Answer:
At 5km/hr; Hypnotist travels with a higher speed.
Explanation:
Let hypnotist be H while Raul be R.
Given the following data;
Distance H = 5km
Time H = 1 hour
Distance R = 5km
Time R = 2 hours
To find the their respective speed;
a. For H;
Speed = distance/time
Speed H = 5/1
Speed H = 5km/hr
b. For R;
Speed = distance/time
Speed R = 5/2
Speed R = 2.5 km/hr
Therefore, hypnotist travels with a higher speed.
Answer:
243 N
Explanation:
The formula for electromagnetic force is F= Kq1q2/r^2
where r is the distance between the charges, if the distance between the charges is reduced by 1/3 then F will increase by 9 [(1/3r)^2 becomes 1/9r which is 9F] so 27*9 is 243N
A soft metal core made into a magnet by the passage of electric current through a coil surrounding it.
Answer:
In particle physics, a lepton is an elementary particle of half-integer spin (spin 1⁄2) that does not undergo strong interactions.[1] Two main classes of leptons exist: charged leptons (also known as the electron-like leptons or muons), and neutral leptons (better known as neutrinos). Charged leptons can combine with other particles to form various composite particles such as atoms and positronium, while neutrinos rarely interact with anything, and are consequently rarely observed. The best known of all leptons is the electron.
