Answer:
Their change in momentum is the same in magnitude and opposite in direction
Explanation:
The momentum of an object is defined as:
where
m is the mass of the object
v is the velocity of the object
Therefore, the change in momentum of an object is
where is the change in velocity.
During a collision, the force experienced by an object is equal to the rate of change of momentum:
where is the duration of the collision.
According to Newton's third law of motion, the force exerted by vehicle 1 on vehicle 2 during the collision is equal (and opposite) to the force exerted by vehicle 2 on vehicle 1, so
Which means
And since the duration of the collision is the same for the two vehicles, this becomes
D. Direction, if someone is traveling on an interstate from New York to Boston at 65 MPH, the speed of the car is 65 MPH and the velocity is 65 MPH north-east.
The area between the thorajand pelvis in humans constitutes the part of the body
known as the SPINE
To solve this problem it is necessary to apply the concepts related to the thermal transfer rate. In general, the transfer rate can be expressed as
Where,
k = Thermal conductivity
A = Cross-sectional area
= Change of temperature
L = Length
Since the two heat transfer rates are equivalent we have to:
Replacing we have,
Therefore the temperature where the two bars are joined together is 300°C
Complete Question
Consider a system consisting of an ideal gas confined within a container, one wall of which is a movable piston. Energy can be added to the gas in the form of heat by applying a flame to the outside of the container. Conversely, energy can also be removed from the gas in the form of heat by immersing the container in ice water. Energy can be added to the system in the form of work by pushing the piston in, thereby compressing the gas. Conversely, if the gas pushes the piston out, thereby pushing some atmosphere aside, the internal energy of the gas is reduced by the amount of work done.
so the absolute temperature T is directly proportional to the product of the absolute pressure p and the volume V,Here n denotes the amount of gas moles,which is a constant because the gas is confined and R is the universal constant
What is the as the system of ideal gas goes from point A to point B on the graph recall u is proportional to T
Answer:
The gas A and B have same internal energy
Explanation:
From the question we are told that
Generally the equation of temperature is mathematically given as
And
Generally the change in temperature is mathematically given as
Generally the change in internal energy
Therefore with
The gas A and B have same internal energy
