The muffler smooths out the pressure pulses in the exhaust system, allowing them to be released at an even and constant rate.
An exhaust system is a system used by an engine to channel out gasses created when the fuel and air are burned in the combustion chamber.
Some components of an exhaust system include:
clampsoxygen sensor andMufflersThe muffler of the exhaust system helps it to achieve its functions which include it:
control noise, carry away gases, improve engine performance and improve fuel consumptionThe muffler are used mainly to dissipate the loud sounds created by the engine's pistons and valves.
Therefore, muffler smooths out the pressure pulses in the exhaust system, allowing them to be released at an even and constant rate.

Explanation:
how much energy is needed to raise the temperature of 2kg of copper from 0°c to 10°c. the specific heat capacity of copper is 380j/kg°c
Explanation:
H= mass× specific heat capacity×change in temperature
=2×380×(10-0)
=2×380×10
=7600Joules
According to the specific heat capacity, 7600 joules of energy is required to raise temperature of 2 kg copper from 0-10 degree Celsius.
What is specific heat capacity?Specific heat capacity is defined as the amount of energy required to raise the temperature of one gram of substance by one degree Celsius. It has units of calories or joules per gram per degree Celsius.
It varies with temperature and is different for each state of matter. Water in the liquid form has the highest specific heat capacity among all common substances .Specific heat capacity of a substance is infinite as it undergoes phase transition ,it is highest for gases and can rise if the gas is allowed to expand.
It is given by the formula ,
Q=mcΔT
In the given problem,energy is calculated as, Q=2×380×(10-0)=7600 J.
Thus, 7600 joules of energy is required to raise the temperature of 2 kg of copper from 0°C to 10°C.

A bicycle will move backward.A car will move in the same direction.A ball will have sideways due to unbalanced force.What is Unbalanced Force?Unbalanced force is defined as the forces which are not equal in magnitude. When two forces with different magnitudes are applied on an object from opposite directions, the object will start moving in the direction of the net force.
These forces result in the motion of an object.
Balanced forces are the forces which are equal in magnitude. When two forces with equal magnitude are applied on an object from opposite directions, the object will not start moving.
These forces does not result in the motion of an object.

An arrow is launched from a bow with an initial horizontal velocity of 40
m/s and an initial vertical velocity of 62 m/s. What is the total initial vector
velocity of the arrow?
Answer:
V = (Vx^2 + Vy^2)^1/2 = (40^2 + 62^2)^1/2
V = 73.8 m/s
tan theta = Vy / Vx = 62/40 = 1.55
theta = 57.2 deg

If an object falls from rest and lands 3.2 seconds later, how many
meters did it fall
Answer:
50.2 meters
Explanation:
When an object falls, it goes a distance d in time t according to the formula:
[tex]d=\frac{1}{2}*g*t^{2}[/tex]
d is the distance in meter, g is the acceleration due to gravity with the value of 9.8[tex]m/s^{2}[/tex] , t is the time in seconds
Therefore, [tex]d = \frac{1}{2}*9.8*(3.2)^{2}[/tex]
d= 50.176 ≈ 50.2m

The distance traveled by the canoe in the water is 0.93 m.
The given parameters;
mass of the dog, m = 4.0 kgmass of the canoe, = 21 kgdistance traveled by the dog, d = 4.9 mApply the principle of conservation of linear momentum to determine the distance traveled by the canoe;
[tex]m_1v_1 = m_2 v_2\\\\m_1(\frac{d_1}{t} ) = m_2(\frac{d_2}{t} )\\\\4(4.9) = 21(d_2)\\\\d_2 = \frac{4(4.9)}{21} \\\\d_2 = 0.93 \ m[/tex]
Thus, the distance traveled by the canoe in the water is 0.93 m.

I NEED ANSWERS ASAP!!!! Which of the following would accelerate faster with the same amount of force?
150 pound person on a skateboard
200 pound person on a skateboard
They all accelerate equally
300 pound person on a skateboard
150 pound person on a skateboard
The 150-pound person on a skateboard would accelerate faster with the same amount of force. Therefore, option (A) is correct.
What is acceleration?Acceleration of a body is demonstrated as the change of velocity with respect to time. The acceleration is a vector parameter as it carries both magnitude and direction. Acceleration is defined as the 2nd derivative of position w.r.t. time and the 1st derivative of velocity w.r.t. time.
According to Newton's 2nd law, the force is equal to the multiplication of the mass and acceleration of an object.
F = ma
and, a ∝ 1/m
From the above equation, we can say that acceleration (a) is inversely proportional to the mass (m) of the body.
In the given option the person with a mass of 150 pounds will accelerate faster with the same amount of force and the person with a mass of 300 pounds will accelerate the least.
