A stationary speed gun emits a microwave beam at 2.10x10^10 Hz. It reflects off a car and returns 638 Hz lower. What is the speed of the car? (Unit=m/s)
Answer:
The answer is 4.55 m/s!
Explanation:
I wish you luck with Acellus! We got 15 days left!
Please mark brainliest.
The speed of the car will be approximately 9.14 meters per second.
To find the speed of the car, we can use the Doppler effect equation for frequency shift:
Δf/f₀ = v/c
where:
Δf = frequency shift (638 Hz lower in this case)
f₀ = original frequency emitted by the speed gun (2.10x10¹⁰ Hz)
v = velocity of the car
c = speed of light in a vacuum (approximately 3.00x10⁸ m/s)
We need to rearrange the equation to solve for the velocity (v) of the car:
v = Δf/f₀ × c
Now, let's plug in the values:
Δf = 638 Hz
f₀ = 2.10x10¹⁰ Hz
c = 3.00x10⁸ m/s
v = 638 Hz / 2.10x10¹⁰ Hz × 3.00x10⁸ m/s
Calculate the value:
v ≈ 9.14 m/s
So, the speed of the car is approximately 9.14 meters per second.

If a race car is traveling South due to a 30N force and the parachute deploys resulting in a 10N force North what is the Net Force (or Resultant Force)?
a) 40n east
b) 40n south
c) 10n west
d) 20n south
Answer:
F = 20 N south
Explanation:
It is given that,
Force applied on the racing car in south direction is 30 N and parachute deploys resulting in a 10 N force due North.
We need to find the net force on the car.
Let North denotes +y axis and South denotes -y axis.
So, F₁ = +10 N
F₂ = -30 N
Net force is :
[tex]F=F_1+F_2\\\\F=10+(-30)\\\\F=-20\ N[/tex]
It means that the net force is 20 N and it is acting in south. Hence (d) is correct.

A point charge Q = -400 nC and two unknown point charges, q1 and q2, are placed as shown. Point charge q1 is located 1.3 meters along the +x-axis, point charge q2 is located 0.7 meters down the -y-axis, and point charge Q is located 2.0 meters from the origin at an angle of 30° above the x-axis. At the origin, the three charges together create an electric field that has magnitude zero. What is the charge q1?
150 nC
120 nC
–120 nC
–150 nC
250 nC
To find the charge q1, set up equations for the electric fields created by each charge and solve them simultaneously. The value of q1 is -150 nC.
Explanation:To find the charge q1, we need to consider the electric field created by each of the three charges separately. Since the total electric field at the origin is zero, the electric fields from charges Q, q1, and q2 must sum up to zero.
We can use the formula for the electric field due to a point charge, which is given by E = k * Q / r^2, where k is the electrostatic constant, Q is the charge, and r is the distance from the charge to the point of interest. By setting up equations for the electric fields from each charge and solving them simultaneously, we can find the value of q1.
After solving the equations, we find that the charge q1 is equal to -150 nC.

A ball is dropped from rest from a Cliff and falls for 3 seconds.
Neglecting air resistance, the final velocity of the ball is
m/s. (g = -9.8 m/s2)
Enter the answer
Answer:
-29.4 m/s
Explanation:
Given:
v₀ = 0 m/s
t = 3 s
a = -9.8 m/s²
Find: v
v = at + v₀
v = (-9.8 m/s²) (3 s) + (0 m/s)
v = -29.4 m/s
The final velocity of a ball dropped from rest for 3 seconds is -29.4 m/s.
How to find final velocity?Given the following information:
The ball is dropped from rest.
The acceleration due to gravity is g = -9.8 m/s².
The time the ball falls is t = 3 seconds.
Use the following formula to calculate the final velocity of the ball:
v = v_0 + g × t
where:
v is the final velocity of the ball
v_0 is the initial velocity of the ball (which is 0 in this case)
g is the acceleration due to gravity
t is the time
v = 0 + (-9.8 m/s²) × 3 seconds
v = -29.4 m/s
Therefore, the final velocity of the ball is -29.4 m/s.
The negative sign indicates that the velocity is downwards.

