What can be seen in a crowd, in the ocean, and
felt under ground?
Answer: Convection currents in the molten mantle cause the plates to slowly move about the Earth a few centimeters each year. Many ocean floor features are a result of the interactions that occur at the edges of these plates.
Explanation:
The convection currents can be seen in a crowd, in the ocean, and can also be felt underground.
A convection current simply means the process that has to do with the movement of energy from one particular place to another.
A convention current is also known as convection heat transfer. Convention currents are due to differential heating. This brings about the circulation patterns that are referred to as convection currents that can be found in the atmosphere, water, and the mantle.

can you please explain this answer?
Answer:
Final velocity = 7.4m/s
Explanation:
Use the equation:
acceleration = (final velocity - initial velocity)/time
Rearrange to get:
final velocity = (acceleration * time) + initial velocity
Now just substitute with the values you already have:
Final velocity = (-9.8m/s^2 * 0.7s) + 0.5m/s
Final velocity = 7.36m/s
We are using 2 sig-figs, so:
Final Velocity = 7.4m/s

What happens when equal forces
are exerted in opposite directions
(the same amount of push and
pull)?
A. There is positive net force.
B. There is negative net force.
C. The net force is zero.
D. There is a small net force.
Answer:
B I'm Pretty Sure :DDD
Explanation:
Balanced Forces
In one of your situations in the last section, you pushed or pulled on an object from opposite directions but with the same force. You observed that the object did not move. When the forces on an object are equal and in opposite directions, the forces are balanced, and there is no change in motion.
Una bola de 60 Kg se hace descender por medio de un cable, con una aceleración hacia abajo de 4 m/s2 . ¿Cuál es la tensión en el cable?
Answer:
240 N
Explanation:
La fuerza de la tensión del cable es la masa por la aceleración (F=ma).
F = (60)(4) = 240 N
A soccer ball is kicked 8 m north. Then a teammate kicks it 6 m east into the goal. What is the soccer ball’s displacement from where it was first kicked?
10 m northeast
14 m northeast
100 m northeast
4 m southeast
Answer:
Displacement=10 meters
Explanation:
The displacement is the direct path from the first contact with the ball and the last spot it was seen in. The ball was kicked north 8 meters, meaning it was kicked vertically upward, and then it was kicked east 6 meters, or to the right. If we were to draw the displacement we would see that this is a right triangle. That means we can use the Pythagorean Theorem:
[tex]a^2+b^2=c^2\\8^2+6^2=c^2\\64+36=c^2\\c^2=100\\\sqrt{c} =\sqrt{100} \\c=10[/tex]
Boom.
The displacement is 10 m toward the northeast. The first option is correct.
The displacement is a vector quantity having both magnitude and direction. It is equal to the path length between the initial and final positions.
Given:
North displacement, y=8 m
East displacement, x= 6 m
The net displacement is calculated using Pythagoras' theorem as the displacements are perpendicular to each other.
The displacement is given by:
d=√(x²+y²)
d=√(8²+6²)
d=10 m
So, the displacement is 10 m.
Therefore, the displacement is 10 m toward the northeast. The first option is correct.

A 15 kg chunk of ice falls off the top of an iceberg. If the chunk of ice falls 8m to the surface of the water what is its velocity?
Answer:
When we can get the Kinetic energy from this formula KE= 1/2 M V^2and we can get the potential energy from this formula PE = M g H
we can set that the kinetic energy at the bottom of the fall equals the potential energy at the top so, KE = PE
1/2 MV^2 = M g H
1/2 V^2 = g H
when V is the velocity, g is an acceleration of gravitational force (9.8 m^2/s) and H is the height of the fall (8 m).
∴ v^2 = 2 * 9.8 * 8 = 156.8
∴ v= √156.8 = 12.5 m/s

Calculate the average force a 60.0-kg sprinter exerts backward on the track to accelerate from 2.00 to 8.00 m/s in a distance of 2.50m
Hi there!
Because of Newton's Third Law, the force exerted by the sprinter on the track is equal and opposite to the force exerted by the track on the sprinter.
We can begin by calculating the sprinter's acceleration. Use the equation:
vf² = vi² + 2ad
Rearrange for acceleration:
(vf² - vi²)/2d = a
Plug in values:
(8² - 2²)/2(2.5) = 60/5 = 12 m/s²
Calculate the force:
∑F = ma
∑F = 60 × 12 = 720 N. This is the amount of force exerted by the track on the sprinter in causing him to accelerate forward.
Thus, the backward force exerted by the sprinter on the track is the opposite, or -720 N.

In an electron cloud, an electron that is closer from the nucleus has?
Answer:
It should be less energy
Explanation:
The further away from the nucleus, the more it holds, correct? So those closer to the nucleus hold less electrons. So therefore, the ones that are closer must have more energy than the outer electrons.
