Doppler radars work by using radio waves that bounce off objects and thus the object can be tracked.

Doppler radars work by emitting a beam of energy from an antenna known as radio waves. The energy they release when they collide with airborne objects scatters in all directions, with some of it returning directly to the radar.

The quantity of energy returned to the radar increases with object size. We can now perceive raindrops in the atmosphere because of this.

The amount of time it takes for the energy beam to be delivered and returned to the radar also gives us the object's distance.

Explanation:

Yes, there are differences in the shapes of position-time graphs for uniform acceleration and uniform deceleration in different directions. Let's consider each case separately:\(\hrulefill\)

(1) - Uniform acceleration towards the positive direction:

In this case, the object is moving in the positive direction with a constant acceleration. The displacement-time graph will typically be a curve that starts from an initial position and shows a steady increase in displacement over time. The shape of the graph will depend on the specific acceleration value.

(2) - Uniform acceleration towards the negative direction:

In this case, the object is moving in the negative direction with a constant acceleration. The displacement-time graph will also be a curve, but it will show a steady decrease in displacement over time.

(3) - Uniform deceleration towards the positive direction:

In this case, the object is initially moving in the positive direction but is slowing down with a constant deceleration. The displacement-time graph will be a curve that starts with a positive slope and gradually levels off.

(4) - Uniform deceleration towards the negative direction:

In this case, the object is initially moving in the negative direction but is slowing down with a constant deceleration. The displacement-time graph will be a curve that starts with a negative slope and gradually levels off.

Answer:

Force = 5.22 N

Explanation:

According to Newton's Second Law of motion:

\(Force = Rate\ of\ Change\ of\ Momentum\\\\Force = \frac{mv_f-mv_i}{t}\\\)

where,

m = mass of ball = 145 g = 0.145 kg

vf = final speed of ball after hit = 25 m/s

vi = initial speed of ball before hit = -  11 m/s (negative sign due to opposite direction)

t = time of contact = 1 s

Therefore,

\(Force = \frac{(0.145\ kg)(25\ m/s)-(0.145\ kg)(-11\ m/s)}{1\ s} \\\\\)

The speed of the ball as seen by a stationary observer in the street will be the sum of the speed of the ball relative to the bus and the speed of the bus relative to the observer.

From the viewpoint of a stationary observer on the street, the ball and the school bus are both moving forward at the same constant velocity. Therefore, the speed of the ball as seen by the observer in the street will be the sum of the speed of the ball relative to the bus and the speed of the bus relative to the observer.

Assuming the ball is thrown horizontally and neglecting any air resistance, the speed of the ball relative to the bus will be constant and equal to the speed at which the ball was thrown. However, since the bus is moving forward, the speed of the ball relative to the observer in the street will be the sum of the speed of the ball relative to the bus and the speed of the bus relative to the observer.

Suppose, if the bus is traveling at a speed of 20 km/h and the ball is thrown at a speed of 10 km/h relative to the bus, then the speed of the ball as seen by the observer in the street will be 30 km/h (20 mph + 10 km/h).  Therefore, the speed of the ball as seen by a stationary observer in the street will be the  of the relative speed of the ball relative to the bus and the speed of the bus relative to the observer.

For a spacecraft is traveling with a velocity of Vox-5690 m/s:

To solve this problem, use the equations of motion to calculate the final velocity and the vertical component of the velocity. Assume that the initial velocity in the y-direction is zero.

Given:

Initial velocity in the x-direction (V₀ₓ) = -5690 m/s

Time of engine firing (t) = 865 s

Acceleration in the x-direction (ax) = 1.45 m/s²

Acceleration in the y-direction (ay) = -8.66 m/s²

(a) To calculate the final velocity (v), use the equation:

v = V₀ₓ + ax × t

Substituting the values:

v = -5690 m/s + 1.45 m/s² × 865 s

v = -5690 m/s + 1254.25 m/s

v ≈ 685.25 m/s

Therefore, the final velocity (v) is approximately 685.25 m/s.

(b) To calculate the vertical component of the velocity (vy), use the equation:

vy = ay × t

Substituting the values:

vy = -8.66 m/s² * 865 s

vy = -7484.9 m/s

Answer:

a. The laser tracking mechanism experiences a changing tangential velocity

c. The laser tracking mechanism experiences a non-zero angular acceleration

d. The laser tracking mechanism experiences a non-zero tangential acceleration

Explanation:

a. The laser tracking mechanism experiences a changing tangential velocity

This is because the tangential velocity v = rω where r = radius of disc and ω  = angular speed of discs. Since r is constant, v ∝ ω.

Since the angular speed changes from 200 rpm to 500 rpm, thus, the tangential velocity would also change.

So, the laser tracking mechanism experiences a changing tangential velocity

c. The laser tracking mechanism experiences a non-zero angular acceleration

Since angular acceleration, α = Δω/Δt where Δω = change in angular speed and Δt = change in time.

Since there is a change in angular speed from 200 rpm to 500 rpm in time Δt, there is thus a non-zero angular acceleration.

