b. Mass.
c. Gravity.
d. Work.

Answers

Answer 1
Answer: B. Mass

It explains that,
"Matter and Energy are Interchangeable."
It's Einstein's equation meaning Energy is equal to the mass multiplied by the speed of light squared.

Technical advancements in transportation are very expensive and not available to everyone.

What is technical advancements in transportation?

A revolution is currently taking place in transportation technology. While new ideas are ready to completely transform how we move, new technologies are increasing the effectiveness of existing transportation techniques.

The newest transportation revolution has seen a growth in different technologies.

  1. The Internet of Things: The Internet of Things is predicated on the idea that all objects and people can be networked together. Route planning, accident prevention, and safety can be easily taken care by using internet.
  2. Autonomous Cars:  Autonomous vehicle technology is expected to advance and eventually replace human drivers as a safer option that also has additional economic and environmental advantages.
  3. Lightweight Vehicle Materials: Moving away from cast iron and steel is the main goal of research into lightweight materials. The most likely replacements for these metals in the near future are carbon fiber construction and magnesium-aluminum alloys.

Although these modern technologies are established to be environmental friendly, These advancements are very expensive and not available to everyone. This is one among the disadvantages of  technological advances in transportation.

Can someone plz tell me how to solve this step by step

Answers

Answer:

Explanation:

T=2π√l/g

to solve this for l we have to remove the square root in order to finish square root we have to take square on both side so the equation become

T²=4π²l/g

multiplying g on both side

T²g=4π²l

now dividing 4π² on both side

T²g/4π²=l

so l=T²g/4π²

Resistivity measurements on the leaves of corn plants are a good way to assess stress and overall health. The leaf of a corn plant has a resistance of 2.3 MΩ measured between two electrodes placed 20 cm apart along the leaf. The leaf has a width of 2.3 cm and is 0.20 mm thick.Part AWhat is the resistivity of the leaf tissue?Express your answer to two significant figures and include the appropriate units.ρ=________Part BIs this greater than or less than the resistivity of muscle tissue in the human body?(A) greater or(B) less

Answers

Answer:

Part a)

\rho = 52.9 ohm- m

Part b)

the resistivity of corn plant is grater than the resistivity of muscle tissue in the human

Explanation:

Part a)

As we know the formula of resistance is given as

R = \rho (L)/(A)

here we know that

\rho = (RA)/(L)

here we have

R = 2.3 M ohm

L = 20 cm

Area = (0.023)(0.20 * 10^(-3))

Area = 4.6 * 10^(-6) m^2

now we have

\rho = ((2.3 * 10^6)(4.6 * 10^(-6)))/(0.20)

\rho = 52.9 ohm- m

Part b)

Resistivity of mucle tissue of human is is ranging from 15 ohm-m to 50 ohm m so here we can say that

the resistivity of corn plant is grater than the resistivity of muscle tissue in the human

What is the value of x in the equation below 1+2e^x+1=9

Answers

Answer: 1.252

Explanation:

We are given this equation and we need to find the value of x:

1+2e^x+1=9   (1)

Firstly, we have to clear x:

2e^x=9-1-1  

2e^x=7  

e^x=(7)/(2)     (2)

Applying Natural Logarithm on both sides of the equation (2):

ln(e^x)=ln((7)/(2))     (3)

xln(e)=ln((7)/(2))     (4)

According to the Natural Logarithm rulesxln(e)=x, so (4) can be written as:

x=ln((7)/(2))     (5)

Finally:

x=1.252
