Answer:
666.67 kg is the mass of a car.
Explanation:
Momentum is defined as amount of motion possessed by the the moving body. It is mathematically calculated by multiplying mass into velocity by which object is moving.

Mass of the car = m =?
Velocity of the car = v = 15.0 m/s
Momentum of the car = P = 10,000.00 kgm/s


666.67 kg is the mass of a car.
your answer will be :
B. <u>Na has a lower</u> <u>electronegativity than H</u>
because Na belongs to alkali metals which are least electronegative (most electro positive) but hydrogen is a non metal, it has higher electronegativity as compared to metals like Sodium (Na).
Answer:
239.45 K
Explanation:
Ideal gas law formula is P1V1T2=P2V2T1
Rearrange that to get...
T2=T1P2V2/P1V1
Fill in the values and solve.
