Answer:
s= 8.28×10⁻¹⁶m
Explanation:
given
V= 2.25×10³V
from conservation of energy
mv²/2=qΔV
v=√(2qΔV/m)
v= √(2×1.6×10⁻¹⁹×2.25×10³/9.1×10⁻³¹)
=√7.9×10¹⁴m/s
=2.8×10⁷m/s
the deflection of electron beam is
S= gt²/2
recall t= d/v
s=g()²/2
s= ×9.8×(0.364/2.8×10⁷)²
s= 8.28×10⁻¹⁶m
Answer:
0.25hr
Explanation:
Given parameters:
Distance = 200km
Time = 2hrs
Now, let us find the rate which is the speed;
Speed =
Insert parameters:
Speed = = 100km/hr
Since the speed of Imamu = 2 x speed of Mosi = 200km/hr
Time taken = =
= 0.25hr
