Answer:

A positive charge placed in an electric field will tend to move in the direction of the electric field lines and a negative charge will tend to move opposite to the direction of the electric field lines.

One way to remember this is that there is one velocity, and so the thumb represents it. There are many field lines, and so the fingers represent them. The force is in the direction you would push with your palm. The force on a negative charge is in exactly the opposite direction to that on a positive charge.

Two spherical point charges each carrying a charge of 40 μC are attached to the two ends of a spring of length 20 cm. If its spr

PolarNik [594]

Answer:

$x=3$

Explanation:

From the question we are told that:

Charge $Q=40 \mu C$

Length $L=20cm=0.20m$

Spring constant $k=120Nm^{-1}$

Generally the equation for Force between Charges is mathematically given by

$F=k\frac{q_1 q_2}{r^2}$

$F=9*10^9\frac{40*10^{-6}^2}{0.2^2^2}$

$F=360N$

Therefore

$F=kx$

$x=\frac{F}{k}$

$x=\frac{360}{120}$

$x=3$

What maximum upward acceleration can it give the elevator without breaking?.

MariettaO [177]

The maximum upward acceleration that the elevator can have without breaking is = 10.36m/s².

<h3>How to calculate maximum upward acceleration?</h3>

To calculate the maximum acceleration of the elevator we must take into account Newton's second law and its formula that takes into account the following aspects:

F = Is the force applied in newtons.
m = Is the mass of the object in kilograms.
a = Is the acceleration of the object in meters per second squeared.

F = m × a

According to the above, we apply the values we have as follows:

a = $\frac{F}{m}$

a = $\frac{21750N}{2100Kg}$

a = 10.36 m/s²

Note: This question is incomplete because some information is missing. Here is the complete information.

How does solubility change with temperature changes?

matrenka [14]

Answer:

Solubility increases with temperature.

Explanation:

-Increasing temperatures, increases the kinetic energy that allows solvent molecules to more effectively break apart the solute molecules.

-This solute molecules are held together by intermolecular attractions which weakens in higher temperatures.

-Solubility therefore increases with increasing temperatures.

Evaluating alternative options and choosing one option among them is called the theory of bounded rationality.

VikaD [51]

It is false, bounded rationality is the idea that rationality is limited when individuals make decisions. ... Limitations include the difficulty of the problem requiring a decision, the cognitive capability of the mind, and the time available to make the decision.

But one thing, NEXT TIME TELL US THE QUESTION FIRST AND DON'T JUST LEAVE BLINDLY ASKING SOMETHING.

Assume: The bullet penetrates into the block and stops due to its friction with the block. The compound system of the block plus

charle [14.2K]

Answer:

The total energy of the composite system is 7.8 J.

Explanation:

Given that,

Height = 0.15 m

Radius of circular arc = 0.27 m

Suppose, the entire track is friction less. a bullet with a m₁ = 30 g mass is fired horizontally into a block of wood with m₂ = 5.29 kg mass. the acceleration of gravity is 9.8 m/s.

Calculate the total energy of the composite system at any time after the collision.

We need to calculate the total energy of the composite system
