The answer would be C. velocity. When white light enters a prism it is refracted. This refraction is caused due to a change in velocity (generally speaking, velocity is considered speed in some cases) when entering the prism. In other words, when light enters a prism at an angle, the glass slows down the light causing the light to split into different colors.
Answer:
Explanation:
Density = mass/volume
132g/(48.9 cm³) = 2.7 g/cm³
(27 g)/(3 cm³) = 9 g/cm³
512 g/(65 cm³) = 7.9 g/cm³
1.2 kg/(3243 cm³) cm³ = 1200 g/(3243 cm³) = 0.37 g/cm³
Answer:
a) 2457J
b) 558W
c) 337N
Explanation:
Assuming dogs started from rest.
and the displacement is given by:
Using the energy conservation formula:
Because the motion started from rest the initial kinetic energy is zero, the motion occurred in-ground level so the gravitational energy is zero too.
the work done by the friction force is given by:
so:
The power is given by:
and the force exerted by the dogs:
It looks like a refractor.
The problem ask to calculate the bullet's flight time and the bullet's speed as it left the barrel. So base on the problem, the answer would be that the flight time is 0.076 seconds and the speed of the bullet is 657.9 m/s. I hope you are satisfied with my answer and feel free to ask for more if you have questions and further clarifications.
