Answer:
Explanation:
If two forces act on an object in the same direction, the net force is equal to the sum of the two forces.
Group one on the periodic table, also known as the alkali metals, all:
- form ions with a charge of +1
- display similar extreme chemical behaviour
- have typical metallic properties
- are far too reactive to be found naturally in their pure forms
Answer:
a) 0.477 W/m²
b) 13.407 N/C
c) 18.96 N/C
Explanation:
P = Power = 150 W
r = Distance = 5 m
ε₀ = Permittivity of space = 8.854×10⁻¹² F/m
a) Average intensity

∴ Average intensity is 0.477 W/m²
b) Rms value

∴ Rms value of the electric field is 13.407 N/C
c) Peak value

∴ Peak value of the electric field is 18.96 N/C
Answer:
If there is a net force acting on an object, the object will have an acceleration and the object's velocity will change. ... Newton's second law states that for a particular force, the acceleration of an object is proportional to the net force and inversely proportional to the mass of the object.
