In a free body diagram all the forces are depicted as pointing _______ the central box

Answers

Answer 1

Answer:

There are three forces acting upon the system - the gravity force (the Earth pulls down on the 15.0 kg of mass), the normal force (the floor pushes up on the system to support its weight), and the applied force (the hand is pushing on the back part of the system).

The pressure at the bottom of a lake is 300 000 N/m2 more than at the surface of the lake. The lake is fresh water (density = 1000 kg/m3).

Answers

Answer:

h = 30.61 m

Explanation:

In this problem they indicate the pressure at the bottom of the lake and the density of the water, for which they must ask what is the depth of the lake.

The pressure is given by the expression

P = [tex]P_{atm}[/tex] + rho g h

P - P_{atm} = rho g h

The gauge pressure value is P- P_{atm} = 3 105 N / m²

h = [tex]\frac{P - P_{atm}}{ \rho \ g}[/tex]

let's calculate

h = [tex]\frac{3 \ 10^5}{1000 \ 9.8}[/tex]

h = 30.61 m

what is the correct equation for calculating kinetic energy?

1. kinetic energy = potential energy - total energy
2. kinetic energy = total energy - potential energy
3. kinetic energy = 1/2 x (total energy + potential energy)
4. kinetic energy = potential + total energy

Answers

Answer:

2. kinetic energy = total energy - potential energy

Explanation:

The total energy of a system is the addition of kinetic and potential energy of the system. Kinetic energy can be regarded as form of energy posses by an object when it's in motion

Total energy = kinetic energy + potential energy

(If we make Kinectic energy the subject of the formula, we have)

kinetic energy = total energy - potential energy

According to FDR, who should be held responsible for the crisis? 69 POINTS PLEASE ANSWER!!!!!!!!!!!!!!!!!!!!!!!!!!!!! The first postage stamp, the "Penny Black," was printed and used in England in 1840. The stamp was called the "Penny Black" because it was printed in black ink and was sold for a penny. Mail was sent and received long before the first stamp, but it was the receiver who had to pay for the mail, not the sender. Since some people were unable to pay to receive their mail, the idea of the postage stamp was born.In 1845, five years after England's "Penny Black," the first stamp was printed in the United States of America. Two years later, on July 1, 1847 the first official U.S. postage stamps were issued featuring the portraits of our first postmaster and our first President. The five cent value paid for postal service up to a distance of 300 miles. The stamp, printed in blue, has a catalog value of hundreds of dollars today. A used or canceled copy of this stamp is worth at least half as much as an unused stamp. This stamp was issued imperforate (unperforated) and had to be cut apart with scissors. The adoption of adhesive stamps opened up the development of today's extensive postal system.Since 1845, the United States has printed more than 3,000 different kinds of stamps. Gradually, all of the world's countries began to issue stamps.Several kinds of postage stamps are printed. Some of the most interesting are the commemoratives. A commemorative stamp honors anniversaries, important people, or special events. It is usually on sale at the post office only for a short time.A more common stamp is called a regular issue. Regular issue stamps are printed in greater numbers, and can be obtained for a longer period of time. They are sold in stamp machines as well as in the post office.Other less common stamps are airmail stamps, special delivery stamps, and envelope stamps. If you have ever seen a postage stamp album of the United States, you will know that it has spaces to put all of these stamps.Submit your persuasive writing about stamp collecting.
