A sports car and a fully loaded semi truck pull side by side at a red light. Using your knowledge of acceleration, predict which
Len [333]
According to Newtons second law of motion:

a =  \frac{F}{m}

This shows, acceleration and mass are inversely proportional. So, larger the mass, less will be the acceleration produced and vice versa.

In case of a sports car and a fully loaded truck, the mass of truck is a lot more than the sports car. As a result the sports car will accelerate faster when the traffic light turns green.

Which statement is true about the electrons in each polar bond of a water molecule?
Greeley [361]

They are more attracted by the oxygen atom than by the hydrogen atom.

Explanation:

In the polar bond of water which is made up of hydrogen and oxygen atoms, the shared electrons are more attracted by the oxygen atom than by the hydrogen atom.  

The interatomic bond in water is a polar covalent bond.  

In this bond type, two species shares their valence electrons.  

The bond usually occurs between non-metals with an electronegativity difference that is small.

Oxygen is more electronegative compared to hydrogen.

  • This implies that oxygen pulls the electron more closely to itself since it has a greater affinity.
  • This leaves a partial negative charge on oxygen and a positive charge on hydrogen.
  • The molecule is said to be polar covalent.

Why is it that the decomposition of nitroglycerin can result in so
patriot [66]

Answer:

with the molecular formula C3H5(ONO2)3, has a high nitrogen content (18.5 percent) and contains sufficient oxygen atoms to oxidize the carbon and hydrogen atoms while nitrogen is being liberated, so that it is one of the most powerful explosives known.

Explanation:

NTG reduces preload via venous dilation, and achieves modest afterload reduction via arterial dilation. These effects result in decreased myocardial oxygen demand. In addition, NTG induces coronary vasodilation, thereby increasing oxygen delivery.

A rotameter calibration curve (flow rate versus float position) obtained using a liquid is mistakenly used to measure a gas flow
Veronika [31]

Answer:

I would expect the gas rate determined in this manner to be too low

Explanation:

A Rotameter can be designed to respond to the sensitivity of density, velocity, to measure the flow rate of liquid or gas enclosed in a tube. Liquids are denser than gas, and since the gas rate to be determined needed to respond to the velocity head alone of the rotameter so as to bring the forces in the tube equilibrium. Knowing if there is no flow, then the float would remain at the bottom, so gas has to flow at a higher rate compared to the liquid so the float would be in a similar position making it easier to measure the flowrate. This leaves the gas rate to be determined too low.
