A hydraulic press consist of of two
cylinders of cross sectional areas
0.2m2 and 5m². The piston in the
smaller cylinder is pushed down
with a force of 100N through a
distance 0.2m. calculate
Links
(0)
The pressure transmitted
(ii)
The force exerted by the
piston in the larger cylinder.
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
ii )
pressure = force / area
force in the large cylinder = pressure x area of large cylinder
= 500 x 5
= 2500 N .
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?
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.
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.

This graph shows a supply curve. A graph titled Supply Curve has Quantity Supplied on the x-axis, from 0 to 50 in increments of 10, and price on the y-axis, from 0 to 15 dollars in increments of 5 dollars. A line is drawn with points (10, 5 dollars), (20, 7 dollars), (30, 10 dollars), (40, 13 dollars), and (40, 15 dollars). What happens when the price of a good increases? The quantity of goods that are produced increases. The producer of the good is certain to make less money. The quantity of goods that are produced decreases. The quantity of goods that are produced stays about the same.
Answer:
A just took the quiz on edge
Explanation:
In the supply curve, when the price of a good increases, A. The quantity of goods that are produced increases.
What is supply?Supply simply means the quantity of goods and services that a supplier is willing to sell at a particular place, price and time.
In this case, when there's an increase in the price of goods, it should be noted that producers will supply more of the goods. This is done in order to generate more revenue.

"Influence" between bodies is reduced as the bodies are: brought closer moved farther apart increased in charge held stationary
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 EMF does not depend on which of the following?
A. The magnetic field strength
B. The number of electrons in the magnetic field
C. The velocity of the wire in the field
D. The length of the wire in the magnetic field
Answer:
Explanation:
When a wire of length L is moved with velocity v , perpendicular to magnetic field B , EMF will be produced at its two ends . EMF can be calculated with the help of following expression
EMF = BLv
As per this formula , EMF produced will not depend upon number of electrons in the magnetic field.
So B is the right choice.
If the amount of force from the group on the left was 235 N, what is the amount of force from the group on the right
Answer:
(F = ma ) Newton's second law states that force is proportional to what is required for an object of constant mass to change its velocity. This is equal to that object's mass multiplied by its acceleration.
Why the temperature of a resistor increase when a current pass through it
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.
explain the forces of that affect the soccer balls path.
Answer:
yeah its correct
Explanation:
As the ball spins, friction between the ball and air causes the air to react to the direction of spin of the ball. ... Therefore, when a soccer player kicks the ball right of center the ball spins counter-clockwise and the Magnus force acts left, causing the ball to curve left.

The particles in gases are very far apart, so gases have a very low density.
what are newtons laws of motion?
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.

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.
