D. Advances in technology were needed to gather more evidence.

Explanation:

New technologies had to be developed to ascertain Wegener's claims.

The major flaw in Wegener's postulate was that the moving continents lacked a mechanism to drive them into motion.

His theory needed more scientific backing also.

  • A major leap was made when new technologies used during the second world war was deployed to investigate the ocean floor.
  • Sequences of magnetic anomalies were unraveled using equipment developed during the second world war
  • This gave further proof to the idea of continental drift and it expanded the theory into a more broader and inclusive theory of plate tectonics.

In the absence of air resistance, a ball of mass m is tossed upward to reach a height of 20 m. at the 10 m position, halfway up,
Mazyrski [523]

On the ball, there is mg of net force.

<h3>How would one describe air resistance?</h3>
  • Air exerts a force known as air resistance. The force works in the opposite direction of an object traveling through the air.
  • While a sports vehicle with a streamlined design will encounter reduced air resistance and experience less drag, the automobile will be able to move more quickly than a truck with a flat front.
<h3>What Causes Air Resistance?</h3>
  • Air resistance, also referred to as "drag," is a force brought on by air. When air specks collide with an object's front, it slows down.
  • The more air particles that impact the object and the larger its surface area, the more resistance it faces.

Hey guys how to prevent from shock
Pie
U need an insulator to prevent the shock passing through , that's why there is a plastic sheet covering the copper wires so that it can prevent the electricity passing through as plastic is an insulator and does not conduct electricity

The potential difference between A and B is 5.0 V. A proton starts from rest at A. When it reaches B what is its kinetic energy?
Aleksandr [31]

Answer:

total kinetic energy is 8 × 10^{-19} J

Explanation:

given data

potential difference = 5 V

e = 1.60 × 10^{-19} C

to find out

what is kinetic energy

solution

we will apply here conservation of energy that is

change in potential energy is equal to change in kinetic energy

so

change potential energy is e × potential difference

change potential energy =  1.60 × 10^{-19} × 5

change potential energy = 8 × 10^{-19} J

so change in kinetic energy  = 8 × 10^{-19} J

and we know proton start from rest that mean ( kinetic energy is 0 ) so

change in KE is total KE

total kinetic energy is 8 × 10^{-19} J
