Inertia ____.

1 answer:

4 0

The correct answer is (c.) resists a change in motion of an object. Inertia basically resists any physical changes in an object in terms of its state. As stated in the Newton's first law of motion or also known as law of inertia, an object that is at rest will stay at rest and an object that is in motion will stay in motion. In short, an object will keep doing what it is already doing UNLESS net force is acted upon it,

Under certain circumstances, potassium ions (K ) in a cell will move across the 8.15 nm thick cell membrane from the inside to t

Verdich [7]

Answer:

$1.288\times 10^{-20}\ J$

Increase

Explanation:

q = Charge in the potassium ion = $19e-18e$

e = Charge of electron = $1.6\times 10^{-19}\ C$

$V_2-V_1$ = Change in potential = $0-(-80.5\times 10^{-3})$

Change in electric potential is given by

$E=q(V_2-V_1)\\\Rightarrow E=(19e-18e)(0-(-80.5\times 10^{-3})\\\Rightarrow E=1.6\times 10^{-19}\times 80.5\times 10^{-3}\\\Rightarrow E=1.288\times 10^{-20}\ J$

The energy is $1.288\times 10^{-20}\ J$

The potential energy will increase.

Describe the role of observations in scientific endeavor and explain the characteristics of good observations.

koban [17]

Observations are used in order to collect data and record a variety of interesting or useful key points about the subject or specimen in observation. These observations, if made well, can be recorded and used to supplement a hypothesis.

How long does it take (in minutes) for light to reach mercury from the sun, a distance of 6.02 × 107 km?

Ksju [112]

Light travels at a speed of:
$c=3 \cdot 10^8 m/s$
The distance between Mercury and Sun is $S=6.02 \cdot 10^7 km=6.02 \cdot 10^{10} m$ , so the time it takes is
$t= \frac{S}{c}= \frac{6.02 \cdot 10^{10} m}{3 \cdot 10^8 m/s} =200.7 s$
if we want to convert this into minutes, keeping in mind that 1 min = 60 seconds, we should divide this value by 60:
$t= \frac{200.7 s}{60 s/min}=3.34 min$
