where r is the radius

so

(4π × 7³) ÷ 3 =

(4π × 343) ÷ 3 =

Answer:

V=4 /3πr3

Answer:

A longitudinal wave travels by displacement of material objects.

Air (for instance) particles transmit waves by their oscillation

Space has no material particles to transmit these waves.

Answer:

A pure substance in the gaseous state contains more energy than in the liquid state, which in turn contains more energy than in the solid state. Particles has the highest kinetic energy when they are in the gaseous state.

The answer is energy it can be carried from one place to another.

please mark this as brainliest

Answer:

energy

Explanation:

In a wave phenomenon, energy can move from one location to another, yet the particles of matter in the medium return to their fixed position. A wave transports its energy without transporting matter. Waves are seen to move through an ocean or lake; yet the water always returns to its rest position.

Answer:

I'm sorry I don't have a answer but I like your pfp

Answer:

1)So, the mass(m) of the tv is 75kg and the scale(weight)=825 N therefore you devide the weight by the mass which is equal to 11m/s^2

2)First things first you need to know the gravitational force here on earth which is 9.8(approximately 10) I will sove for 9.8 and 10 so you can choose

the fish has a mass of 2.4kg and the gravity= 9.8 so the weight is equal to the mass*gravity= 23.52

now if you use 10 as the gravity= 2.4*10= 24

3) here the weight is 250N and gravity is 9.8(10) so we just devide the weight by the gravity= 250/9.8= 25.51

                         250/10= 25( if gravity is 10)

Answer:

Explanation:

12.since W=mg where m is mass and g which is accelaration due to gravity,

  g=825N/75kg

  g=11 m/s^2

13.W= 2.4kg * 9.81m/s^2

      =23.544kg m/s^2=23.544N

14.m=250N/9.81ms^-2

       =25.48kg

Answer:

The force is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

I don't understand ,I'm sorry

Hi there!

We can use the following (derived) equation to solve for the final velocity given height:

vf = √2gh

We can rearrange to solve for height:

vf² = 2gh

vf²/2g = h

Plug in the given values (g = 9.81 m/s²)

(13)²/2(9.81) = 8.614 m

We can calculate time using the equation:

vf = vi + at, where:

vi = initial velocity (since dropped from rest, = 0 m/s)

a = acceleration (in this instance, due to gravity)

Plug in values:

13 = at

13/a = t

13/9.81 = 1.325 sec

Answer:

Friction braking is the most commonly used braking method in modern vehicles. It involves the conversion of kinetic energy to thermal energy by applying friction to the moving parts of a system. The friction force resists motion and in turn generates heat, eventually bringing the velocity to zero.

the answer is gravity

gravity pulls things down

Calibration can be defined as the way an instrument is adjusted such that the measurement the instrument gives after calibration is precise and accurate.

One effective way to calibrate a thermometer is the use of ice water.

A thermometer can be defined as the instrument used to measure the temperature of a person or a substance.

A thermometer should be calibrated regularly in order to maintain a high level of precision and accuracy.

Answer

both earthquakes and tsunamis have waves  

Explanation:

Tsunamis are caused by earthquakes, underwater land slides, volcanic eruptions, and land sloping into the ocean. An earthquake is rapid shaking of the earths surface. It's no wonder earthquakes cause mass destruction, because they occur when two plates collide. Also earthquakes occur more often than tsunamis do.
