Answer:
tension is 37.8 N
Explanation:
given data
mass of bar m1 = 2 kg
length of bar L = 1.4 m
suspended mass m2 = 5 kg
suspended object position length L2 = 0.8 m
to find out
tension
solution
we consider here bar is connected with hinge and
we know here system is equilibrium
so here net torque will be zero at joint
and mass 2 kg act at L1 = 1.4 /2 = 0.7 m
so torque = m1×g× ( L1 ) + m2 ×g× (L2) - T(L)
so
2 ×9.8 × ( 1.4/2) + 5×9.8 × ( 0.8) - T(1.4) = 0
T = 52.98 / 1.4
T = 37.8
so tension is 37.8 N
Thinking about Planck's law, the Red star would give off the most orange light.
According to Planck's Law, distinct atoms and molecules can emit or take in power in discrete portions simplest. The smallest amount of strength that can be emitted or absorbed inside the form of electromagnetic radiation is called quantum.
Planck's Law describes the quantity of spectral radiance at a particular wavelength radiated through a black body in equilibrium. The equation is E=hv.
The floor temperature of a celeb determines the color of mild it emits. Blue stars are warmer than yellow stars, which are hotter than red stars. The bright orange celebrity Arcturus is particularly noteworthy for its massive right motion, The color is a characteristic of their floor temperatures.

Answer:
Ek = 1705.28 [J]
Explanation:
In order to solve this problem, we must remember that kinetic energy can be calculated by means of the following equation.
where:
m = mass [kg]
v = velocity [m/s]
Ek = kinetic energy [J] (Units of Joules)
