Show your calculations.

Answers

The actual mass of a 1 cm² piece of copy paper is determined as 0.0074 g.

Area of the sheet of paper in square centimeters

Area = Length x Width

Area = (11 x 2.54 cm) x (8.5 x 2.54 cm)

Area = 603.22 cm²

what would happened if there is no invented of machine?​

Answers

if there were no invention of machines then life would have been more difficult and simple works could be hard to do. Even now we are using our phones, sitting in a AC room interacting to eachother from different places. without the invention of machines simple things like transportation would have been difficult. There would be horses and donkey for the transportation. There would be no electricity,no internet, no transportation, not even c computers or mobile etc. The market for business will be smaller, the knowledge and news about world would be less.

so the problem would have been bigger than we can imagine. But one thing is that nature could survive lot more compared to what we have done till now by destroying nature.

A downward force of magnitude 5 n is exerted on the book by the force of.

Answers

Answer:

Gravity    (perhaps)

Explanation:

Without a further description or a diagram, I would guess the downward force would be gravity.

Gravity exerts a downward pull on the book with a magnitude of 5 n. the correct answer would be option (A) gravity.

What is the force by gravity?

The attraction that the earth, moon, or other immensely big object has on another object is referred to as gravity. By definition, this is the object's weight. Gravity affects all items on Earth and is directed "downward" towards the earth's center. On Earth, gravity gives physical objects weight, while the Moon's gravity causes sublunar tides in the seas (the corresponding antipodal tide is caused by the inertia of the Earth and Moon orbiting one another).

Gravity also plays a significant role in biology, such as regulating plant development through gravitropism and controlling fluid circulation in multicellular animals.

According to research into the consequences of weightlessness, gravity may have a role in immune system function and cell differentiation inside the human body.

Thus, Gravity exerts a downward pull on the book with a magnitude of 5 n.

where does the potential energy of rocket goes when it escape from the influence of the earth

Answers

The potential energy of a rocket increases when its escapes from the influence of the earth. It increases when it escapes the earth's boundary.

What is escape speed?

Escape velocity or escape speed is the minimum speed required for a free, non-propelled object to escape from the gravitational pull of the main body and reach an infinite distance from it in celestial physics.

It is commonly expressed as an ideal speed, neglecting atmospheric friction.

If a spacecraft is launched from the moon at the escape speed of the earth then the value of escape speed will be the difference in both the velocities.

An object's height above the zero position directly relates to its gravitational potential energy.

The kinetic energy of motion is converted into gravitational potential power as your rocket ascends.

The rocket possesses gravitational potential energy as it climbs because it is becoming farther away from the Earth's surface, much as a positive and negative charge moving apart.

The potential energy of a rocket increases when its escapes from the influence of the earth. It increases when it escapes the earth's boundary.

Home heating systems usually work in the following way: When the furnace warms a house above the set temperature of the thermostat, the thermostat is triggered and shuts off the furnace. When the temperature in the house drops below the set temperature, the furnace comes back on. True or false: Home heating systems work through negative feedback.

Answers

Home heating systems work through negative feedback by regulating the temperature through thermostat.

How home heating systems work through negative feedback?

In thermostat, when the temperature of the room environment increases by the negative feedback system the furnace gets turn off, allowing the room to get to its normal temperature and when the temperature lower down it turns on again and maintain the temperature in equilibrium state.

What do comets and asteroids have in common?

Answers

Answer:

Asteroids and comets have a few things in common. They are both celestial bodies orbiting our Sun, and they both can have unusual orbits, sometimes straying close to Earth or the other planets. They are both “leftovers” — made from materials from the formation of our Solar System 4.5 billion years ago. But there are a few notable differences between these two objects, as well. The biggest difference between comets and asteroids, however, is what they are made of.

While asteroids consist of metals and rocky material, comets are made up of ice, dust, rocky materials and organic compounds. When comets get closer to the Sun, they lose material with each orbit because some of their ice melts and vaporizes. Asteroids typically remain solid, even when near the Sun.

Right now, the majority of asteroids reside in the asteroid belt, a region between the orbits of Mars and Jupiter which may hold millions of space rocks of varying sizes. On the other hand, the majority of comets are in the farthest reaches of our Solar System: either 1. in the Kuiper Belt — a region just outside the orbit of the dwarf planet Pluto that may have millions of icy comets (as well as many icy dwarf planets like Pluto and Eris); or 2. the Oort Cloud, a region where trillions of comets may circle the Sun at huge distances of up to 20 trillion kilometers (13 trillion miles).
