<h3><u>Answer;</u></h3>

Gamma rays

Gamma rays are the radioactive emissions with the most penetrating power.

<h3><u>Explanation;</u></h3>
  • <em><u>Alpha, beta particles and gamma rays are the three main types of radiations emitted by unstable or radioactive isotopes.</u></em>
  • <em><u>Gamma radiation does not consist any particles but contain a photon of energy emitted from an unstable nucleus. Gamma radiation has no charge or mass, thus can travel farther through air than the other radiations.</u></em>
  • <em><u>Gamma is the most penetrating radiation with alpha being the least penetrating.</u></em>

The mass of an object is 60kg on the surface of the earth what will be its weight on the surface of the moon
iris [78.8K]

Answer:

Wm = 97.2 [N]

Explanation:

We must make it clear that mass and weight are two different terms, the mass is always preserved that is to say this will never vary regardless of the location of the object. While weight is defined as the product of mass by gravitational acceleration.

W = m*g

where:

m = mass = 60 [kg]

g = gravity acceleration = 10 [m/s²]

But in order to calculate the weight of the body on the moon, we must know the gravitational acceleration of the moon. Performing a search of this value on the internet, we find that the moon's gravity is.

gm = 1.62 [m/s²]

Wm = 60*1.62

Wm = 97.2 [N]

relative to the floor, what potential energy does a 2.5 kg package have that sits on a shelf 2.2 m high
Kobotan [32]
Potential energy = mass x acceleration due to gravity x height
                             =    2.5 x 9.8 x 2.2
                             =          53.9 J.

Hope this helps!

Answer: static electricity

Explanation: The movement of charged particles through a wire or other medium is called current or electricity. There is also static electricity, which results from an imbalance or separation of the positive and negative charges on an object. Static electricity is a form of electrical potential energy
