Answer:343
Explanation:
The reason a penny thrown straight up inside a bus will come back to your hand is that you, the bus, the air inside the bus, and the penny are all moving at the same velocity.The law of inertia applies to both moving and nonmoving objects.
this is a true or false question help
Answer:
its false
Explanation:
since the penny is thrown straight up its not going to move forwad with you and the bus since it has no forces pushing on it. If the bus wasn't moving it would land back on your hand

whar determines the direction of ocean currents
Answer:
The direction in which they rotate is determined by the hemisphere in which they are located. The main overall global wind patterns, the rotation of the Earth, and the shape of ocean basins are the three major factors that decide surface currents.
Oceanic factors are Tempature, salinity, density, pressure gradient and melting of ice. Atsmopheric factors are atsmopheric pressure, winds, rainfall, evaporation and insolation

When melting of a metamorphic rock occurs, it changes into what?
Answer:
The upper limit of metamorphism occurs at the pressure and temperature of wet partial melting of the rock in question. Once melting begins, the process changes to an igneous process rather than a metamorphic process. During metamorphism the protolith undergoes changes in texture of the rock and the mineral make up of the rock.
Explanation:
i hope this helps
When melting of a metamorphic rock occurs, it changes into Magma and igneous rock will emerge as a result of this..
What is metamorphism?Sedimentary, igneous, and metamorphic rocks are the three distinct types of rocks that make up the rock cycle. Rocks such as sedimentary and igneous rocks were not always rocks.
A very particular set of circumstances must exist for a rock to undergo metamorphism. It is necessary to subject the preexisting rock to extreme temperatures, high pressures, or hot, mineral-rich fluids. All three of these conditions are typically true. The Earth's crust is where these conditions are most frequently encountered, either there or at plate borders when tectonic plates meet.
It is essential that the current rock not melt in order to produce metamorphic rock. The rock will melt under excessive heat or pressure and turn into magma. Instead of a metamorphic rock, an igneous rock will emerge as a result of this.

Starting from rest, this airliner accelerates at 2.4m/s2 for 32 seconds before leaving the ground. Calculate its velocity at liftoff.
Answer:
The velocity will be "76.8 m/s".
Explanation:
The given values are:
Acceleration,
a = 2.4 m/s²
Time,
t = 32 seconds
By equation of motion,
⇒ [tex]v=u+at[/tex]
On substituting the values, we get

A copper atom has an atomic number of 29 and an atomic mass of 64. What
is the structure of this atom?
A. It has a central nucleus composed of 29 protons and 29 neutrons,
surrounded by an electron cloud containing 35 electrons.
B. It has a central nucleus composed of 29 protons and 35 neutrons,
surrounded by an electron cloud containing 29 electrons.
O C. It has a central nucleus composed of 35 protons and 29 neutrons,
surrounded by an electron cloud containing 29 electrons.
D. It has a central nucleus composed of 29 protons and 64 neutrons,
surrounded by an electron cloud containing 29 electrons.
SUBMIT
Answer:
B. It has a central nucleus composed of 29 protons and 35 neutrons,
surrounded by an electron cloud containing 29 electrons.
Explanation:
Protons and neutrons are the only subatomic particles with mass, and they are located in the nucleus. If this atom has an atomic number of 29 and is copper, it must have 29 protons (protons define which element is being observed). This means all remaining mass is from neutrons. 64-29 = 35.
Electrons have no mass and orbit the nucleus in the electron cloud. Since this copper atom is neutral (we are not told it has a charge), there must be an equal number of protons and electrons.
Answer:
B. It has a central nucleus composed of 29 protons and 35 neutrons,
surrounded by an electron cloud containing 29 electrons.

How are amplitude, intensity, and
loudness related?
Answer:
Amplitude is a measure of the size of sound waves. It depends on the amount of energy that started the waves. Greater amplitude waves have more energy and greater intensity, so they sound louder. The same amount of energy is spread over a greater area, so the intensity and loudness of the sound is less.
Explanation:
1.) True or False.
The two forces in an action-reaction pair are always equal in strength.
2.) True or False.
The two forces in an action-reaction pair act in the same direction.
3.) True or False.
Action-reaction force pairs act on the same object.
4.) True or False.
Action-reaction force pairs act simultaneously.
Answer:
Explanation:
According to Newton's third law of motion, forces always act in equal but opposite pairs. Another way of saying this is for every action, there is an equal but opposite reaction. This means that when you push on a wall, the wall pushes back on you with a force equal in strength to the force you exerted. 1.True 2.falues 3.true 4. not really sure on this one

If you use a lever to lift a boulder 0.25m, while applying 350 N on the lever which moves 1.5 m down on your side. What is the weight of the boulder? (F1d1 = F2d2) 87.5 N 131 N 525 N 2100 N
Answer:
2100 N
Explanation:
From the question,
Using the formula
F₁d₁ = F₂d₂..................... Equation 1
Where F₁ = Weight of the Boulder, d₁ = distance moved by the Boulder, F₂ = Force applied on the lever, d₂ = distance moved by the lever.
make F₁ the subject of the equation
F₁ = F₂d₂/d₁.................... Equation 2
Given: F₂ = 350 N, d₁ = 0.25 m, d₂ = 1.5 m
Substitute these values into equation 2
F₁ = 350(1.5)/0.25
F₁ = 2100 N

A car slams into a wall with a force of 5000 N. What is the force of the wall on the car? 5000 N -5000 N 49000 N 510 N It cannot be determined with the information provided.
Answer:
-5000 N
Explanation:
Newtons third law of motion states that action and reaction are equal and opposite. This means that to every action, there is an equal opposite reaction.
Hence when a body A exerts a force FA on another body B, the body B also exerts a force FB on A which is equal in magnitude to FA but opposite in direction. FB is the reaction force due to FA.
Hence, when a car hits a wall with a force of 5000N, the reaction of the wall on the car is -5000N
I was playing goalie in a soccer league and made a save. The ball was traveling at 14 m/s and has a mass of 0.45 kg. How muck kinetic energy did the ball have when it hit me
Answer:
Kinetic energy = 44.1 J
Explanation:
Given:
Velocity of ball = 14 m/s
Mass of ball = 0.45 kg
Find:
Kinetic energy
Computation:
An item's kinetic energy is force it has as a result of its motion. It is the amount of work necessary to move a body of a known volume from rest to a specified velocity.
Ke = (1/2)(m)(v²)
Ke = (1/2)(0.45)(14²)
Ke = (1/2)(0.45)(196)
Kinetic energy = 44.1 J

Explanation:
The mass of mass A the diagram .the frame joining the mass is massless.
What is Mass?The unique location in an object or system that can be used to describe how the system reacts to outside forces and torques is referred to as the "center of mass" or "center of gravity" in a uniform gravity field.
The idea of the center of mass is that it is the average of all the masses divided by the distances between them. With regard to the torques produced, that is comparable to balancing a seesaw around a pivot point in one plane.
Therefore, The mass of mass A the diagram .the frame joining the mass is massless.

What is the wavelength of visible light emitted at 4.2 x 10^8 Answer in units of M
Answer:
0.714 m
Explanation:
From the question,
v = λf......................... Equation 1
Where v = velocity of visible light, f = frequency of visible light, λ = wave length of visible light.
make λ the subject of the equation
λ = v/f.................. Equation 2
Given: f = 4.2×10⁸ Hz
Note: Light is an electromagnetic wave, and all electromagnetic waves travels with the same speed (3×10⁸ m/s)
Constant: v = 3×10⁸ m/s
Substitute these values into equation 2
λ = 3×10⁸/4.2×10⁸
λ = 0.714 m
