6 0

Answer:

weight =m x g =2kg × 10m/s 2 = 20N

<h3>Formulas:</h3>

weight = m × gravity

=unit for weight is newtons

Mass=weight ÷ gravity

= unit for mass is kilograms

Gravity=weight ÷ mass

=unit for gravity is 10m/sec 2

¿Por qué si cargas a uno de tus compañeros por cierto tiempo no estás realizando un trabajo mecánico?
VladimirAG [237]

Answer:

I will answer this in English, we can translate it to:

Why if you charge a mate by an amount of time you are not doing work?

This happens because work is defined as the displacement done by a force:

W = d*F

where W is work, d is the distance, and F is the force.

This means that the amount of time that you are charging your mate does not affect the mechanical work, the only time that you are doing work is when you are lifting him.

What is the kinetic energy of a 7.56 kg bowling ball that is rolling at a speed of 2 m/s ?
postnew [5]

Answer:

K.E=?

Mass=7.56 kg

Velocity=2m/s

Solution::

K.E = 1/2mv^2

K.E=0.5*7.56*(2)^2

K.E= 0.5*7.56*4

K.E=15.12 joules.

What type of electrical cord has a ground?<br><br> 3 pronged cord<br><br> 2 pronged cord
Kisachek [45]
<h3>Answer: A) 3 pronged cord</h3>

Explanation:

One prong is known as the hot wire, where the electricity comes in, while the second prong is the neutral wire and electricity leaves. Recall that a circuit must be made for electrons to flow. This means that electrons enters your house through the transmission wires and then the electrons leave along the same lines they entered (just along a different wire).

This set up describes a 2 pronged cord. Adding a third prong allows for a grounding to happen. In the event of an electrical surge, when too many electrons are flowing, disaster is likely to happen without some kind of safety features. The grounding prong allows electrons to seek the ground. You can think of it like a drain in a bathtub when too much water gets in the tub.

Define Wavelength<br> please and quick thx!
Nitella [24]

Wavelength is defined by Velocity of the wave by Frequency

Symbolically

\\ \ast\bull\rm\longmapsto \lambda=\dfrac{c}{v}

  • C is speed of wave
  • v is frequency
  • lambda is wavelength
