To solve this problem you must apply the proccedure shown below:
 1. You must apply the following formula:
 yo=-(Voy)t+gt²/2
 2. You have that:
 Voy=VoxSin(30°)
 Voy=(12 m/s)(Sin(30°))
 Voy=6 m/s
 t=5.6 s
 g=9.8 m/s²
 2. When you susbtitute these values into the formula, you obtain:
 yo=-(6 m/s)(5.6 s)+(9.8 m/s^2)(5.6 s)²/2
 yo=120.06 m
 Therefore, the answer is: 120.06 m

11) Specific resistance is also called ? and is abbreviated with the capital letter K or the Greek letter ρ (rho).
Nuetrik [128]

Answer:

Resistivity

Step-by-step explanation:

Resistivity : It is a fundamental property of a material that measures how strongly a particular material opposes the flow of electric current. It is also known as specific resistance.

  • A low resistivity indicates a material that easily allows the flow of electric current.
  • Resistivity is commonly represented by the Greek letter ρ (rho) or abbreviated with a a capital letter K. The SI unit of electrical resistivity is the ohm-metre (Ω⋅m).

Hence, the correct answer for the blank is Resistivity.

What is the volume of this figure? <br> need help asap!!!!!
Marina CMI [18]

Answer: the answer should be 875 cubic feet

Step-by-step explanation:

The why is because we have to divide each rectangular prism into different pieces to use the volume formula. Doing this gives us 5*15*5 for the first part, the second part will be 20*5*5, the third square is 5*5*5.
