Answer:
Incomplete question: "Each block has a mass of 0.2 kg"
The velocity of the center of mass for the two-block system just prior to their collision is 2.9489 m/s
Explanation:
Provided information:
θ = angle of the surface = 37°
m = mass of each block = 0.2 kg
v = speed = 0.35 m/s
t = collision time = 0.5 s
Question: What is the velocity of the center of mass for the two-block system right before the blocks collide, vf =?
Change in momentum:
It’s essential to calculate the required force:
Here, g = acceleration due to gravity = 9.8 m/s²
Answer:
D, C, B, A
Explanation:
The derivative from a velocity-time graph provides the acceleration value.
Segment A
Segment B
Segment C
Segment D
Sorted from the lowest to the highest acceleration:
D, C, B, A
Answer:
Amplitude, A = 0.049 meters
Explanation:
Given that
A harmonic wave propagates in the positive x direction at 6 m/s along a tight string. A fixed point along this string oscillates over time according to the equation:
.......(1)
The general wave equation is expressed as:
.......(2)
A denotes the wave's amplitude
When we compare equation (1) with (2), we find:
A = 0.049 meters
Thus, the amplitude of the wave is 0.049 meters.
Could a friend confirm this answer? I'm not completely certain, but I believe that visible light is required to generate the photoelectric effect.
