The right answer for the question that is being asked and shown above is that: "A.tectonic activity concentrated in certain areas." A piece of evidence did Alfred Wegener use to develop the theory of continental drift is that A.tectonic activity concentrated in certain areas

A charge of +1.4 × 10Ò coulombs moves from point A to B. What is the potential difference between the two points if the work done on the charge is +3.4 × 10¥ joules?

Answers

The exponents in both data quantities needed to calculate the answer have been corrupted and misprinted, so no answer is possible. Proofreading was REALLY needed for this one, but alas . . .

The conductive tissues of the upper leg can be modeled as a 40- cm-long, 12-cm-diameter cylinder of muscle and fat. The resistivities of muscle and fat are 13 Ω m and 25 Ω m, respectively. One person’s upper leg is 82% muscle, 18% fat. What current is measured if a 1.5 V potential difference is applied between the person’s hip and knee?

Answers

Answer:

current = 0.0027 A

Explanation:

the resistivity of upper leg

$\rho = 0.82 (13) + 0.18(25) = 15.16 ohm . m$

Resistance of upper leg

$R = (\rho L)/(A)$

$= (\rho L)/(\pi R^2)$

$= (15.16 * 0.40)/(\pi [(0.12)/(2)]^2)$

= 551.27 ohm

current $i = (V)/(R)$

$current = (1.5)/(551.27)$

current = 0.0027 A

An object traveling in a straight line accelerates. What will definitely happen due to the acceleration?

Answers

"Acceleration" means any change in speed or direction of motion.
If the object is known to be accelerating even though it's traveling
in a straight line, then we know that its speed must be changing.

Where will water evaporate from?A. from oceans and rivers only
B. from rivers and streams only
C. from any water source and life forms
D. from life forms only

Answers

Water will evaporate from any water source and life forms. The answer is letter C. An application of heat into water will cause the water to evaporate. This is because the intermolecular forces of attraction of water can be broken by sufficient energy application.
