Answer:
ac = 2.86 m / s²
Explanation:
Image can detail the system to determine the force in the FA to understand the system into the applicated force
m = 100 kg , L = 3 m
∑ F = 0 ⇒ Ay - 100 kg + P * cos (45) = 0
Ay = 768.86 N
∑ Mₐ = α * I ₐ
I ₐ = m * L² / 3 ⇒ I ₐ = 100 kg * 4² m / 3
Replacing
P * sin (45) * 3 = α * 100 kg * 4² m / 3
α = 1.193 rad / s²
ac = α *2 ⇒ ac = 1.193 rad / s² * 2
ac = 2.86 m / s²
That speed is (1m / 0.003sec) = 333 and 1/3 meters per sec .
The medium is not necessarily, but <u>could</u> be, air at sea-level pressure.
Answer:
C
Explanation:
vectors are any quantities that have both magnitude and direction
therefore both inertia and weight are both vectors
It took the train a total of 4 days to travel that long
Answer:
(A) 654.545 Kw
(B)
Explanation:
We have given resistance of the toaster
Resistance of nichrome heating element
Both the resistances are connected in series so same current will flow through the circuit
Potential difference across the toaster V = 120 volt
So current
(a) Power dissipated in toaster
(B) Power dissipated in heating element
