The sound of science​

Answer»

Answer:

SOUND is created when something VIBRATES and sends waves of energy (vibration) into our ears. The vibrations travel through the air or another medium (solid, liquid or gas) to the ear. The STRONGER the vibrations, the louder the sound. Sounds are fainter the further you get from the sound SOURCE.

What happens to the shape of water when we pour thesame volume of water in different containers of differentshapes?​

Answer»

Answer:

The movement of the particles causes the liquid to be variable in shape. LIQUIDS will flow and fill the lowest portion of a CONTAINER, taking on the shape of the container but not changing in VOLUME. The limited amount of space between particles MEANS that liquids have only very limited compressibility.

Two bodies have masses in the ratio 3 : 4.When a force is applied on first body, itmoves with an acceleration of 6 m/s2. Howmuch acceleration the same force willproduce in the other body ?

Answer»

Answer:

Let us consider the two MASSES as 3x and 4X respectively.Given acceleration of first body as 6.

F=m×a

F=3x×6=18x

As we are applying same force for the SECOND body,

18x=4x×a

⇒a=18/4=4.5m/s

HENCE acceleration is 4.5m/s

A metal cylinder has a mass of 6.20 g. The density of the cylinder is 21.0 g/mL. What is its volume?

Answer»

AnsWer :

  • We're given in the question that, a metal cylinder has a MASS (m) of 6.20 g.
  • It is ALSO given that, the density (ρ) of the cylinder is 21.0 g/mL.
  • We are asked to find the VOLUME (v) = ?

For CALCULATING the volume (v) we need to use the given below formula :

↠ρ = m/v

Rearranging the above formula we get :

↠v = m/ρ

Now, simply PLUG in the known values in the above formula :

↠v = m/ρ

↠v = 6.20 g/(21.0 g/mL)

v = 0.295 mL

The volume of metal cylinder is 0.295 mL.

1. Differentiate between mass and weight of a body.2. Find why the weight of objects reduce on moon?Answer if you know, please.If answer was correct will mark as brainliest.

Answer»

Answer:

The difference between MASS and weight is that mass is the amount of matter in a material, while weight is a measure of how the force of gravity acts upon that mass. Mass is the measure of the amount of matter in a body. ... Weight USUALLY is DENOTED by W. Weight is mass multiplied by the acceleration of gravity (g).

WHAT IS MASS IN PHYSICS. IN SIMPLE WORDS ALSO YOU CAN USE HINDI​

Answer»

Answer:

Mass, in physics, QUANTITATIVE measure of inertia, a fundamental PROPERTY of all matter. It is, in effect, the RESISTANCE that a body of matter offers to a change in its speed or position upon the application of a force.

1. Calculate Load Distancea) Effort = 500 Newton, Load = 2000 Newton, Effort Distance = 4 Meter,Load Distance = ?

Answer»

Given,

EFFORT (E) = 500 N

Load (L) = 2000 N

Effort Distance (Arm) = 4 m

M.A = L/E

= 2000/500

= 4

If we assume that M.A remains the same,

M.A = Effort Arm/Load Arm

4 = 4/Load Arm

Load Arm = 1 m

The Load Arm/Distance is 1 m.

I hope this HELPS.

Define Acceleration ✨​

Answer»

Answer:

ACCELERATION is the RATE of change of velocity. USUALLY, acceleration means the speed is changing, but not always. When an object moves in a CIRCULAR path at a constant speed, it is still accelerating, because the DIRECTION of its velocity is changing.

Decide what the useful and wasted energy transformations are for these devices:a refrigerator, an aeroplane, a solar panel, a loudspeaker, a computer.please ans: asap.

Answer»

Answer:

1. Refrigerator- In a refrigerator, electrical energy is converted into mechanical energy by a motor.

2. an aeroplane- the mechanical energy is converted into kinetic energy. As the airplane goes higher, the mechanical energy is changed into gravitational potential energy. While flying, some energy is lost through drag to thermal (heat) energy and sound energy.

3. a solar panel- When photons shine on a solar cell, they are ABSORBED by the cell. If the photons have enough energy they cause the cell to release electrons. If the photons do not have enough energy, their energy is TRANSFORMED into heat energy

4. a loundspeaker- Speakers work by converting electrical energy into mechanical energy (motion). Themechanical energy compresses air and converts the motion into sound energy or sound pressure level (SPL)

5. computer- Mostly from electrical to heat. The electrical may come from chemical in the form of a battery. A very SMALL proportion of the electrical energy is converted to light (the screen) and sound, and some kinetic in the rotation of fans or hard disk platters.

In your scrapbook, State the characteristics of solid, liquid and gases by picking an example from the objects around you.

Answer»

MATTER typically EXISTS in one of three STATES: solid , liquid , or GAS . The state a given substance exhibits is also a physical property. Some substances EXIST as gases at room temperature (oxygen and carbon dioxide), while others, like water and mercury metal, exist as liquids. Most metals exist as solids at room temperature. All substances can exist in any of these three states. In addition to existing in one of the three states, matter can also undergo a change of state. A change of state occurs when matter is converted from one state to another state for example when a liquid is converted to a gas or a solid is converted to a liquid.
