Answer:

The correct answer will be option-B

Explanation:

A scientific law is a statement which provides the description of the natural event in the form of facts so represents the factual description.

The scientific law becomes established only after the repeated experiment by another researcher provides the evidence and supports the scientific statement. The law once become established never changes and remains the same, unlike the scientific theory.

In the given question, the gravity acts on every object have been proved by the repeated experiments` by another researcher and hold true since the time has been stated for the first time.

Thus, Option-B is the correct answer.

6.A truck is carrying a steel beam of length 13.0 m on a freeway. An accident causes the beam to be dumped off the truck and sli
labwork [276]

The magnitude is 13.12 mV.

The steps are attached below.

<h3>How do you find the magnitude of an induced emf?</h3>

The standard SI unit of the magnetic field is the tesla (T). As an end result, we can use these equations and the equation for an induced emf due to changes in magnetic flux, ϵ=−NΔϕΔt ϵ = − N Δ ϕ Δ t, to calculate the importance of a precipitated emf in a solenoid.

The magnitude of the precipitated contemporary depends on the rate of trade of magnetic flux or the fee of reducing the magnetic area strains.

Two people push on a boulder to try to move it. The mass of the boulder is 825 kg. One person pushes north with a force of 64 N.
stira [4]

Answer:

0.09 m/s²

Explanation:

Acceleration: This can be defined as the rate of change of velocity.

The S.I unit of acceleration is m/s².

From the question, expression for acceleration is given as

F' = ma  

Using Pythagoras Theory,

√(F₁²+F₂²) = ma................... Equation 1

Where F₁ = Force of the First person on the boulder, F₂ = Force of the Second person on the boulder, F' = resultant force acting on the boulder, m = mass of the boulder, a = acceleration of the boulder.

make a the subject of the equation

a = √(F₁²+F₂²) /m................ Equation 2

Given: m = 825 kg, F₁ = 64 N, F₂ = 38 N,

Substitute into equation 2

a = [√(64²+38²)]/825

a = {√(5540)}/825

a = 74.43/825

a = 0.09 m/s²

What happens to a wave when it is reflected?
STALIN [3.7K]

Answer:

Reflection involves a change in direction of waves when they bounce off a barrier. Refraction of waves involves a change in the direction of waves as they pass from one medium to another. Refraction, or the bending of the path of the waves, is accompanied by a change in speed and wavelength of the waves.

The density of diamond is 3.51 g/cm3 . the international (but non-si) unit for weighing diamonds is the "carat" (1 carat = 200 m
mixer [17]

To calculate the volume of the diamond, we use the formula

\rho =\frac{m}{V}

Here, \rho is the density and its value given 3.51 g/cm^3

and m is mass and its value given0.87 carat.

1 carat = 200 mg = 0.200 g

So mass of the diamond, m= 0.87 carat \times 0.200 g/carat = 0.174 g

Substituting these values in above equation we get,

\rho =\frac{0.174 g}{3.51 g/cm^3} =0.0495 cm^3

Thus the volume of given carat diamond is 0.0495 cm^3.