So, The laser tracking mechanism experiences a non-zero angular acceleration

d. The laser tracking mechanism experiences a non-zero tangential acceleration

Since tangential acceleration, a = rα where r = radius of disc and α = angular acceleration.

Since there is an angular acceleration of the disc, there is thus going to be a tangential acceleration given by a = rα.

So, the laser tracking mechanism experiences a non-zero tangential acceleration

Statement b is false because, the disc experiences a changing angular speed from 200 rpm to 500 rpm.

Explanation:

Data is factual information not subject to bias.

This ultimately implies that, data connotes fact, thus, it is an information that is credible, accurate, a statement of truth, evidential and proven.

In Computer programming, a data dictionary can be defined as a centralized collection of information on a specific data such as attributes, names, fields and definitions that are being used in a computer database system.

In a data dictionary, data elements are combined into records, which are meaningful combinations of data elements that are included in data flows or retained in data stores.

This ultimately implies that, a data dictionary found in a computer database system typically contains the records about all the data elements (objects) such as data relationships with other elements, ownership, type, size, primary keys etc. This records are stored and communicated to other data when required or needed.

It would take approximately 546 days for the decay rate of the sample of this radioactive isotope to fall to 0.58 of its initial rate.

1. The decay rate of a radioactive isotope is proportional to the number of radioactive atoms present in the sample at any given time.

2. The decay rate can be expressed as a function of time using the formula: R(t) = R₀ * \(e^{(-\lambda t\)), where R(t) is the decay rate at time t, R₀ is the initial decay rate, λ is the decay constant, and e is the base of the natural logarithm.

3. The half-life of a radioactive isotope is the time it takes for half of the radioactive atoms in a sample to decay. In this case, the half-life is given as 210 days.

4. Using the half-life, we can find the decay constant (λ) using the formula: λ = ln(2) / T₁/₂, where ln(2) is the natural logarithm of 2 and T₁/₂ is the half-life.

5. Substituting the given half-life into the formula, we have: λ = ln(2) / 210.

6. Now, we need to find the time it takes for the decay rate to fall to 0.58 of its initial rate. Let's call this time "t".

7. Using the formula for the decay rate, we can write: 0.58 * R₀ = R₀ * e^(-λt).

8. Simplifying the equation, we get: 0.58 = \(e^{(-\lambda t\)).

9. Taking the natural logarithm of both sides, we have: ln(0.58) = -λt.

10. Substituting the value of λ from step 5, we get: ln(0.58) = -(ln(2) / 210) * t.

11. Solving for t, we have: t = (ln(0.58) * 210) / ln(2).

12. Evaluating the expression, we find: t ≈ 546.

13. Therefore, it would take approximately 546 days for the decay rate of the sample of this radioactive isotope to fall to 0.58 of its initial rate.

Explanation:

An archer shoots an arrow with a velocity of 45.0 m/s at an angle of 50.0° with the horizontal. An assistant standing on the level ground 150 m downrange from the launch point throws an apple straight up with the minimum initial speed necessary to meet the path of the arrow. (a) The initial speed of the apple is 30.352m/s. (b)The time taken by arrow to reach this point is 5.185 s. So, the apple should be thrown 2.09s after the arrow launch.

Velocity is a term defines that a particle covered distance in a particular time. It is a vector quantity. it can be measured in m/s or cm/s.

(a) To calculate the velocity we are using the formula, y₂=v*t - 1/2 *g*t²

Now we are given,

Let the speed of apple be v(min)

Time taken by arrow to reach P is

t = (x₂- x₁)/(v₁ * cosθ )

t= (150m)/(45*cos 50°)

t= 5.185s

Vertical distance covered by arrow

y₂ = y₁ + (v₁ * sin θ) * t - 1/2 * g * t²

y₂ = (45sin 50 deg)(5.185) - (4.9) * (5.185)²

y₂= 47.0046m

The apple also covers the same distance (vertically) in this time

So, for the apple

v₁*t - 1/2*g*t² = 47.0046m

4.9t² - v*t + 47.0046 = 0

v = (1/t) * [4.9t² + 47.0046]

v= 4.9t + 47.0046/t

For minimum velocity of apple,

(dv)/(dt) = 0

4.9 - 47.0046/(t²) = 0

t = 3.0972s

v(min) =v (at,3.0972)

= 4.9 * 3.0972 + (47.0046/3.0972)

=  30.352m/s

According to the calculation we can say that, The initial speed of the apple is 30.352m/s.

(b) From part (a) we knew that for v(min) , t = 3.0972s and the time taken by arrow to reach this point is 5.185 s.

So, the apple should be thrown 5.185 - 3.0972 = 2.0878s

=  2.09s

after the arrow launch.

According to the calculation we can say that, The time taken by arrow to reach this point is 5.185 s. So, the apple should be thrown 2.09s after the arrow launch.

The wave which carries energy twice as the energy of the wave shown is the wave in option c. The amplitude of the wave and wave cycles increased twice in the wave in option c.

The amplitude of a wave is the distance from the center of a baseline under the crest to the top of the crest. The amplitude of the wave is the measure of its intensity.

The amplitude and energy of a wave is directly proportional to the frequency of the wave. Hence, as the frequency increases, the amplitude of the wave increases.
