Answer:

1.152 miles

Explanation:

Given: central angle = 1 minute = (\frac{1}{60}) ^{o}

           radius of the earth = 3960 miles

The length of an arc = \frac{\alpha }{360^{o} } 2\pir

where: \alpha is the central angle, and r is the radius.

Thus,

Distance along the arc = \frac{\alpha }{360^{o} } 2\pir

Distance along the arc = \frac{(\frac{1}{60}) ^{o}  }{360^{o} } x 2 x \frac{22}{7} x 3960

                                      = \frac{(\frac{1}{60}) ^{o}  }{360^{o} } x 24891.4286

                                      = 1.1524

The required distance along an arc is 1.152 miles.

An object has a kinetic energy of 275 j and a momentum of magnitude 25.0 kg · m/s. find the (a) speed and (b) mass of the object
Sergeu [11.5K]
Kinetic energy = momentum^2 / 2 x mass
Mass = (momentum^2/ Kinetic energy) / 2

Mass =  (25^2 / 275) / 2
Mass = 1.136 kg.

momentum = mass x velocity

velocity = mass / momentum
velocity = 1.136 / 25
velocity = 0.04544 m/s

<u>Answer</u>

D. Base units

<u>Explanation</u>

Basic units are also called fundamental units. They are the standard units agreed internationally for measurements. Most of these measurements are taken from the ground and they are used to derive other units. They are seven in number. There are:

The metre (m)

The kilogram (kg)

The second (s)

The ampere (A)

The kelvin (K)

The candela (cd)

The mole (mol)

An atom of sodium-23 (atomic number = 11) has a positive charge of +1. Given this information, how many
12345 [234]
It has a 10 electrons. Since it's atomic number is 11 it must have 11 protons. Also, given that it has a +1 charge, it has one less electron than protons since they have equal but opposite charges. The number of protons is the mass number minus the atomic number = 23-11= 12 neutrons.

I think this is AWESOME, but I think the last sentence of your conclusion is a bit off. <span> "If someone has an allergy to oil then they can still eat cake because applesauce makes an amazing substitute for oil." I think that you should say "This recipe is great for those who cannot eat/drink oil, the applesauce is an amazing substitute for oil."

I hope I helped! -Wajiha</span>
