Answer:
Explanation:
Given
Mass of car
Force applied
time period
Acceleration associated with car
Acceleration is the change in velocity w.r.t time
thus, the change in velocity is
Answer:
The acceleration produced is
Explanation:
By the second law of Newton, the force F is equal to:
F = ma
Where m is the mass of the object and a is the acceleration produced. So if The force gives the standard 1 kg mass an acceleration of 1.00 m/s2, that means that the force apply on A and B is equal to:
F = (1Kg) * (1.00m/s2) = 1 N
Then, if this force on A produce an acceleration of 0.530 , the mass of A is:
At the same way, if this force on B produce an acceleration of 0.344 , the mass of B is:
Therefore, if they are attached and the same force is applied, the acceleration is:
Answer:
4520 kJ
Explanation:
To make a substance transition phases an energy must be applied, this is know as the latent heat.
Water has a latent heat of 40.7 KJ/mol to turn into vapor.
The molecule of water has a molecular weight of 18. This means that a mol of water weights 18 grams.
With this we can convert the latent heat to use grams instead of mols
Now, the heat needed to vaporize water is simply:
Q = m * DHvap = 2000 g * 2.26 kJ/g = 4520 kJ
Answer:
18N is the net force
Explanation:
Since friction always acts in the opposite direction of an objects motion we subtract the applied force from the frictional force to get our resultant net force of 18N.
