Answer:
So the car was speeding more moving towards North
Explanation:
As we know that during the collision of two cars total momentum before collision and after collision must be conserved
So here we can say that after collision two cars are locked and moved together Exactly towards North-East
So here momentum of two cars must be exactly same before collision in East and North directions
So we will have
So the car was speeding more moving towards North
Thermal energy is added to four identical<span> 1.0 kg </span>samples of water<span> at room temperature. Which of the following </span>increases in each sample<span>? average charge of an electron; average density of </span>a<span> nucleus; average mass of </span>a<span> proton; average speed of </span>a<span> molecule. Your answer: -. Answer: D - average speed of </span>a<span>molecule.</span>
1. a=(v-v0)/t
a=14 m/s / 2s
a=7 m/s^2
2. <span>a=(v-v0)/t
</span>a=(30 m/s - 0 m/s) / 12 s
a=2.5 m/s^2
3. <span>a=(v-v0)/t
a=(37 m/s - 22 m/s) / 2 s
a= 7.5 m/s^2
4. </span><span>a=(v-v0)/t
a=(12 km/s - 0 km/s)/8 s
a=1.5 km/s^2

Answer:
The answer is 4.55 m/s!

Answer:
0.9 cm
Explanation:
The computation in the increase in the length of the joined rod is shown below:
As we know that
Increase in length = increase in the length of aluminum rod + increase in The length of steel rod
= 0.9 cm
We simply added the length of aluminium rod and length of steel rod so that the length of the joined rod could come and the same is to be considered
