The change in distance is 30 because if you subtract both number you'll get 30
Answer:
- Here we use the conservation of momentum theorem.
- m stands for mass, and v stands for velocity. The numbers refer to the respective objects.
- m1v1 + m2v2 = m1vf1 + m2vf2
- Since the equation is perfectly inelastic, the final velocity of both masses is the same. Let’s account for this in our formula.
- m1v1 + m2v2 = vf(m1 + m2)
<u>Let’s substitute in our givens.</u>
(0.002 kg)(700 m/s) + (5 kg)(0 m/s) = vf(0.002 kg + 5 kg)
I assume you are proficient in algebra I, so I will not include the steps to simplify this equation.
Note that I have considered the bullet’s velocity to be in the positive direction,
The answer is vf = 0.280 m/s
Given what we know about volcanic formations, we can conclude that the Mt. St. Helens volcano was formed by the process described in option D, "Subduction an oceanic continental convergent boundary caused a mountain range to form and magma to come to the surface".
Mt. St. Helens is a volcano that falls under the category of a stratovolcano. Stratovolcanoes are volcanoes that commonly form at subduction zones. This process forms chains or clusters of mountains along the boundaries of tectonic plates, where oceanic crust is pulled under another type of crust. This process tends to form mountain ranges which contain volcanoes, such as:
- Cascade Range (To which Mt. St. Helens belongs)
- Los Andes
- Rocky Mountains
- Campania Mountain range
and so on.

Answer:
1.2 s
Explanation:
The period of a pendulum is the time it takes to complete one cycle, as in move and return to its initial state, for example going from one side to the other and coming back. If this pendulum goes from one side to the other in 0.6 s, it will take it the doble of that time to perform a cycle, and that is the period
T = 2 * 0.6 s = 1.2 s
Answer:

Explanation:
In a LC circuit The time constant τ is the time necessary for 60% of the total current (maximum current), pass through the inductor after a direct voltage source has been connected to it. The time constant can be calculated as follows:

Therefore, the time needed for the current to reach a fraction f = 0.6(60%) of its maximum value is:
