Answer:
Friction
Explanation:
Friction keeps things from sliding into things according to newton's laws
Answer:
The answer is D, boxes 1, 2 and 3
Answer:
Option B
Explanation:
Weight can be measured in pounds. Pounds is a unit of weight.
=> Mass is measured in kgs
=> A bowling ball has more mass than a golf ball.
=> Objects do not have the same weight regardless of where they are. The weight depends on where they are as it depends on the acceleration due to gravity (g)
Explanation:
Filtration is the easiest filtering method used in forensic science, and it is commonly used to extract objects from a mixture by either going through a "top filter" that is like a sieve, collecting any solid particles that can be retrieved and inspected for any incriminatory evidence.
They glance to see whether the density of glass objects found on a suspicious matching glass discovered at a scene of the crime. When it does, the evidence indicates that the perpetrator was at the scene.
The solution for this problem:
PV = nRT
But we are looking for n so, alter the original formula:
n = PV / RT
= (1.00 atm) x (2.09 x 10^8 L) / ((0.08205746 L atm/K mol) x (25.1 + 273.15 K))
= 8539801.26 mol H2
total volume = (8539801.26 mol H2) x (-286 kJ/mol H2) = -2.44 x 10^9 k J
