Answer:
14,700 N
Explanation:
The hyppo is standing completely submerged on the bottom of the lake. Since it is still, it means that the net force acting on it is zero: so, the weight of the hyppo (W), pushing downward, is balanced by the upward normal force, N:
(1)
the weight of the hyppo is
where m is the hyppo's mass and g is the gravitational acceleration; therefore, solving eq.(1) for N, we find
Answer: The correct answer is "metalloid".
Explanation:
Metal is the material which can conduct electricity as it contains free electrons. It is good conductor of electricity. For example, copper, silver.
Metal can be drawn into wires. This property of material is called ductile.
Metal can be beaten into sheets. This property of material is called malleable.
Non metal is the material which cannot conduct electricity as it does not contain free electrons. They are poor conductor of electricity. For example, oxygen.
Metalloid: It has properties of both metals and non metal. It is electrical conductor. For example, semiconductor- silicon and germanium. But they cannot be pulled into wires.
Therefore, a material you are testing conducts electricity but cannot be pulled into wires. It is most likely a metalloid.
We know, P = F . ΔV
P = 185 * 2.39 = 442.15 watt
