here we can say that since the hill is friction less So total energy is now conserved
we can use the energy conservation principle now
here we can say that initial KE is zero as the child and sled is at rest
and the final potential energy will also be zero as the child will reach the bottom
So here we can say
so final speed will be 12.8 m/s
-- Photographic film detects radiation.
-- Gas occupies the whole container.
-- The Geiger counter is used to detect and measure
the intensity of radiation.
-- An atom is the <span>smallest particle to retain characteristics
of the element.
-- The atomic mass is the mass of the protons and neutrons in the atom.</span>
(The electrons hardly make any difference. One proton or neutron has
as much mass as more than 1800 electrons.)
-- A solid has a fixed shape.
-- The neutron is electrically neutral. It has no charge.
-- The proton has a positive charge.
-- The electron has a negative charge.
-- The atomic number is the number of protons in the nucleus of an atom.
Answer:
D
Explanation:
Cells are the smallest unit of organizaiton, followed by tissues, organs, organ systems, and then organisms themselves.
It depends on the steady-state frequency. At zero frequency an inductor behaves like an open circuit. As the frequency increases, the inductor acts more like an open circuit and a capacitator acts more like a short circuit
The answer to your question is TWICE AS GREAT
