A stationary observer observes a spaceship fly by. As the spaceship's velocity gets closer to the speed of light, the stationary observer would see the spaceship as being “blue-shifted” on the visible light spectrum.
This would also lead to the feeling of a faster time on the clock.
What is the Speed of Light?
This refers to the speed in which light waves propagate through different materials.
Hence, we can see that based on the fact that the observer is stationary and is observing a spaceship that is in outer space get to the speed of light, the stationary observer would see the spaceship as being “blue-shifted” on the visible light spectrum.
This is because the observer would come to the conclusions that the
Earth would appear blue-shifted its clocks would be moving more quickly than expected.

a) 4.8 m/s² his average acceleration during the first 2.5 s
b) 15 m distance he cover during the first 2.5 seconds.
c) 31 m/s his speed as he finished the race.
(a) How to calculate the Average Acceleration ?Average acceleration is calculated by using Newtons first law of motion
v = u + at
where
u is initial velocity
v is final velocity
a is constant acceleration
t is time
Given u = 0m/s , v = 12 m/s and t = 2.5 sec
Therefore average acceleration is given by
[tex]a=\frac{v}{t}[/tex]
[tex]a=\frac{12}{2.5}[/tex]
a = 4.8 m/sec²
b) Here we will use newtons second law of motion
[tex]s=ut+\frac{1}{2}at^{2}[/tex]

this is because the gravitational force acting on an object on earth is greater than the gravitational force acting on an object and the Moon .

Which has more total enthalpy 3kg of 20% of salt brine at 65 degrees Celsius or 5kg of 20% salt brine at 50 Degrees celsius, assuming 0 enthalpy at 0 degrees celsius? The specific heat capacity of 20% salt brine is 3.56kJ/kg*C
The 3kg of 20% of salt brine at 65 degrees Celsius has more enthalpy than the 5kg of 20% salt brine at 50 Degrees Celsius.
What is enthalpy?Enthalpy is defined as the total heat content of a system. The enthalpy is a measure of the total work which the system can do plus the internal energy of the system.
The enthalpy of the given solutions can be calculated as follows:
Enthalpy = mass * specific heat capacity * temperature change.For the 3kg of 20% of salt brine at 65 degrees;
mass of salt = 3 * 20% = 0.6 kg
specific heat capacity = 3.56kJ/kg*C
temperature change = 65°C
Enthalpy = 0.6 * 3.56 * 65
Enthalpy = 232 kJ
For the 5kg of 20% salt brine at 50 Degrees Celsius;
mass of salt = 5 * 20% = 1 kg
specific heat capacity = 3.56kJ/kg*C
temperature change = 50°C
Enthalpy = 1 * 3.56 * 50
Enthalpy = 178 kJ
Therefore, the 3kg of 20% of salt brine at 65 degrees Celsius has more enthalpy.

Calculation:Force acting on the car will be
ma = -mg sinθ
where,
m = mass of the car
a = acceleration of the car
g = acceleration due to gravity
θ = angle of inclination
Given,
θ = 10°
Put the values in the above equation,
ma = -mg sinθ

A runner exerts 2,000 j of work while traveling 10 m along a horizontal stretch of track. what average force was exerted by the runner?
The average force exerted by the runner is 200N.
A force is an influence that has the power to alter an object's motion. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.
When a force is exerted across a distance to an item, work is accomplished. This implies that the total energy of an object will be impacted when a force is applied to it over a distance.
Work = Force x Distance
Force = work / distance
Force = 2000 J / 10 m

The current through the 10 Ω resistor is 0.586A which is connected with a resistor in series combination.
Voltage divides in a Series combination and current divides in a parallel combination.
Let the three resistors joined in parallel be R₁, R₂, R₃
where, R₁= 4 Ω
R₂ = 6 Ω
R₃ = 10 Ω
Given, a battery of 12V and a 2Ω resistor say r is series with the parallel combination.
Equivalent resistance(R) in parallel combination is:
1/R = 1/R₁ + 1/R₂ + 1/R₃
1/R = 1/4 + 1/6 + 1/10
On solving, R = 1.9 Ω
Now, the Equivalent resistance(R) of parallel combination is in series with r = 2Ω
Let Equivalent resistance of Series combination be R'
R' = R + r
R' = 1.9 + 2 Ω
R' = 3.9 Ω
Now let's calculate the voltage drop in the resistor r = 2Ω
v = i × r where, i is the current in r and v is the voltage drop across r
v = 3.07 × 2
v = 6.14V
Voltage drop, V' across the Equivalent resistance(R) in parallel combination = Total voltage - voltage drop in the resistor r
V' = 12 - 6.14 V
V' = 5.86V
Now, the Voltage drop, V' across the Equivalent resistance(R) in parallel combination is same for all the three resistors R₁, R₂, R₃
So, Voltage is same in a parallel combination.

Direction angle of a vectorA vector's direction angle is the angle formed by the positive x-axis and the vector v. The arctangent of the ratio between the vertical and horizontal components of the vector, v=ai+bj, can be used to determine the direction angle,, of the vector.
What is the formula for direction?Use the formula = arctan(y/x) to determine the direction of the vector v = (x, y), where is the smallest angle the vector makes with the horizontal axis and x and y are its component vectors.
Does an angle have a direction?The angle a vector creates with a horizontal line is used to determine the vector's direction. The formula:where x is the horizontal change and y is the vertical change, gives the direction angle of a vector.

If the signal light changes from green to yellow as you enter the intersection, you should:_______
When the light turns from green to yellow while you are already in the intersection, proceed through the intersection at a safe speed.
To find the answer, we have to study more about the importance of traffic signals.
What are the importance of yellow signal light in traffic?Recognize that you have the right-of-way when a yellow light is flashing. Reduce your speed as you get close to a flashing yellow light and keep an eye out for other cars that might not be paying attention to or respecting your right-of-way. You should safely stop your car at any intersection where there is a constant yellow light. When the light turns from green to yellow while you are already in the intersection, proceed through the intersection at a safe speed.Thus, we can conclude that, When the light turns from green to yellow while you are already in the intersection, proceed through the intersection at a safe speed.

If the resistance in a circuit connected to a constant current is halved, how is the voltage in the circuit affected?.
The voltage is reduced by a factor of 2.
What is resistance?
Resistance is a proportion of the opposition to flow stream in an electrical circuit. Opposition is estimated in ohms, represented by the Greek letter omega (Ω). Ohms are named after Georg Simon Ohm (1784-1854), a German physicist who concentrated on the connection between voltage, current and resistance.The equation to compute the obstruction utilizing Ohm's Law is given as keeps:R = V I.
where,
R is the resistance of the resistor R in ohms (Ω)
V is the voltage drop in the resistor in volts.

What is the reactance of a 9. 0×10−2 μf capacitor connected to a 23 kv (rms), 550 hz line?
The Capacitive reactance of the capacitor is 3.22kΩ.
To find the answer, we have to study about the Capacitive reactance.
How to find the Capacitive reactance?It is given that,[tex]C=9*10^{-8}F\\f=550Hz\\[/tex]
Thus, the expression for capacitive reactance will be,[tex]X_c=\frac{1}{2\pi fC}[/tex]
By substituting values, we get,[tex]X_c=\frac{1}{2\pi *550*9*10^{-8}} \\\\X_c=3.22*10^3Ohm.[/tex]
Thus, we can conclude that, the Capacitive reactance of the capacitor is 3.22kΩ.
