Answer:
400 Ns
Explanation:
Impulse = Change in momentum
i.e I = ΔP
So that,
Impulse experienced by Max = Change in Max's momentum
Change in Max's momentum = m(v - u)
Where m is the mass, v is the velocity after collision, and u is the velocity before collision.
m = 100.0 kg, v = 2.0 m/s, u = 6.0 m/s
Change in Max's momentum = 100 x (2 -6)
= -400 kg m/s
The negative sign shows that the change in momentum was against his direction of motion.
Impulse experienced by Max = 400 Ns.
Thus,
Max experienced an impulse of 400 Ns as a result of the collision.
Answer:
Q=1.42 C
Explanation:
Given that
When t= 0 ,Io = 3 A
τ = Time constant = 0.5 s
We know that
Q=Charge ,I =Current
Q = ∫I.dt
Given that
t= 0 to t= 3τ= 1.5 s
The charge Q
Q=1.42 C
Therefore charge flow conductor will be 1.42 C.
Answer:
It is perceived as louder.
Explanation:
Amplitude affects the loudness of sound.
Frequency and wavelength affect the pitch of the sound.
Air spaces are used in insulation because air is a poor conductor.
