Mrs. Patil travels from her home to work in 0.25 hours. The direct distance between her home and work is 8.0 miles. If Mrs. Patil travels 12.4 miles from home to her job, what is her average velocity during the trip?

Answers

Regardless of the path taken, at the end of the trip Mrs. Patil will be 8.0 miles away from home. If the path taken involves a trip lasts 0.25 hours, then the average velocity over the trip is

$\frac{8.0\,\mathrm{mi}}{0.25\,\mathrm h}=32\,\frac{\mathrm{mi}}{\mathrm h}$

Mass and weight are similar but not the same thing. In which of the following examples would the objects weight change, but made stay the same? An astronaut travels from the earth to the moon

A child grows taller

An overweight person goes on a diet

A snowball rolls downhill and picks up snow making it grow

Answers

we know that , weight of an object is given as

W = mg

where W = weight , m = mass of the object and g = acceleration due to gravity at that place.

An astronaut travels from the earth to the moon :

as the astronaut travels from the earth to the moon, the mass of astronaut stays the same but the weight change as acceleration due to gravity change since acceleration due to gravity on moon is only 1/6 times that on earth.

A child grows taller :

as child grows taller , he gains body mass . hence both mass and weight change.

An overweight person goes on a diet :

as an overweight person goes on diet , he loose body mass . hence both mass and weight change.

A snowball rolls downhill and picks up snow making it grow :

As snowball rolls downhill , it gains snow, hence its mass and in turn the weight change.

The force against a solid object moving through a gas or a liquid

Answers

This drag force is always opposite to the object's motion, and unlike friction between solid surfaces, the drag force increases as the object moves faster.

How does the sun cause wind?

Answers

wind is caused by a difference in pressure from one area to another area on the surface of the earth. Air naturally moves from high to low pressure, and when it does, it is called wind. Generally, we can say that the cause of wind is the uneven heating of the earth's surface by the sun.
