Which contributions did Galileo make to the model of the solar system? Select two options.a mathematical model for the orbits of

According to the law of conservation of momentum, the total momentum before a collision equals the total momentum after the collision. When two carts collide and lock together, they form a single body with a certain mass and velocity. Based on the definition of momentum, we will compute the final velocity.

The equation U = Q + W defines the internal energy of the system, where U represents internal energy, Q corresponds to heat, and W is work done. You have an input of 2,380 J for work alongside 12,900 J of heat, which totals 15,280 J for internal energy.

Answer:

The canyon measures 50.176 meters deep.

Explanation:

The student drops a rock from the rim of the canyon, requiring us to ascertain the depth of the canyon—name how far the ground is below the cliff.

The data we have:

Time = t = 3.2 s

Initial velocity = = 0 m/s

Gravitational acceleration = g = 9.8 m/s²

Height = h =?

According to the second equation of motion

Given the initial velocity is zero, the right-hand side of the equation simplifies to zero

h = (0.5)(9.8)(3.2)²

h = 50.176 m

This calculation indicates that the rock dropped a distance of 50.176 meters to reach the canyon's base. Thus, the canyon depth is 50.176 meters.
