What is the momentum of a bus that weighs 13,500,000 grams traveling at 65 mph?

Physics

Goryan [66]3 years ago
5 0

The momentum of the bus is 3.93\cdot 10^5 kg m/s

Explanation:

The momentum of an object is given by

p=mv

where

m is the mass of the object

v is its velocity

For the bus in this problem, we have

m=13,500,000 g = 13,500 kg is its mass

v=65 mph \cdot \frac{1609 m/mi}{3600 s/h}=29.1 m/s is the velocity, converted into SI units

Substituting into the equation, we find the momentum of the bus:

p=(13,500)(29.1)=3.93\cdot 10^5 kg m/s

Reika [66]

Answer:

A. It sought to justify the divine right of kings

Explanation:

The Age of Enlightenment or the Enlightenment period was a period of the intellectual and the philosophical movement which dominated in Europe in the world of ideas during 17th and the 18th centuries.

The Enlightenment philosophers of that time greatly influenced the founders of the American government as they provided a government with consent, the idea of the natural rights of its people,etc.

The Protestant theory of the social contract conflicted with divide rights of the kings which was a catholic idea.

Thus option (A) is correct.

A wheel of diameter 8.0 cm has a cord of length 6.0 m wound around its periphery. Starting from rest, the wheel is given a const
MAVERICK [17]

Answer: time t = 10s

Explanation:

Given;

Diameter = 8.0cm = 0.08m

Radius r = diameter/2 = 0.08/2 = 0.04m

Cord length d = 6.0m

Angular acceleration = 3.0rads/s2

Time = t

Converting the angular acceleration to linear acceleration

a = a* × r = 3.0 × 0.04 = 0.12m/s

d = vt + 1/2 (a × t^2)

Initial velocity v = 0, vt = 0 therefore;

d = 1/2 ( a × t^2)

t = √(2d/a)

t = √ [(2× 6)/0.12]

t = 10s

Which image represents the force on a positively charged particle caused by an approaching magnet?
Amanda [17]

Answer:

Image B represents the force on a positively charged particle caused by an approaching magnet.

Explanation:

The most fundamental law of magnetism is that like shafts repulse each other and dissimilar to posts pull in one another; this can without much of a stretch be seen by endeavoring to put like posts of two magnets together. Further attractive impacts additionally exist. On the off chance that a bar magnet is cut into two pieces, the pieces become singular magnets with inverse shafts. Also, pounding, warming or winding of the magnets can demagnetize them, on the grounds that such dealing with separates the direct game plan of the particles. A last law of magnetism alludes to maintenance; a long bar magnet will hold its magnetism longer than a short bar magnet. The domain theory of magnetism expresses that every single enormous magnet involve littler attractive districts, or domains. The attractive character of domains originates from the nearness of significantly littler units, called dipoles. Iotas are masterminded in such a manner in many materials that the attractive direction of one electron counteracts the direction of another; in any case, ferromagnetic substances, for example, iron are unique. The nuclear cosmetics of these substances is with the end goal that littler gatherings of particles unite as one into zones called domains; in these, all the electrons have the equivalent attractive direction.

Why does Quito, Equator has very little changes to the daylight hours<br> throughout the year?
marin [14]

Because of the position on the equator, the change in rotation of the Earth on its axis throughout the year doesn't affect it much. Unlike the poles, Quito is almost constantly in direct view of the sun. So, because of lack of change in rotation, the daylight hours are hardly varied as Quito is almost constantly in more or less the same spot in relation to the sun.
