<span>Our equation 1 would be
m*v=M*V1+m*V2
v=V1+V2
v-V1=V2
the equation 2 would look like this
</span>V^2=V1^2+V2^2
V^2-V1^2=V2^2
(V-V1)*(V+V1)=V2^2Dividing with the 1
V+V1=V2
Answer:
Real image
Explanation:
The picture is real, but it is reversed and tiny. An picture generated by a pinhole camera has certain features. As compared item, the image created by a pinhole camera is normally pretty small and looks reversed both on the vertically and horizontally axis.
Acceleration is the ratio of a change in velocity to the time over which the change happend
Answer:
Explanation:
Thomas Young (1773 − 1829) first introduced the word “energy” to the field of physics in 1800, but the word did not gain popularity. Thomas Young later established the wave nature of light through interference experiments.
Weight is the force of gravity acting on a body. By newton's second law, that force can be calculated as W=mg, where g is the acceleration of gravity, 9.81 m/s^2. So, for the intrepid climber, this would be approximately 88.6 x 10 Newtons or about 886 Newtons.
