Answer:
Q1: No
Q2: No
Explanation:
the slope of velocity time graph gives the value of acceleration.
In section B
the graph is parallel to X axis, it means it is moving with constant velocity. Here the slope of graph in section B is zero.
Q1: Object is moving with constant velocity
Q2: The acceleration is zero

A rock at rest has weight 138 n. what is the weight of the rock when it is accelerating downward at 3.5 m/s2?
The weight of the rock when it is accelerating downward at 3.5 m/s² can be calculated using the formula Weight = Mass * Acceleration due to gravity.
Explanation:The weight of an object is equal to its mass multiplied by the acceleration due to gravity. In this case, the weight of the rock when it is at rest is 138 N. Since the rock is accelerating downward at 3.5 m/s², the weight can be calculated using the formula:
Weight = Mass × Acceleration due to gravity
Let's assume the mass of the rock is 'm'. The acceleration due to gravity is approximately 9.8 m/s² on Earth. So, when the rock is accelerating downward at 3.5 m/s², its weight can be calculated as:
Weight = m × 3.5 m/s²
What is the wavelength of radiation with a frequency of 1.50x10^13 hz?
We have that for the Question "What is the wavelength of radiation with a frequency of 1.50x10^13 hz? " it can be said that the wavelength of radiation with a frequency of 1.50x10^13 hz
[tex]\lambda=2*10^{-5}m[/tex]
From the question we are told
What is the wavelength of radiation with a frequency of 1.50x10^13 hz?
Generally the equation for the wavelength is mathematically given as
[tex]\lambda=\frac{V}{f}\\\\\lambda=\frac{3*10^8}{1.50x10^{13} }\\\\\lambda=2*10^{-5}[/tex]
Therefore
the wavelength of radiation with a frequency of 1.50x10^13 hz
[tex]\lambda=2*10^{-5}m[/tex]
