Answer:

v = 10 [m/s]

Explanation:

The largest mass is that of 4 [kg], in this way the momentum can be calculated by means of the product of the mass by velocity.

P=m*v\\

where:

P = momentum [kg*m/s]

m = mass = 4 [kg]

v = velocity = 5 [m/s]

Now the momentum:

P=4*5\\P=20[kg*m/s]

This same momentum is equal for the other mass, in this way we can find the velocity.

P=m*v\\20=2*v\\v=10[m/s]

Standard weight and scales in the market should be checked in every two year why?​
disa [49]

Answer:

to check for errors.

Explanation:

since some of the components of the scale are metallic, they are prone to rusting which would cause error in reading of the scale so there is organized checking if the scale to correct that.

hope it helps .

A soap bubble appears red (λ = 633nm) at the point on its front surface nearest to the viewer. Assuming n = 1.35, what is the sm
alexira [117]

Answer:

The smallest film thickness is 117 nm.

Explanation:

Light interference on thin films can be constructive or destructive. Constructive interference is dependent on the film thickness and the refractive index of the medium.

For the first interference (surface nearest to viewer), the minimum thickness can be expressed as:

2t_{min} = \frac{wavelenth}{2n}

where n is the refractive index of the bubble film.

Therefore,

2t_{min} = \frac{633x10^{-9} }{(2)(1.35)}

2t_{min} =2.344x10^{-7}

∴ t_{min} =\frac{2.344x10^{-7} }{2}

t_{min} = 1.17x10^{-7} m = 117 nm.
