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

Answer:
Nearly all frequencies and wavelengths of electromagnetic radiation can be used for spectroscopy. Radio waves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays are all types of electromagnetic radiation. Radio waves have the longest wavelength, and gamma rays have the shortest wavelength.

Answer:
<h3>The answer is 2.16 m/s²</h3>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
f is the force
m is the mass
From the question we have
We have the final answer as
<h3>2.16 m/s²</h3>
Hope this helps you
GPE is given by the formula mg∆h or mass x gravity x height
Gravity is a constant (9.81) so the total GPE is going to depend on the mass of the object and its height above the ground.
