Answer:
(2) −1 e
Explanation:
A quark is the lightest elementary particles which form hadron such as proton and neutron. A quark has fractional charge.
Up, charm and top quarks have 
charge where as down, strange and bottom quarks have 
charge.
The antiparticle of up quark is antiup quark and has charge 
charge.
The antiparticle of down quark is antidown quark and has charge 
charge.
An antibaryon is composed of two anti-up quark and one anti-down quark.
Net charge of the anti-baryon is:
Thus, antibaryon has -1e charge.
We can solve the problem by using the first law of thermodynamics:
where
is the variation of internal energy of the system
Q is the heat added to the system
W is the work done by the system
In this problem, the variation of internal energy of the system is
While the heat added to the system is
therefore, the work done by the system is
If you are given time and distance, you can determine power if you know
force. watts. energy. joules.
Answer is joules.
Power is defined as the rate of
doing work. Hence power = work / time then you obtain watts. Work is the
product of force and displacement (distance). Hence in formula, w = F x s. In
which the S.I unit of work is joule in the product. This is what you have to
obtain in order to calculate for power.
Thomson experiment he calculated the charge to mass ratio just be passing the fundamental charge through a tube
He calculated the charge to mass ratio just by finding the deflection of charge while it is passing through the constant electric field
so here we will use the deflection as following
let say it passes the field of length "L"
so here we have
now in the same time if it deflect by some distance
now by solving this equation we can find e/m ratio
so here correct answer will be
the electron's charge-to-mass ratio
Heat exhaustion is usually accompanied by a fever no higher than 104 degrees Fahrenheit, excessive thirst, nausea, fainting, cool and clammy skin, weakness, muscle aches, heavy sweating, slow heartbeat and dizziness. Heatstroke may develop following heat exhaustion if the condition is not treated.
