55 miles=88513.9 m so A is 88,000 m/hr.
55 miles=88.5139 km and 1 hr=60 sec so B is 88.5139/60 which is 1.5 km/s
88513.9/60=1400 m/s

If you are using a wrench to loosen a very stubborn nut, you can make the job easier by using a "cheater pipe." This is a piece
pentagon [3]

Answer:

Explained

Explanation:

The cheater pipe extends the wrench in  radial direction, providing a larger momentum for the force you exert.

For a given force the torque exerted with the cheater pipe is larger.

Mathematically we can write that

τ = r×F and τ'= r'×F

now since r'> r

⇒ F'>F

Answer:

Water breaking down into hydrogen and oxygen is a decomposition reaction

Hydrogen and oxygen combining to form water is a synthesis reaction

Explanation:

A decomposition reaction is a chemical reaction that involves the breakdown of a chemical reactant entity into two or more simpler product fragments

Water H₂O undergoes a decomposition reaction by breaking down into hydrogen, H₂,, and oxygen, O₂, as follows;

2H₂O (l) → 2H₂ (g) + O₂ (g)

A synthesis reaction is a reaction that involves the chemical combination of two or more dissimilar molecules or atoms to produce a different compound or molecule

Water, H₂O, is formed by a synthesis reaction of hydrogen, H₂,, and oxygen, O₂, combining as follows;

2H₂ + O₂  → 2H₂O

A speeding car traveling at 24.8 m/s passes a police car that is at rest. The police car begins its pursuit at the instant the s
marusya05 [52]

Answer:

the acceleration required is 1.37m/s^2

Explanation:

The car is having a constant velocity movement, so if we calculate the time to reach 897m, we can use it to find the acceleration the policeman need to apply to reach the car.

x=v*t\\t=\frac{x}{v}\\t=\frac{897m}{24.8m/s}\\t=36.17s

the policeman is traveling with a constant acceleration starting from rest so:

x=\frac{1}{2}*a*t^2\\\\a=\frac{2*x}{t^2}\\\\a=1.37 m/s2
