They're equal.

Ignoring air resistance, any object you're not holding onto has the same, constant acceleration ... 9.8 m/s^2 down ... from the moment it leaves your hand until the moment it hits the ground.

It doesn't matter how heavy the object is, and it doesn't matter whether you throw it up, down, or sideways, or just let go and let it drop.

The gravitational potential energy when launched is greater than the potential energy at the peak.  we can explain that gravitational potential energy is the energy possessed by an object due to its position in a gravitational field. When a particle is launched upwards,

the gravitational potential energy at the peak is still less than the potential energy when the particle was launched. This is because the gravitational potential energy is directly proportional to the height from the reference point (usually the ground). At the peak of the trajectory, the particle has a greater distance from the ground and hence a higher potential energy. But at the same time, it also has a lower distance from its starting point, and therefore, a lower potential energy compared to when it was launched.


When the  particle is launched, it has an initial height (h1), and when it reaches the peak of its trajectory, it has a final height (h2).  Since the particle has risen to the peak of its trajectory, it's clear that h2 > h1. GPE1 = m * g * h1 (at launch) are   GPE2 = m * g * h2 (at peak) As h2 > h1 and mass (m) and gravity (g) remain constant, it is evident that GPE2 > GPE1. Therefore, the potential energy at the peak is greater than the gravitational potential energy when launched.

When driving a string at a given frequency while increasing the tension by a factor of 4, the velocity increases by a factor of 2. Option 2 is Correct.

As a result, the frequency doubles. The frequency of a vibrating body reduces with increasing mass, but increases with increasing tension. The frequency rises as the tension rises because the wave speed increases.

Since frequency closely correlates with the square root of stress, when tension rises, frequency rises as well. As you point out, increasing the tension shortens the wavelength in air but does not, contrary to what the book claims, lengthen the wavelength on the string. Option 2 is Correct.

Answer:

RT = 35 Ohms

Explanation:

Let the three resistors be R1, R2 and R3 respectively.

Given the following data;

R1 = 14 Ohms

R2 = 12 Ohms

R3 = 9 Ohms

To find the total resistance, RT;

Since all the resistors are connected in series, the total resistance is equal to the sum of all three resistance of the resistors.

RT = R1 + R2 + R3

Substituting into the equation, we have

RT = 14 + 12 + 9

RT = 35 Ohms.

Therefore, the total resistance of the circuit is 35 Ohms.

Magnitude of acceleration

Explanation:

We know that acceleration can increase depending in the force applied on an object, any object with a greater mass will apply a greater force. F = M(a).

This Newton's second law establishes a relationship between the summary of the external force and the acceleration of the body,  It is demonstrated with the change in the direction and magnitude of the acceleration in the experiment

Newton's second law establishes a relationship between the net force and the acceleration, according to the expression

          ∑ F = m a

where ∑F is the sum of the external forces, m the mass and the acceleration of the body

In this case we have an initial situation, the block and a baking mass, therefore an acceleration is created towards the hanging mass given by

           W₁ = M₁ g

            F = ma

          M₁ g = m a

          a = \(\frac{M_1}{m} \ g\)

where W₁ and M₁ are the weight and the masses of the mass of the body hanging under the acceleration of gravity.

In the second case, perhaps you have two masses, one on each side,

         ∑ F = W₁ -W₂

          ∑F = (M₁ -M₂) g

let's use Newton's second law

          (M₁ -M₂ ) g = m a

           a = \(\frac{M_1 - M_2}{m} \ g\)

We can see that in the second case the acceleration depends on the difference of the hanging masses. This is a proof of Newton's second law where the effect on acceleration is due to the sum of all external forces and not of each force individually.

Answer:

its speed will be less than V

Explanation:

When the ball falls a distance d, its final kinetic energy plus rotational kinetic energy of the drum equals its initial potential energy.

K = U

With its speed V at the end of d, we have

1/2mV² + 1/2Iω² = mgd where I = rotational inertia of drum and balls, ω = angular speed of drum and balls and m = mass of box

1/2mV² + 1/2Iω² = mgd

1/2mV² = mgd - 1/2Iω²

V² = [2(mgd - 1/2Iω²)/m]

V = √[2(mgd - 1/2Iω²)/m]

When the four balls are moved inward closer to the drum, their rotational inertia increases and also its angular speed which thus causes an increase in rotational kinetic energy. But, since the box still falls the same distance of d, its final kinetic energy plus rotational kinetic energy of the drum plus balls still equals its initial potential energy

K = U

I' = new rotational inertia of drum and balls, ω' = new angular speed of drum and balls

With its new speed is now V' at the end of d,

1/2mV'² + 1/2I'ω'² = mgd

1/2mV'² = mgd - 1/2I'ω'²

V² = [2(mgd - 1/2I'ω'²)/m]

V' = √[2(mgd - 1/2I'ω'²)/m]

Since I' and ω' increase, the rotational kinetic energy of the drum and balls (1/2I'ω'²) increases. Thus, the difference (mgd - 1/2I'ω'²) < (mgd - 1/2Iω²) which implies that the kinetic energy of the box decreases. Hence, since its kinetic energy decreases, its speed V' also decreases.

So,  V' < V

So, its speed will be less than V.

Answer:

Explanation:

Apply:

C = A e0 / d

Where:

C = capacitance = 1pf = 1 x10^-12 F

A = area

ε0 = 8.85×10^-12

1 pf = 1 x 10^-12 F

A = Cd / ε0 = 1 x 10^-12 ( 1 x 10^-4 ) / 8.85×10^-12 = 1.13 x10 ^-5 m^2

Using energy concepts, The speed of m3 after it moves down 4.5 m is 66.15 m/s.

Mass of the objects;

m1= 5 kg

m2= 10 kg

m3=15 kg

Distance: h = 4.5m

The change in gravitational potential energy of the mass must same with the change in kinetic energy of the mass. So:

(m3-m1) ×g×h=(15-5) ×9.8×10^-2×4,5 =½×(m1+m2+m3) ×v²

=10×9.8×10^-2×4, 5=0, 5 × (5+10+15) ×v²

v= 66.15 m/s

Batteries and human fatigue are both affected by energy. Energy is the ability to do business (work) and experience change. These changes can be in the form of changes in position, changes in motion, changes in temperature, changes in the state of matter, even changes in living things, such as growth and development are also included in it.

If the energy runs out, then an object will not be able to do work (effort). Humans can feel tired after doing activities, because humans use energy. So, humans rest and consume food and drink to restore lost energy.

According to the information we can infer that the travel angle is called a "drag" angle.

In welding terminology, the travel angle refers to the angle between the axis of the electrode and the workpiece surface. When the top of the electrode leads the welding end (meaning the electrode is inclined downward at an angle) and the welding arc is pointing back toward the weld bead, it is known as a "drag" angle.

In this configuration, the electrode is dragged along the surface of the workpiece, creating a trailing arc direction.

τ = rFsinθ

r = distance from pivot (meters)

F = force (N)

In this case, the forces are the weight of the children. Also, we can leave the distance in centimeters for this type of problem, but others do require a conversion to meters.
