Answer:vapour gets stuckes into the carburetor when the car engine heat up with continuous acceleration and deceleration.
Explanation:Vapor lock occurs when the car engine gets heat up with continuous acceleration and deceleration. The automobile engine has to work harder during the hot summer days. An automobile engine runs hotter than usual in the stop-go traffic.. This extreme heat vaporizes the fuel in carburetor and fuel pump.
Answer:
E.) Circuit Breaker is the correct answer.
Explanation:
Circuit Breaker is an automated electrical device that is designed to control and stop the excessive current flowing if the crosses a particular level and it protects the electrical circuit from the damage that can be caused due to overload of current that is the reason Circuit Breaker is called protective device.
There are different types of circuit breakers such as oil circuit breaker, vacuum circuit breaker, outdoor circuit breaker, Spring operated circuit breaker, Hydraulic circuit breaker and Medium-voltage circuit breaker, etc.
Answer:
D: Scientists have not been successful in disproving the atomic theory.
Explanation:
This theory has had great implications in the understanding of nature at the microscopic level, from the first atomic model to the quantum model of the atom. All modern physics, chemistry and biochemistry are based on the theory that matter is composed of atoms of different elements. It has not been possible to disprove this theory or replace it with a better one.
Answer:
Because the light reflects multiple times until it gets to the Cassegrain focus.
Explanation:
The Cassegrain design can be seen in a reflecting telescope. In this type of design the light is collected by a concave mirror, and then intercepted by a secondary convex mirror, and sends it down to a central opening in the primary mirror (concave mirror), in which a detector is placed (Cassegrain focus)
Since, the light is reflected many times due to Cassegrain design, that leads to shorter telescopes.
So, all Turkeys work to attract female Turkeys, but only dominant Turkeys benefit from it, and the less dominant Turkeys don't benefit at all from it. That means that they are exhibiting altruism:selfless behavior.
However, in practical terms their behaviour also helps them, as they are often related to the dominant males.
