Answer:

a = 18.19 [tex]m/s^{2}[/tex]

Explanation:

Given

Mass of the rocket m = 0.500 kg

upward force [tex]F_{up}[/tex] = 15 N

Air Resistance [tex]F_{Res}[/tex] = 1.00 N

Solution

Net force = Upward forces - downward forces

Net force = Upward force - (air resistance + weight)

[tex]F_{net} = x_{up} -(F_{Res} +mg )\\\\F_{net} = 15 -( 1 + 0.5 \times 9.81)\\\\F_{net} = 15 - (1+ 4.905)\\\\F_{net} = 9.095[/tex]

Net acceleration

[tex]a = \frac{F_{net} }{m} \\\\a = \frac{9.095 }{0.5}\\\\a = 18.19 m/s^{2}[/tex]

Final answer:

The length of the bridge is calculated by solving the equation derived from the sound travel times through air and steel, considering the 1.4 seconds delay. Upon calculation, the bridge length is found to be 476 meters.

Explanation:

To determine the length of the bridge given the time delay of sound arrival between steel and air, we need to establish two equations to represent the travel times of sound through both mediums. The first equation represents the time taken for sound to travel through the air ([tex]t_{air}[/tex]) and the second one for the time taken through steel ([tex]t_{steel}[/tex]). We know that sound travels faster in steel than air, so we can say:

[tex]t_{air}[/tex] = distance / speed in air = L / 340 m/s

[tex]t_{steel}[/tex] = distance / speed in steel = L / 5100 m/s

The delay between the two sounds was given as 1.4 seconds, so we can set up the following equation:

[tex]t_{air} - t_{steel}[/tex] = 1.4 s

(L / 340 m/s) - (L / 5100 m/s) = 1.4 s

Now, we solve for L (the length of the bridge), which results in:

L = 1.4 s / ((1/340 m/s) - (1/5100 m/s))

Upon calculation, L = 476 m

Therefore, the length of the bridge is 476 meters.

Final answer:

To determine the distance the water hits the ground from the sprinkler, projectile motion principles are applied, separating the initial velocity into horizontal and vertical components and then calculating the time of flight and horizontal distance.

Explanation:

A student asked how far water will hit the ground if a sprinkler sprays water at a velocity of 6.3 m/s, aimed 25 degrees above the ground, ignoring air resistance. To solve this, we use the principles of projectile motion. First, decompose the initial velocity into horizontal (vx) and vertical (vy) components. The horizontal velocity, vx = v × cos(θ) and the vertical velocity, vy = v × sin(θ), where θ is the launch angle and v is the initial velocity.

For a projectile landed on the same level from which it was launched, the time of flight, t, is given by t = 2 × vy / g, where g is the acceleration due to gravity (9.8 m/s2). The horizontal distance, or range, R, is then R = vx × t. Substituting the given values, vx = 6.3 × cos(25°) and vy = 6.3 × sin(25°), we can find t and subsequently R.

The table shows information about the moons of mars what is the orbital period of Deimos 1.26 days.

The amount of time a given astronomical object takes to complete one orbit around another object.

The table is missing, however I found the value of the orbital time period of Deimos on the web:

t = 30.4 hours

So, 30.4 hours. With a simple proportion we can convert it in days:

1 d: 24 h = x : 30.4 h

from which we find

x = 1.26 day

So, 1.26 days,

Answer:

A. People deserve what happens to them, whether good or bad.

Explanation:

The Just world hypothesis states that noble actions are rewarded and unjust actions are penalized. This hypothesis states that there is a force in the universe that restores the moral balance. This can be better understood by sayings like "what goes around comes around" and "you got what was coming to you".

So, bad people deserve something bad happening to them and good people also deserve what is happening to them.

The separation of the electromagnetic and weak nuclear forces from the unified electroweak force led to distinct electromagnetic and weak forces as the universe cooled, which contributed to the conditions necessary for the formation of nucleons.

After the electromagnetic and weak nuclear forces were separated from the unified electroweak force, the universe progressed towards the age of nucleons where leptons and hadrons, including protons and neutrons, were in thermal equilibrium. The electroweak force, which combined the electromagnetic and weak nuclear forces at very high temperatures and densities present in the early universe, broke into distinct forces as the universe cooled down. This occurred shortly after the strong nuclear force had already separated from the electroweak force. Importantly, the electric and magnetic forces, despite being different aspects of the single electromagnetic force, remain unified and do not separate under cooler conditions because they rely on each other.

Yeah it is 70.4 for the Ax one and 49.3 for the Ay.

The value of Ax, the x component of the velocity of the helicopter, is approximately 70.5 km/h.

The question asks to determine the horizontal component of the velocity (Ax) of a helicopter traveling at 86.0 km/h at an angle of 35° to the ground. To find Ax, we can use the cosine component of the given velocity because the cosine of an angle in a right triangle gives the adjacent side over the hypotenuse, which corresponds to the horizontal component over the total velocity.

To find the value of Ax, we can break down the velocity vector of the helicopter into its x and y components. The x component of the velocity can be found using the formula Vx = V * cos(angle), where V is the magnitude of the velocity and angle is the angle with respect to the ground.

In this case, V = 86.0 km/h and angle = 35°. Plugging in these values, we get Vx = 86.0 km/h * cos(35°) = 70.5 km/h.

So, the value of Ax is approximately 70.5 km/h.

Answer:

500 ft

Explanation: One must dim their high-beam lights when the oncoming vehicle is  500 ft away so that the oncoming driver can look clearly and drive safely. High beam light should be used at night to drive safely when one is not able to see ahead of the road clearly. Even for the most experienced drivers low visibility is an issue.

You should switch to low-beams when you come within 500 feet of an oncoming vehicle when driving at night to avoid blinding other drivers, equivalent to about 1.5 American football fields.

When driving at night, it is recommended to switch to low-beams whenever you come within 500 feet of an oncoming vehicle. This is important as it helps to prevent blinding the other driver with your vehicle's headlights, making the roads safer for everyone. To put the distance into perspective, 500 feet is approximately the length of 1.5 American football fields.

The spillage of the soup as you began moving is explained by inertia, where the soup wanted to stay in place while the bowl was moved, according to Newton's first law of motion.

When you moved with a bowl of hot soup and it spilled, the reason is related to the concepts of inertia and Newton's first law of motion. According to this law, an object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. In this case, the soup wanted to stay where it was, but you moved the bowl, causing a change in motion for the bowl and not the soup, resulting in the soup spilling. Air resistance is not a significant factor in this context as it primarily affects objects moving through the air and is related to how objects with different surface areas fall at different rates due to the force exerted opposite the motion.
