Velocity can be described as the same thing as speed but with _________________ included
Answers
Answer:
Direction
Explanation: Hope this helps!
Answer:
nvm its direction :))
Explanation:
Speed and velocity both represent a way to measure the change in position of an object relative to time. In fact, for a straight line motion, the speed and velocity of an object are the same (since distance and displacement will be the same). Speed and velocity are measured in the same units: meters per second or m/s.
Velocity is a measure of both speed and direction of motion. Velocity is a vector, which is a measurement that includes both size and direction. Velocity can be represented by an arrow, with the length of the arrow representing speed and the way the arrow points representing direction.

What is elastic collision?The collision in which the object bounces off after the collision is called the elastic collision. The one condition is given in the question that after the collision the running back bounces back and the linebacker stops
A linebacker runs at 3 m/s and collides with a running back running toward him at 3.2m/s. If the running back bounces back and the linebacker stops it means that the collision is elastic. And all the momentum is transferred to the other person.
Therefore the answer will be an option C. The momentum would be eliminated for the running back.

Particle A and particle B are held together with a compressed spring between them. When they are released, the spring pushes them apart, and they then fly off in opposite directions, free of the spring. The mass of A is 5.00 times the mass of B, and the energy stored in the spring was 46 J. Assume that the spring has negligible mass and that all its stored energy is transferred to the particles. Once that transfer is complete, what are the kinetic energies of each particle?
Answers
Answer:
Particle A: K.E = 38.3 J
Particle B: K.E = 7.67 J
Explanation:
Given that Particle A and particle B are held together with a compressed spring between them. When they are released, the spring pushes them apart, and they then fly off in opposite directions, free of the spring. The mass of A is 5.00 times the mass of B, and the energy stored in the spring was 46 J. Assume that the spring has negligible mass and that all its stored energy is transferred to the particles. Once that transfer is complete, what are the kinetic energies of each particle?
The total kinetic energy of Particle A and particle B should be equal to 46 J
Since the mass of A is 5.00 times the mass of B, then, the K.E energy of each particle can be calculated by using ratio.
5 + 1 = 6
K.E for particle A
5 /6 × 46 = 230 / 6 = 38.3 J
K.E for particle B
1/6 × 46 = 46 / 6 = 7.67 J

How are faults that occur in the middle of tectonic plates different from plate boundaries?
Answers
Divergent boundaries – where two plates are moving apart.
Transform boundaries – where plates slide passed each other.
:)
Causes of Earthquake
An earthquake is caused by a sudden slip on a fault. The tectonic plates are always slowly moving, but they get stuck at their edges due to friction.
Five causes of earthquake?
1. Volcanic Eruptions. The main cause of the earthquake is volcanic eruptions.
2. Tectonic Movements. The surface of the earth consists of some plates, comprising of the upper mantle
3. Geological Faults
4. Groundwater extraction – decrease in pore pressure.
5. Groundwater – increase in pore pressure.
6. Heavy rain.
7. Pore fluid flow.
8. High CO2 pressure.
9. Building dams.
Explanation:
Now, Boundaries between tectonic plates are made up of faults. which are associated with the various types of fault, normal, reverse and strike-slip faults
More so, Plate boundaries are always faults, but not all faults are plate boundaries.
