Physics
1 answer:
Veronika [31]4 years ago
4 0

Answer:

4.5 m/s

Explanation:

Initial momentum = final momentum

0 kg m/s = (15 kg) (3.0 m/s) + (10.0 kg) v

v = -4.5 m/s

The negative sign means it's moving in the opposite direction.

pantera1 [17]

Answer:

Δx = 4.68 x 10⁻³ m = 4.68 mm

Explanation:

The distance between the consecutive maxima, in Young's Double Slit Experiment is given bu the following formula:

Δx = λD/d

So, the distance between the eighth order maximum and the fourth order maximum on the screen will be given as:

Δx = 4λD/d

where,

Δx = distance between eighth order maximum and fourth order maximum=?

λ = wavelength = 487 nm = 4.87 x 10⁻⁷ m

d = slit separation = 0.2 mm = 2 x 10⁻⁴ m

D = Distance between slits and screen = 48 cm = 0.48 m

Therefore,

Δx = (4)(4.87 x 10⁻⁷ m)(0.48 m)/(2 x 10⁻⁴ m)

<u>Δx = 4.68 x 10⁻³ m = 4.68 mm</u>

A jet fighter flying at 300 m/s (just below the speed of sound) makes a turn of radius 1.85 km. (a) what is its centripetal acce
777dan777 [17]
centripetal acceleration can be determined using the following equation;
a = v² / r
a= centripetal acceleration
v = velocity 
r = radius
substituting the values in the equation,
a = (300 m/s)*(300m/s) / (1.85 *1000) m
   = 48.64 ms-²
