oo.p i wish I could answer that
Explanation:
Answer:
a) T=1.35s
b) amplitude = 0.0923m
Explanation:
m=300 gr
k=6.5 N/m
first we need to get the angular frequency of the motion
so we have that
ω = √(k/m)
in this case motion is a simple harmonic so the period is defined by:
T= 2π / ω
T= 2π / √(k/m)
replacing the variables...
T= 2π / √(6.5/0.3)
T=1.35s (period of the block's motion)
and...
α max = | ω²r max |
2 = (2π/1.35)² * r max
r max= 0.0923m
Answer:
14 N
Explanation:
The tension in the second string is puling both the masses of 20 kg and 8 kg with acceleration of 0.5 m s⁻²
So tension in the second string = total mass x acceleration
= 28 x .5 = 14 N . Ans..
Answer:
RT = 35 Ohms
Explanation:
Let the three resistors be R1, R2 and R3 respectively.
Given the following data;
R1 = 14 Ohms
R2 = 12 Ohms
R3 = 9 Ohms
To find the total resistance, RT;
Since all the resistors are connected in series, the total resistance is equal to the sum of all three resistance of the resistors.
RT = R1 + R2 + R3
Substituting into the equation, we have
RT = 14 + 12 + 9
RT = 35 Ohms.
Therefore, the total resistance of the circuit is 35 Ohms.
