum is defined as time taken by the pendulum to complete one full oscillation . it is denoted by T.

By <em>Huygens law of period of pendulum</em>,

T = 2π\sqrt{\frac{L}{g} }   eqn 1

where L is the length of pendulum,

          g is acceleration due to gravity

<em>Period of pendulum is independent of the mass of pendulum,</em>

<em />

Substituting values in eqn 1

T = 2π \sqrt{\frac{1.02}{9.8\\} }

T =   2.02 s

<em>Time period of pendulum is 2.02 s.</em>

___________ currents are most often used in the wiring of new buildings and homes, while _____________ currents are the type sto
yarga [219]

Answer:

Alternating; direct.

Explanation:

Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.

Mathematically, Ohm's law is given by the formula;

V = IR

Where;

V represents voltage measured in voltage.

I represents current measured in amperes.

R represents resistance measured in ohms.

Alternating currents are most often used in the wiring of new buildings and homes, while direct currents are the type stored in batteries and fuel cells.

Basically, the direction of an alternating current changes periodically.
