Answer:
t = 1.58 s
Explanation:
given,
Speed of ranger, v = 56 km/h
v = 56 x 0.278 = 15.57 m/s
distance, d = 65 m
deceleration,a = 3 m/s²
reaction time = ?
using stopping distance formula
t is the reaction time
t = 1.58 s
hence, the reaction time of the ranger is equal to 1.58 s.
IF voltage remains constant, then current is
inversely proportional to resistance.
The correct response is "b).", signifying "false" as the choice.
Answer:
P V = N R T is the ideal gas equation
P2 / P1 = T2 / T1
The pressure will increase.
A. The switch within the closed circuit is opened.
If the switch is opened current will stop flowing, as the current will meet a gap, that is not connected by a conductor.
Answer:
a) 
b) 
Explanation:
The energy of the photon (E) for 
orbit of the hydrogen atom is given as:
where,
= 13.6 eV
n = orbit
a) Now for the transition from n = 4 to n = 5
b) Now for the transition from n = 5 to n = 6
