Answer:
a fossil of a footprint, trail, burrow, or other trace of an animal rather than of the animal itself.
Explanation:
Trace fossils are the indirect evidence of life in the past, such as the footprints, tracks, burrows, borings, and feces left behind by animals, rather than the preserved remains of the actual animal body itself.
Fossil is the naturally preserved remains of plants and animals which somehow get trapped in amber, hair, petrified wood, oil, coal, and DNA remnants.
Answer:
Explanation:
Physicists have found the latter- that matter is made of fundamental particles, the smallest things in the universe. Particles interact with each other according to a theory called the “Standard Model”. ... The electron is, as far as we know, one of the fundamental, indivisible building blocks of the universe
Scientists must have an unbiased type of investigation. These type of science requires three major characteristics for it to be functional and sticked to the truth: they must be impartial, accuarate and truthful. Without these characteristics there is no way forensic science must be treated as science.
Answer:
Explanation:
change in flux = no of turns x area of coil x change in magnetic field
= 163 x π 2.65² x 10⁻⁴ x ( .481 - 0 )
= 1728.84 x10⁻⁴ weber
rate of change of flux = change in flux / time
= 1728.84 x10⁻⁴ / .149
= 11603 x10⁻⁴ V .
volt induced = 1.16 V
current in the circuit
= volt induced / resistance
1.16 / 10.7 = .1084 A
energy dissipated = i²Rt where i is current , R is resistance and t is time.
= .1084² x 10.7 x .149
= .018734 J
= 18.73 mJ .
Answer;
=0.43 m/s²
Solution;
There will be the tension in the cable, T, upwards and the weight of the elevator, mg, downwards.
By Newton's second law, the sum of the forces will be equal to mass×acceleration.
Resultant force = m × a
Then T - mg = ma so the tension in the cable is
T = m(g+a)
The cable will break when T = 21,800 N
Solving for a, that happens when
a = 21800/2130 - g
= 10.23 - g (in m/s^2)
If you're using g = 9.8 m/s^2
Then the maximum acceleration allowed is 10.23-9.8 = 0.43 m/s^2
