Explanation:
m1(v1) + m2(v2)
Opposite turns the plus to subtraction.
80(8) - 120(4.0)
60 - 480 = 160 kg m/s to the right
C. A mechanical wave generally travels faster in gases than liquids.
there’s no photo. brainly hasent been working for me today so not sure
Explanation:
it is energy that flows of electric charge it has the ability to do work or apply force to move an object.
Answer:
F=2627.6N
Explanation:
The work done by this resistive force while traveling a distance <em>d</em> underwater would be:

where the minus sign appears because the force is upwards and the displacement downwards.
This work is equal to the change of mechanical energy. At the diving plataform and underwater, when she stops moving, the woman has no kinetic energy, so all can be written in terms of her total change of gravitational potential energy:

Putting all together:
