2) how do you measure the volume of an irregular solid ? explain an experiment with diagram.​

Answers

Answer:

1. While boiling replace the cap and allow it to cool. Vapours inside condense and form water creating vacuum above them. Observation - The can crumbles due to air pressure from outside. This proves that air exerts pressure.

2. Measure the volume of the liquid displaced when the object is submerged. Measure the initial volume of water in graduated cylinder. Submerge the irregular object. Measure the final volume of the water.

— The difference between the initial volume and the final volume is the volume of the object.

An automobile travels the first half of an 80.0 mi trip at 20.0 mi/h and the second half of the trip at 40.0 mi/h. What is the average speed for the entire trip?

Answers

This question involves the concepts of uniform speed motion and average speed.

The average speed for the entire trip is "26.67 mi/h".

First, we need to find out the total time taken for the entire trip. For that purpose, we will break the entire trip into two halves of uniform speed motion:

[tex]Total\ Time = t_1+t_2\\\\Total\ Time = \frac{s_1}{v_1}+\frac{s_2}{v_2}\\\\Total\ Time = \frac{40\ mi}{20\ mi/h}+\frac{40\ mi}{40\ mi/h}\\\\Total\ Time = 2\ h + 1\ h\\Total\ Time = 3\ h[/tex]

Now, the average speed for the entire trip will be:

[tex]Average\ Speed = \frac{Total\ Distance}{Total\ Time}\\\\Average\ Speed =\frac{80\ mi}{3\ h}[/tex]

Average Speed = 26.67 mi/h

A ball is thrown upward with an initial velocity of 22.0 m/s. If
the gravitational acceleration is –9.81 meters per second
squared, what is the maximum height the ball will reach?
Select one:
2.24 m.

24.7 m.


4.48 m.


49.4 m.

Answers

The maximum height reached by the ball during the upward motion  is 24.7 m.

The given parameters;

initial velocity of the ball, u = 22 m/s

The maximum height reached by the ball is determined using the third kinematic equation as shown below;

v² = u² - 2gh

where;

v is the final velocity of the ball at the maximum height = 0h is the maximum height attained by the ball

0 = u² - 2gh

2gh = u²

[tex]h = \frac{u^2}{2g} \\\\h = \frac{22^2}{2(9.8)} \\\\h = 24.7 \ m[/tex]

Thus, the maximum height reached by the ball during the upward motion  is 24.7 m.

3. Explain what forces the Egyptians had to overcome when building the pyramids

Answers

Answer:

(Hope this helps can I pls have brainlist (crown)☺️)

Explanation:

But how did the Egyptians overcome the extreme friction of dragging such massive things through the sandy desert, some of which weighed more than 9,000 pounds? Researchers at the University of Amsterdam have come up with a very simple solution to the friction problem: they utilised water.

The pyramids were not built by slaves, contrary to common perception. Archaeologists discovered the ruins of a purpose-built town for the hundreds of labourers who constructed the renowned Giza pyramids about 4,500 years ago.

The Egyptians had to overcome the force of friction while dragging the big blocks of stone and the force of gravity while uplifting the large stone structure to a greater height when building the pyramids.

What is friction?

Friction is a type of force that resists or prevents the relative motion of two physical objects when their surfaces come in contact.

The friction force prevents any two surfaces of objects from easily sliding over each other or slipping across one another. It depends upon the force applied to the object.

Thus, while constructing the pyramids, the Egyptians had to fight against the forces of gravity and friction as they lifted the massive stone edifice to a greater height.

A force unit is defined as the product of a mass unit and a unit of

acceleration.


time.


velocity.

displacement.

Answers

Answer:

A force unit is defined as the product of a mass unit and a unit of acceleration.

Answer:

Force can be defined as a push or a pull that changes or tends to change the state of rest or uniform motion of an object or changes the direction or shape of an object.

Explanation:

Force = M (Mass) * A (Acceleration)

The SI unit of Mass = KG

S.I. unit of acceleration is m/sec/sec = m/sec2

Hence, Unit of force is Kg m/Sec2

Since force is used so often, S. I. gives this unit a special name:

1 Newton = 1 kg m/sec2
