According to Newton's third law of motion, for every action, there is an equal and opposite reaction.

According to Newton's third law of motion, for every action, there is an equal and opposite reaction.

If a birthday candle is pushing down on a cake with a force of 0.02N, there must be an equal and opposite force acting on the candle. In this case, the cake exerts an upward force of 0.02N on the candle.

The cake's force is a reaction to the candle's downward force, and it balances out the candle's force, resulting in a net force of zero.

This means that the candle and the cake are in a state of equilibrium.

The two forces, one downward and one upward, occur simultaneously and are of equal magnitude but act in opposite directions, fulfilling Newton's third law of motion.

First, let's calculate the rocket velocity when it stops accelerating, using Torricelli's equation:

After the engine stops, the total acceleration will be the gravity acceleration, with a downwards direction and magnitude of 9.81 m/s².

The maximum height occurs when the velocity is zero, so we can use the formula below:

Now we need to calculate the time spent accelerating (engine turned on):

Therefore the total time, since lift-off until maximum height, is:

The rocket reaches the maximum height 11.12 seconds after lift-off.

They are not touching. Friction is a force that is created when two surfaces rub against each other. If two objects are not touching, then no force of friction can exist between them.

Friction is a force that occurs when two objects move or try to move across each other's surfaces. It is the resistance between two objects when they rub against each other. Friction is a type of force that opposes the movement of one object over another. It acts in a direction opposite to the direction of motion, and it can slow down, stop, or even reverse the motion of an object. Friction is caused by the interlocking of microscopic irregularities on the surfaces of two objects. In order for two surfaces to interact, they must be in contact with each other and have enough force to cause the microscopic irregularities to interact. The greater the force, the more friction is generated. Friction helps us to walk, run, and perform everyday activities. Without it, we would slip and slide on any surface.

The energy produced by a 200 W light bulb after 2.5 hours of use is 1,800,000 J.

Energy (J) = Power (W) x Time is the formula for computing energy from power and time (s). Power is the rate of energy production or consumption, commonly expressed in watts (W), and time is the length of time.

The following formula can be used to determine how much energy a 200 W light bulb produces over the course of 2.5 hours:

Energy (J) equals Power (W) times Time (s)

We must first translate 2.5 hours into seconds:

2.5 hours equals 9,000 seconds (2.5 × 60 x 60).

We can now determine how much energy the lightbulb produces:

= 200 W x 9,000 seconds.

If the Earth were modelled as a spinning vertical cylinder, the temperature distribution would show a pattern of lowering temperatures from the sides (equator) to the top and bottom (poles).

If the Earth were modeled as a vertical cylinder rotating on its axis, we can expect a general distribution of heat that varies with different regions of the cylinder, including the sides, top, and bottom. Here's a description of the possible temperature distribution:

   The sides of the cylinder, representing the Earth's equatorial regions, would generally experience higher temperatures due to their proximity to the Sun. These regions would be characterized by hot or warm temperatures, as they receive more direct sunlight and experience longer durations of daylight.

   The top region of the cylinder, corresponding to the Earth's North Pole or South Pole, would experience cold temperatures. These areas receive oblique sunlight, leading to lower solar radiation and shorter daylight periods. As a result, the temperatures would generally be cold, with icy conditions prevailing.

   The bottom region of the cylinder, corresponding to the opposite pole from the top, would exhibit similar characteristics to the top region. It would also experience cold temperatures due to the oblique sunlight and shorter daylight periods.

Overall, the temperature distribution on the Earth modeled as a rotating vertical cylinder would follow a pattern of decreasing temperatures from the sides (equator) to the top and bottom (poles).

This distribution is influenced by the varying angles at which sunlight reaches different latitudes, leading to variations in solar radiation and daylight duration.

The tail shape of a surfboard greatly affected the board's interaction with the wave's face and the flowing of water flowing.

The tail shape of a surfboard affects how the board depends on the wave's face, and the water flowing between it. More comprehensive, thicker tail shapes have more surface area and assist the board to float and create lift - allowing the surfboard to plane over the surface of the water more efficiently.

The shape of both the surfboard and its fin swap the way the water moves around it if you can grab a wave as well as the turning ability of the surfboard.
