If the period of oscillation of a simple pendulum is 4s and the acceleration due to gravity is given at 9.81m/\(s^{2}\), Then the length of the pendulum is 3.975m.

The period of an oscillation is given by the reciprocal of the frequency.

It is the time taken to complete one cycle of oscillation.

The relation between the time period and length of the pendulum is,

T=2π√h/g

where T= time period.

h= length.

g= acceleration due to gravity.

In the given question,

T=4s

g=9.81m/\(s^{2}\)

To find the length, Use the relation of the time period and the length we get.

T=2π√h/g

- The resistance of the first resistor (R₁) is 12 Ω.

- The electromotive force (EMF) of the battery is 18 V.

- The internal resistance of the battery is 12 Ω.

To solve the given problem, we can apply Kirchhoff's laws and Ohm's law to determine the resistance of the first resistor (R₁) and the electromotive force (EMF) and internal resistance of the battery.

Let's start by calculating the resistance of the first resistor (R₁):

1. Apply Ohm's law to find the voltage drop across the external circuit:

  V = I * R

  V = 1 A * 6 Ω

  V = 6 V

2. The voltage drop across the external circuit is equal to the EMF minus the voltage drop across the internal resistance of the battery:

  V = E - Ir

  6 V = E - (1 A * r)   (where r is the internal resistance of the battery)

3. We also know that the EMF of the battery is the sum of the voltage drops across each cell in the battery:

  E = 6 cells * 3 V/cell

  E = 18 V

4. Substitute the value of E in the equation from step 2:

  6 V = 18 V - r

  r = 12 Ω

Therefore, the resistance of the first resistor (R₁) is 12 Ω.

The tension in the wire is caused by the elastic collision between the balls and the magnitude of this tension is determined as 18.81 N.

The speed of the balls after the collision is determined by applying the principle of conservation of linear momentum as shown below.

m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂

9.2(0) + 2.8(3.5) = 9.2v₁ + 2.8(v₂)

9.8 = 9.2v₁ + 2.8v₂   -----(1)

u₁ + v₁ = u₂ + v₂

0 + v₁ = 3.5 + v₂

v₂ = v₁ - 3.5  ---(2)

Substitute (2) into (1)

9.8 = 9.2v₁ + 2.8(v₁ - 3.5)

9.8 = 9.2v₁ + 2.8v₁ - 9.8

19.6 = 12v₁

v₁ = 19.6/12

v₁ = 1.63 m/s

v = √T/μ

v² = T/μ

T = v²μ

where;

μ is mass per unit length of the wire = 9.2/1.3 = 7.08 kg/m

The battery would have to supply 7.00 μC of charge to the capacitor.

The energy stored in the capacitor in this case is 7.98 μJ.

The battery would have to supply 4.05 mC of charge to store 1.30 J of energy in the capacitor.

The potential difference across the capacitor would be 20.2 V.

The charge supplied by the battery can be calculated using the formula Q = CV,

where Q is the charge, C is the capacitance, and V is the potential difference.

Thus,

Q = (5.00 μF)(1.40 V)

Q = 7.00 μC.

The energy stored in a capacitor can be calculated using the formula:

E = 1/2 CV^2,

where E is the energy, C is the capacitance, and V is the potential difference.

Thus,

E = 1/2 (5.00 μF)(1.40 V)^2

E = 7.98 μJ.

The charge required to store a certain amount of energy in a capacitor can be calculated using the formula:

Q = √(2CE),

where Q is the charge, C is the capacitance, and E is the energy.

Thus,

Q = √(2(5.00 μF)(1.30 J))

Q  = 4.05 mC.

The potential difference across a capacitor can be calculated using the formula V = √(2E/C), where V is the potential difference, C is the capacitance, and E is the energy.

Thus, V = √(2(1.30 J)/(5.00 μF))

V = 20.2 V

Each of the five friends needs to pay £12 to cover the cost of their own meals and contribute towards the birthday person's meal. Using mean allows us to distribute the cost equally among the friends, ensuring a fair division of expenses for the meal.

