Answer:
Ozone is a compound.
Explanation:
Elements are simple atoms that can merge or combine to produce a bigger molecule called a compound. They can not be splitted into smaller atoms. Examples are: hydrogen, carbon, etc.
A compound is formed as a result of the combination of two or more elements. They can be splitted into elements. Examples are: ammonium, water, carbon dioxide etc.
Ozone () is a less stable allotrope of oxygen which is made up of three atoms of oxygen. Therefore, it is a compound.
Answer:
by taking other atoms that have one shell and putting it i the spot that they need t in
Explanation:
First of all, what a weight is? weight is m × g.. and when a person is in space then the force of gravity isn't acting on him or her, so yeah it will not have weight, but remember gravity is a very very low, now if a body has more mass, more gravity will act on it right? just imagine the mass of a person and that of earth.. now yes, earth will do exert a force on the astronaut but is negiligable.
A robot is considered cyborg when half is human and half is robot.
Answer:
2.7 mV
Explanation:
A = 3.6 x 10^-3 m^2
B1 = 0.20 T, B2 = 1.4 T, t = 1.6 s
According to the Faraday's law of electromagnetic induction
e = - rate of change of magnetic flux
e = - dФ / dt
where, negative sign shows the direction of induced emf.
Ф = B x A
dФ / dt = A x dB / dt
e = A x dB / dt = 3.6 x 10^-3 x (1.4 - 0.2) / 1.6
e = 2.7 x 10^-3 V = 2.7 mV
