A cylinder of manganese (length 4.00 cm, diameter = 1.00 cm) has a mass of 22.62 g. What is the density of manganese?
Gnom [1K]
Equation for density is mass/volume

Mass=22.62 g

Volume= 22/7 x 1/2^2 x 4

3.14 x 0.5 x 0.5 x 4

=3.14 cm3

Mass/ Volume

22.62/3.14

7.2 g/cm3 is the answer

A company sells tents in two styles, shown below. The sides and floor of each tent are made of nylon. Which tent requires less n
BartSMP [9]

Answer:  Tunnel tent.

Step-by-step explanation:

The tent which has the minimum area requires less nylon to manufacture,

Since, the area of Pup tent = Area of 3 square each having side 8 ft + Area of 2 equilateral triangle having side 8 ft

= 3 \times ( 8^2 ) + 2\times \frac{64\sqrt{ 3} }{4}

=  192+ 2\times \frac{64\sqrt{ 3} }{4}

= 192+ 32\sqrt{ 3}

= 247.425625842\approx 247.43\text { square ft}

Now, the area of tunnel tent = Area of square having side 8 ft + total Area of half cylinder having radius 4 ft and height 8 ft

= 8^2 + \frac{1}{2} [ 2\pi\times 4(4+8)]

= 64 + \pi\times 48

= 64 + 3.14\times 48

= 214.72\text { square ft}

Since, 214.72 < 247.43

Thus, Tunnel tent requires less nylon to manufacture.

A plane, initially traveling 150 mi./hr. 100 east of north, suddenly enters a region where the wind is blowing at 50 mi./hr. fro
Leona [35]

Answer:

the Velocity of the plane is 100 mi/hr along the northeast direction

Step-by-step explanation:

According to the Question,

  • Given That, the Initial velocity of the plane is 150 mi/hr along the east north direction and the wind is blowing at 50 mi/hr along the southwest direction  

since the velocity of wind and plane is exactly opposite

  • the relative velocity of the plane with respect to the wind is given by

V_{r} = V_{p} -V_{w}  , where  V_{p} is the velocity of plane = 150mi/hr and V_{w} = velocity of wind = 50 mi/hr

  • Therefore,  Relative Velocity = 150-50 ⇒ 100mi/hr along northeast direction

Thus, the velocity of the plane is 100 mi/hr along the northeast direction
