Explanation:

<u><em /></u>

<u><em>[Question] : </em></u>

<em>Why is riding a bike better for the environment than driving a car?</em>

<u><em /></u>

<u><em>Answer choices Explanation:</em></u>

<em>[A] Bikes do not require gasoline.</em>

<em>That True as well as it doesn't require gasoline which protect the environment</em>

<em />

<em>[B] That also True but it doesn't explain why riding a bike is better for environment</em>

<em />

<em>[C] Bikes require more energy to move.</em>

<em>That True for humans we have to ride it but that doesn't given a reason on why riding a bike is better for environment</em>

<em />

<em>[D] Bikes require the building of more roads.</em>

<em>Why having a bikes require building of more roads?? Maybe car need more roads but I don't see a point to make more roads for bikes.</em>

<em />

<em>Hence, [A] Bikes do not require gasoline Given the best answer for riding a bike better for the environment than driving a car</em>

Which sample of oxygen gas contains molecules with the fastest average speed?
mote1985 [20]

Answer:

A. 1.73 x 10^5 J

Explanation:

The internal energy of a gas is related to the average speed of the molecules of the gas. In fact:

- The internal energy, U, is directly proportional to the temperature of the gas, T, according to

U=\frac{3}{2}nRT

- The temperature of the gas, T, is proportional to the square of the average speed of the molecules, v, according to

\frac{3}{2}kT=\frac{1}{2}mv^2

where both terms represent the average kinetic energy of the molecules.

- Therefore, we can conclude that the higher the internal energy, the faster the average speed of the molecules: among the choices given, the sample with highest internal energy is sample A.

shirley knott, a 65kg astronaut holds a 12kg tank of oxygen, which she throws backwards at 2.2m/s. with what speed does she move
babymother [125]

This question involves the concepts of the law of conservation of momentum and speed.

She moves with a speed of "0.41 m/s".

Applying the law of conservation of momentum to this situation, we get:

m_1u_1+m_2u_2=m_1v_1+m_2v_2

where,

m₁ = mass of shirley = 65 kg

m₂ = mass of tank = 12 kg

u₁ = initial speed of shirley = 0 m/s

u₂ = initial speed of tank = 0 m/s

v₁ = final speed of shirley = ?

v₂ = final speed of tank = 2.2 m/s

Therefore,

(65\ kg)(0\ m/s)+(12\ kg)(0\ m/s)=(65\ kg)(v_1)+(12\ kg)(2.2\ m/s)\\\\v_1=\frac{-26.4\ kg.m/s}{65\ kg}\\\\v_1=-0.41\ m/s

negative sign shows the opposite direction.

The persistence of vision for normal eye is
attashe74 [19]

Answer:

The answer is 1/16

Explanation:

1. Persistence of vision refers to the optical illusion that occurs when visual perception of an object does not cease for some time after the rays of light proceeding from it have ceased to enter the eye. 2. The persistence of vision for normal eye is 1/16 if a second.
