Answer:
v = 27 m/s
Explanation:
To find the speed of cars after the collision you take into account the momentum conservation law. Total momentum of both cars before the collision must be equal to the total momentum of both cars after the collision.
After the collision both cars traveled together, then you have:
(1)
m1: mass of the Toyota = 3-ton = 3000 kg
m2: mass of the taxi = 2-ton = 2000kg
v1: speed of the Toyota before the collision = 45m/s
v2: speed of the car before the collision = 0 m/s (it is at rest)
v: speed of both cars after the collision = ?
You solve the equation (1) for v:
Next, you replace the values of the rest of the variables:
hence, just after the collision both cars have a speed of 27m/s
Yes it would hope i helped !
Answer:
1. E=5320.3J
2. E= 1773.45J
3. E=6.76*10^{-21}J
4. E=2.25*10^{-21}J
Explanation:
1. the thermal energy is given by the formula
where KB is the Boltzmann's constant, T is the temperature and N is the number of molecules in the system.
2. Each degree of freedom contains one half of the total energy. Hence, the energy for one degree of freedom is
3.
4.
Hope this helps!!
I think the first one is 40*40
centimeter or millimeter.
Explanation:
The unit of length most suitable for measuring the thickness of a cell phone is centimeter or millimeter.
Length refers to how long a material is.
- There are different units of length.
- Smaller units that are microscopic are used to measure length dimensions that are very small
- For example, nanometre is used to express microscopic length values.
- Centimeters and millimeters are used for small dimensions that we can easily see.
- Longer lengths can take the order of a yard, kilometer, miles e.t.c
