Answer:

3.46 m/s

Explanation:

This is actually a Physics question and not a Business question.

According to the property of conservation of momentum, the speed of the Mazda before the collision multiplied by the mass of the Mazda must equal the speed after the collision multiplied by the mass of both cars:

m_1v_1=(m_1+m_2)*v_2\\940*12.5=(940+2460)*v_2\\v_2= 3.46\ m/s

The post-collision speed of the two entangled cars is 3.46 m/s.

Which of the following is not an example of how media coverage of the Space Race affected the economy?

Reptile [31]

Answer:

True

Explanation:

A single use plan is basically a one time business transaction that is supposed to take place only once and should not be repeated in the future.  In this case, the production plant has been used for more than 100 years, but once it is sold, its history and the company should no longer have any type of relationship with it.

A sample of gas occupies 575 ml at 1.50 atm and 125 degrees celsius. if temperature is changed to 20 degrees celsius and volume
Anastaziya [24]

A sample of gas occupies 575 ml at 1.50 atm and 125 degrees Celsius. If the temperature is changed to 20 degrees Celsius and the volume is changed to 0.300 L. The will be a new pressure at 2.12 atm.

Temperature is the measure of hotness or coldness expressed in phrases of any of numerous scales, including Fahrenheit and Celsius. Temperature shows the route wherein heat energy will spontaneously waft—i.e., from a hotter frame (one at a higher temperature) to a less warm body (one at a decreased temperature).

The common body temperature is ninety-eight.6 F (37 C). however normal frame temperature can vary between ninety-seven F (36.1 C) and 99 F (37.2 C) or more. Your frame temperature can range depending on how active you are or the time of day.

The heat of an item is the entire strength of all of the molecular motion interior of that item. Temperature is the degree of the thermal energy or average warmth of the molecules in a substance. SI Unit

V₁ = 0.575L

P₁ =1. So atm.

T₁ =125 + 273=398 k

√2 =0.300 L

P₂ =?

T₂ = 20 +273= 293K

P1XV 1=T2

1.50 X 0.575 lit=398 K

P2 x 0.300 lit =293K

1-50 atm x 293KX 0.575 lit

0. 300 lit X 396 K

P₂ =2.1165 atm
