Answer:
4m
Explanation:
Using the kinematic equation;
For the first stage when the car is initially moving at 0.5m/s
definitely u = 0.5 m/s and v = 0
The cart comes to rest after traveling I m, ∴ (s) = 1m
the acceleration of the car can be expressed by applying the kinematic equation:
making "a" the subject of the formula; we have:
a = 0.125 m/s²
The experiment is repeated on the same track, but now the cart is initially moving at I m/s
i.e v = 1 m/s and u=0
S = 4 m
∴ the cart traveled 4m before coming to rest.

X≤10: The definition of nuclear fusion says: a reaction in whicih 2 OR MORE atoms come close enough together to form one or more different atomic nuclei and subatomic particles.
x=the number of atoms at the end
Answer:
(a) Distance traveled = 75.3846 m
(b) Velocity of car at that instant will be 14 m/sec
Explanation:
We have given acceleration of the car
Initial velocity of the cart u = 0 m/sec
(a) According to second equation of motion we know that
So distance traveled by car
As the truck is moving with constant speed
So distance traveled by truck
As the truck overtakes the car
So
So distance traveled
(b) From second equation of motion we know that v = u+at
So v = 0+1.3×10.769 = 14 m /sec
Hey there!
In this case, it is possible to solve this problem by using the widely-known steam tables which show that at 90 °C, the pressure that produces a vapor-liquid mixture at equilibrium is about 70.183 kPa (Cengel, Thermodynamics 5th edition).
Moreover, for the calculation of the volume, it is necessary to calculate the volume of the vapor-liquid mixture, given the quality (x) it has:
Thus, since 8 kg correspond to liquid water, 2 kg must correspond to steam, so that the quality turns out:
Now, at this temperature and pressure, the volume of a saturated vapor is 2.3593 m³/kg whereas that of the saturated liquid is 0.001036 m³/kg and therefore, the volume of the mixture is:
This means that the volume of the container will be:
