a pilot flying low and slow drops a weight; it takes 2.4 s to hit the ground, during which it travels a horizontal distance of 200 m . now the pilot does a run at the same height but twice the speed. how much time does it take the weight to hit the ground?
(1) The time does pilot take the weight to hit the ground = 2.4 s
(2) The pilot travel before land = 400 m
Because fall time is proportional to fall height and acceleration due to gravity (g) is constant,
t₁ = t₂
s₁ = initial distance
s₂ = final distance
t₁ = initial time
t₂ = final time
Hence, the time does it take the weight to hit the ground = 2.4 s
The initial distance (s₁) = 200 m, and the pilot does a run at the same height but twice the speed.
So, the pilot travel before land:
s₂ = 2 x s₁

you have 2.97 amps traveling on the secondary ct circuit of a 2000:5 ct, what are the primary amps on the 69kv bus?
The primary amps on the 69kv bus would be 14.835 amps.
To determine the primary amps on the 69kv bus in this scenario, you would need to use the CT ratio of 2000:5. The CT ratio is used to convert the current on the secondary side of the CT to the current on the primary side. In this case, the secondary current is 2.97 amps, so you would multiply that by the ratio of 2000:5 (2000/5 = 400) to get the primary current.
2.97 amps x 400 = 14.835 amps.
Therefore the primary current on the 69kv bus is 14.835 amps.

We can find direction by electric field diagram and magnitude remain the same despite of a change in positions.
When a proton is placed at point A and an electron is placed at point B, the direction of the electric force F is determined by the electric field line diagram. The electric force between the two charges is a vector force, which means it has both a magnitude (strength) and a direction.
The magnitude of the electric force F between a proton and an electron is determined by Coulomb's Law, which states that the magnitude of the force between two charges is in direction proportion to charges' product and in inverse proportion with their distance squared.
to the product of the two charges and inversely proportional to the square of the distance between them. Thus, the magnitude of the electric force F between the charges is independent of the direction, so the magnitudes of the electric force F between a proton and an electron, regardless of their positions, will always be the same.
The direction of the electric force F, however, is determined by the electric field line diagram. In the diagram, the electric force F is directed away from the positive charge (the proton) and toward the negative charge (the electron). Therefore, the electric force F will be directed away from point A and toward point B, making the angle relative to the +x axis clockwise, with a positive angle.
In summary, the magnitude of the electric force F between a proton and an electron will remain the same regardless of the positions of the particles, while the direction of the electric force F will be determined by the electric field line diagram, with the angle relative to the +x axis clockwise, with a positive angle.

consider an automobile traveling at a constant speed along a road. determine the direction of the heat and work interactions, taking the following as the system: (a) the car radiator, (b) the car engine, (c) the car wheels, (d) the road, and (e) the air surrounding the car
We can determine the direction of heat and work interactions by understanding heat transfer for an automobile at constant speed.
The car radiator is an example of a heat source, with heat being transferred from the radiator to the engine, wheels, road, and air surrounding the car. It works as per laws of heat transfer.
The engine is an example of a work source, as work is done on the radiator and wheels, allowing the car to move.
The direction of heat and work interactions can be determined by considering the energy cycle of the car. Heat is transferred from the radiator to the engine, from the engine to the wheels, from the wheels to the road, and from the road to the air. Work is done from the engine to the wheels and radiator, and from the road to the wheels.
It is important to note that the heat and work interactions between the car radiator, engine, wheels, and air are not exclusive. In fact, as the car moves, heat is also transferred among all of these components. Heat is transferred from the engine to the wheels and the road, from the wheels to the road, and from the road to the air. Work is also done on the engine and wheels, as the car moves.
In conclusion, the direction of heat and work interactions between the car radiator, engine, wheels, road, and air surrounding the car can be determined by analyzing the energy cycle of the car. Heat is transferred from the radiator to the engine, from the engine to the wheels, from the wheels to the road, and from the road to the air. Work is done from the engine to the wheels and radiator, and from the road to the wheels. Heat and work are also transferred among all of the aforementioned components as the car moves.

Because the sun is exactly above the objects at midday and the sun rays drop vertically just on body, the shadow at noon is much shorter than shadows with in morning or the evening.
Explain the role of sun in forming shadows?To create a shadow, two things are required. Light is the first. The second is a light-obstructing object.
These two factors work together to create a space that really is darker than the surroundings. The shadow emerges behind you while the sun is directly in front of you. The shadow forms towards your right if the sun will be to your left. The shadow forms towards your left if the sun would be to your right.The size of such a shadow is influenced by the sun's position. Whenever the sun is lower in the sky, more light is blocked by a person or object. Shadows grow longer as more light is blocked.Whenever the sun is higher in the sky, less light is obstructed. As a result, shadows are shorter.

what property of a mineral indicates that it has cleavage?
Cleavage is the tendency of a mineral to break along smooth flat surfaces when struck. It is a property that reflects the crystal structure and is an indication of the mineral's internal atomic arrangement. A mineral with cleavage will break along specific planes, often yielding flat and smooth surfaces.
What type of minerals typically exhibit cleavage?Cleavage is a property of minerals that refers to the way they split or break along certain planes. Minerals that exhibit cleavage have a tendency to break along specific, smooth and flat surfaces. This property is caused by the internal arrangement of atoms in the mineral's crystal structure. Minerals that typically exhibit cleavage include micas, halite, calcite, fluorite, quartz, and feldspar. Minerals that exhibit good cleavage can be easily separated into thin sheets or plates, making them useful for a variety of industrial and commercial applications.

Cleavage is a property of a mineral that indicates its tendency to break along certain flat surfaces, rather than in a random pattern.
What do you mean by Cleavage?Bond cleavage, also known as bond fission, is the splitting of chemical bonds in chemistry. When a molecule is split into two or more pieces, this is commonly referred to as dissociation. According to how the bond is broken, there are generally two types of bond cleavage: homolytic and heterolytic.
In chemistry, cleavage essentially refers to the bond breaking. There are two types of cleavage: (1) An equal distribution of electrons between the two atoms causes a link between them to cleave. (2) In this form of connection, the most electronegative atom receives the bond's electron.
The presence of cleavage is an indicator of the arrangement of atoms in the crystal structure of the mineral, and the direction of the cleavage surfaces is determined by the crystal lattice. The term "cleavage" is often used interchangeably with the term "fracture," although fracture refers to any type of break in the mineral, regardless of whether it follows a specific pattern or not.
