Answer:
Coefficient of friction is the ratio of friction force to normal force.
μ = F/N
Answer:
Increase in strength of hurricanes
Explanation:
Answer:
speed and temperature
Explanation:
Two major factors, mass and distance, affect the strength of gravitational force on an object. You witness the first factor in everyday life - more massive objects are heavier weight the force with which an object near the Earth or another celestial body is attracted toward the center of the body by gravity. An object's weight depends on its mass (the amount of matter it consists of) and the strength of the gravitational pull.
Answer:
the separation of the interference maxima is directly proportional to the wavelength
the greatest separation must be obtained for the red light of
λ = 700
Explanation:
The double slit interference experiment is explained for the constructive interference case by the expression
d sin θ = m λ
where d is the separation between the slits, θ at the angle of separation of the different maxima, λ the wavelength and m the order of interference.
In these experiments the angles are always very small, so if the observation screen is at a large distance and y is the distance between the maximums, we can use trigonometry
tan θ = y / L
as the angle is small we can also use
tan θ = sin θ / cos θ = sin θ
when substituting we find
sin θ = y / L
the contributory interference equation remains
d y / L = m λ
y = m (L / d) λ
the quantity in parentheses is constant, so the variation in the separation of the interference maxima is directly proportional to the wavelength
by which the greatest separation must be obtained for the red light of
λ = 700
Answer:
The answer is 9.4 m/s
Explanation:
Because you add 5.0 + 4.5= 9.4
