From what I have been told, the four basic forces regarding physics are the strong or powerful force, a gravitational force, an electromagnetic force, and a weak force. The strong force binds nuclei. Weak forces take care of nuclear decay. Electromagnetic forces exists when two or more objects have an electric charge like a magnet or positive and negative, negative and positive And gravitational forces is just gravity. What holds us down.
Answer:
You put the rock in a graduated cylinder and measure how many milliliters it goes up.
Explanation:
Answer:
it transforms it into high carbon alloy that is harder and can be sharper but is also more brittle in the process.
Explanation:
The rate of solution is the rate at which a substance dissolves.
the factors on which the rate of solution depends are :
particles area of the solute: greater the area , greater is the rate of solution.
stirring: stirring increases the rate of solution.
temperature: increasing temperature increases the rate of solution.
hence the correct choice is
d) how fast a substance dissolves
Explanation:
Given that,
Initial speed of the car, u = 88 km/h = 24.44 m/s
Reaction time, t = 2 s
Distance covered during this time, 
(a) Acceleration, 
We need to find the stopping distance, v = 0. It can be calculated using the third equation of motion as :
s = 74.66 meters
s = 74.66 + 48.88 = 123.54 meters
(b) Acceleration, 
s = 37.33 meters
s = 37.33 + 48.88 = 86.21 meters
Hence, this is the required solution.
