A piano is hanging by a rope. Beside it are two vectors. The vector pointing upward is longer and labeled F Subscript T Baseline
RideAnS [48]

The net force acting on the piano is 500N

<h3>When is two vectors Parallel ?</h3>

There will be parallel vectors when two vectors are moving in the same direction or opposite direction.

Given that a piano is hanging by a rope. Beside it are two vectors. The vector pointing upward is longer and labeled F_{T} = 6,000 N. The second vector is downward and labeled F_{g} = 5,500 N which will be negative because it will be acting downward.

Let the net force be F_{N}. Then,

F_{N} = F_{T} + F_{g}

F_{N} = 6000 - 5500

F_{N} = 500 N

Therefore, the net force acting on the piano is 500N

When a current of 2.0A flows in the 100-turn primary of an ideal transformer, this causes 14 A to flow in the secondary. How man
kati45 [8]

Answer: The correct option is D) 14

Explanation:

A transformer is a device used for stepping- up or stepping- down an alternating voltage. It has both primary and secondary windings. Energy is usually supplied through the primary coil and delivered through the secondary coil in a transformer. Using the equation:

Ns= lp

Np= Is

Where Ns--> number of turns in secondary coil

Np--> number of turns in primary coil

Is--> current flow in secondary coil

Ip--> current flow in primary coil.

Therefore Ns= Np Ip/Is

Substituting from the question

Ns= 100×2/14

Ns= 200/14

Ns = 14.28 which is approximately 14 turns in the secondary coil.

Determine the quantity of charge on a plastic tube which has been rubbed with animal fur and gained 3.8 x 10^9 electrons
PSYCHO15rus [73]

The quantity of charge carried by the plastic tube is -6.08 x 10^-10 C.

<h3>What are electrons?</h3>

Electrons are negatively charged particles that are found in the atom. The magnitude of charge carried by an electron is about -1.6 × 10^-19 C. We must note that the negative sign indicates that the electron is negatively charged.

The quantity of charge carried by the tube is obtained from;

q =ne

q = 3.8 x 10^9 × ( -1.6 × 10^-19 C)

q = -6.08 x 10^-10 C

a suitcase with a mass of 2 kg has a weight of 18 n what is the acceleration due to gravity on that planet
Leni [432]
The formula for finding acceleration due to gravity in this case is g=w/m where g is acceleration due to gravity, w is weight and m is mass.g=18/2, g=9
Therefore the acceleration due to gravity on that planet is 9m/s2.
