Two positively charged objects are located so they are 0.20 m apart. If the objects are separated until their centres are 0.40 m apart, by what factor will the electrostatic force between them change?

Answers

Answer 1

Answer: The electrostatic force is inversely proportional to the square of the distance that separates the center of the charges. Then if the distance is multiplied by 2, the force will be divided by a factor of 2^2 = 4 or multiplied by 1/4.

Explanation:

For safety concerning a curve, you shouldA. Decelerate before the curve
B. Accelerate before entering the curve
C. Applying the brakes only after exiting the curve
D. Apply the accelerator throughout the entire curve

Answers

Correct answer choice is:

A) Decelerate before the curve.

Explanation:

Decrease your speed before overtaking a curve. Watch out for road symbols signaling of nearing curves so that you have enough time to reduce down before driving through the curve. It is desirable to drive below the posted speed limit as you progress and drive through curves. Turn as little as probable.

For safety concerning a curve, the correct answer is:

A. Decelerate before the curve.

How to take caution on curves

When approaching a curve while driving, it is essential to slow down or decelerate before entering the curve. This allows you to maintain better control of the vehicle and reduce the risk of losing traction or skidding.

By reducing your speed before entering the curve, you can handle the curve more safely and smoothly, adjusting your steering and maintaining stability throughout the turn. Accelerating into a curve or applying the brakes only after exiting the curve can lead to unsafe driving conditions and increase the likelihood of accidents. It is always safer to slow down before taking a curve to ensure a safer driving experience.

Flatworms can be cut in half, creating two new individuals, by _____.binary fission
multiple fission
fragmentation
budding

Answers

Flatworms can be cut in halfcreating two individuals by binary fission. Binary fission is a type ofasexual reproduction in which the offspring has the same features andcharacteristics of the parent. During binary fission, the DNA replicates intotwo and goes at the end of each membrane. And then the cell membrane divides intotwo daughter cells. Then cytokinesis follow.

Answer:

If you think about you're cutting and Flatworm in half. Flatworms don't naturally divide/create new individuals by binary fission. So, the answer would be c) fragmentation; based on the fact that you are the one cutting the Flatworm, not the other way around.

What is the minimum coeffecient of static friction μmin required between the ladder and the ground so that the ladder does not slip?

Answers

Answer:

$\mu = (1)/(2tan\theta)$

Explanation:

let the ladder is of mass "m" and standing at an angle with the ground

So here by horizontal force balance we will have

$\mu N_1 = N_2$

by vertical force balance we have

$N_1 = mg$

now by torque balance about contact point on ground we will have

$mg((L)/(2)cos\theta) = N_2(L sin\theta)$

so we will have

$N_2 = (mg)/(2tan\theta)$

now from first equation we have

$\mu (mg) = (mg)/(2tan\theta)$

$\mu = (1)/(2tan\theta)$
