Scrat [10]3 years ago

Answer:

Okay

Explanation:

First we should quickly remind ourselves of the equation for density:density= mass/ volumeTo calculate the density we need a method of measuring the mass of each object and another method for measuring the volume of each object. To measure the mass in both cases we can simply use a measuring balance. To measure the volume we will need to use 2 separate methods. For the cube we can simply measure the length, height and depth with a ruler, multiply our measurements and we obtain the volume. The statue is a little more tricky because it has an irregular shape so we can't use the ruler anymore. Instead we should use graduated tank/trough of water. First of all measure the amount of water in the tank before putting in the statue. Then submerge the statue in the water and take another measurement of the volume of water in the tank. The statue will displace the water in the tank giving a higher value. We finally subtract the initial volume from the final volume and we should obtain the volume of the statue.We now have all the measurements necessary to calculate the density of both objects!

Consider a diffraction grating of width 5cm with slits of width 0.0001 cm separated by distance of 0.0002cm 1:what is the corres
sashaice [31]

Answer:

a) d= 0.0002cm

b) m=3

Explanation:

From the question we are told that:

Width of diffraction grating W_g= 5cm

Width of silt w_s 0.0001 cm

Distance d= 0.0002cm

a)

Generally the grafting element is the distance b/w  the silts

d= 0.0002cm

Therefore the grafting element is

d= 0.0002cm

b)

Generally the equation for diffraction state is mathematically given by

 dsin\theta=m\lambda

Since

 sin\theta \leq 1

Therefore

 m \leq \frac{d}{\lambda}

 m \leq \frac{0.0002}{0.000055}

 m \leq 3.6

Therefore orders observed with \lambda is

 m=3

A 0.380 kg block of wood rests on a horizontal frictionless surface and is attached to a spring (also horizontal) with a 28.0 N/
Sati [7]

Initial momentum of the Play-doh: 0.0600 x 2.60 = 0.156 kg/m/s

Total mass of the block and play-doh: 0.38 + 0.0600 = 0.44 kg.

Final momentum is mass x velocity = 0.44v

V = Initial momentum / mass

V = 0.156 / 0.44 = 0.3545 m/s

Work done by spring is equal to the Kinetic enrgy.

Work Done by spring = 1/2 *28.0 * distance^2 = 14 * d^2

KE = 1/2 * 0.44* 0.3545^2

set to equal each other:

14 * d^2 = 0.22 *0.12567

Solve for d:

d = √(0.22*0.12567)/14

d = 0.44 meters = 4.4cm
