<h2>Answer</h2>
Option A that is 8.8 × 10^3 m/s
<h2>Explanation</h2>
The magnetic field B is defined from the Lorentz Force Law, and specifically from the magnetic force on a moving charge. It says
Field-strength = BVqsinΔ
<h2>v = E/B </h2>
Since field are perpendicular so sin90 = 1
v = 4.6/10^4 / 5.2
v = 8846.15 m /s
The speed at which electrons pass through the selector without deflection = 8846.15 m /s
Answer:
Explanation:
Orbital velocity is the speed that a body that orbits around another body must have, for its orbit to be stable. For orbits with small eccentricity and when one of the masses is almost negligible compared to the other mass, like in this case, the orbital speed is given by:
Where M is the greater mass around which this negligible body is orbiting, r is the radius of the greater mass and G is the universal gravitational constant. So:
Answer:
The answer to your question is a = -1.85 m/s² the acceleration is negative because it is coming to stop.
Explanation:
Data
vo = 25 m/s
t = 13.5 s
a= ?
vf = 0 m/s
Formula
vf = vo + at
solve for a
a = (vf - vo)/t
Substitution
a = (0 - 25) / 13.5
Simplification
a = -25/13.5
Result
a = -1.85 m/s²
Answer:
85.5 km/h
Explanation:
= time interval for first phase = 14 min = 
h = 0.233 h
= time interval for second phase = 46 min = 
h = 0.767 h
= average speed for the entire trip = 74 km/h
= average speed in first phase = 36 km/h
= average speed in second phase
= distance traveled in first phase
= distance traveled in first phase
average speed is given as
km/h
Answer:
False
Explanation:
Solid water (ice) has a lesser density than liquid water. Hence, the statement is false.
