the energy of a water wave is most closely related to its

Answer:

Solon,

total mass (kg)= 100kg

height (h)= 25m

acceleration due to gravity = 9.8m/s²

so,

work done =m*g*h

= 100*9.8*25

= 24,500 joule

The work done by the crane in lifting the given mass of concrete to the given vertical height is 24500 Joules.

Work done is simply defined as the energy transfer that takes place when an object is either pushed or pulled over a certain distance by an external force. It is expressed as;

W = F × d

Where f is force applied and d is distance travelled.

Note that, the concrete is lifted upward, Weight of the concrete becomes mass multiply by acceleration due to gravity. g = 9.8m/s²

F = Weight = mg

Given that;

W = F × d

W = (mg) × d

W = ( 100kg × 9.8m/s² ) 25m

W = 980kgm/s² × 25m

W = 24500kgm²/s²

W = 24500J

Therefore, the work done by the crane in lifting the given mass of concrete to the given vertical height is 24500 Joules.

Answer:

[tex]A \to rad/s[/tex]

[tex]B \to rad/s^3[/tex]

Explanation:

[tex]\omega_z(t)=A + Bt^2[/tex]

Required

The units of A and B

From the question, we understand that:

[tex]\omega_z(t) \to rad/s[/tex]

This implies that each of [tex]A[/tex] and [tex]Bt^2[/tex] will have the same unit as [tex]\omega_z(t)[/tex]

So, we have:

[tex]A \to rad/s[/tex]

[tex]Bt^2 \to rad/s[/tex]

The unit of t is (s); So, the expression becomes

[tex]B * s^2 \to rad/s[/tex]

Divide both sides by [tex]s^2[/tex]

[tex]B \to \frac{rad/s}{s^2}[/tex]

[tex]B \to rad/s^3[/tex]

Answer:

Acceleration. When an external force acts on an object, the change in the object's motion will be directly related to its mass. This change in motion, known as acceleration, depends upon the object's mass and the strength of the external force.

Explanation:

The formula for the magnitude of a vector is

[tex]B_{mag}=\sqrt{(-1.33)^2+(2.81)^2}[/tex] and then round to the hundredths place:

3.11 m. Since we are in Q2, we can also find the direction of this vector:

[tex]tan^{-1}(\frac{2.81}{-1.33})=-64.7[/tex] but since we are in Q2, we add 180 degrees to the result, getting the angle to be 115.3

Answer:

La fuerza es la causa que provoca cualquier cambio en el movimiento o la geometría de los cuerpos. Un cuerpo puede aceptar muchas fuerzas al mismo tiempo, cuyo resultado será en cada punto una fuerza recomendada y un par recomendado. Cuando estas fuerzas se neutralizan entre sí, se dice que el cuerpo está en un estado de equilibrio.

En lo que respecta a los cuerpos libres, la fuerza es generalmente la causa de un cambio en su estado cinético, es decir, que los acelera o ralentiza. Esto también se aplica a su rotación, que puede acelerarse o desacelerarse. Para los cuerpos que no son libres de moverse en todas las formas, es decir, aquellos que están suspendidos en algún lugar y solo pueden moverse alrededor de un punto o eje o en una trayectoria predeterminada, así como aquellos que aplican fuerzas de fricción o reacciones generales de apoyo, nosotros reducir las fuerzas en puntos característicos. En el caso de los cuerpos no libres, la fuerza es la causa que provoca su movimiento o movilidad en relación con sus puntos de apoyo o conexión, o la que provoca su intenso estado, presión o deformación. La inercia de un cuerpo libre también permite que el cuerpo se someta a una tensión, presión o deformación intensas cuando se le aplican las fuerzas correspondientes.

Answer:

55.128kg

Explanation:

P= m×v

or, m=P/v = 430/7.8 = 55.128 kg

Answer:

55.13 kg

Explanation:

Momentum, P = m*v

P = m*v

m = P/v

m = 430/7.8

m = 55.13 kg

Answer:

The formula is correct.

Explanation:

The given expression is :

[tex]v^2=2gh[/tex]

Where

v is the velocity

g is acceletion due to gravity

h is height

Taking LHS,

The dimensional formula for [v] = [LT⁻¹]

[v²] = [L²T⁻²]

Taking RHS,

The dimensional formula for [g] = [LT⁻²]

The dimensional formula for [h] =[L]

2gh = [LT⁻²][L]

= [L²T⁻²]

So, LHS =  RHS

So, the given formula is correct dimensionally.

Explanation:

In Chemistry,a synthesis reaction is one that occurs when two or more reactants combine in such a manner that they form a single product.

Looking at the options, the only one where 2 reactants combine to form a single product is option C where Carbon reacts with Oxygen to form carbon (IV) oxide.

Answer:

R = 1.71 ohms

Explanation:

Two resistors are connected in parallel. There equivalent resistance is given by :

[tex]\dfrac{1}{R}=\dfrac{1}{R_1}+\dfrac{1}{R_2}[/tex]

Put all the values,

[tex]\dfrac{1}{R}=\dfrac{1}{3}+\dfrac{1}{4}\\\\R=1.71\ \Omega[/tex]

So, the resultant resistance of the circuit is equal to 1.71 ohms.

Answer:

Concave mirrors reflect light to a central point (converging)

Suppose the source is to the left of the  mirror in  question.

Parallel rays into the mirror are always reflected towards the focal point.

In the case of a concave mirror the real parallel rays pass thru the focal point.

If the mirror is convex the rays will diverge to the left and act as if they were emanating from the focal point to the right of the mirror.

Answer:

Input force of pulley system = 200 N

Explanation:

Given:

Mechanical advantage of pulley system = 5

Output force from pulley system = 1,000 N

Find;

Input force of pulley system

Computation:

Mechanical advantage = Output force / Input force

Mechanical advantage of pulley system = Output force from pulley system / Input force of pulley system

5 = 1,000 / Input force of pulley system

Input force of pulley system = 1,000 / 5

Input force of pulley system = 200 N

Answer: Pure-Tone Audiometry

Explanation:

Pure-tone audiometry refers to the behavioral test that is used in the measurement of hearing sensitivity. Pure tone audiometry an hearing test that's used in the identification of an individuals hearing threshold levels which is used in determining the degree of a hearing loss and then a basis for diagnosis will be provided.

Therefore, Pure-Tone Audiometry is a procedure that's used for measuring hearing sensitivity at certain frequencies using pure tones presented through an oscillator placed on the forehead or mastoid bone of the listener.
