The magnitude of the acceleration of the system is equal to 1.96 m/s². The tension in the string is equal to 4.70 N.

What is Newton's second law of motion?

Newton's 2nd law of motion described the force acting on an object as equal to mass (m) times the acceleration (a) of that object.

The mathematical relation can be shown as follows:

F = ma

Given, the mass, m = 0.40 Kg  and the mass M = 0.60 Kg

From newton's second law:  Mg - T = Ma            ...........(1)

Similarly, T - mg =ma                                    ...............(2)

By adding both equations, we get:

(M - m)g = (M + a)a

(0.60 - 0.40) (9.8) = (0.60 + 0.40) a

a = 1.96 m/s²

The tension in the string can be determined as:

Mg - T = Ma

(0.60) (9.8) - T = (0.60) × 1.96

T = 4.70 N

The resultant velocity of the golf ball is 18.03 m/s

What is Resultant velocity?

An object's total vector velocity is the sum of its component vector velocities. The scalar product of an object's mass and acceleration vector equals the sum of the vector forces acting on it. If indeed the two objects stick together again after impact, divide the total momentum even by sum of the masses. You will then be given the two objects' resultant velocity as a result. In the aforementioned example, 50 would be divided by the total mass of the masses, which really is 10, yielding a speed of 5 metres per second.

Horizontal velocity= 10 m/s

Vertical velocity= 15 m/s

Capacitance is the ability of an object or device to store an electric charge. It is measured by the change in charge in response to a potential difference and is expressed as a ratio of these quantities.

For charge:

Q = CV

Where Q = Charge

C = Capacitance (45 μF or 45 × 10⁻⁶ F)

V = Voltage applied (100 V)

Q = 45 × 10⁻⁶ × 100

Q = 45 × 10⁻⁴ C

For angular frequency:

ν = 1/√(LC)

ν = angular frequency

L = Inductance (45 mH or 45 × 10⁻³ H)

C = Capacitance (45 μF or 45 × 10⁻⁶ F)

ν =  1/√(45 × 10⁻³ × 45 × 10⁻⁶ )

ν =  1/4.5 × 10⁻⁵

ν =  0.22 × 10⁵ H or 22 × 10³ H

For the period of electric oscillation:

t = 1/ν

t = period of electric oscillation

ν = angular frequency (22 × 10³ H)

t = 1/22 × 10³

t = 4.5 × 10⁻⁵ sec

Now, for current:

Q = It

I = Q/t

I = current

Q = Charge (45 × 10⁻⁴ C)

t = time (4.5 × 10⁻⁵ sec)

I = 45 × 10⁻⁴ / 4.5 × 10⁻⁵

I = 1 A

If the time is 2.9 ms, then charge and current will be

Q = It

Q = 1 × 2.9 × 10⁻³

Q = 2.9 × 10⁻³ C

I = Q/t

I = 2.9 × 10⁻³/2.9 × 10⁻³

Solution:

v = p/m

v = 40,000 kg x m/s

1,400 kg

v = 28.6 m/s

Average velocity is a measure of total displacement divided by total time. The total displacement is the distance between the start and endpoints. Since the car moves from point A at both the start and end points the total displacement is zero and the average velocity is also zero.

Velocity is the distance traveled per unit of time, the speed of movement. The speed of a car traveling on a smooth, flat section of a highway without traffic congestion is constant and not zero.

The crate (92 kg) will be slide on the rough floor with kinetic friction about 0,2.

Minimum force is required to allow the crate moves, which is calculated as follows :

Kinetic friction is formed because there are two or more things are sliding together. In this case, crate and floor are rubbing each other. Kinetic friction can cause the speed of things decreased.

Crate need a bigger force than the friction one to make it move.

So, we can calculate the value of a kinetic friction first.

f = μ x N

f = friction (Newton)

μ = coefficient of kinetic friction

N = Normal force (Newton)

f = μ × N

f = 0,2 × m × g

f = 0,2 × 92 × 10

f = 2 × 92 = 184 N

The heaviest liquid is mercury. In order to equalize the air pressure, it only climbs 76 cm. Water will rise to a 13.6 because it is 13.6 times lighter than mercury. By a factor of 13.6, mercury is 13.6 times denser than water.

Therefore, the barometer's height would be 13.6 times higher if water were employed in place of mercury. Since water expands when it freezes, the glass tube would be broken.

Because of its high density, mercury is frequently employed in barometers, allowing for a column height that is appropriate for measuring atmospheric pressure. For example, a mercury barometer would need to be 13.6 times taller than a water barometer to measure the same change in pressure.

The accurate measurement of an object's position and speed is its velocity. It is the distance that an item travels in one unit of time. The displacement of the item in one unit of time is the concept of velocity.

Using the formula for the horizontal range, we will first determine the ball's projectile motion's launch velocity:

R = u²sin 2θ/g

where,

R = horizontal range = 301.5 m

u = launch speed = ?

θ = launch angle = 25°

Gravity's acceleration, or g, is 9.81 m/s2²

Therefore,

301.5 m =  u²sin 50 /9.81 m/s²

u  = √(301.5 m)(9.81m/s²) / sin 50

u = 62.14 m/s

Now, using the following formula, we will determine the projectile motion's maximum height (H):

H = u²sin²θ

H  = (62.14m/s²) sin²(25⁰) / 2(9.81 m/s²)

Mass times acceleration, or F=m x a, equals force. This means that in order to move an object at the same speed as an object with smaller mass, a stronger force is required. Newton's Second Law of Motion is this.

Acceleration = Force / Mass

Given, as per question in all the 4 options Force = 120 N same for all

So as per formula if we assume Force is constant

Then, if mass is increased then acceleration will be lowest as both are inversely proportional.

1. Acceleration= 120 / 4.25 = 28.23 m/s²

2. Acceleration= 120 / 3.25 = 34.28 m/s²

Given parameters:

Initial velocity of the First stone; u₁ = 11 m/s.

Initial velocity of the Second stone; u₂= 0 m/s.

Height of both cases; h = 110 m.

Acceleration due to gravity; g = 9.8 m/s².

So, If time taken by the first stone is t₁; then

h = u₁t₁ + 1/2 * gt₁²

⇒ 110 = 11 t₁ + 1/2*9.8 t₁²

⇒ 4.9 t₁² + 11 t₁ -110 = 0

So, by solving this quadratic equation we get: t₁ =3.73s.

And if time taken by the second stone is t₂; then

h = 1/2*g t₂²

⇒ t₂ = √(2h/g) = √(2×110/9.8) = 4.74 s.
