Answer:
A. Atoms are the smallest unit of an element.
Explanation:
The correct statement from the given choices is that atoms are the smallest unit of an element.
Atoms are the smallest particles that takes part in chemical reactions and they are made up of protons, neutrons and electrons.
- Elements are distinct substances that cannot be split up into simpler substances.
- They are made up of only one kind of atoms.
- Elements are not changed into atoms by chemical reactions.
- In chemical reactions, atoms simply recombine.
Answer:
False
Explanation:
Pascal is a pressure of one newton per square metre, or, in SI base units, one kilogram per metre per second squared.
Pa = N/m^2
Answer:
−1.9 × 10−5 Wb
Explanation:
Magnetic flux is the product of average magnetic field times the perpendicular area that is crosses times the angle between planar area and magnetic flux
Finding the area
Area = πr² = 3.14*0.075*0.075
Area=0.01767 m²
Magnetic flux = 0.01767*0.00110*cos 0
Magnetic flux =0.000019 = −1.9 × 10−5 Wb
Answer:4. Two charged objects have a repulsive force of 0.080 N. If the distance separating the objects is tripled, then what is the new force? Explanation: The electrostatic force is inversely related to the square of the separation distance.
