The latitude of any location on earth is the angle formed by the two rays drawn from the center of earth to the location and to

Alina [70]

The distance between city a and city b is 833.345 miles.

We know that

1°=60'

The distance of city a from the initial ray is calculated as

x_a=3960*tan45.46°=4024.101 miles

The distance of city b from the initial ray is calculated as

x_b=3960*tan 38.86°=3190.75 miles

Now the distance between city a and b is equal to

4024.101-3190.75=833.345 miles

This is the vertical distance between the cities.

The bodies in this universe attract one another name the scientist who propounded this statement

murzikaleks [220]

Answer:

It was proposed by Isaac Newton

Explanation:

The law of universal attraction of expression

F = $G \ \frac{m_1m_2}{ r^2}$ G m1m2 / r ^ 2

where G is a constant, m₁ and m₂ are the masses of the bodies and r the distance between them.

It was proposed by Isaac Newton

With this law Newton explained that the force that pulls the moon towards the earth is the same as that which attracts an apple towards the earth

How is the 3rd law different from the 1st and 2nd laws?

Semmy [17]

Answer:

In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.

A negative charge -0.550 HC exerts an upward 0.700 N force on an unknown charge 0.220 m directly below it. (a) What is the unkno

Sonja [21]

Answer:

Part a)

$q_2 = -6.8 \mu C$

Part b)

$F = 0.700 N$

direction = downwards

Explanation:

As we know that the negative charge will experience the force due to some other charge below it

the force is given as

$F = 0.700 N$

now we know that

$F = \frac{kq_1q_2}{r^2}$

now plug in all data

$0.700 = \frac{(9 \times 10^9)(0.550\mu C)q_2}{0.220^2}$

$0.700 = 1.022\times 10^5 q_2$

$q_2 = -6.8 \mu C$

since this is a repulsion force so it must be a negative charge

Part b)

As per Newton's III law it will exert equal and opposite force on it

So here the force on the charge below it will be same in magnitude but opposite in direction

so here we have

$F = 0.700 N$

direction = downwards

Explain why competitive athletes do not smoke give as many reasons as you can

Dvinal [7]

Answer:

Your muscles need oxygen to perform their function, and a reduction in the oxygen making its way to them means that muscles don't work as effectively. ... These negative effects are why most athletes don't smoke.
