Explanation:

but velocity is basically the speed on something

Answer:

The meaning of velocity of an object can be defined as the rate of change of the object’s position with respect to a frame of reference and time. It might sound complicated but velocity is basically speeding in a specific direction. It is a vector quantity, which means we need both magnitude (speed) and direction to define velocity.

The SI unit of it is meter per second (ms-1). If there is a change in magnitude or the direction in the velocity of a body the body is said to be accelerating.

Answer:

A. 40 N

Explanation:

To find force with acceleration and mass we use the equation f=ma

f stands for force

m stands for mass

a stands for acceleration

Now we substitute

f=50*0.8

f= 40

Remember that force is measured in newtons. So A. 40 N is the correct answer.

Use the formula a = v / t to determine acceleration, where v stands for the change in velocity and t for the time it took for the change to take place. Use SI units for force (newtons), mass (kg), and acceleration when utilizing this formula (meters per second squared). Thus, option A is correct.

The acceleration of an object is equal to the net force exerted on it divided by its mass, or a = F m, in accordance with Newton's second rule of motion. When the mass of an item and the net force acting on it are known, the acceleration of that object can be determined using this equation for acceleration.

Therefore, An object's force is equal to its mass times its acceleration, or F = m a. To apply this formula, you must use SI units for force (newtons), mass (kilograms), and acceleration (meters per second squared).

The kinetic energy of the book after it is slids a distance of 2 meters will be 10 Joules.

The work-energy theorem states that "the work done on an object is the change in its kinetic energy".

Hence;

Kinetic energy = work done

Note that: work-done is expressed as:

Work done = f × d

Where f is force applied and d is distance traveled.

Given that:

Force applied f = 5 newton

Distance d = 2 meters

Work done = ?

Plug these values into the above formula and solve for the workdone.

Work done = f × d

Work done = 5N × 2m

Work done = 10Nm

Work done = 10 Joules

Therefore, the kinetic energy is 10 Joules.

The magnitude of the force acting at point O is determined as 240 N.

The magnitude of the force at point O is calculated by applying the principles of moment as shown below.

Answer:

1 by 3 units

Explanation:

The resistance (R) of a conductor is given by the formula:

R = ρL / A

where L is the length of the conductor, ρ is resistivity and A is the cross sectional area.

Let us assume that the metal bar has a resistivity of ρ.

a) If the leads is attached to the two opposite sides that have dimensions of 1 by 3 units.

The length of the bar would be 13 units and the cross sectional area (A) would be = 1 * 3 = 3 units²

R₁ = ρL / A =  ρ(13) / 3 = 13ρ / 3

b) If the leads is attached to the two opposite sides that have dimensions of 3 by 13 units.

The length of the bar would be 1 units and the cross sectional area (A) would be = 3 * 13 = 39 units²

R₂ = ρL / A  = ρ(1) / 39 = ρ / 39

c) If the leads is attached to the two opposite sides that have dimensions of 1 by 13 units.

The length of the bar would be 3 units and the cross sectional area (A) would be = 1 * 13 = 13 units²

R₃ = ρL / A = ρ(3) / 13 = 3ρ / 13

Therefore we can see that the largest resistance is gotten If the leads is attached to the two opposite sides that have dimensions of 1 by 3 units

Explanation:

Answer:

3 m/s

The northward component of the puck’s velocity is 3 m/s

Explanation:

Applying the impulse momentum equation;

Impulse = change in momentum

Ft = m(∆v)

∆v = Ft/m

F = force = 6.0 N due north

t = time = 1.5 s

m = mass = 3.0 kg

Substituting the values;

Change in velocity ∆v = (6 × 1.5)/3.0 = 9/3

∆v = 3 m/s due north

And since the initial northward component of the puck’s velocity is zero.

The final northward component of the puck’s velocity is;

v = 0 + 3 m/s

v = 3 m/s

The northward component of the puck’s velocity is 3 m/s

The electrical force between the two charges can be calculated as +1.8×10⁻² N and its repulsive.

To find the electrical force, distance = 2 meters

charge q1 = 2×10⁻⁶ C

charge q2 = 4×10⁻⁶ C

         The force of attraction or repulsion acting along a straight line between two electric charges is directly proportional to the product of the charges and inversely to the square of the distance between them.

