Traveling at high altitudes_________ vehicle engine performance when compared to operating the same vehicle at sea level

Physics
1 answer:
fredd [130]3 years ago
8 0

Answer:

Lessens

Explanation:

The performance of an engine at high altitudes is lower due to the decreasing density of air with elevation, such that at high altitude, the density is much less and a given quantity of oxygen occupies much more space at high altitudes, and the oxygen content in the air drawn in is lesser at high altitude, and the combustion power is much lesser at high altitudes when the engine speed is high up to about 4000 rpm.

An engineer weighs a sample of mercury (ρ = 13.6 × 103 kg/m3 ) and finds that the weight of the sample is 6.0 n. what is the sam
Amanda [17]
Given:
ρ = 13.6 x 10³ kg/m³, density of mercury
W = 6.0 N, weight of the mercury sample
g = 9.81 m/s², acceleration due to gravity.

Let V =  the volume of the sample.
Then
W = ρVg
or
V =  W/(ρg)
   = (6.0 N)/[(13.6 x 10³ kg/m³)*(9.81 m/s²)]
   = 4.4972 x 10⁻⁵ m³

Answer: The volume is 44.972 x 10⁻⁶ m³

How are passengers affected when a moving bus is stopped suddenly? Explain with reason.<br>​
Mademuasel [1]

Answer:

When a moving bus stops suddenly, the passenger are pushed forward because of the inertia of the passengers. ... Because the lower part of the body comes to rest with the bus while the upper part tends to continue its motion due to inertia.

Explanation :

The passengers in a bus tend to fall backward when it starts suddenly due to inertia as the passengers tend to remain in the state of rest while the bus starts to move. When the bus stops suddenly, people fall forward because their inertia as they are in state of motion even when the bus has come to rest.

Hope this helps!! <3
