Women are now allowed to participate in the Olympics. The original Olympic Games were open only to men.

Modern Olympic Games include many more events. The first Olympics included only a running event. Today, there are more than 20 different sports and almost 300 events.

The Olympics are held every two years, alternating between summer and winter. The ancient Olympics were originally held every four years in Olympia.

Athletes from countries around the world participate in the modern Olympics. The ancient Olympics consisted of athletes only from ancient Greece.

One kilowatt-hour (kWh) is the amount of work or energy generated when one kilowatt of power is supplied for a time of one hour.
Helga [31]

Answer:

The energy in one kilowatt-hour is 36\times10^{5}\ J

Explanation:

Given that,

Power = 1 kW

Time = 1 hour

One kilowatt-hour (kWh) is the amount of work or energy generated when one kilowatt of power is supplied for a time of one hour

We need to calculate the energy

Using formula of energy

E=p\times t

Where, P = power

t = time

Put the value into the formula

E=1\times10^{3}\times3600

E=36\times10^{5}\ J

Hence, The energy in one kilowatt-hour is 36\times10^{5}\ J

An α-particle has a charge of +2e and a mass of 6.64 × 10-27 kg. It is accelerated from rest through a potential difference that
zzz [600]

Answer with Explanation:

We are given that

Charge on alpha particle=q=2 e=2\times 1.6\times 10^{-19} C

1 e=1.6\times 10^{-19} C

Mass of alpha particle=m=6.64\times 10^{-27} kg

Potential difference,V=1.97\times 10^6 V

Magnetic field,B=3.49 T

a.Speed of alpha particle=v=\sqrt{\frac{2 qV}{m}}

By using the formula

v=\sqrt{\frac{2\times 2\times 1.6\times 10^{-19}\times 1.97\times 10^6}{6.64\times 10^{-27}}

v=1.38\times 10^7 m/s

b.Magnetic force,F=qvB=2\times 1.6\times 10^{-19}\times 1.38\times 10^7\times 3.49=1.5\times 10^{-11} N

F=1.5\times 10^{-11} N

c.Radius of circular path, r=\frac{mv^2}{F}

r= \frac{6.64\times 10^{-27}\times (1.38\times 10^7)^2}{1.5\times 10^{-11}}

r=0.084 m