To determine how much each of the five friends needs to pay, we can use the concept of averages (mean) and divide the total cost by the number of people paying.

In this scenario, the total cost of the meal for 6 people is £12 per person. Since the other 5 friends have decided to pay for the birthday person's meal, they will collectively cover the cost of their own meals plus the birthday person's meal.

To calculate the total cost covered by the five friends, we can subtract the cost of one person's meal (since the birthday person's meal is being paid by the group) from the total cost. The cost of one person's meal is £12.

Total cost covered by the five friends = Total cost - Cost of one person's meal

= (£12 x 6) - £12

= £72 - £12

= £60

Now, to find out how much each of the five friends needs to pay, we divide the total cost covered by the five friends (£60) by the number of friends (5).

Amount each friend needs to pay = Total cost covered by the five friends / Number of friends

= £60 / 5

Answer: Newton's second law of motion

Explanation:

Answer:

2. ahead of the package.

Explanation:

Using y' - y = ut - 1/2gt², we find the time, t it takes the package to hit the ground. So, u = initial vertical velocity of package = 0 m/s, y = initial position of package = 3970 m, y' = final position of package = 0 m, g = acceleration due to gravity = 9.8 m/s².

Substituting the variables into the equation, we have

y' - y = ut - 1/2gt²

0 m - 3970 m = 0t - 1/2 × (9.8 m/s²)t²

-3970 m = -(4.9m/s²)t²

t² = -3970 m ÷ -4.9 m/s²

t² = 810.2 s²

t = √810.2 s²

t = 28.5 s

Using v = u' + at, we find the horizontal acceleration of the plane. Since the initial horizontal velocity of the package is that of the plane, u' = 162 m/s, v = 0 m/s since the package stops and t = 28.5 s when the package stops.

So, a = (v - u')/t

a = (0 m/s - 162 m/s)/28.5 s

a = -162 m/s/28.5 s

a = -5.68 m/s²

Using v² = u'² + 2as, we find the horizontal distance ,s where the package stops.

So, s =  (v² - u'²)/2a

Substituting the values of the variables, we have

s =  ((0 m/s)² - (162 m/s)²)/(2 × -5.68 m/s²)

= - 162 m²/s²/(-11.36 m/s²)

= 14.26 m

The horizontal distance d the plane moves after releasing the package is d = u't = 162 m/s × 28.5 s = 4617 m

Since d = 4617 m > s = 14.26 m, the plane would be ahead of the package when the package hits the ground.

\(H_1 =39.05 \ m\) OR \(H_2 =14.5 \ m)\)

Explanation:

From the question we are told that

The constant speed of the balloon is \(v = 6.60 \ m/s\)

The height of the balloon is \(h = 11.0 \ m\)

The initial speed of the pellet is \(u = 30 \ m/s\)

Generally the height of the balloon at the point it is the same altitude with the pellet is mathematically represented as

\(H = h + v * (t)\)

Note: vt is the distance covered by the balloon before the pellet got to it

Generally the height of the pellet when it is the same height with the balloon is mathematically represented using kinematics equation

\(s = ut + \frac{1}{2} gt^2\)

So

H = s

=> \( ut + \frac{1}{2} gt^2 = h + v * (t)\)

=> \( 30t + \frac{1}{2} *( -9.8)t^2 = 11 + 6.60t\)

=> \( 4.9t^2 -23.4t + 11= 0\)

using the quadratic formula to solve the above equation

From the quadratic formula calculation

\(t_1 = 4.25 \ s\)

   OR

     \(t_1 =  0.529  \  s\)

So the height of this two place above the ground is mathematically evaluated as

\(H_1 = h + v * (4.25)\)

\(H_1 = 11 + 6.60 * (4.25)\)

\(H_1 =39.05 \ m\)

OR

\(H_2 = h + v * ( 0.529)\)

\(H_2 = 11 + 6.60 * (0.529)\)

       \(H_2  =14.5 \  m)\)
