what vehicle component transfers engine torque to the axles allowing the wheels on the same axle to turn at different speeds
Differentials are the components of a car that transfer engine torque to the axles allowing the wheels on the same axle to turn at different speeds.
There are two differentials in a car. The first one is located on the rare wheels and the second one is located on the front wheels.
The purpose of differentials is to allow the wheels to turn at different speeds required when the car is making a turn. The differentials send the torque from the transmission to the drive wheels.
During the turn, the differentials allow the front and rare wheels to turn at different speeds.

What is the difference between chemical and physical properties?
Why is melting point a physical property?
this is urgent
Answer:
1-physical properties, and chemical properties.
2-The physical properties of matter are those characteristics that can be measured without altering the atomic structure, while the chemical properties of matter are those.
3-For the change of state to occur, the temperature must be constant. The melting point is an intensive physical property of matter; this means that it is not linked to the amount of substance or the size of the body.

Which statement accurately describes the charge of the nucleus of an atom? (2 points)
O a The nucleus can be either positively charged or neutral.
Ob
The nucleus never has an electrical charge.
O c
The nucleus always has a positive charge.
Od
The charge of a nucleus can change from positive to negative.
The nucleus of an atom will have a positive charge due to the existence of protons, which are positively charged subatomic particles.
Protons and neutrons are present in an atom's nucleus. We are aware that a proton has a charge of + 1 and a neutron has a charge of 0 (or no charge). As a result, the atom's nucleus will always be positively charged. A nucleus is a name for the dense area in the middle of an atom. Because there are positively charged subatomic particles present, the nucleus usually has a positive charge. The subatomic particles, which are present in atoms but far smaller than atoms, are there. Protons, neutrons, and electrons are the three primary subatomic particles found in matter. An atom's nucleus contains protons and neutrons, while its outermost nucleus contains electrons. Neutrons are subatomic particles with a charge of zero, whereas protons are positively charged.
Therefore, the nucleus of an atom will always have a positive charge. Consequently, an atom's nucleus has a positive charge because of the presence of protons.

A spaceship of mass 2.40x10⁶kg is to be accelerated to a speed of 0.700 c. (a) What minimum amount of energy does this acceleration require from the spaceship's fuel, assuming perfect efficiency?
The minimum energy required is 3.02 x 10²³ joule.
We need to know about relativistic energy to solve this problem. The rest energy of the object can be determined by
Eo = m₀ . c²
where Eo is rest energy, m₀ is rest mass and c is the speed of light (3 x 10⁸ m/s).
The total energy of object can be described as
E = Eo / √(1 - v²/c²)
where E is total energy, v is the object speed.
From the question above, we know that :
m₀ = 2.4 x 10⁶ kg
c = 3 x 10⁸ m/s
v = 0.7c
Find the rest energy
Eo = m₀ . c²
Eo = 2.4 x 10⁶ . (3 x 10⁸)²
Eo = 2.16 x 10²³ joule
Determine the total energy
E = Eo / √(1 - v²/c²)
E = 2.16 x 10²³ / √(1 - (0.7c)²/c²)
E = 2.16 x 10²³ / 0.71
E = 3.02 x 10²³ joule

What is supernova?A supernova is the enormous, dazzling explosion of a star. Supernovae or supernovas are the plural forms of its abbreviation, SN or SNe. This brief astronomical event occurs either in the latter stages of the formation of a large star or when a white dwarf is set off into uncontrolled nuclear fusion. The original object, referred to as the progenitor, either falls into a neutron star or a black hole, or entirely disintegrates. Before fading over the course of several weeks or months, the optical luminosity of a supernova can reach a peak that is similar to the luminosity of an entire galaxy. The latest supernova in the Milky Way to be directly observed was Kepler's Supernova in 1604, however more recent supernova remnants have been found.

