I believe the color would be yellow but it would also depend on the color of the toy.
Answer:
489 J
Explanation:
According to the first law of thermodynamics:-
Where,
U is the internal energy
q is the heat
w is the work done
From the question,
q = + 565 J (+ sign as the heat is being absorbed)
The expression for the calculation of work done is shown below as:
Where, P is the pressure
is the change in volume
From the question,
= 0.85 - 0.10 L = 0.75 L
P = 1.0 atm
Also, 1 atmL = 101.3 J
So,
(work is done by the system)
So,
Answer:
e must have the charge of the particle
Explanation:
In this experiment, the particles that the cathode rays are found where from an electric field and another magnetic field, for the particle to pass without deviating the magnetic force must have the same modulus of the entricar force, and be in the opposite direction.
the expression for the magnetic force is
F_m = q v xB
the expression for the electric force is
F_e = q E
when warning the check two formulas we must have the charge of the particle
The acceleration due to gravity changes as we move away from Earth, and the expression for gravitational potential energy must reflect this change. The total energy of a system is the sum of kinetic and gravitational potential energy, and this total energy is conserved in orbital motion.