Formula can be written as,

          F = K ( q1q2 / r² )

F - electric force

k - Coulomb constant

q1, q2 - charges

r - distance of separation

Substituting the values in the formula,

         F = 9 × 10⁹ Nm²/C² ( (2×10⁻⁶ C ×  4×10⁻⁶ C) / (2²))

            = 0.0179751

         F = 1.8 × 10 ⁻² N.

As both the charges q1 and q2 are positive, the charges gets repulsive.

Answer:

Explanation:

on earth, objects in free fall accelerate downward at approximately 10 m/s²

any small initial velocity is irrelevant.

With the use of below formula, at 879 °C,  velocity will be double the velocity at 15 °C.

The velocity of sound waves in air is proportional to the square root of Thermodynamic temperature. That is, V = K\(\sqrt{T}\)

Given that the temperature at which the velocity of sound in air is twice its velocity at 15°C, Let us make use of the formula;

(v2/v1) = √(T2 / T1)

Where

Recall that absolute temperature = °C + 273.

If v2 = 2 × v1 and temperature in degree Celsius = 15°C, then,

Temperature in Kelvin K = 15 + 273 = 288

Substitute all the parameters into the formula

(2 × v1)/v1 = √(T2/288)

2 = √ (T2 /288)

Square both sides

4 = (T2/288)

T2 = 4 × 288

T2 = 1152K

Temperature in degrees Celsius = 1152 - 273 = 879 °C.

Therefore, at 879 °C,  velocity will be double the velocity at 15 °C.

Acceleration is defined as the change in velocity per unit time. Its unit is m/s².

Distance is the amount of space, or the actual length of the path travelled.

Displacement is the difference between the initial and final positions of the object.

Speed is the rate at which an object covers a certain distance.

Velocity is defined as the speed with a direction.

An object is said to have a positive velocity, if it is moving in the positive direction. And an object moving in negative direction has a negative velocity.

Acceleration is the change in velocity per unit time.

For freely falling objects, gravity is the only thing acting on the object.

The acceleration due to gravity on the earth is 9.8 m/s².

The average acceleration of the motorcycle over the given distance is approximately 9.39 m/s².

To calculate the average acceleration of the motorcycle, we can use the formula:

Average acceleration = (final velocity - initial velocity) / time

First, let's convert the final velocity from km/h to m/s since the distance is given in meters. We know that 1 km/h is equal to 0.2778 m/s.

Converting the final velocity:

Final velocity = 78 km/h * 0.2778 m/s = 21.67 m/s

Since the motorcycle starts from rest (initial velocity is zero), the formula becomes:

Average acceleration = (21.67 m/s - 0 m/s) / time

To find the time taken to reach this velocity, we need to use the formula for average speed:

Average speed = total distance/time

Rearranging the formula:

time = total distance / average speed

Plugging in the values:

time = 50 m / 21.67 m/s ≈ 2.31 seconds

Now we can calculate the average acceleration:

Average acceleration = (21.67 m/s - 0 m/s) / 2.31 s ≈ 9.39 m/s²

Explanation:

I = M g sin / (L  B), where M, L,, and B are the provided variables and g is the acceleration due to gravity (9.81 m/s2), determines the amount of current in the wire that will keep it at rest.

The magnitude of the magnetic field is inversely related to the perpendicular distance from the wire and proportionate to the current.

We need to use the equation for the force on a current-carrying wire in a magnetic field to estimate the size of the current in the wire that will keep it at rest:

F = I L × B

The weight of the wire's component moving down the incline must be balanced by the force acting on the wire:

F = M g sinθ

For the wire to remain at rest, these two forces must be equal:

I L × B = M g sinθ

The reaction of load L is 0 (no horizontal force), and the reaction of load R is 10 kN (vertical upward force).

To determine the reactions of the loads L and R, consider the equilibrium of the forces acting on the structure.

First, analyze the vertical equilibrium. The sum of the vertical forces must be zero:

ΣFy = R − 7 kN − 3 kN

ΣFy = 0

This gives:

R = 10kN

Next, analyze the horizontal equilibrium. The sum of the horizontal forces must be zero:

ΣFx = L

ΣFx = 0

This indicates that there is no horizontal force acting on the structure.

Therefore, the reaction of load L is zero (no horizontal force), and the reaction of load R is 10 kN (vertical upward force).
