The equation for the position vector r(t) of the particle at time t is :r(t) = 3i + 8j + 8k + (7i + 0j + 0k)t + (5/2i + 1/2j - 2k)t²

Given,Initial velocity, v0= 7 m/s

Final velocity, v = ?

Acceleration, a= 5i + j - 4k

Time, t = ?

Distance between the points, d= √(8 - 3)² + (9 - 8)² + (4 - 8)²

                                                    = √25 + 1 + 16

                                                    = √42 m

We know that,v = v0 + at

On substituting the given values in the above equation, we get,

7 + a×t = v

⇒ v = 7 + (5i + j - 4k)×t

Now, the equation of motion can be given by the following equation,r(t) = r0 + v0t + 1/2at²

Here,r0 = (3i + 8j + 8k) is the initial position of the particle

On substituting the given values in the above equation, we get,

r(t) = 3i + 8j + 8k + (7i + 0j + 0k)t + (5/2i + 1/2j - 2k)t²

Hence, The particle's location vector at time t is represented by the equation:r(t) = 3i + 8j + 8k + (7i + 0j + 0k)t + (5/2i + 1/2j - 2k)t²

(a) To determine the number of electrons necessary to produce a charge of -1.2C, we need to consider the elementary charge. The elementary charge represents the charge carried by a single electron, which is approximately -1.6 × 10^-19 coulombs. Dividing the given charge by the elementary charge, we find the number of electrons.

Number of electrons = -1.2C / (-1.6 × 10^-19C/electron) ≈ 7.5 × 10^19 electrons

(b) To calculate the mass of this many electrons, we utilize the mass of a single electron. The mass of an electron is approximately 9.1 × 10^-31 kilograms. Multiplying the number of electrons by the mass of a single electron, we obtain the mass.

Mass of electrons = (7.5 × 10^19 electrons) × (9.1 × 10^-31 kg/electron) ≈ 4.8 × 10^-17 kilograms

Therefore, the charge of -1.2C corresponds to approximately -7.5 × 10^19 electrons, and the mass of this many electrons is approximately 4.8 × 10^-17 kilograms.

Work was done on the train 225x10⁵ J

Power exerted by the train 1.07 x 10⁵ W

Work is the amount of energy transferred to an object when it is moved a certain distance by an external force. Since work is defined as the amount of energy (transferred), it has units of energy, and work usually has units of J (joules). The equation describing the work (W) done on a body moving a distance (s) while a force (F) is acting on it in the same direction as its motion is given by:

W = F × s

Where,

W = work done

F = force applied

s = displacement

We can define force as the rate of work. It is work done in a unit of time. The SI unit for power is the watt (W), which is the joule per second (J/s). The formula for power is:

P = W / t

Where,

P = Power

W = work done

t = time taken

Now for the given question:

W = F × s

F = 5.0x10⁴ N

s =  450.0 meters

W = 5.0x10⁴ x 450.0

W = 225x10⁵J

P = W / t

P = \(\frac{225}{210}\) x10⁵

P =1.07 x 10⁵ W

Answer:

The elongation of the wire is approximately 4.81 x 10-³ m.

Explanation:

To find the elongation of the wire, we can use the formula:

Elongation = (Force * Length) / (Young Modulus * Cross Sectional Area)

Plugging in the given values, we have:

Elongation = (10³ N * 2.5 m) / (2.0 x 10-¹¹ N/m² * 6.5 x 10-⁷ m²)

We can simplify this to:

Elongation = (2500 N * 2.5 m) / (2.0 x 10-¹¹ N/m² * 6.5 x 10-⁷ m²)

Which simplifies to:

Elongation = (625 x 10-⁸ m³) / (1.3 x 10-¹¹ m³)

Simplifying further, we have:

Elongation = 4.81 x 10-³ m

Therefore, the elongation of the wire is approximately 4.81 x 10-³ m.

It's important to note that this is an approximate value, as the actual elongation may depend on various factors such as the temperature and the specific properties of the wire.

The ratio of the height attended by the object thrown upward to that thrown at some angle θ with the vertical is 1.  

Note: It is assumed that the mass of the first object is m and the mass of the second object is 2m. Also, the first object is thrown upward and the second object is thrown at some angle θ with the vertical.

Projectile motion: Any object that is thrown in the air is called a projectile and the motion described by it under gravity is called the projectile motion.  

If the air resistance is neglected, then the acceleration due to gravity g is the same for all objects irrespective of their masses. It is given that both objects remain in the air for the same time period. So first calculate the time period for the objects when they are in the air.

Time period of the first object: The first object is thrown in the air upwards so from the second kinematics equation,

h1=u1*t1-(1/2)*gt1^2

where h1 is the height, t1 is the time, and u1 is the initial velocity for the first object.

When the object is not in air h1=0, so

0=u1*t1-(1/2)*gt1^2

After solving the above quadratic equation, the values of t1 obtained are t1=0 which represents the initial time, and t1=2u1/g which represents the time period. So the time period of the first object is,

t1=2u1/g

Time period of the second object: The second object is thrown at some angle θ with the vertical as shown in the diagram. From the diagram, the initial velocity along the vertical direction is,

u2=uocos(θ)

where uo is the initial velocity and u2 is the initial velocity along the vertical direction.

From the second kinematic equation,

h2=u2*t2-(1/2)*gt2^2

where h2 is the height, t2 is the time, and u2 is the initial velocity for the second object along the vertical direction.

When the object is not in air h2=0, so using u2=uocos(θ),

0=uocos(θ)*t2-(1/2)*gt2^2

After solving the above quadratic equation, the values of t2 obtained are t2=0 which represents initial time, and t2=2uocos(θ)/g which represents  the time period. So the time period of the second object is,

t2=2uocos(θ)/g

Given that the time period is the same for both cases,

t1=t2

2u1/g=2uocos(θ)/g

u1=uo cos(θ)

Calculation of the ratio of the height of the object:

The maximum height is attained when the time of the object in the air is half of the total time period. At maximum height, velocity is zero.

From the third equation of motion.

v^2=u^2-2gh

h=u^2/2g

where h is the height and u is the initial velocity of an object.

Using it and u1=uo cos(θ) and u2=uo cos(θ), the ratio of h1 and h2 is,

h1/h2=  u1^2/2g÷u2^2/2g

h1/h2=(uo cos(θ))^2/(uo cos(θ))^2

h1/h2=1

The ratio of their height will be 1.

Given the input pressure (P1) = 1200Pa

Output force (F2) = 800N

We know that P= F/A where A is area of cross section

Let the input force be F1 and area is A1
