meters did it fall
Answers
Answer:
50.2 meters
Explanation:
When an object falls, it goes a distance d in time t according to the formula:
\(d=\frac{1}{2}*g*t^{2}\)
d is the distance in meter, g is the acceleration due to gravity with the value of 9.8\(m/s^{2}\) , t is the time in seconds
Therefore, \(d = \frac{1}{2}*9.8*(3.2)^{2}\)
d= 50.176 ≈ 50.2m

Cool water comes to the surface off the coast of South America
Warm water produces rainy weather in Indonesia and Australia
Warm water spreads across the ocean and slows the trade winds
Answers
The normal result of the trade wind blowing from South America to Indonesia and Australia warm water produces rainy weather in Indonesia and Australia. Option D
What are trade winds?We know that the trade winds are the winds that tend to originate at the north east or the south eastern parts of the hemisphere and tend to be blowing across the seas towards the equator. Thus we can see that the focus of the trade winds is the equator and they emanate from north or south.
One of the effects of the trade winds is that they make the wind warmer and that would make to the emergence of a warmer weather and this would spread to the other parts of the word as we can see from map studies.
The effects of the trade winds blowing from South America would tend to be much more felt around the areas of Indonesia and Australia and this is very important to weather changes around those areas.

a synchronous motor draws 2000 kva at a power factor of 90% leading. calculate the approximate power developed by the motor [hp] knowing it has an efficiency of 95%.
Answers
The approximate power developed by the synchronous motor is 2293.14 hp.
To calculate the approximate power developed by the motor in horsepower (hp), we will follow these steps:
1. Find the real power (kW) using the formula: Real Power (kW) = Apparent Power (kVA) × Power Factor.
2. Convert the real power (kW) to mechanical power (kW) using the efficiency: Mechanical Power (kW) = Real Power (kW) × Efficiency.
3. Convert the mechanical power (kW) to horsepower (hp) using the conversion factor: 1 kW = 1.34102 hp.
Using the given information:
- Apparent Power = 2000 kVA
- Power Factor = 90% leading = 0.9
- Efficiency = 95% = 0.95
1. Real Power (kW) = 2000 kVA × 0.9 = 1800 kW
2. Mechanical Power (kW) = 1800 kW × 0.95 = 1710 kW
3. Approximate Power Developed (hp) = 1710 kW × 1.34102 = 2293.14 hp
In conclusion, the approximate power developed by the motor is 2293.14 hp.

Tom is throwing an baseball at an aluminum can,
present an argument about the likely kinetic energy of the ball before and after.
describe the evidence that would support the argument.
present an argument about the likely kinetic energy of the can before and after.
describe the evidence that would support the argument.
Answers
Answer:
The question relates to the conservation of energy principle, the conservation of the linear momentum, and Newton's Laws of motion
Part A
1) Tom throwing a baseball at a can
The initial velocity of the baseball = v₂
The initial kinetic energy of the baseball, K.E.₂ = (1/2)·m₂·v₂²
∴ The final kinetic energy of the baseball, K.E.₂' = (1/2)·m₂·v₂'² < (1/2)·m₂·v₂²
Therefore, the energy of the ball before the collision is lesser than the energy of the ball after the collision
2) The evidence that would likely support the claim is that the baseball's height above the ground reduces rapidly immediately after the collision which is due to the reduced velocity, and therefore, the reduced (kinetic) energy
The final velocity of the baseball v₂' < v₂
Part B
1) The argument
The initial velocity of the can = v₁ = 0 (The can is initially at rest)
The initial kinetic energy of the can, K.E.₁ = (1/2)·m₁·v₁² = 0
The final velocity of the can v₁' > v₁ = 0
∴ The final kinetic energy of the can, K.E.₁ = (1/2)·m₁·v₁² > 0
Given that the velocity of the can increases from zero to a positive value after collision with the baseball, the kinetic energy of the can is increased from zero before the collision to a positive value after the collision
2) An evidence in support of the argument is the motion of the can which was initially at rest which is an indication of increase in energy podded by the can