A car traveling on a straight road at 10 meters per second accelerates uniformly to a speed of 21.0 meters per second in 12.0 seconds. The total distance traveled by the car in this 12.0-second time interval is?
Answer:
185.3m
Explanation:
Given parameters:
Initial velocity = 10m/s
Final velocity = 21m/s
Time = 12s
Unknown:
Total distance traveled by the car = ?
Solution:
To solve this problem, we use that appropriate motion equation:
v² = u² + 2as
v is the final velocity
u is the initial velocity
a is the acceleration
s is the unknown distance
t is the time taken;
acceleration = [tex]\frac{v - u}{t}[/tex]
a = [tex]\frac{21 - 10}{12}[/tex] = 0.92m/s²
now;
v² = u² + 2as
21² = 10² + 2(0.92)(s)
441 = 100 + 1.84s
441 - 100 = 1.84s
s = 185.3m

The ideas of Bernoulli's Theorem and the continuity equation are involved in this query. Finding the pressure difference requires substituting the appropriate values.
What is Bernoulli's theorem explain?
Therefore, Bernoulli's theorem states that a drop in fluid pressure is connected with an increase in fluid velocity if the fluid flows horizontally so that there is no change in gravitational potential energy.
Bernoulli's theorem states that as long as an ideal liquid is incompressible, viscous, and flows in a streamline, the total amount of energy it possesses at any given place remains constant. Kinetic, potential, and pressure energy all add up to a constant. P+21pv2+pgh=Constant.

All animals exhale carbon dioxide out through respiration and increase the level of carbon dioxide in the atmosphere and this is intaken by the plants for photosynthesis.
What is carbon cycle ?Carbon cycle is the geological process that balance the amount of carbon dioxide in the atmosphere and biosphere. Carbon dioxide is an essential gas that maintains the living condition on earth.
All animals inhales oxygen and exhales carbon dioxide out. This carbon dioxide is used by plants to carry photosynthesis in plants. Plants absorb this carbon dioxide and combine with water forming oxygen gas and glucose.
This process repeats cyclically and the level of oxygen and carbon in the atmosphere gets balanced. Therefore, animals have a significant role in carbon dioxide cycle and oxygen cycle.

a crude approximation of voice production is to consider the breathing passages and mouth to be a resonating tube closed at one end. what is the fundamental frequency ????1 if the tube is 0.240 m long, by taking air temperature to be 37.0∘c? ????1
The fundamental frequency of the tube is 0.240 m long, by taking air temperature to be [tex]37^o[/tex]C is 367.42 Hz.
A standing wave is basically a superposition of two waves propagating opposite to each other having equal amplitude. This is the propagation in a tube.
The fundamental frequency in the tube is given by

At the moment the two pulses completely overlap on the string, what happens? (a) The energy associated with the pulses has disappeared. (b) The string is not moving. (c) The string forms a straight line. (d) The pulses have vanished and will not reappear.

A single disturbance that travels via a transmission medium is referred to as a pulse. This medium might be formed of stuff or a vacuum, and it might be endlessly large or finite in size.
Consider two pulses that are identical in shape and proceed in opposite directions along a string, with the exception that one has positive displacements of the string's elements while the other has negative displacements.
On the string, the two pulses blend together completely.
The pulses completely balance one another out in terms of removing string elements from equilibrium, yet the string still moves. Shortly after the string is once again shifted, the pulses will have passed each other.

a pitcher throws a .015 kg baseball from rest to a final velocity of 45. what is the magnitude of the change in momentum of the baseball
Answer:
0.675 kg m/s
Explanation:
Momentum = mass x velocity

P.S. I'm not sure of this answer, so it might be a good idea to check this with some other sources.
Change in momentum = 0.675 kg m/s
What is momentum ?
Momentum is a property of a moving body that the body has by virtue of its mass and motion and that is equal to the product of the body's mass and velocity
change in momentum = final momentum - initial momentum
final momentum = m*v = 0.015 * 45 = 0.675 kg m/s
