Answer:
0.0109 m ≈ 10.9 mm
Explanation:
proton speed = 1 * 10^6 m/s
radius in which the proton moves = 20 m
<u>determine the radius of the circle in which an electron would move </u>
we will apply the formula for calculating the centripetal force for both proton and electron ( Lorentz force formula)
For proton :
Mp*V^2 / rp = qp *VB ∴ rp = Mp*V / qP*B ---------- ( 1 )
For electron:
re = Me*V/ qE * B -------- ( 2 )
Next: take the ratio of equations 1 and 2
re / rp = Me / Mp ( note: qE = qP = 1.6 * 10^-19 C )
∴ re ( radius of the electron orbit )
= ( Me / Mp ) rp
= ( 9.1 * 10^-31 / 1.67 * 10^-27 ) 20
= ( 5.45 * 10^-4 ) * 20
= 0.0109 m ≈ 10.9 mm

Answer:
weight on Venus = 604.15 N
weight on Venus = 252.01 N
Explanation:
Given:
Weight on the earth , W = 150 lbs
now,
1 lbs = 4.45 N
thus,
W = 150 × 4.45 = 667.5 N
now, mass on the earth, m = 667.5/9.8 = 68.11 kg
now,
⇒ weight on Venus,
the acceleration due to gravity on venus = 8.87 m/s²
thus,
weight on Venus = mass × acceleration due to gravity on venus
or
weight on Venus = 68.11 × 8.87 = 604.15 N
⇒ weight on mars,
the acceleration due to gravity on mars = 3.70 m/s²
thus,
weight on Venus = mass × acceleration due to gravity on venus
or
weight on Venus = 68.11 × 3.70 = 252.01 N
The principles of stoichiometry are based upon the law of conservation of mass.
Answer:
a,= 1m/second. b,= 0m/ second ( constance,no movement)
