Answer:
60 Ohms
Explanation:
Ohms law states that the voltage in the circuit is directly proportional to the current through the circuit components and expressed as
V=IR
Where V is the voltage, I is current and R is resistance
Making R the subject of the formula then
Substituting 3.0V for V and 0.05 A for I then
Therefore, resistance is 60.0 Ohms

ANSWER:
a)Angle = 79°
b)Resultant vector = 10.2m/s
a)Use the pythagoras trigonometry ratios to obtain the angle..,
Vertical(opposite) = 10
Horizontal(adjacent) = 2
tan theta = 10/2...,where theta is representing the angle.
;theta = 79°
b) Resultant vector(R)...we use the pythagoras to calculate it,
Where our resultant vector is the hypothenus...,
R^2 = 10^2 + 2^2
R^2 = 104
Hence,
;Resultant vector = square root of 104
= 10.2 m/s
Answer:
2.7 x 10^-14 m
Explanation:
E =8.8 MeV = 8.8 x 1.6 x 10^-13 J
q = 2 e = 2 x 1.6 x 10^-19 C
Q = 82 e = 82 x 1.6 x 10^-19 C
Let d be the distance of closest approach
E = k Q q / d
Where, K = 9 x 10^9 Nm^2 / C^2
d = k Q q / E
d = (9 x 10^9 x 82 x 1.6 x 10^-19 x 2 x 1.6 x 10^-19) / (8.8 x 1.6 x 0^-13)
d = 2.7 x 10^-14 m