Answers
Main answer-
PE=mgh
KE=E-PE
V = (2*g*h)^½
at point A
PE = 10*9.8*50=4900 J
KE = 0 J ( because the velocity of the body is 0)
V=0
at point B
PE = 10*9.8*35=3430 J
KE = 4900-3430=1470 J
V= ( 2*9.8*15)^ ½
V=17.14 m/s
at point C
PE= 10*9.8*25=2450 J
KE=4900-2450=2450 J
V= (2*9.8*25)^ ½
V=22.135 m/s
at point D
PE=10*9.8*0=0 J
KE=4900-0=4900 J

The x-component of the vector is its magnitude along the x-axis.
Taking the coordinate of each vector:
Vector a = (1,4) : length of x- component = 1
Vector b = (1, 1) : length of x- component = 1
Vector c = (4, -4) : length of x- component = 4
Vector d = (-3, 4) : length of x- component = - 3

C. An addition of 200 J of kinetic energy and a loss of 250 J of
thermal energy
D. An addition of 300 J of thermal energy and a loss of 450 J of

Answers
Answer:
Correct option is (a)
Explanation:
According to conservation of energy: Total energy of system remains conserved or we can say total energy = constant
(a) 400J of GPE is added and 250J of thermal energy is lost
⇒ Total energy = 400-250 J = 150 J
hence, 150J energy is increased
(b) 100J of thermal energy is added and 450J of kinetic energy is lost
⇒ Total energy = 100-450 J = -350 J
hence, 350J energy is decreased or lost by system
(c)200J of kinetic energy is added and 250J of thermal energy is lost
⇒ Total energy = 200-250 J = -50 J
hence, 50J energy is decreased or lost by system
(d)300J of thermal energy is added and 450J of kinetic energy is lost
⇒ Total energy = 300-450 J = -150 J
hence, 150J energy is decreased or lost by system
Therefore, correct option is (a)

Tundra is distinct from an ice-sheet climate because it has at least one month above freezing on average. True Or False
Answers
True ,The Tundra climate is characterized by very low temperatures and short growing seasons.
It is found in regions with long, cold winters and short summers. However, it differs from an ice-sheet climate because it experiences at least one month with an average temperature above freezing. This allows for some vegetation to grow and for some animal life to thrive.
In contrast, an ice-sheet climate is characterized by year-round freezing temperatures and little to no vegetation or animal life.
Tundra is distinct from an ice-sheet climate because it has at least one month with average temperatures above freezing, which allows for the growth of some vegetation, such as mosses and lichens. Ice-sheet climates, on the other hand, have consistently freezing temperatures and are typically characterized by large expanses of ice and limited vegetation.

Which circuit element will have the greatest voltage drop 12V R1=10 R2=20 R3=30
Answers
The circuit element with the greatest voltage drop is R3 (resistor 3).
To determine the voltage drop across each resistor, we can use Ohm's Law, which states that V = IR, where V is voltage, I is current, and R is resistance.
First, we can find the total resistance of the circuit by adding the resistances of all three resistors:
R_total = R1 + R2 + R3
R_total = 10 + 20 + 30
R_total = 60 ohms
Next, we can find the total current flowing through the circuit by using Ohm's Law again, but this time solving for I:
I = V / R_total
I = 12 / 60
I = 0.2 amps
Now, we can find the voltage drop across each resistor by multiplying its resistance by the total current:
V_R1 = R1 * I
V_R1 = 10 * 0.2
V_R1 = 2 volts
V_R2 = R2 * I
V_R2 = 20 * 0.2
V_R2 = 4 volts
V_R3 = R3 * I
V_R3 = 30 * 0.2
V_R3 = 6 volts
Therefore, the circuit element with the greatest voltage drop is R3 (resistor 3), which has a voltage drop of 6 volts.
The voltage drop across each resistor in a circuit is proportional to its resistance. In this circuit, R3 has the greatest resistance and therefore has the greatest voltage drop.
