Answer:
64-14=50
Explanation:
try 64 - 14 and get your answer and its 50
Answer:
a) 2457J
b) 558W
c) 337N
Explanation:
Assuming dogs started from rest.
and the displacement is given by:
Using the energy conservation formula:
Because the motion started from rest the initial kinetic energy is zero, the motion occurred in-ground level so the gravitational energy is zero too.
the work done by the friction force is given by:
so:
The power is given by:
and the force exerted by the dogs:
Deleted this answer, sorry for any inconveniences that it may have caused.
Explanation:
From the experiment:
Number of protons = 74
Number of neutrons = 110
Number of protons in an element is the atomic number of the element. It is used to locate and position and element on the periodic table.
For a neutral or uncharged atom, the number of protons is the same as the number of electrons.
The element whose number of protons or atomic number if 74 is Tungsten
Mass number = 74 + 110 = 184g/mol
Answer:
Distance is the length of the path taken by an object whereas displacement is the simply the distance between where the object started and where it ended up.
