The measure of life in hours and wind is my enemy states that is a candle as it states I serve you by expiring.

A candle is a stick made of wax and forms an inflammable solid substance. It has a light and gives some sort of fragrance.

It can also provide a medium to heat or to save time, as the candle is burnt the oxygen is consumed and carbon id is given out. As the statement speaks about the wind which is my enemy, it states the nature of the candle that dies out immediately.

Answer:

d = 1.65 m

Explanation:

Given that,

The speed of a ball, v = 3 m/s

A ball rolls a level table that is 1.5 m above the floor.

We can find how long the ball is in free fall. We can use the second equation of kinematics as follows :

[tex]s=ut+\dfrac{1}{2}gt^2[/tex]

u is the initial speed in the vertical direction

So,

[tex]s=\dfrac{1}{2}gt^2\\\\t=\sqrt{\dfrac{2s}{g}} \\\\t=\sqrt{\dfrac{2\times 1.5}{9.8}} \\\\t=0.55\ s[/tex]

Now, using the formula of velocity.

[tex]v=\dfrac{d}{t}\\\\d=vt\\\\d=3\times 0.55\\\\d=1.65\ m[/tex]

So, the landing spot is at 1.65 m from the table.

Answer:

With all of that information, he's telling us the train's VELOCITY.

Explanation:

Velocity is a vector quantity made of two parts: speed and direction.

Answer:

Potential Energy

Answer:

Force(Romeo moving) = 5,000 N

Explanation:

Given:

Mass of horse = 900 kg

Acceleration = 20 km/hr

Find:

Force(Romeo moving)

Computation:

Acceleration = 20 km/hr

Acceleration in m/s = 20 / 3.6 = 5.555556 m/s²

Force = m x a

Force(Romeo moving) = 900 x 5.555556

Force(Romeo moving) = 5,000 N

Answer:

Answer:

56000kgm/s

Explanation:

Momentum = Mass * Velocity (both in standard unit)

Therefore, the car's momentum = 1400 * 40 = 56000kgm/s (or 56000Ns)

Answer:

It measure the effort it takes for an object to move

Explanation:

Work done is the force applied to move a body through a particular distance.

It can also to be said to be a measure of the effort it takes for an object to move.

The unit of work done is in Joules.

 To find work done, we use the expression below:

       Work done  = Force x distance

The equation should be used to calculate the speed of a wave is speed = frequency x wavelength.

The speed of a wave is calculated by the equations: V = λ . f or V = λ/T, and the unit of measurement is m/s. This speed depends on the medium: in gaseous media, the speed is lower than in solid media.

The equation should be used to calculate the speed of a wave is speed = frequency x wavelength.

Wave speed is the movement of a progressive wave, which is an energy-moving disturbance that takes the shape of an oscillation and moves from one place to another.

The wavelength and frequency of a wave both affect its speed. A wave's speed is a crucial factor because it enables us to estimate how quickly the wave will disperse in the medium, which is the substance or material that will carry it.

This is the water in the case of ocean waves and the air in the case of sound waves. The kind of wave and the physical properties of the medium in which it is flowing also affect a wave's velocity.

Therefore, The equation should be used to calculate the speed of a wave is speed = frequency x wavelength.

sheet of metal required = 120.95 cm^2

Explanation:

Answer:

Given :-

A closed cylindrical tank of radius 3.5 m and height 2 m is made from a sheet of metal.

To Find :-

How much sheet of metal is required.

Formula Used :-

[tex]{\red{\boxed{\large{\bold{T.S.A\: of\: cylinder\: =\: 2{\pi}r(r + h)}}}}}[/tex]

where,

r = Radius

h = Height

Solution :-

Given :

Radius = 3.5 m

Height = 2 m

According to the question by using the formula we get,

⇒ [tex]\sf T.S.A =\: 2 \times \dfrac{22}{7} \times 3.5(3.5 + 2)[/tex]

⇒ [tex]\sf T.S.A =\: 2 \times \dfrac{22}{7} \times 3.5(5.5)[/tex]

⇒ [tex]\sf T.S.A =\: 2 \times \dfrac{22}{7} \times 3.5 \times 5.5T.S.A=2×722×3.5×5.5

⇒ \sf T.S.A =\: 2 \times \dfrac{22}{7} \times 19.25[/tex]

⇒ [tex]\sf T.S.A =\: 2 \times 60.5[/tex]
