1. The speed is at a constant rate same with the acceleration and velocity
2. When there getting close to the top there speed, acceleration, and velocity all start to decrease
3. The speed and acceleration and velocity all on the way down drastically increase number
hope I helped
Its average speed is 80 miles per hour because 75 minutes=1.25 hours, and the police car travels 80 miles in 1.25 hours, so I just need to take 100 divided 1.25 equal 80. As a result, the police car travels 80 miles in one hour. Hope it help!
Answer:
The momentum of the two-block system is 18 kg-m/s
Explanation:
It is given that,
Mass of block A, 
Mass of block B, 
Velocity of block A, 
Velocity of block B, 
(it is moving in opposite direction)
We need to find the momentum of two block system. It is given by the product of mass and velocity for both blocks i.e.
p = -18 kg-m/s
So, the momentum of two block system is 18 kg-m/s. Hence, this is the required solution.
<u>Answer:</u>
True.
The equation is balanced.
<u>Explanation:</u>
A balanced equation of any particular reaction is often identified when the significant total number of atoms in each of the significant elements present in the reactant side often quoted as the left side is identically same as the number of atoms present in the adjacent side which is the product side also known as right side of the present reaction. Hence it generally implies for a balanced equation to be, the number of moles on one side of the reactant side as well as the product side should also be similar i.e equal.
Example
Here,
No of atoms present in reactant side = 2
No of atoms present in product side= 2
Therefore, Atoms present in the reactant side= atoms present in the product side
Hence, the equation mentioned above is chemically balanced on both sides.