An 11.98-gram sample of zinc metal is placed in a hot water bath and warmed to 78.4°C. It is then removed and placed into a Styrofoam cup containing 50.0 mL of room temperature water (T=27.0°C; density = 1.00 g/mL). The water warms to a temperature of 28.1°C. Determine the specific heat capacity of the zinc.
Answer:
383.34 J/kg.K
Explanation:
From the question,
Heat lost by zinc = heat gained by water in the Styrofoam cup.
c'm'(t₁-t₃) = cm(t₃-t₂).............. Equation 1
Where c' = specific heat capacity of zinc, m' = mass of zinc, t₁ = initial temperature of zinc, t₂ = initial temperature of water in the Styrofoam cup, t₃ = temperature of the mixture
Make c' the subject of the equation
c' = cm(t₃-t₂)/m'(t₁-t₃).............. Equation 2
given: m' = 11.98 g = 0.01198 kg, m = density of water×volume of water = (1×50) = 50 g = 0.05 kg, t₁ = 78.4°C, t₂ = 27°C, t₃ = 28.1°C
Constant: c = 4200 J/kg.K
Substitute these values into equation 2
c' = 0.05×4200(28.1-27)/[0.01198×(78.4-28.1)]
c' = 231/0.602594
c' = 383.34 J/kg.K

Why has the study of genetic differences in intelligence been so controversial?
A.
Genetics has no role in intelligence.
B.
The studies didn’t really measure differences in genetics.
C.
The idea of genetic differences has often been used to justify racial discrimination.
D.
All of the above
The controversy over genetic differences in intelligence primarily relates to the misuse of genetic arguments for racial discrimination and the oversight of environmental influences on intelligence.
Explanation:The study of genetic differences in intelligence has been controversial due to several factors. The primary concern arises from the historical use of genetic arguments to justify racial discrimination. These views, although scientifically refuted, have at times resurged, as in the case of 'The Bell Curve'. Notably, the controversy arises from interpretations that link genetics and race with intelligence without accounting for the significant influence of environmental variables. Additionally, research has shown a closing of IQ gaps with increased access to education, pointing to nurture's critical role in intelligence development. The persistence of the idea that intelligence could be predetermined by race without adequate consideration of environment and socioeconomic factors contributes to the ongoing debate.
Moreover, there is a recognition that intelligence is affected both by genetics and environment, with environmental influences shaping the manifestation of cognitive abilities. Twin studies show a genetic component to intelligence, but conflict theorists note that IQ tests can be biased and do not always offer a fair assessment of a person's intellectual capabilities, reinforcing the complex interplay of genetics, environment, and social factors in the development of intelligence.
Two boats are anchored in the harbor, separated by a horizontal distance of 18 m. The boats bob up and down as waves enter the harbor. When one boat is at its highest point, the other is at its lowest point and there is one wave crests between them. Each boat makes exactly 2 complete up-and-down cycles every 16.0 s. The vertical distance between a boat's highest and lowest position is 3.6 m.
Final answer:
The amplitude of a wave is half the height from peak to trough, so a 2 m crest above still water has an amplitude of 1 m. A seagull bobbing every 2 seconds between 3 m apart crests experiences a wave velocity of 1.5 m/s. A boat hit by a 2 m high wave peak will change elevation by 2 m.
Explanation:
The question provided is related to the physics of waves, specifically their propagation, amplitude, frequency, and wavelength. When discussing a wave crest measuring 2 m above the still water mark, the amplitude of the wave is actually 1 m, as the amplitude corresponds to the maximum displacement from the equilibrium (still water level) to the peak of the wave, which would be half of the peak-to-trough height.
Therefore, if a wave's crest is 2 m above the still water mark, and assuming the trough is the same distance below, the amplitude is 1 m.
Similarly, for a seagull bobbing up and down on the water's surface, if it does so once every two seconds and the distance between two crests of the water wave is 3 m, the velocity of the wave would be 1.5 m/s (wavelength divided by the period: 3 m / 2 s = 1.5 m/s).
Regarding a boat that bobs up and down due to wave action, if the height of the wave is 2 m, the boat's height will change by 2 m when hit by the peak of the wave, considering the change from the equilibrium position to the peak.
