Explanation:
Answer:
None
Explanation:
Subatomic particles are the particles which are very smaller than the atoms. Elementary particles are the examples of subatomic particles.
Elementary particles are the particles without any sub-structure which means they are not composed of other particles.
The elementary particles are classified into three categories which are discussed below:
(1) Quarks: up, down, top, bottom, strange, and charm.
(2) Leptons: muon, muon neutrino, electrons, electron neutrino, tau, tau neutrino.
(3) Bosons: Z bosons, W bosons, Higgs, Gluon, photons.
Mesons are the particles which compose one quark and one anti quarks.
Therefore, in the given list there is no meson.
Answer:
29223.6J
Explanation:
Given parameters:
Mass of Piano = 852kg
Height of lifting = 3.5m
Unknown:
Gravitational potential energy = ?
Solution:
The gravitational potential energy of a body can be expressed as the energy due to the position of a body;
G.P.E = mgh
m is the mass
g is the acceleration due to gravity
h is the height
Now insert the given parameters and solve;
G.P.E = 852 x 9.8 x 3.5 = 29223.6J
Answer:
A: In all cases, the acceleration was the same.
Explanation:
I know this because its a clear obvious answer not only that it was one of my USA TESTPREP questions and it was right.
All you mainly have to do is the math - F=ma , In each case , the acceleration is 5 m/s squared
The number of times a standard quantity is present in the given physical quantity is called magnitude of a physical quantity
