A town is considering building a biodiesel power plant that would burn biomass to generate electricity. Which of the following c

orrectly lists an advantage and a disadvantage of this project?
A) Advantage: it could help get rid of unwanted waste. Disadvantage: there is no way to use the electricity created.
B) Advantage: it reduces dependence on fossil fuels. Disadvantage: it would emit pollution into the air.

C) Advantage: it is a commonly used energy source. Disadvantage: building the plant would attract new people to the area.

D) Advantage: it would use energy from the sun and wind. Disadvantage: it is a non-renewable source of energy.

What is Force?

In the field of physics, an influence that can alter the motion of an object is referred to as a force. An object having mass can experience a change in its velocity, often known as an acceleration, when subjected to a force. Intuitively, force can also be conceptualized as either a push or a pull. Because it may be measured in both magnitude and direction, a force is considered a vector quantity.

What is atmospheric pressure?

The pressure that is exerted within the atmosphere of the Earth is referred to as barometric pressure as well as atmospheric pressure. As a unit of pressure, the standard atmosphere is defined as having a value of 101,325 Pa. This value is equivalent to 1013.25 millibars, 760 mm Hg, 29.9212 inches Hg, or 14.696 psi.

In most situations, the equation for force can be expressed numerically as

Force = pressure * A

Therefore

F= (970 - 15 B)(\pi * (0.430 )^2)

F= 53731 N

In conclusion, If each horse can pull with a force of 1450N

The number of horses required is

N=\frac{60754 }{1450}

N=37.05

A chain reaction results when a uranium atom is struck by a/an ______________released by a nearby Uranium atom undergoing fissio
finlep [7]

Answer:

Chain reaction is possible by neutron

Explanation:

Nuclear reaction is mainly two types,

⇒ Nuclear Fission : heavy atom split into two light atom.

Ex. Uranium, thorium

⇒ Nuclear fusion : lighter atom combine together

Ex. Hydrogen to helium

In fusion reaction the large amount of energy is produced as compare to fission reaction.

Sun gets brighter by fusion reaction.

In case of uranium fission reaction is possible by colliding neutron.

One end of a piano wire is wrapped around a cylindrical tuning peg and the other end is fixed in place. The tuning peg is turned
liq [111]

Answer:

T = 3183 N

Explanation:

When the screw is turned by two turns then change in the length of the wire is given as

\Delta L = 2(2\pi r)

\Delta L = 4\pi r

\Delta L = 4(\pi)(1.0 mm)

\Delta L = 12.56 mm

now we know by the formula of Young's modulus

Y = \frac{T/A}{\Delta L/L}

so we have

T = \frac{AY \Delta L}{L}

T = \frac{\pi (0.55 \times 10^{-3})^2(2.0 \times 10^{11})(12.56 \times 10^{-3})}{0.75}

T = 3183 N
