1: a machine makes our work easier
2: a machine can help us find important information
3: a machine can help us transport from a place to another
Weight=mass x gravitational force
W=60 x 1/100 x 10
W=60 x 0.1
W=6N
Answer:
0.0118125 (kg)
Explanation:
mass = density x volume
First, find the volume of the cube as you're already given the density. You're also given the length of the cube, 1.5 cm. You need to convert this to m since the density's unit is kg/m^2
1.5cm x (1m/100cm) = 0.015m
Since Volume = (length)^3,
Volume of the cube = (0.015)^3
Volume of the cube = 3.375*10^-6
So mass of the cube = (3500)(3.375*10^-6) = 0.0118125 (kg)
Answer:
The inverse(opposite) relationship between absolute pressure and the volume of a gas. This is known as Boyle's law.
Explanation:
The temperature must be kept the same in a closed system.
Answer:
KE= 1/2mv^2= 1/2*0.0042kg*993m/s= 2.0853joule
