3 0

Answer: A. It follows one prescribed sequence of steps.

Explanation:

A scientific method can be define as the procedure which is required to be followed so as to prove the cause of a scientific phenomena. The scientific method usually consist of steps of experimentation procedures which are performed under controlled conditions so as to avoid any error in the observation as well as in the results. The scientific method is necessary to relate the experimental conditions with the nature.

Considering that microwave ovens radiate at 2.45 GHz, how would you respond to the debate
vlada-n [284]
On the off chance that a 2.45 GHz microwave flag is by one means or another radiating from your microwave oven, that is exceptionally perilous and you ought to have it settled or supplanted promptly. A 1000 Watt microwave oven radiating energy into the nearby environment can, contingent upon conditions, make you lose awareness in around 12 to 15 minutes of presentation at a separation of around 10 feet.

Neo and morpheus's masses have gained a velocity not equal to zero which means their momentum is now
aniked [119]

Answer:

has increased

Explanation:

Since Neo and Morpheus's masses have gained velocity not equal to zero, their momentum now has increased.

A gain in velocity increases the momentum of a body.

 Momentum is the quantity of motion a body possesses.

It is mathematically expressed as:

 Momentum  = mass  x  velocity

Momentum is directly proportional to mass and velocity

In a lab, you perform a double slit experiment to measure the wavelength of a particular laser. When aimed at two slits spaced b
bekas [8.4K]

Answer:

The wavelength of the laser light is 572 nm.

Explanation:

Given that,

Distance between slit d= 0.22 mm

Distance of screen D= 0.5 m

Bright lines = 10

Width y= 1.3 cm

We need to calculate the wavelength

Using formula of young

y=\dfrac{n\lambda D}{d}

\lambda=\dfrac{dy}{nD}

Put the value into the formula

\lambda=\dfrac{0.22\times10^{-3}\times1.3\times10^{-2}}{10\times0.5}

\lambda=5.72\times10^{-7}\ m

\lambda=572\times10^{-9}\ m

Hence, The wavelength of the laser light is 572 nm.

You and your 3 friends are driving down the road. All the wheels go flat at the exact same time, that's not good. You have to us
mel-nik [20]

Answer:

Workdone = 8400 Nm

Explanation:

Given the following data;

Force = 2100 N

Distance = 4 meters

To find the work done;

Workdone = force * distance

Workdone = 2100 * 4

Workdone = 8400 Nm

Therefore, the amount of work done on the car is 8400 Newton meters.

Which combination of vectors would form the resultant vector 6.5 m 18° N of E when added together?
Vaselesa [24]

r = (x, y) + (6.5*cos(18°)-x, 6.5*sin(18°)-1)

v1= (x, y), v2=(6.5*cos18°-1, 6.5*sin18°-1)

You can choose any real numbers for x and y. See attached for a little more depth.
