Question

The limit of an indeterminate form does not exist
a)True
b)False

Answer 1

The correct answer is B.

Answer 2

The observed frequency at sound speed is not infinite, macroscopic objects do not exhibit wave-particle duality, gravity affects light despite its lack of rest mass, an acceleration graph is curved not straight, and the Necessary and Proper Clause often expands national government power.

Step-by-step explanation:

Let's address the provided true/false statements one by one:

1. Observed frequency and sound speed - False. When the source is moving at the speed of sound, the observed frequency does not become infinite. Instead, sound waves pile up and create a shock wave, such as a sonic boom, rather than an infinite frequency.
2. Wave-particle duality and macroscopic scale - False. Wave-particle duality is a concept that applies to quantum particles like electrons and photons. Objects on the macroscopic scale, such as cars or baseballs, do not exhibit wave-particle duality in any observable manner.
3. Light as a wave or particle and gravity - True. Although light has no rest mass, it is still affected by gravity due to its energy and momentum, according to General Relativity, which explains how gravity can bend a beam of light.
4. Position vs time graph for acceleration - False. The position versus time graph of an object that is speeding up is not a straight line; it is a curve. A straight line would indicate constant velocity, not acceleration.
5. Necessary and proper clause and national government power - False. The Necessary and Proper Clause has been interpreted to give the national government broad powers to perform duties not specifically enumerated in the Constitution, often expanding rather than limiting its power.
