School, they drove 20 km in 10 min, what was the VELOCITY of the team?
0.5 km/min
0.5 km/min SOUTH
2 km/min
2 km/min SOUTh
Answer:
2km/min
Explanation:
Velocity= change in distance / time taken
Velocity = 20km/10min=2km/min south
South is placed there to show what direction she went, as velocity has both magnitude and direction

An archer uses 2000J of energy to pull a bow string 0.15m. What is the force constant (k) of the bow string?
The spring constant of the given bow spring is equal to 1.77 × 10⁵ N/m.
What is Hooke's law?Hooke's law can be described as a law that states that the force (F) required to extend or compress a spring by displacement linearly with respect to that displacement along a straight line.
The spring force can be represented in the form of an equation:
F = -kx
where k is a spring constant of the spring and x is the deformation of the spring. The negative sign shows that force is restoring force.
The energy that can be stored in the spring when it is stretched is given by:
E = (1/2)kx²
Given, the energy stored in the spring when it is stretched, E = 1000J
The distance by which the bow spring is stretched, x = 0.15 m
2000 = (1/2) × k (0.15)²
k = 1.77 × 10⁵ N/m

As a geologist, you come across a landscape with a massive fault zone that
produces a lot of large earthquakes but has no volcanoes. What type of plate
boundary is this? What are the movements of plates there? Where is this type
of boundary found in California?
Answer:
At a convergent boundary where both plates are continental, mountain ranges grow and earthquakes are common. At a transform boundary, there is a transform fault and massive earthquakes occur but there are no volcanoes. Processes acting over long periods of time create Earth's geographic features.

Which two statements describe what happens in both nuclear fusion and
nuclear fission reactions?
A. Each nucleus formed has fewer protons than the original nucleus
had.
B. Nuclei with small masses combine to form nuclei with larger
masses.
C. Radiation is released from the nuclei that undergo a reaction.
D. A small amount of the mass in each nucleus that undergoes a
reaction is converted to energy.
Answer:
C. Radiation is released from the nuclei that undergo a reaction.
D. A small amount of the mass in each nucleus that undergoes a
reaction is converted to energy.
Two statements, that describe what happens in both nuclear fusion and nuclear fission reactions, are:
Radiation is released from the nuclei that undergo a reaction.A small amount of the mass in each nucleus that undergoes a reaction is converted to energy.Hence, option (C) and (D) are correct.
What is nuclear reaction?A nuclear reaction is a process in nuclear physics and nuclear chemistry where two nuclei or a nucleus and an outside subatomic particle meet to create one or more new nuclides. Consequently, at least one nuclide must change throughout a nuclear reaction.
Instead of being referred to as a nuclear reaction, the process is simply referred to as a sort of nuclear scattering if a nucleus interacts with another nucleus or particle and they subsequently separate without altering the nature of any nuclide.

How can Newton’s law of action–reaction best be applied to explain the movement of a rocket?
Answer:As the fuel burns,gases push against the rocket, moving it upward
Explanation: here’s a tip download socratic take a pic of the question then scroll down there should be a quizzes with the answer for you quizzes is good when you want answers to a Science or language arts/reading so yea
Burning fuel in a rocket causes a push that propels the rocket forward from the front. The exhaust gas is pushed rearward in an equal and opposite direction as a result.
What is Newton’s law?The three fundamental laws of classical mechanics known as Newton's laws of motion describe how an object's motion and the forces acting on it interact.
The following is a paraphrasing of these laws: Unless a force acts upon a body, it remains at rest or in continual straight-line motion.
The creation of thrust by a rocket engine can be understood via Newton's third law. In a rocket engine, a fuel and an oxidizer are burned to produce hot exhaust gas.
The hot exhaust gas from the rocket accelerates to the back of the rocket after passing through the nozzle.
Thus, this way, Newton’s law of action–reaction best be applied to rocket movement.

Which magnets need electric current for magnetism?
a. Bar magnets b. Temporary magnets c. Permanent magnets magnets
Temporary magnets require electric current to produce magnetism and magnetic field lines B) Temporary magnets
In electromagnets, their magnetism is dependent on electricity with an iron core in the center. If we add an iron core to a solenoid, we can increase its magnetic field strength . When we connect a battery to a solenoid and wrap the sanded copper wire around a nail, a magnetic field is created. This force is generated by the magnetic field that's created when current flows through the coil.
As long as there is a direct current running through the coil, the nail will retain its magnetic properties. However, once the current stops, the magnetism of the nail is lost . Creating electromagnets can be achieved by winding wire around the iron core.
The advantages of electromagnets are :
Electromagnets can be turned on and off magnetic Fields can be increased and decreased Electromagnets can be cheap compared to permanent magnets. The same cannot be said for a permanent magnet.To learn more about Magnets

How do the particles in a Longitudinal Wave move?
A) Parallel to the direction of the wave
B) Perpendicular to the direction of the wave
C) Particles do not move
D) The particle is the wave (wave packet)
Explanation:
In a longitudinal wave the particle displacement is parallel to the direction of wave propagation. The particles do not move down the tube with the wave; they simply oscillate back and forth about their individual equilibrium positions. Pick a single particle and watch its motion.

Train A leaves the station heading north at 80 mph. At the same time and from the same station, Train B heads south 65 mph. How far apart are the trains after 3 hours fo travel?
Answer:
The trains will be 435 miles apart
Explanation:
Distance covered by the two trains can be obtained by multiplying their speeds with the time frame under consideration - in this our case, it is 3hours.
For Train A
Distance covered = 80mph X 3 hours = 240miles
For train B
Distance covered = 65mph X 3 hours = 195 miles.
The total distance between the two trains after 3 hours will be
240 + 195 = 435 miles
