Answer:
Explanation:
Let the velocity of deuteron be v then force on it in magnetic field
Bqv , B is magnetic field and q is charge on deuteron . This force will provide centripetal force for circular path so
mv² / r = Bqv m is mass of deuteron and r is radius of circular path
v = Bqr / m
(.5 x 1.6 x 10⁻¹⁹ x 55.6 x 10⁻² )/ 3.34 x 10⁻²⁷
= 13.31 x 10⁶ m /s
Answer:
(a) 0.942 m
(b) 18.84 m/s
(c) 2366.3 m/s²
(d) 0.05 s
Explanation:
(a) In one revolution, it travels through one circumference, 2πr = 2 × 3.14 × 0.15 m = 0.942 m.
(b) Its frequency, f, is 1200 rev/min = 
rev/s = 20 rev/s.
Its angular frequency, ω = 2πf = 2π × 20 = 40π
The speed is given by
v = ωr = 40π × 0.15 = 6π = 18.84 m/s
(c) Its acceleration is given by, a = ω²r = (40π)² × 0.15 = 2366.3 m/s²
(d) The period is the inverse of the frequency because it is the time taken to complete one revolution.
T = 1/20 = 0.05 s
Answer:

Physical science is the study of matter and energy, and the relationship between matter and energy.
E. The study of matter and energy, and the relationship between matter and energy
<u>Explanation:</u>
The study of issue and vitality and the associations between physicists concentrate such subjects as gravity, light, and time. Albert Einstein, a well known physicist, built up the Theory of Relativity.
Material science is the investigation of issue and vitality at all scales—from the littlest particles of the issue to the whole universe.
A geologist has practical experience throughout the entire existence of Earth. A sea-life scholar contemplates sea plants and creatures. A physicist ponders matter, vitality, and how they are connected.
There are three primary parts of science: physical science, Earth science, and life science. Physical science is the investigation of lifeless common items and the laws that administer them. It incorporates material science, science, and cosmology.
