Answer:
0.75
Explanation:
Since the static frictional force is the maximum force applied just before sliding, our frictional force, F is 300 N.
Since F = μN where μ = coefficient of static friction and N = normal force = 400 N (which is the downward force applied against the surface).
So, μ = F/N
= 300 N/400 N
= 3/4
= 0.75
So, the coefficient of static friction μ = 0.75
Magnitude of acceleration
Explanation:
We know that acceleration can increase depending in the force applied on an object, any object with a greater mass will apply a greater force. F = M(a).
The only one with two different alleles is d meaning it is heterozygous
D
Answer:
Lenz's law
Explanation:
it states that induced emf of different polarities induces a current whose magnetic field opposes the change in magnetic flux through the coil in order to ensure that original flux is maintained through the coil when current flows in it.
according to Faraday' s law of electromagnetic induction
Where -ve sign due to lenz's law
Emf is the induced voltage also known as electromotive force
N is the number of loops.
dϕ Change in magnetic flux.
dt Change in time.
Red has the longer wavelength. Wavelength and frequency are inversely related, so the longer the wavelength, the lower the frequency. This lower frequency is them perceived by our eye as the color red.
