A small plane can travel at 200km/h in still air. If a 50km/h wind is coming from the east, determine the ground velocity of the plane if the pilot keeps the plane pointed (N).
A hot-air balloon takes off from the ground traveling vertically with a constant upward acceleration of magni- tude g/4. After time interval At, a crew member releases a ballast sandbag from the basket attached to the balloon. How many seconds does it take the sandbag to reach the ground?
The time it takes for the sandbag to reach the ground would depend on the height from which it was released.
To find out how long it takes for the sandbag to reach the ground, we can use the equation of motion for a vertically falling object under the influence of gravity:
s = v0*t + (1/2)gt^2
where s is the distance fallen, v0 is the initial velocity (which is 0 m/s for the sandbag), t is the time elapsed, and g is the acceleration due to gravity (approximately 9.8 m/s^2).
We know that the sandbag is being released from the balloon and has an upward acceleration of g/4. So, the equation of motion becomes
s = v0t + (1/2)(g - g/4)*t^2
We also know that s is the distance fallen to the ground, which we can take as the final distance.
Now solving the equation for t
t = sqrt(2*s/(g-g/4))
It is given that the magnitude of the upward acceleration is g/4, so (g-g/4) = 3g/4, so the final equation becomes
t = sqrt(2*s/(3g/4))

The moving charge from point A to point B, the electric force that has done work is 2.08 J.
The work done by the electric force exchanges with the amount of charge transferred and exchanges with the potential difference between the starting and destination points.
To complete the task, we must find out the potentials at nodes A and B. Then we can calculate the electric potential energy of the charge Q 3 in these places. The work done by the electric force by moving the charge from A to B is equal to the difference in the electric potential energy.
To answer this question, we use the following formula:
W = Q3 (Q1-Q2)/4πε₀ (1/a - 1/b)
Numerical substitution:
Q3 = -3. 1 μC = -3.1 x 10⁻⁶C
Q1 = -5.6 μC = -5.6 x 10⁻⁶C
Q2 = 3.4 μC = 3.4 x 10⁻⁶C
a = 3 cm = 3 x 10⁻² m
b = 4 cm = 4 x 10⁻² m
ε₀ = 8.85 x 10 ⁻¹² C²N⁻¹m⁻² (from the table)
W = Q3 (Q1-Q2)/4πε₀ (1/a - 1/b)
W = -3.1 x 10⁻⁶C (-5.6 x 10⁻⁶C - 3.4 x 10⁻⁶C)/4π8.85 x 10 ⁻¹² (1/0.03 - 1/0.04)
W = -3.1 x 10⁻⁶C (-9 x10⁻⁶C)/4π8.85 x 10 ⁻¹² (1/0.03 - 1/0.04)
W = 27.9 x 10⁻¹² C/4π8.85 x 10⁻¹² (8,3)
W = 27.9 x 10⁻¹² C/111,25 x 10⁻¹² (8,3)
W = 0,25 x 8,3

The power of a hairdryer with a current of 4A and a resistance of 60Ω is 240W (watts).
What is resistance?Resistance is the opposition to the flow of electric current or the process of slowing down the flow of electric current. It occurs when electrons collide with atoms in a conductor, such as a wire. Resistance is measured in ohms and is determined by a material's electrical properties, like its cross-sectional area, length and type. Resistance can be used to control the amount of current in a circuit. It can also be used to convert electrical energy into thermal energy.
This is calculated by multiplying the current (4A) by the voltage (V = I x R, so V = 4A x 60Ω = 240V) and then multiplying the voltage by the current (240V x 4A = 240W).

Self-ignition would occur in the engine uing certain brand of petrol if the temperature due to

compreion i
Self-ignition, also known as pre-ignition, occurs in an internal combustion engine when the fuel-air mixture in the combustion chamber ignites before the spark plug fires.
One way to avoid pre-ignition is to limit the compression ratio of the engine, as a higher compression ratio can lead to higher temperatures in the combustion chamber.
The ideal gas law states that PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature.
The compression ratio of an engine is the ratio of the volume of the combustion chamber when the piston is at the bottom of its stroke (the "swept volume") to the volume of the combustion chamber when the piston is at the top of its stroke (the "clearance volume").
Given that the temperature at which self-ignition would occur using a certain brand of petrol is 350°C, and assuming that the ideal gas law applies, we can calculate the highest compression ratio that may be used to avoid pre-ignition.
To do this, we need to know the initial temperature and pressure in the combustion chamber, as well as the final temperature and pressure after compression. We can then use the ideal gas law to calculate the compression ratio.
In conclusion, based on the information provided, it is possible to calculate the highest compression ratio that may be used to avoid pre-ignition in an engine using the ideal gas law. However, more specific information such as the initial temperature and pressure and the specific brand of petrol is needed for a more accurate calculation.

to friction?
The kid's speed at the bottom of the slide is 8 m/s.
What is the kid's speed at the bottom of the slide?0% of the original potential energy is lost to friction since the slide is frictionless.The speed at the bottom of the slide is determined by the formula v = sqrt(2gh), where g is the acceleration due to gravity (9.81 m/s^2) and h is the height of the slide (4 m). Therefore, the speed at the bottom of the slide is 4.9 m/s.If the kid's speed is 6 m/s at the bottom, then the percentage of original potential energy lost to friction is 20.8%. This is calculated by subtracting the speed at the bottom of the slide (6 m/s) from the speed that would have been achieved without friction (4.9 m/s), then dividing the difference (1.1 m/s) by the speed without friction (4.9 m/s). This answer is then multiplied by 100 to get a percentage.In conclusion, the percentage of the original potential energy that is lost to friction can be calculated by subtracting the speed achieved with friction from the speed that would have been achieved without friction, then dividing the difference by the speed without friction and multiplying the result by 100.To learn more about potential energy refer to:

Explanation above
What is the weight of 50 kg object on Earth with 9. 8 m s2 gravitational field strength?.
The weight of the object of mass 50 kg on Earth is 490 N.
The amount of substance contained in a thing is defined as its mass. The kilogram is its SI unit (kg). The amount of force with which an object is attracted by the earth is defined as its weight. The SI unit of weight is Newton(N).
We have:
Mass of object (m)
m = 10 kg.
Gravitational acceleration on earth (g) = 9.8m/s²
Weight(W)= mg N
⇒ W = 50 kg × 9.8 m/s²
⇒ W = 490 N
Therefore, the weight of the object of mass 50 kg on earth is 490 N.
