When it rains it starts to deteriorate the rocks causing erosion
Answer:
option (c)
Explanation:
The relation between the distance between the fringes is given by
where, D is the distance between the plane of slit and the screen
d is the width of slit, λ is the wavelength of light used.
As the slit made narrower, that means d decreases, the value of y increases, that means the fringes move farther.
Answer:
the dependent variable would be the growth of the plants
Explanation:
I know this because the independent variable is what changes which would be the amount of water and the dependent variable is what is being measured which is the growth of the plant
Answer:3m/s
Explanation:
mass(m)=50kg
Kinetic energy =225 joules
Kinetic energy=(m x (velocity)^2)/2
225=(50 x (velocity)^2)/2
Cross multiplying we get
225x2=50x(velocity)^2
450=50x(velocity)^2
Divide both sides by 50
450/50=(50x(velocity)^2)/50
9=(velocity)^2
Taking the square root of both sides we get
√9=velocity
3=velocity
Velocity=3m/s
