Terminal velocity is the velocity at which a falling body experience
when its weight is equal to the force resistance of force opposing the
fall.
At terminal velocity the acceleration of the body is zero,
which implies that the value of the this velocity is a uniform.
Answer:
0.75 NC⁻¹
Explanation:
Electric field intensity ( or strength of the electric field ) is the force per a 1 C charge,
So, Force (F) = Electric field intensity(E) × Charge (q)
F = E×q ⇒ q = F/E
= 4.5×10⁻⁴/6×10⁻⁴ = 0.75 NC⁻¹
According to cool om's law electric fields are generated due to charges. When charges are same there is a repulsive force acted on both charges. When charges are opposite there is a attraction force acted on both charges.
According to cool om's law,
F =G×q1×q2 / r²
F = force exerted of two charges
q1 , q2 = charges
r = distance between two charges
And also Electric field intensity is a vector which has a magnitude and direction both. Direction is depending on a charge and the sign of the charge
C
Unbalanced causes something to move because the net force is greater than zero
The blue color of the sky is the
result of scattering. The answer is letter B. it is specifically called the
Rayleigh scattering. This blue color is the result of the incoming rays of the Sun
into the earth’s atmosphere. It has he lowest wavelength which as we all see is
the blue spectrum of light.
Answer:
Drag or air resistance
Explanation:
The force of friction caused by a moving fluid is called drag. When that fluid is air, it's also known as air resistance.
