8. If the mass of a balloon is 300 kg and the lift force provided by the atmosphere is 3300 N, what
zmey [24]

Answer:

Toward the north, 300 N

Explanation:

Consider the upward direction as positive and downward direction as negative.

Given:

Mass of the balloon is, m=300\ kg

Lift force on the balloon in the upward direction is, F_L=3300\ N

Take acceleration due to gravity as 10 N/kg.

Now, weight of the balloon acting downward is given as the product of its mass and acceleration due to gravity. Therefore,

Weight is, W=mg=(300\ kg)(10\ N/kg)=-3000\ N

Now, net force is given as the vector sum of both the forces.

F_{net}=F_L+W\\F_{net}=3300-3000=300\ N(\textrm{Upward direction})

The upward direction is the direction of North. So, the net force acting on the balloon is 300 N towards North.

At what distance above the surface of the earth is the acceleration due to the earth's gravity 0.855 m/s2 if the acceleration du
natulia [17]
Given: Normal pull of gravity g = 9.8 m/s²; 

 g = 0.855 m/s²  (at a certain distance)

Universal gravitational constant G = 6.67 x 10⁻¹¹ N.m²/Kg²

Mass of the Earth Me = 5.98 x 10²⁴ Kg

Radius r = ?

g = GMe/r²

r = √GMe/g

r = √(6.67 x 10⁻¹¹ N.m²/Kg²)(5.98 x 10²⁴ Kg)/(0.855 m/s²)

r = 2.16 x 10⁷ m or 

r =  21,610 Km

Explain the relationship among visible light, the electromagnetic spectrum, and sight.
yaroslaw [1]

Explanation:

The <em>electromagnetic spectrum</em> is the name given to the full range of frequencies and/or wavelengths that electromagnetic phenomena may have.

Human eyes respond to a small range of wavelengths in that spectrum. That response is called <em>sight</em>. Because humans can see that electromagnetic energy, it is called <em>visible light</em>.
