It would be aluminum chlorite.
Answer:
8000 N
Explanation:
Applying
P = F×V.............. Equation 1
Where P = Power of the sport car, F = resistive force acting on the sport car, V = Speed of the sport car.
make F the subject of the equation
F = P/V............ Equation 2
From the question,
Given: P = 200 kW = 200000 W, V = 25 m/s
Substitute these values into equation 2
F = 200000/25
F = 8000 N
Answer:
2.08 s
Explanation:
We are given that
Speed,v=50mph=73.3ft/s
1 mile=5280 feet
1 hour=3600 s
Distance,d=461 ft
t=2.5 s
v'=60 mph=88 ft/s
We have to find the perception reaction time.
Perception reaction distance=
Answer:
Angle of incidence ray
Explanation:
The way light reflects off a smooth surface is described by the law of reflection. This law states that the angle of reflection equals the ANGLE OF INCIDENCE RAY.
This is because, when light is reflected off a smooth surface, the light is reflected by all the points that is present on that smooth surface.
Therefore the speed at which the light rays falls on the smooth surface is the same as the speed at which the light ray is reflected back. Due to their speed been the same, the distance of the incidence ray would also be the same as the distance of the reflected ray.
Hence the angle of incidence = angle of reflection.
The voltage as a function of time for the power source oscillating at the given frequency is determined as V = 169.7sin(120πt).
<h3>
Peak voltage</h3>
The peak voltage of the source is calculated as follows;
Vrms = 0.7071V₀
120 = 0.7071V₀
V₀ = 120/0.7071
V₀ = 169.7 V
<h3>Angular frequency of the wave</h3>
ω = 2πf
where;
f is frequency = 60 Hz
ω = 2π x 60
ω = 120π rad/s
<h3>Voltage equation as function of time</h3>
V = V₀sin(ωt)
V = 169.7sin(120πt)
