A 6.3 μC electric charge is placed in an Electric Field with a magnitude of 5.0 x 105 charge due to the Electric Field? N/C. What is the electric force on the charge due to the electric field

Answers

Answer:

F = 3.15 N

Explanation:

Given electric charge, q = 6.3 μC

The magnitude of electric field, [tex]E=5\times 10^5\ N/C[/tex]

We need to find the electric force on the charge due to the electric field. The electric force is given by :

F = qE

Putting all the values,

[tex]F=6.3\times 10^{-6}\times 5\times 10^5\\\\F=3.15\ N[/tex]

So, the required force on the charge is 3.15 N.

what are newtons laws of motion?

Answers

Answer:

In classical mechanics, Newton's laws of motion are three laws that describe the relationship between the motion of an object and the forces acting on it. The first law states that an object either remains at rest or continues to move at a constant velocity, unless it is acted upon by an external force.

Why the temperature of a resistor increase when a current pass through it

Answers

Answer:

So, when an electrical charge passes through a resistor, some of that electrical energy is transferred into heat, increasing the temperature. This extra energy causes the particles in the resistor to vibrate more. With these particles moving more, it is more difficult to for the electrons to move through the resistor.

"Influence" between bodies is reduced as the bodies are: brought closer moved farther apart increased in charge held stationary

Answers

Answer:

moved farther apart

Explanation:

Gravity is considered to be a universal force of attraction which acts between all objects that has both mass, energy and occupy space. Therefore, it acts in such a way as to bring objects together.

Additionally, the gravity of earth makes it possible for all physical objects to possess weight.

"Influence" between bodies is reduced as the bodies are moved farther apart based on Newton's law of universal gravitation.

Newton's law of universal gravitation states that the force of attraction (gravity) acting between the Earth and all physical objects is directly proportional to the Earth's mass, directly proportional to the physical object's mass and inversely proportional to the square of the distance separating the Earth's center and that physical object.

The density of an object determines whether it will float or sink in another substance. An object will float if it is less dense than the liquid it is placed in. An object will sink if it is more dense than the liquid it is placed in.
So since the boat has a lower density than the water, it will float.
So the answer is choice B

Ralston had lots of spicy and oily food which triggered heartburn. The doctor prescribed
him Milk of Magnesia.
a. Why did the doctor prescribe milk of magnesia?
b. What is the chemical name of milk of magnesia?

Answers

Answer:

A.) The doctor decided to prescribe milk of magnesia because of the mineral Magnesium. Magnesium helps to reduce stomach acid and increases the water in the intestines which helps induce motility in the intestines. Heartburn is caused by stomach acids traveling up into your esophagus which causes that feeling of your heart burning. Milk of magnesia will help soothe this.

B.) The chemical name of milk of magnesia is magnesium hydroxide.

Explanation:

The chemical name of the milk of magnesia is magnesium hydroxide.

An antacid is any substance that is taken to decrease or neutralize the acidity of the gastro intestinal tract. We must note that the gastrointestinal tract is natural acidic.

However, hyperacidity of the gastrointestinal tract could lead to heartburn. This acidity is neutralized using an antacid such as milk of magnesia. The chemical name of the milk of magnesia is magnesium hydroxide.

Identify what happens to the kinetic energy (KE) and gravitational potential energy (PE) of a rock as it falls.

KE and PE both increase.
KE and PE both decrease.
KE increases and PE decreases.
KE decreases and PE increases.

Answers

Answer:

KE increases and PE decreases.

Explanation:

POTENTIAL ENERGY (PE):

The potential energy of the rock depends upon the height of the rock, as given by the following formula:

P.E = mgh

Therefore, the potential energy will be highest at the initial point due to the highest height attained by rock. As the rock falls, its height will decrease as a result its potential energy will also decrease.

KINETIC ENERGY (KE):

The kinetic energy of the rock depends upon the velocity of the rock, as given by the following formula:

[tex]K.E = \frac{1}{2}mv^2[/tex]

Therefore, the kinetic energy will be zero at the initial point due to the zero velocity of the rock. As the rock falls, its velocity will increase as a result its kinetic energy will also increase.

Hence, the correct option will be:

KE increases and PE decreases.

Answer:

Explanation:

i )

area of small piston = 0.2 m²

Force = 100 N

pressure created on small piston

= 100 / .2 = 500 N/m²

According to Pascal's law , this pressure will be transmitted to larger cylinder .

area of larger cylinder = 5 m²

pressure = force / area

force in the large cylinder = pressure x area of large cylinder
