Answer:
18.896ms-1
Explanation:
The tangential acceleration of the car= 0.747ms-2
The centripetal acceleration is given by v^2/r
0.747= v^2/r
V= √0.747*478= 18.896ms-1

Answer:
6.45 x 10^5 N/C
Explanation:
q = + e = 1.6 x 10^-19 C
m = 9.99 x 10^-27 kg
V = 13 kV = 13000 V
B = 1 T
Let v be the speed and E be the strength of electric field.
1/2 mv^2 = eV
v^2 = 2 e v / m
v^2 = (2 x 1.6 x 10^-19 x 13000) / (9.99 x 10^-27)
v = 6.45 x 10^5 m/s
As the charge particle is undeflected, the force due to magnetic field is counter balanced by the force due to electric field.
q E = q v B
E = v B = 6.45 x 10^5 x 1 = 6.45 x 10^5 N/C

Answer:
D) 19.8 lbs
Explanation:
1kg in household measurement is equal to 35.274 ounces. 35.274*9=317.466 ounces.
1kg is also equal to 2.205 lbs. 9*2.205=19.8416
9 kg is also equal to 9000 grams, but grams are not a part of the household measurement system
a) 9000 grams. b) 9000 ounces. c) 19.8 ounces. d) 19.8 pounds.
This leaves us with 19.8 lbs
