A rock on the moon has a mass of 17kg, what is the mass if this same rock on earth?

Physics
1 answer:
NISA [10]3 years ago
6 0

Mass is an intrinsic property of the rock.  The mass doesn't care where it is, and it makes no difference where the rock happens to be at the moment ... its mass doesn't change.

17kg of mass is 17kg .  If it's 17kg on the moon, it's <em>17kg</em> on Earth.

2. Explain the mechanism by which AC (alternating current) through the primary circuit of a transformer produces an alternating
atroni [7]

Explanation:

A transformer consists of core of soft iron (a material that can be easily magnetized/demagnetized), to which two coils are attached at both ends.

An alternating current in the primary coil produces a magnetic field around the coil, magnetizing the iron core; therefore, the same magnetic field produces a magnetic flux in the secondary coil.

Since the AC current in the primary coil is variable, then the magnetic field also changes, so the magnetic flux through the secondary coil changes over time; therefore, an electromotive force (and so, a current) is induced in the secondary coil, according to Faraday-Newmann-Lenz:

\epsilon= - \frac{d\Phi}{dt}

where

\epsilon is the induced emf

\frac{d\Phi}{dt} is the rate of change of magnetic flux through the secondary coil

We notice that this mechanism would not work if the current in the primary coil is a DC current: in fact, a DC current has always a constant value, so there is no change in the magnetic field, therefore no change in the magnetic flux through the secondary coil and no emf induced.

Consider a swimmer that swims a complete round-trip lap of a 50 m long pool in 100 seconds. What is the swimmers average speed a
Neporo4naja [7]

Answer:

The average speed is 1 m/s

The average velocity is 0

Explanation:

Given;

length of the pool, L = 50 m

time taken for the motion, t = 100 s

The total distance = 50 m + 50 m

The total distance = 100 m

The average speed = total distance / total time

                                  = 100 / 100

                                  = 1 m/s

The average velocity = change in displacement / change in time

change in displacement = 50 m - 50 m = 0

The average velocity = 0 / 100

The average velocity = 0

Who created the theory of general relativity?:

The answer would be: Albert Einstein.

Albert Einstein developed the general relativity theory (gravitation). 

The year he developed the general relativity theory or (GR) was back in 1907 and 1915. Then many other contributions after 1915.
