Answer:
10V = 1mA(1Ω + Rs)
Rs=10-1
Rs=9Ω
Explanation:
See the attached picture for diagram.
Answer:50.39 m/s,
40.46 m
Explanation:
Given
launch angle
Range=240 m
We know that Range 

u=50.39 m/s
(b)maximum height of projectile is given by


H=40.46 m
Halogens therefore react most vigorously with Group 1 and Group 2 metals of all main group elements.
Answer:
433 mph
Explanation:
We know that
...Eq(1)
Here,
Distance =1,592 miles
Time=3.68 hours
Putting the value of distance and Time in the Eq(1) We get
Velocity =

therefore Average velocity is 433 mph
