A synthetic element is one of 24 chemical elements that do not occur naturally on Earth: they have been created by human manipulation of fundamental particles in a nuclear reactor, a particle accelerator, or the explosion of an atomic bomb; thus, they are called "synthetic", "artificial", or "man-made". The synthetic elements are those with atomic numbers 95–118, as shown in purple on the accompanying periodic table:[1] these 24 elements were first created between 1944 and 2010. The mechanism for the creation of a synthetic element is to force additional protons onto the nucleus of an element with an atomic number lower than 95. All synthetic elements are unstable, but they decay at a widely varying rate: their half-lives range from 15.6 million years to a few hundred microseconds.

VLD [36.1K]

Answer:

Turns of the primary coil: 500

Current in the primary coil: Ip= 0.01168A

Explanation:

Considering an ideal transformer I can propose the following equations:

        Vp×Ip=Vs×Is

Vp= primary voltaje

Ip= primary current

Vs= secondary voltaje

Is= secondary current

        Np×Vs=Ns×Vp

Np= turns of primary coil

Ns= turns of secondary coil

From these equations I can clear the number of turns of the primary coil:

Np= (Ns×Vp)/Vp = (20×120V)/4.8V = 500 turns

To determine the current in the secondary coil I use the following equation:

Is= (1.4W)/4.8V = 0.292A

Therefore I can determine the current in the primary coil with the following equation:

Ip= (Vs×Is)/Vp = (4.8V×0.292A)/120V = 0.01168A

The potential (relative to infinity) at the midpoint of a square is 3.0 V when a point charge of Q is located at one of the corn
tester [92]

Answer:

12.0 V

Explanation:

Data :

Potential difference due to a single charge (+Q), E = 3.0 V

 

The Electric potential for the system of charges is given as:

E=\frac{1}{4\pi \epsilon_o}[\Sigma\frac{Q}{r}]

for single charge, E = 3.0 V = \frac{1}{4\pi \epsilon_o}[\frac{Q}{r}]  ->eq(1)

And for 4 charges:

E=\frac{1}{4\pi \epsilon_o}[4\frac{Q}{r}] -eq(2)

from eq(1) and (2) we have

E = 4 × 3.0 V = 12 V

A train left the station at 9:00am. The next stop was 629 km south. It
Aleks04 [339]

Explanation:

We need to calculate the time it had travelled first:

9:00 to 12:00 = 3 hours.

12:00 to 2:00 = 2 hours

Total travel time = 5 hours.

The formula for speed is distance ÷ time (Hence, the unit for speed is m/s, kph, mph, etc.)

= 629km ÷ 5 hours

= 125.8 km/hour ~ 125.8kph
