An object starts with an initial height of 5 meters above the ground. It is thrown upward with an initial velocity of 4 m/s. What is the maximum height the object reaches? What is the object's final velocity as it hits the ground? (use g=9.8 m/s^2)

Answers

Answer 1

The maximum height the object reaches be 5.81 m.

The object's final velocity as it hits the ground be 10.67 m/s.

What is velocity?

The rate at which a body's displacement changes in relation to time is known as its velocity. Velocity is a vector quantity with both magnitude and direction. SI unit of velocity is meter/second.

Given that:

An object starts with an initial height of 5 meters above the ground. It is thrown upward with an initial velocity of 4 m/s.

So, maximum height obtained by it be: H  = 5 m + (4²/2×9.8) m = 5.81 m.

The object's final velocity as it hits the ground = √(2gH)

= √(2×9.8×5.81) m/s

= 10.67 m/s.

define the principal focus of a concave mirror

Answers

The principal focus of a concave mirror is a point on the axis of the mirror at which parallel rays of light are brought to focus after being reflected by the mirror. A concave mirror is a mirror with a curved surface that is shaped like the inside of a bowl, with the center of the curve facing outward. When light rays are reflected by a concave mirror, they are brought to a focus at the principal focus of the mirror. The distance from the center of the mirror to the principal focus is known as the focal length of the mirror. The principal focus of a concave mirror is an important concept in optics and is used in the design and operation of various optical instruments, such as telescopes and cameras.

Answers

Figure shows five identical light bulbs a-e connected to a battery.

Part A: The potential at points 1 and 3 is different because of the internal resistance of B, so B is already glowing.

Part B: If a cut is made at point b, then no bulb will go out because C is already fused.

Part C: If a cut is made on C, then no bulb will go out because D and E were already fused.

What is the potential difference?

When two places in a circuit contain different amounts of charge carriers' energy, this is referred to as a potential difference.

Part A:

Use the concept of potential difference to understand this question.

The bulb will only be lit when there is some potential difference. If the potential difference is zero, then the bulb will not light.

First, redraw the diagram and shown it below:

The potential at points 1 and 3 is different because of the internal resistance of B, so B is already glowing.

Part B

The potential at points 3 and 4 is the same because there is no resistance between them and the potential across C is 3 and 4. So, the potential difference is zero across C and it was already fused.

So, if a cut is made at point b, then no bulb will go out because C is already fused.

Part C

The potential at points 2, 4, 5, and 6 is the same. The potential across D and E is 5 and 6. The potential difference is zero across them, so they were already fused.

If a cut is made on C, then no bulb will go out because D and E were already fused.

Bearings are mechanical elements that limit relative motion to a desired degree and reduce friction between moving parts. The bearing design can, for example, provide free linear motion of the moving part or free rotation about a fixed axis. Alternatively, movement can be prevented by controlling the normal force vector acting on the moving part. Most bearings facilitate the necessary movement by minimizing friction. Bearings are broadly classified according to the type of motion, permissible motion, and the direction of load (force) applied to parts.

Answers

The translational & rotational kinetic energy is :

a) The translational kinetic energy of the disk across the level surface is 17.58J.

b) The rotational kinetic energy of the disk is 8.79J.

How do you find total kinetic energy with translational and rotational?The combined translational and rotational kinetic energies of an item in motion determine its total kinetic energy. 12 mvCM2 is the translational kinetic energy. Rotational kinetic energy is equal to 12 I2. Total kinetic energy is 12mvCM2 plus 12I2.Ek=12mv2, where m is the mass (mass of the molecule, atom, or ion) and v is the velocity of its Centre of mass, is the energy associated with the movement of a chemical entity.There is just one distinction between rotational and translational kinetic energy: translational energy moves in a straight path, but rotational energy does not. When a bicycle is being ridden down a bike path, its tyre provides an illustration of both kinetic and translational kinetic energy.

