Answer:
Gamma rays
Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies.
we know 1kg=9.8N so 30 kg= 30 x 9.8 = 294 N
work is done when a 30 kg mass is to be lifted through a height 6m :
A = 294 x 6 = 1764 J
ok done. Thank to me :>
A pinhole camera<span> is a simple </span>camera<span> without a lens but with a tiny aperture, a</span>pinhole<span> – effectively a light-proof box with a small hole in one side. Light from a scene passes through the aperture and projects an inverted image on the opposite side of the box, which is known as the </span>camera<span> obscura effect.</span>
The conduction velocity of an axon is determined by myelin sheath
thickness and internode distance.
Axon are structures in the neuron which is involved in the conduction of
impulses away from the cell body. Axons which have myelin sheath conduct
impulses faster than those without it.
Axons which have thicker myelin sheath and longer internode distance will
increase the conduction velocity of an axon and vice versa.
