Answer:843.75kg
Explanation:
kinetic energy(ke)=432000j
Velocity(v)=32m/s
Mass(m)=?
Ke=(mxv^2)/2
432000=(mx32^2)/2
432000=(mx32x32)/2
Cross multiplying we get
432000x2=(mx1024)
864000=1024m
Divide both sides by 1024
864000/1024=1024m/1024
843.75=m
m=843.75kg

Answer:
The ideas resemble their causes are the ideas of: Primary qualities: texture, number, size, shape, motion.
Explanation:
There will be exchange of heat in the system, the tub filled with ice will gain heat, while the bottle of liquid will lose heat.
The flow is made possible by means of convection which implies heat flow from region of higher concentration to region of low concentration
by actual movement of material particles
There are basically three modes of heat transfer
- Radiation
- Convection
- Conduction