What is the mass of a ball with a momentum of 18 kg*m/s and a velocity of 9 1 m/s? O 2 m/s O 2 kg O 162 m/s O 162 kg​

Answers

Answer:

B: 2 kg.

Explanation:

To find the mass of an object given its momentum and velocity, you can use the following formula:

mass = momentum / velocity

In this case, the momentum of the ball is 18 kg*m/s and its velocity is 9 1 m/s, so the mass of the ball is:

mass = 18 kg*m/s / 9 1 m/s

= 2 kg

Therefore, the correct answer is B: 2 kg.

what is the maximum speed of a 330 kg car if the spring is compressed the full amount? express your answer with the appropriate units.

Answers

A spring that has been fully compressed can move at a maximum speed of 4.993 m/s. According to kinetic theory, molecules in any system are orientated arbitrarily.

Determine the maximum speed?The weight of the spring is 330 kg, According to kinetic theory, molecules in any system are orientated arbitrarily. The radial and angular components of every molecule are unique.According to theory, the root mean square notion is used to compute energy leakage in any system.An illustration of determining energy dissipation parameters in electronics is zero current.When 3RT = mv2 and v2 = 3RT/m T/m = 1, K.E = 3RT/2 and K.V = mv2.A spring that has been fully compressed can move at a maximum speed of 4.993 m/s.

What is the conservation of mass?

According to the rule of conservation of mass, no atoms are created or destroyed during a chemical process. Instead, the atoms combine in a variety of ways to create goods. This explains why each element has the equal amount of atoms on both sides of an equation with balanced symbols.

According to conservation of mass,

m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂

Given that,

m₁ = 50 kg

m₂ = 75 kg

u₁ = 4 m/s

u₂ = -1 m/s

v₁ = -2 m/s

v₂ = ?

Now, putting the values,

m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂

(50 × 4) + [75 × (-1)] = [50 × (-2)] + (75 × v₂)

or, 125 = -100 + 75 v₂

or, 75 v₂ = 225

or, v₂ = 3 m/sec.

Ultrasound in Medicine. A 1.70-MHz sound wave travels through a pregnant woman's abdomen and is reflected from the fetal heart wall of her unborn baby. The heart wall is moving toward the sound receiver as the heart beats. The reflected sound is then mixed with the transmitted sound, and 72 beats per second are detected. The speed of sound in body tissue is 1500 m/s. Calculate the speed of the fetal heart wall at the instant this measurement is made.

Answers

The speed of the fetal heart wall at the instant is 0.031 m/s when 72 beats per second of hart beat was detected.

The Doppler Effect, defined as the change in frequency of a wave in relation to an observer moving relative to the wave source, must be used.

Let

v= magnitude of the heart wall speed

V= speed  of sound = 1500

fh= the frequency the heart receives (and  reflects) =

fi= original frequency

ff= reflected frequency

fb= frequency for the beats=72

Make use of the Doppler Effect formula.

We have this formula because the heart is a moving observer and the device is a stationary source.

[tex]f_h = [(V+ v)/(v)] fi....(1)[/tex]

We can use this formula if we consider the heart to be a moving source and the device to be a stationary observer.

[tex]f_f = [(V)/(V-v)] fh....(2)[/tex]

The beats' frequency would be the difference between the original and reflected frequencies.

[tex]f_b = f_f -f_i......(3)[/tex]

substituting (1) and (2) into (3),

[tex]f_b=\frac{V}{V-v}\frac{V+v}{V}f_i-f_i\\\\f_b=f_i(\frac{V+v}{V-v}-1)\\\\f_b=f_i\frac{V+v-V+v}{V-v}\\\\f_b=\frac{2v}{V-v}[/tex]

solving for v ,

[tex]v=V\frac{f_b}{2f_i-f_b}=1500\frac{72}{2(1.70*10^6)-72}=0.031 m/s[/tex]

Thus, the speed of fetal heart is 0.031 m/s
