tbh i rlly dont know what makes me me :)
You would use the equation Q=cmΔT, where Q is the amount of heat added, c is the specific heat of the substance (or the amount of heat needed per unit of mass to raise the temperature by one degree Celsius), m is mass, and <span>ΔT is the change in temperature. In this case, Q, heat added, would be equal to (1)(90)(86), which equals 7740 calories.</span>
Physics
Chemistry
Physical science is science which studies non-living things.This covers things on earth to the universe.The main branches are physics and chemistry.The other sub-branches are Astronomy, meteorology and Geology.Physics is concerned with the basic principals of matter and energy.It covers concepts in motion, energy, force, pressure , light and many other areas we encounter in our day to day life.Chemistry is concerned with composition of matter and how it reacts.Material in chemistry is understood through observing molecules, atoms, elements and their interaction in nature including their properties.Chemistry is further divided into organic chemistry and natural chemistry sub-branches.
Hope this helps you!!!
Chlorine is very toxic if inhaled. It is also very corrosive on contact with the skin, eyes, etc.
Answer:
1.63 m/s
Explanation:
a = acceleration of the ball
d = stopping distance = 23.5 - 5.10 = 18.4 ft = 5.61 m
v₀ = initial velocity of the car = 1.45 m/s
v = final velocity of the car = 0 m/s
Using the equation
v² = v₀² + 2 a d
0² = 1.45² + 2 a (5.61)
a = - 0.187 m/s²
To win the tournament :
a = acceleration of the ball = - 0.187 m/s²
d = stopping distance = 23.5 ft = 7.1 m
v₀ = initial velocity of the car = ?
v = final velocity of the car = 0 m/s
Using the equation
v² = v₀² + 2 a d
0² = v₀² + 2 (- 0.187) (7.1)
v₀ = 1.63 m/s
