Answers
Answer:
The gas, which is usually a hydrocarbon fuel, provides the energy. So when the fuel burns with oxygen in the air, it creates heat energy.
Explanation:
Therefore, chemical energy in carbon is released during the combustion process. Carbon dioxide is created, because the carbon-oxygen chemical bonds in the carbon dioxide form which releases heat.

A projectile is launched with an initial speed of 12 m/s. At its highest point its speed is 6 m/s. What was the launch angle of the projectile?
Answers
We want to find at what angle a projectile is launched given that at the highest point, the speed is 6m/s.
The launch angle of the projectile is 60°.
Remember that the only acceleration will appear on the vertical axis, and this is the gravitational acceleration, this means that on the horizontal axis we will have a constant speed.
Also remember that when an object is on its highest point, the vertical velocity is equal to zero, then it only has horizontal velocity (which we know it is a constant).
Then we can conclude that the horizontal velocity is equal to 6m/s.
If the angle is measured from the horizontal axis, we will have that the horizontal velocity is a projection on the x-axis of the initial speed, this is:
12m/s*cos(θ) = 6m/s
Now we can solve this for theta.
cos(θ) = (6m/s)/(12 m/s) = 1/2
θ = Acos(1/2) = 60°
The launch angle of the projectile is 60°.

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

felt under ground?
Answers
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.

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
Answers
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?
Answers
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
