Answer:

W'=125.44 N

Explanation:

The weight of a person on the surface of Earth is 784 N

Weight is given by :

W = mg

m is mass of the person and g is acceleration due to gravity on the surface of Earth (10 m/s²)

$m=\dfrac{W}{g}\\\\m=\dfrac{784}{10}\\\\m=78.4\ kg$

The acceleration due to gravity on the surface of Moon, g' = 1.6 m/s²

Weight of the person on the moon is :

W'=mg'

$W'=78.4\ kg\times 1.6\ m/s^2\\\\W'=125.44\ N$

Hence, the person would weigh 125.44 N on the Moon.

Elanso [62]

Answer: 981 Pa

Explanation:

1) Data:

m = 60 kg

S = 6000 cm²

P = ?

2) Formulas

i) F = peso = mg

ii) P = F / S

3) Solution

i) F = 60kg × 9.81 m/s² = 588.6 N

ii) P = F / S

First, convert 6000 cm² to m²: 6000 cm² × 1m² / (100cm)² = 0.6 m²

Now, plug in the values and do the operations: P = 588.6N / 0.6m² = 981 Pa

Describe the factors that determine power in your own words (not from a website)

Bond [772]

As it was categorized in the physics category it must be the mechanical power.

Power is basically the amount of work done per unit time or in simpler words the amount of energy transferred per unit time.

The SI unit for power is Watt. Which is basically J/s or Nm/s as wor has the unit of Nm.

In electrical components power can also be categorized as the amount voltage supplied multiplied by the current passed through the component.

6. Can an object accelerate, but not speed up or slow down?<br> Explain:

FromTheMoon [43]

Answer:

yes, though the speed may stay constant, the direction will change. so for example, you're going 70mph on the freeway, but you have to take the exit on your right (the exit continues on to a different freeway), you're not going to speed up or slow down, you'll change your direction which is still accelerating.

Explain what physicists mean when they say that the de Broglie wavelength relates to the probability distribution wave function.

Ksju [112]

Answer:

Because it unites particle and wave nature.

Explanation:

De Broglie wavelength can be defined as the,

$\lambda =\frac{h}{mv}$

Here, h is planks constant, m is the mass of electron, v is the velocity of electron.

Since the de Broglie wavelength can behave like the photon wavelength with respect to the momentum

It unites particles and waves nature ,so De Broglie wavelengths is probability waves associated with the wave function according to physicists.
