just olya [345]

Answer:

Nuclear power plants are fueled by uranium, which emits radioactive substances. Most of these substances are trapped in uranium fuel pellets or in sealed metal fuel rods. However, small amounts of these radioactive substances (mostly gases) become mixed with the water that is used to cool the reactor.

A pilot wants to fly on a bearing of 74.9 degrees. By flying due east, he find s that a 42-mph wind, blowin from the south, puts
hichkok12 [17]
The bearing shows the angle from north to the line (c), you want to see the angle inside the triangle so that will be 90-[bearing]. 

<span>a=42 (42 mph wind blowing north) </span>

<span>A= 90-74.9 </span>
<span>A= 15.1 degrees </span>

<span>Ground speed is the speed the plane is going including the wind. </span>
<span>ground speed = c </span>
<span>Airspeed = b </span>

<span>You have the angle, and you have the "Opposite" and want to find the "Hypotenuse". </span>
<span>SOH CAH TOA </span>

<span>Sin x = Opp/Hypot </span>

<span>Sin(15.1) = 42/c </span>
<span>c = 42/Sin(15.1) </span>
<span>c = 161.53 </span>

<span>Ground speed of the plane is 161.53 mph </span>

<span>Airspeed = b </span>

<span>Tan x = Opp/Adj </span>
<span>Tan (15.1) = 42/b </span>
<span>b = 42/Tan(15.1) </span>
<span>b = 161.53 </span>

<span>Airspeed = 161.53 mph </span>

<span>(so the answer is ground speed of 161.53mph)</span>

A pulley 12 cm in diameter is free to rotate about a horizontal axle. A 220-g mass and a 470-g mass are tied to either end of a
Aleks [24]

Answer:0.147 N-m

Explanation:

Given

Diameter of Pulley d=12 cm

radius r=6 cm

mass of first object m_1=220 gm

mass of second object m_2=470 gm

Now both masses will exert a torque a on Pulley

Torque due to first Pulley T_1=m_1g\cdot r

T_1=0.22\times 9.8\times 0.06=0.129 N-m

Torque due to second mass on Pulley T_2=m_2g\cdot r

T_2=0.276 N-m

Total Torque by masses T_{net}=T_2-T_1

T_{net}=0.276-0.129=0.147 N-m

so we need to apply a torque of magnitude 0.147 N-m opposite to the direction of T_{net}
